On this page

You have a list of a few hundred companies, a new sending domain and twenty tabs of "best cold email software" lists. They disagree on the order, and more often than you would hope, on the prices.

Cold email software sends personalized emails and automatic follow-ups to people who have not signed up for your list, from mailboxes you connect. Most of the tools here also warm those mailboxes up before you send, and several rotate sending across them so one address does not carry every email.

On 10 November 2026, six of Google's top ten US results for "cold email software" sat on a cold email vendor's own domain. The lists from lemlist and Instantly each put their own tool first, and Instantly's quotes an older price for its own Hypergrowth plan. This guide prices eight cold email tools from their own pages, and my own product, which does not send at volume, sits last.

I read every pricing page and the sender rules on 10 November 2026. Nothing was sent and no trial account was opened, so each feature below is described the way the vendor describes it.

Two exits before you start. If your list opted in, you want email marketing software for people who opted in instead. If you do not know who to email yet, begin with finding who to email in the first place.

TL;DR

Eight cold email tools, one line each

Eight cold email tools I priced on 10 November 2026:

  1. Instantly starts at $47 a month billed monthly, with unlimited mailboxes and warmup; lead data is a separate plan.
  2. Smartlead starts at $39 a month billed monthly ($32 on yearly billing) and rotates sending across unlimited mailboxes.
  3. Woodpecker charges $39 a month billed monthly for 5,000 emails, with three warm-ups and unlimited users.
  4. Saleshandy is $34 a month billed annually and includes 1,500 lead finder credits a month, for one user.
  5. lemlist sells its Email plan at $55 a month on yearly billing for unlimited users and senders; data is an add-on.
  6. Apollo is a contact database first: Basic is $49 a seat a month billed annually, and its two cheaper plans send 250 emails a day.
  7. Hunter has a free plan that sends from one mailbox; Starter is $34 a month paid yearly.
  8. GMass works inside Gmail from $29.95 a month billed monthly; sequences start on Premium at $39.95 a month billed monthly.

The prices are for the software. The mailboxes and domains you send from are a separate cost, and Gmail and Yahoo both want your spam rate below 0.3%.

How I compared the cold email tools

Every one of these email outreach tools got the same five questions, asked of its own pricing page:

  • What does the plan meter? Emails a month, contacts or "active prospects", connected mailboxes, warm-up slots, seats, and lead data priced in each vendor's own credits (Apollo's, Hunter's, Saleshandy's). The mix of units differs by vendor, so compare the unit before the price.
  • Is the price on the page, and in which billing state? Five of the eight opened on annual or yearly billing, and Instantly and Woodpecker opened on monthly. GMass's default for a US visitor could not be determined, so I give both of its states.
  • Does it warm up and rotate mailboxes? Cold email warmup comes with most plans here. Two of the eight name no warm-up feature at all.
  • Can one person run it, and what does a second seat cost?
  • What is free? Two of the eight send on a free plan; most of the rest offer a trial.

Software that writes and sends for you is a different category, and AI SDR tools that write and send for you has its own guide.

Prices read on each vendor's own page on 10 November 2026, in USD; the first price is the billing state the page opened with (GMass's default could not be determined). Mailboxes and domains are extra on most tools; see each section and the sending rules.

1. Instantly: unlimited mailboxes on one flat fee

Instantly pricing page, captured 10 November 2026, monthly billing
Instantly's Outreach plans on 10 November 2026, billed monthly. Yearly billing brings Growth to $37.60 a month.

Instantly pricing starts with Growth at $47 a month billed monthly, or $37.60 a month on yearly billing, as of November 2026. Growth includes unlimited email accounts, unlimited warmup, 1,000 uploaded contacts and 5,000 emails a month.

One subscription. Any number of sending accounts. The volume grows with the plan: Hypergrowth is $107 a month billed monthly for 125,000 emails and 25,000 contacts, and Light Speed is $358 a month for 500,000 emails, 100,000 contacts and the "SISR System", which assigns dedicated server and IP blocks and rotates them automatically.

Mailboxes and warmup are unlimited, and the leads database is a second bill.

Instantly's B2B leads database lives on a separate tab called Instantly Credits, with its own subscription. Growth Credits is $47 a month billed monthly ($37.60 yearly) for 1,500 to 2,000 Instantly Credits a month, and the Instantly Credits plans also list an AI email writer agent and a web researcher agent. If you want the data as well as the sender, budget for two plans.

You can sign up without a card. The page states no trial length and shows no free plan.

Pros

  • Unlimited email accounts and warmup from the cheapest plan

Cons

  • The leads database is a separate subscription
  • Growth holds only 1,000 uploaded contacts
Best for
Many mailboxes on one flat fee.
Pricing
Growth $47 a month billed monthly ($37.60 yearly), as of November 2026.
Verdict
The simplest bill if you plan to spread sending across many addresses.

2. Smartlead: four plans and automatic rotation

Smartlead pricing page, captured 10 November 2026, yearly billing
Smartlead's plans on 10 November 2026, yearly billing. Monthly billing is $39, $94, $174 and $379.

Smartlead counts two things, contacts stored and emails sent, and lets every plan connect as many mailboxes as you like. Its page opened on yearly billing, where Base is $32 a month ($39 billed monthly); yearly saves 17%. As of November 2026:

  • Base: $39 a month billed monthly, $32 on yearly billing, for 2,000 contacts and 6,000 email sends.
  • Pro: $94, or $78 yearly, for 30,000 contacts and 90,000 sends.
  • Unlimited Smart: $174, or $144 yearly, with unlimited contacts and 150,000 sends. Smartlead labels it the most popular plan.
  • Unlimited Prime: $379, or $315 yearly, with 500,000 sends and 3 SmartServers included.

Every plan connects unlimited mailboxes, and verified emails cost extra on the two cheaper ones.

The FAQ is plain about the core feature: "Smartlead automatically rotates sending across all connected mailboxes within a campaign." Every plan includes a warmup pool, with a better tier on the higher plans. The catch sits in the plan grid, where the verified-email allowance is a $59 a month add-on on Base and Pro and free on the two Unlimited plans.

The mailboxes themselves are sold separately. Smartlead's SmartSenders add-on sells fresh Google or Outlook mailboxes at $4.50 a mailbox a month plus $13 a domain a year, and other providers' mailboxes at $3.99 to $9. Agencies can add white-label client workspaces at $29 a month each, from Pro up. Every plan comes with a free trial that needs no card, and the FAQ says there are no lock-in contracts.

Pros

  • Automatic rotation across every connected mailbox
  • Monthly or annual plans with no lock-in

Cons

  • Verified emails cost $59 a month extra on Base and Pro
  • Mailboxes are a separate purchase
Best for
Multi-inbox senders and agencies.
Pricing
From $32 a month on yearly billing ($39 billed monthly), as of November 2026.
Verdict
Pick it when you run many mailboxes or several client accounts at once.

3. Woodpecker: a $39 plan with warm-ups counted in

Woodpecker pricing page, captured 10 November 2026, monthly billing
Woodpecker's plans on 10 November 2026, billed monthly, at 5,000 emails a month. Annual billing brings Email to $26 a month.

Woodpecker's Email plan is sized for a small team that sends a steady 5,000 emails a month. It costs $39 a month billed monthly, or $26 a month on annual billing, in USD as of November 2026. Only the default 5,000-email step of its volume slider was read, so do not assume $39 at any other volume.

Three warm-ups and unlimited teammates come in the $39 plan.

The Email plan lists these inclusions:

  • Unlimited contacts storage and unlimited email verification.
  • 3 warm-ups.
  • 100 Woodpecker Lead Finder credits.
  • Unlimited team members and unlimited email accounts, so a second person costs nothing extra.

Its deliverability list adds free warm-up, inbox rotation, adaptive sending and a domain audit that checks SPF and DKIM. Multichannel costs $68 a month billed monthly or $55 on annual billing, and it adds one LinkedIn account to the same 5,000 emails.

The free trial runs for 14 days or 500 cold emails, whichever limit you reach first, with no card. Past the emails-sent limit, Woodpecker's FAQ says, "the campaign won't send new emails to new prospects."

Pros

  • Warm-ups, verification and unlimited teammates in the $39 plan
  • A trial with a clear cap

Cons

  • Only three warm-ups on the Email plan
Best for
A small team on a fixed volume.
Pricing
Email $39 a month billed monthly or $26 on annual billing, at 5,000 emails; Multichannel $68 or $55, as of November 2026.
Verdict
Buy it for a steady, modest volume and a team that shares the work.

4. Saleshandy: leads and sending on one bill

Saleshandy pricing page, captured 10 November 2026, annual billing
Saleshandy's plans on 10 November 2026, billed annually. Monthly billing is $41, $99 and $189.

Saleshandy's Starter plan is $34 a month billed annually ($408 a year), or $41 if you pay monthly, as of November 2026. It covers 2,000 active prospects, which Saleshandy defines as "Contacts you can keep in live sequences at once", plus 6,000 emails a month and sender rotation across 10 email accounts.

Lead data comes in the box, but Starter is a single seat.

One user. Pro is $76 a month billed annually ($99 monthly) for 10 users, and Scale is $149 ($189 monthly) for unlimited users and 200,000 emails a month.

Every plan carries Saleshandy's lead finder credits: 1,500 a month on Starter, or all 18,000 upfront if billed annually. One Saleshandy credit reveals a verified email and six reveal a phone number, spent only when Saleshandy returns a verified result. Saleshandy's headline says you can warm up inboxes "with no metered credits"; its lead data is still metered in credits on every plan.

Mailboxes are unlimited on every plan, warmed "at no extra cost" and with no per-inbox fees. New ones cost $2.99 a mailbox a month on Saleshandy's annual fixed add-on, plus $14 a year per domain. The trial lasts 7 days and needs no card.

Pros

  • Lead data and sending on one bill
  • Unlimited mailboxes and warmup with no per-inbox fee

Cons

  • Starter has one user
  • Saleshandy's lead finder credits stop at 1,500 a month on Starter
Best for
A solo sender who wants leads in the same bill.
Pricing
Starter $34 a month billed annually ($41 monthly), as of November 2026.
Verdict
Good value for one person, until a second person needs a login.

The plan price leaves out the mailboxes. Take a hypothetical: three new mailboxes on one new domain, priced with the add-ons printed on 10 November 2026. Saleshandy's would cost $8.97 a month at its annual fixed rate, plus $14 a year for the domain. Smartlead's SmartSenders would cost $13.50 a month plus $13 a year for Google or Outlook mailboxes, and Hunter's start at $18 a month. Instantly and Woodpecker connect unlimited accounts, but the accounts still have to come from somewhere.

5. lemlist: priced by volume, with data on the side

lemlist pricing page, captured 10 November 2026, yearly billing
lemlist's plans on 10 November 2026, yearly billing. Monthly billing is $69 for Email and $109 a user for Multichannel.

On yearly billing, lemlist's Email plan is $55 a month, or $69 billed monthly, as of November 2026. That price is for the default volume of 50,000 emails a month; the other steps on its volume menu were not read.

The Email plan prices volume, not people, and data is an add-on.

Users and email senders are both unlimited on Email. The plan includes the lemwarm warm-up and a deliverability hub, an email and phone finder, CRM integrations and the API, plus lemAgent and lemlist's signal, enrichment and messaging AI agents. Its FAQ says lemwarm and the built-in deliverability protections "are included in all plans".

The finder runs on lemlist's credits, charged only for successful results. The data add-on is $16 a month on yearly billing ($20 monthly) for 2,000 lemlist credits a month, enough for 400 emails or 100 phone numbers, and unused credits roll over while your subscription stays active.

Multichannel is $87 a user a month on yearly billing ($109 monthly), with five senders per user, LinkedIn and SMS automation and a built-in call dialer. There is no free plan on lemlist's pricing page; the 14-day trial opens the Multichannel features except in-app calls and includes 200 free lemlist credits for finding emails and phone numbers. Start on Email if LinkedIn is a maybe, and move up when it becomes a yes.

Pros

  • Unlimited users and senders on the Email plan
  • Warm-up included in every plan

Cons

  • No free plan on the pricing page
  • Contact data costs $16 a month extra on yearly billing

6. Apollo: the contact database that also sends

Apollo pricing page, captured 10 November 2026, annual billing
Apollo's plans on 10 November 2026, billed annually per seat. Monthly billing is $65 and $99 a seat; on 11 November the monthly view marked Organization "Annual Only".

Apollo pricing, as of November 2026: Basic is $49 a seat a month billed annually, or $65 billed monthly. Every seat on an account sits on the same plan, and Organization needs at least three seats. Apollo marks the prices as "Introductory pricing" and notes that "features and pricing may change."

The contact data is the product, and sending stops at 250 a day on the two cheaper plans.

Apollo's plans and sending limits, read on its pricing page on 10 November 2026.

Organization$119 billed annually, minimum 3 seats (the monthly view shows $149 but marks it "Annual Only", 11 November 2026)Unlimited Google and Microsoft, plus 15 SMTPUnlimitedUnlimited, with A/Z testing

Apollo's credits pay for the data: 1 credit per email, 8 per phone number and 1 per AI research run. The Basic plan comes with 30,000 credits per seat a year upfront on annual billing, or 2,500 a month on monthly, and Apollo's unused credits expire at the end of each billing cycle. Its Basic and higher plans add a "Deliverability Suite & Email Warmup".

The Basic and Professional plans come with a 14-day trial. After it, Apollo says you can move to its free plan, which "stays free with no time limit".

Pros

  • The contact database and the sender in one login
  • A free plan that sends

Cons

  • One mailbox and 250 emails a day until Professional
  • Apollo's unused credits expire every billing cycle
Best for
Teams that need the data more than the sender.
Pricing
From $49 a seat a month billed annually ($65 monthly), as of November 2026.
Free tier
Yes: 2 sequences, 1 Gmail mailbox, 250 emails a day.
Verdict
Buy Apollo for the database, and pay for Professional only if it must also carry your volume.

7. Hunter: a free plan that can send

Hunter pricing page, captured 10 November 2026, yearly billing
Hunter's plans on 10 November 2026, paid yearly. Monthly billing is $49, $149 and $299; Free stays $0.

Hunter finds and verifies email addresses, and its outreach feature, Sequences, sends from the accounts you connect. As of November 2026, the Free plan is $0 with 50 Hunter credits a month, one connected email account and up to 500 recipients per sequence.

The free plan sends, and paid plans are sized by connected mailboxes.

  • Starter: $34 a month paid yearly ($408 a year), or $49 billed monthly, for 3 connected accounts and 2,500 recipients per sequence.
  • Growth: $104 a month paid yearly ($149 monthly) and 10 accounts.
  • Scale: $209 a month paid yearly, $299 monthly. It connects 20 accounts and allows 15,000 recipients per sequence.

Hunter's credits pay for Email Finder, Email Verifier and Domain Search. On monthly billing they reset each month and do not roll over, while yearly plans get the whole year's Hunter credits upfront. Users are unlimited on every plan, extra connected accounts cost from $10 a month each, and Hunter sells custom domains and email accounts from $6 a month per account. The pricing page names no warm-up feature.

Pros

  • A free plan that runs real sequences
  • Unlimited users on every plan

Cons

  • No warm-up feature named on the pricing page
  • Each sequence has a recipient cap
Best for
Finding and verifying emails, with light sending.
Pricing
Free; Starter $34 a month paid yearly ($49 monthly), as of November 2026.
Free tier
Yes: 1 connected account, 500 recipients per sequence, 50 Hunter credits a month.
Verdict
Start on Free if you send a little and need the addresses more than the volume.

8. GMass: cold email from the Gmail you already have

If you would rather not leave Gmail, GMass works inside it. It prices by country, and these are its US dollar prices for an individual as of November 2026. The default billing state for a US visitor could not be determined, so both states are below:

  • Standard: $29.95 a month billed monthly, or $249 a year. Mail merge with personalization and free address verification, but no sequences.
  • Premium: $39.95 billed monthly or $349 a year. This is where sequences and follow-ups start, along with A/B tests and the API.
  • Professional: $59.95 billed monthly or $599 a year, adding inbox rotation, which GMass calls MultiSend.

It sends from the Gmail you already have, so Gmail's limits are yours.

Standard promises "Send unlimited emails" with an asterisk. Read the asterisk: "Breaking limits depends on individual account configuration." Google Workspace caps a user at 2,000 messages a day, or 1,500 for mail merge, and after reaching a limit, "users can't send new messages for up to 24 hours."

The page has a "Try GMass for free" link but no free plan card and no trial terms. For one person sending from their own address, pick Premium if you want follow-ups; Standard sends each email once.

Pros

  • Nothing new to learn if you live in Gmail
  • The lowest paid monthly price of the eight

Cons

  • No sequences on Standard
  • Your account's own sending limits apply

9. Gravity: finds who to email and drafts it, but does not send at volume

The Gravity app: a prompt box asking what you want to get done
Gravity's home page in November 2026.

Gravity is my product, so weigh this section with that in mind. It is an AI agent platform: you type the task you need done, and it matches an expert-built agent that runs it. It does not send cold email at volume, which is why it sits last.

For AI cold email work, the November 2026 catalog has a Lead gen agent. Its description reads: "Finds companies that would buy what you sell, the right person at each (checked against their own profile), their email with how it was found, something real they recently did, and a first email in two versions."

It finds the people and drafts the first email, and it stops before volume sending.

  • It reads your Gmail and Google Calendar.
  • Hourly, it sees who replied and drafts answers and follow-ups.
  • It sends only what you approve, by email. LinkedIn and X messages are written for you to send yourself.
  • The leads come back as a CSV spreadsheet you can download.

What it leaves out matters more on this page. There is no mailbox warmup, no mailbox rotation and no high-volume sequences. If you already know who to email, one of the eight above is the tool you want; if you do not, start one step earlier.

Pros

  • The list, the research and a first draft from one task
  • Nothing is sent until you approve it

Cons

  • No warmup, rotation or volume sequences
  • Gravity is in public beta
Best for
The list and the first emails, before you send at volume.
Pricing
The Free plan is $0 with your first 3 agent runs free, and Mini Pilot is $15 a month, as of November 2026 (pricing).
Free tier
Yes: 3 agent runs, no card.
Verdict
Use it to find who to email and draft the first message, then send at volume from one of the eight.

Hand the Lead gen agent a task like "find 20 companies that would buy my bookkeeping service, the right person at each with their email and how it was found, and draft a first email in two versions for me to approve before anything is sent". It is not a bulk sender, with no warmup and no mailbox rotation, so pair it with a tool above if you send at volume. Gravity is in public beta, and your first 3 agent runs are free: Explore agents.

Snov.io, Reply.io and the free plans

Two more senders turn up on the ranking lists. Neither is numbered here, but both publish prices, read on 10 November 2026:

  • Snov.io: Starter is $39 a month billed monthly, or $29.25 a month on annual billing (the page's default), for 5,000 recipients, 3 email warm-ups and unlimited team seats. Its free Trial plan renews every month with 100 recipients, 50 Snov.io credits and one warm-up slot, and Snov.io says it is "not meant to help grow sales".
  • Reply.io: the Email Volume plan is $59 a user a month billed monthly, or $49 billed annually, with warmup included with every mailbox and a 14-day free trial. A Black Friday code was on the page when I read it, so check the price at checkout.

If you want to send without paying, three plans do it: Hunter Free, Apollo Free and Snov.io's Trial. None of the pricing pages I read offers a lifetime deal.

What Gmail, Yahoo and the law ask of a cold emailer

Cold email deliverability starts with rules the mailbox providers publish, and the law sits on top of them. Each item gives the source, its date and its status, as read on 10 November 2026. This page covers the US and the UK only.

  • Gmail (Google's Email sender guidelines; required since February 1, 2024). Every sender needs SPF or DKIM, valid forward and reverse DNS, a TLS connection and a spam rate below 0.3%; Google's best-practice target is below 0.10%. At close to 5,000 messages a day to personal Gmail accounts, you also need SPF and DKIM, DMARC (p=none is enough), an aligned From: domain, and one-click unsubscribe plus a visible link on marketing mail.
  • Gmail, scope and enforcement. Google's FAQ says the guidelines "don't apply to messages sent to Google Workspace accounts", and that "Starting November 2025, Gmail is ramping up its enforcement on non-compliant traffic," with temporary and permanent rejections. It recommends honoring unsubscribes within 48 hours.
  • Yahoo (Sender Requirements and Recommendations; enforced from February 2024). SPF or DKIM and a spam rate below 0.3% for everyone. Bulk senders also need both SPF and DKIM, a DMARC policy of at least p=none, one-click unsubscribe and a visible unsubscribe link, and Yahoo tells them to "Honor unsubscribes within 2 days".
  • US, CAN-SPAM (federal law; the FTC's compliance guide, edited January 2024). "The law makes no exception for business-to-business email." The guide asks for honest headers and subject lines, a message identified as an ad, your valid physical postal address and a clear opt-out honored within 10 business days, and it lists penalties of up to $53,088 per violating email. It lists no consent requirement before you send.
  • UK, PECR (ICO guidance; under review after the Data (Use and Access) Act). You do not need consent under PECR to email a company, but you must not hide who you are, and you must give a valid address to opt out. The ICO treats sole traders and some partnerships as individuals, whom you can email only if they have "specifically consented", and UK GDPR still applies to named business contacts.

This is not legal advice; check the law where your recipients are. Treat Google's rules as good practice for every inbox you send to anyway.

Which one should you choose?

Search for sales outreach tools and you get whole sales suites. For the sender alone, match the tool to your volume and to what you are missing. Prices are as of November 2026.

  • Many mailboxes on one flat fee: Instantly, from $47 a month billed monthly.
  • Rotation across mailboxes, or several client workspaces: Smartlead, from $39 a month billed monthly.
  • A fixed small volume with warm-ups and teammates included: Woodpecker.
  • One person who wants leads in the same bill: Saleshandy Starter, $34 a month billed annually.
  • A team that may add LinkedIn later: lemlist, starting on the Email plan.
  • The contact data matters more than the sender: Apollo. Below Professional, sending stops at 250 emails a day.
  • Mostly finding and verifying emails, sending a little: Hunter, starting on Free.
  • One person sending from Gmail: GMass, on Premium if you want follow-ups.
  • You do not yet know who to email: Gravity's Lead gen agent for the research and the first drafts, then one of the eight above for the volume.

The sender is one piece of outbound. AI agents for lead generation covers finding the people, and AI sales agents compared covers the rest of the sales funnel.

FAQ

1. What is the best cold email software?

It depends on what you need the plan to meter. As of November 2026, Smartlead starts at $39 a month billed monthly with automatic mailbox rotation, Instantly at $47 a month billed monthly with unlimited mailboxes and warmup, and Woodpecker at $39 a month billed monthly for 5,000 emails with three warm-ups, while Apollo suits a team that needs the contact data more than the sender.

2. Is there a free platform to send cold emails?

Yes, a few plans send for free as of November 2026. Hunter Free connects one email account with up to 500 recipients per sequence, Apollo Free sends 250 emails a day from one Gmail mailbox, and Snov.io's Trial plan renews monthly with 100 recipients and one warm-up slot. Smartlead, Woodpecker, Saleshandy and lemlist offer trials instead of free plans.

3. What is the cheapest cold email software?

On monthly billing as of November 2026, GMass Standard costs $29.95 but has no sequences, and Smartlead Base and Woodpecker Email (at 5,000 emails) cost $39 each. On yearly billing, Woodpecker falls to $26 a month and Smartlead to $32, and none of the pricing pages I read offers a lifetime deal. Budget for mailboxes and domains too: Saleshandy sells mailboxes from $2.99 a month plus $14 a year per domain.

4. Is cold email illegal?

Not in the US or the UK if you follow the rules, going by the FTC and ICO pages read on 10 November 2026. CAN-SPAM makes no exception for business-to-business email, requires a postal address and an opt-out honored within 10 business days, and the FTC lists penalties of up to $53,088 per violating email; under PECR you can email companies without consent if you say who you are and give an opt-out address, but sole traders count as individuals, and the ICO says its guidance is under review. This is not legal advice.

5. What is the 30/30/50 rule for cold emails?

It is a rule of thumb from vendor blogs, and they define it two ways. Tario says 30% personalization, 30% value and 50% follow-up, while Spotler says 30% targeting, 30% message and 50% follow-up and points out that the numbers add up to 110%. No study or original source for it could be found, so read it as a reminder to follow up.

6. Is cold email still effective in 2026?

It still works when the list is small and relevant and the mail meets the mailbox providers' rules. Since November 2025, Gmail has been ramping up enforcement on mail that misses its sender requirements, including temporary and permanent rejections, and Gmail and Yahoo both set a 0.3% spam-rate ceiling. Volume without relevance is what those rules punish.

7. Do I need to warm up a new mailbox?

Most of these tools assume you will. Instantly, Smartlead, Saleshandy, lemlist, Woodpecker, Snov.io, Reply.io and Apollo (from its Basic plan) include warmup in some form, while Hunter and GMass name no warm-up feature on their pricing pages. Warmup does not replace the sender rules: authentication and a spam rate under 0.3% still apply.
