Most "best free cold email tools" lists are a bait-and-switch. We pulled the nine tools with genuine free forever plans and compared the features, sending limits, and trade-offs of each.
You click into "best free cold email tools" expecting free, you scroll, and every tool turns out to be a 14-day trial that auto-charges your card on day 15. That's not free. That's a free sample at Costco.
We went through every cold email platform we could find and pulled the ones with actual free forever plans. No credit card, no countdown timer, no "free for 7 days and then we email you 40 times begging you to upgrade." Nine made the cut.
A few tools you'd expect to see on a list like this didn't make it, and we'll explain why at the bottom. Spoiler: Instantly, Smartlead, Saleshandy, Lemlist, GMass, Woodpecker, and Mailshake all sound free in their marketing. None of them actually are.
AutoMailer is the only free plan with unlimited email accounts, unlimited sends, and built-in warmup. Apollo wins if you mostly need a prospecting database and light Gmail outreach. Snov.io is the best free plan with a warmup slot bundled in. Mailmeteor is the cleanest Gmail mail merge. Hunter Campaigns is the best free plan if you already use Hunter to find emails.
Once you stop counting trials as free plans, the field shrinks fast. Here's the side-by-side on the nine tools that survived our filter.
| Tool | Free sending limit | Email accounts | Warmup? | Sequences? | Rating |
|---|---|---|---|---|---|
| AutoMailer | Unlimited sends | Unlimited | Yes | Yes | |
| Apollo | 10,000/mo (verified corp domain) | Gmail only | No | 2 active | |
| Snov.io | ~100 recipients/mo | 1 sender | 1 slot | Yes | |
| Hunter Campaigns | 500 recipients per campaign | 1 sender | No | Basic | |
| Mailmeteor | 50 emails/day | 1 Gmail | No | Basic | |
| YAMM | 20 recipients/day | 1 Gmail | No | No | |
| Yesware | 10 recipients/mo | 1 sender | No | Limited | |
| Streak | 50 mail merges/day | 1 Gmail | No | No | |
| Mixmax | Tracking + scheduling, no real sequences | 1 sender | No | Limited |
Notice the pattern? Once you get past AutoMailer, the free plans drop fast. Most of them are tracking pixels and mail merge tools dressed up as cold email tools. That's not us being dramatic. That's literally what they are.
Let's get into the reviews.
Best for: anyone who wants a full cold email platform that's actually free, not a trial in disguise.
We're AutoMailer, so yes, we put ourselves first. But here's the test we held everyone on this list to: does the free plan let you run real cold email campaigns, or is it a glorified preview?
AutoMailer's free plan is the only one in this guide that passes. You get 5,000 contacts, unlimited email accounts, unlimited sends, free email warmup for Google Workspace and Microsoft 365, 100 lead finder credits per month, a spam word checker, inbox rotation, A/B testing, DNS authentication checker, and 1 workspace. No credit card. No 7-day timer.
DFY mailboxes are $3.50/mo each, custom domains $15/year.
If you're testing whether cold email even works for your business before paying anyone, AutoMailer is the only option in this guide that lets you do it properly. Real warmup. Real inbox rotation. Real sending. We built it this way on purpose. The cold email category has been pretending "$37/month" is the floor for too long. It isn't.
Unlimited accounts, unlimited sends, free warmup. No credit card required.
Get StartedBest for: light prospecting and outreach from Gmail when you don't yet need warmup.
Apollo is one of the few tools on this list with a genuinely usable free plan, mostly because their database is the actual product they want you to upgrade for. The free plan gets you access to their 275M+ contact database, 10,000 emails/month on a verified corporate domain, and 2 active sequences.
Apollo's free plan is real, but it's a Gmail-only experience designed to get you hooked on the database before you outgrow the 2-sequence cap. Great for testing. Limited for actually scaling. If data accuracy matters for your campaigns, layer in a verification tool before sending. Apollo's biggest weakness is the addresses it surfaces, not the platform itself.
Best for: free plan with a warmup slot included. A rare combo for cold email.
Snov.io takes a different approach than most tools on this list. The free plan bundles email finding, verification, sending, and one warmup slot into a single workflow. You won't run high-volume outreach on it, but you can build a small list, verify it, send it, and warm up one inbox without spending a dollar.
Snov.io's free plan is the most "all-in-one" of any free tier on this list. Finding, verifying, sending, and 1 warmup slot in one place. That's a real differentiator. The catch is the UI complexity and the credits-expire-monthly model that feels designed to push you off free quickly.
Best for: people who already use Hunter to find emails and want to send from the same tool.
Hunter made its name as an email finder, and Hunter Campaigns is the cold outreach layer they bolted on top. The free plan gives you 25 searches and 50 verifications per month, plus the ability to run campaigns to up to 500 recipients.
If your cold email strategy is "find 20 great prospects per month and send them a thoughtful message," Hunter's free plan is enough. If you want to scale beyond that, you'll need either a real warmup tool or a real sequencer. Hunter doesn't pretend to be either.
Best for: solopreneurs doing mail merge from Gmail and Google Sheets.
Mailmeteor is a Gmail and Google Sheets-native mail merge tool. The free plan lets you send up to 50 personalized emails per day, forever. No credit card, no trial timer. It's recommended by Google in their Workspace Marketplace, which is genuine social proof.
Mailmeteor is the cleanest "I just want to send 30 personalized emails per day from Gmail" tool on this list. It does that job well. The moment you want warmup, rotation, or anything resembling a real cold email infrastructure, you've outgrown it.
Best for: absolute beginners testing mail merge with Gmail.
YAMM is one of the oldest mail merge tools for Gmail. The free plan caps you at 20 recipients per day, which is honestly more of a "try the tool" experience than a working free plan. But it exists, it doesn't expire, and it has ISO 27001 certification, which matters for some teams.
YAMM is the "if I'm going to spend $25 once and never think about it again" option. The free plan is too capped to do real work on, but if you outgrow Gmail's free quota and don't want a recurring subscription, YAMM's $25/year Personal plan is one of the cheapest mail merge tools on the market.
Best for: sales reps doing low-volume tracking and templated outreach from Gmail or Outlook.
Yesware has been around since 2010 and was acquired by Vendasta in 2022. It lives inside Gmail and Outlook as an extension. The free plan is mostly an email tracking layer. You get unlimited email tracking, basic templates, and 10 recipients per month for campaigns.
Yesware's free plan is for tracking emails you'd send anyway, not for running cold email campaigns. If you're an AE who wants to know when prospects open your one-to-one emails, it's fine. For actual cold outreach, it's not the tool.
Best for: free Gmail-based CRM and mail merge for solo founders.
Streak is technically a CRM that lives inside Gmail, but the free tier includes mail merge up to 50 emails per day, plus unlimited email tracking and snippets. As far as Gmail-native free tools go, it's one of the more generous tracking offerings.
Streak's free tier is the strongest "Gmail tracking + light mail merge" offering on this list. If you're a solo founder sending under 50 personalized emails a day from your real Gmail address, it's a good fit. For actual cold email at any scale, the lack of warmup is a hard ceiling.
Best for: Gmail users who want tracking, meeting scheduling, and basic sequences in one tool.
Mixmax starts users on a 14-day trial of paid features, then drops you to a free tier with email tracking, meeting scheduling, and basic sequence functionality. The free plan isn't generous, but it doesn't disappear and it doesn't force you to enter a credit card upfront.
Mixmax is closer to a productivity layer for sales reps than a cold email tool. The free plan is fine if you want meeting scheduling and tracking inside Gmail, but it isn't built for cold outreach at any meaningful volume.
We're going to name names. These are the tools that show up in every "best free cold email tools" list, and none of them have actual free plans.
If "free" matters to you, the lineup above is the actual list. Everything else in this category wants your credit card before you've sent your first email.
Once you stop counting trials as free plans, the field gets clearer. Here's how we'd think about picking one.
Lemlist's "free plan" can't send a single email. Yesware's caps you at 10/month. Streak limits you to 50/day inside Gmail. The first real question isn't "is it free." It's "can I send a campaign with this?"
If the answer is no, it's not a cold email tool. It's a tracking tool or an email finder with cold email branding.
This is the biggest differentiator on free plans right now. Cold email without warmup in 2026 is a fast path to the spam folder, especially with Google and Microsoft's tightened sender requirements.
Of the nine tools on this list, only AutoMailer and Snov.io include warmup on their free plans. Everyone else either doesn't offer warmup at all or gates it behind a paid tier.
If you're running cold email at any real volume, you'll want to rotate sends across multiple inboxes to protect deliverability. Most free plans only let you connect 1 account.
AutoMailer's free plan is the only one that includes unlimited email accounts. That's not a marketing flex. It's a structural difference. Everyone else built their free plan to push you to upgrade the moment you connect a second mailbox.
The honest question isn't "is the free tier good." It's "what happens when I outgrow it?" A free plan that funnels you into a $79/user/month upgrade is different from one that scales to $29/month flat.
Run the math at 5 users and at 20 users before you pick a tool. Per-seat pricing punishes growing teams. Flat pricing doesn't.
Some free plans cap contacts (Yesware's 10/month). Some cap sends per day (Mailmeteor's 50/day, YAMM's 20/day). Some cap features (no warmup, no rotation, no A/B testing).
There's no single right answer. It depends on what you're testing. But know the cap before you start, not after you hit it mid-campaign.
We didn't rank by who paid us (nobody did) or who has the biggest brand. We ranked by what the free plan actually does.
What we scored:
That last criterion is why this list is 9 tools long and not 20. Most of what gets called "free" in this category isn't.
Yes, but fewer than the internet would have you believe. The tools with real free forever plans are AutoMailer, Apollo, Snov.io, Hunter Campaigns, Mailmeteor, YAMM, Yesware, Streak, and Mixmax. Most other "free" cold email tools are actually 7-day or 14-day trials that require a credit card and auto-charge at the end.
A free plan doesn't expire and doesn't require a credit card. A free trial gives you full access for a set window (usually 7 or 14 days), then either downgrades you or charges your card. Cold email tools love to blur this line in their marketing.
It depends on the tool. AutoMailer's free plan lets you run unlimited campaigns with unlimited accounts and built-in warmup, so yes. Mailmeteor's free plan caps you at 50 emails/day, which works for low-volume founders. Yesware's free plan caps you at 10 recipients/month, which doesn't. The honest answer: AutoMailer is the only free plan in this guide built for real cold email campaigns. The rest are either mail merge tools, tracking tools, or test environments.
AutoMailer. Free plan includes unlimited sends across unlimited email accounts. Every other free plan in this guide caps you somewhere, either at a daily send limit, a monthly recipient limit, or a single connected mailbox.
Yes. Unlimited warmup for Google Workspace and Microsoft 365 mailboxes is included on the free plan. We don't gate warmup behind a paid tier because cold email without warmup doesn't really work.
For light prospecting and outreach from a single Gmail account, yes. For multi-inbox campaigns, custom domain sending, or anything requiring warmup, no. Apollo's free plan is really a database trial dressed up as a free cold email tool.
If you want a Gmail-native experience, Mailmeteor or Streak are the cleanest options on free. Both work inside Gmail without a separate dashboard. If you want a real cold email platform that also connects Gmail accounts, AutoMailer's free plan does that and includes warmup.
Only on AutoMailer. Every other free plan in this guide limits you to 1 sending account. Most of them push multi-account connections to their highest paid tier.
Technically yes, functionally no. Lemlist's free plan is a Chrome extension that lets you find up to 100 leads' emails per month. You cannot send a single cold email from it. To actually use Lemlist as a cold email tool, you need to pay $63/user/mo or more.
No. GMass has a 7-day free trial that caps you at 50 emails per day during the trial. After 7 days, you pay $29.95/mo minimum. The "50 emails/day forever" free tier that GMass used to offer was discontinued in 2016.
It depends on the tool. AutoMailer's Starter plan is $29/mo and bumps you to 15,000 contacts with the same unlimited accounts and warmup. Apollo's Basic is $49/user/mo and scales linearly with team size. Lemlist's entry tier is $63/user/mo. Run the math at your expected team size before you commit. Per-seat pricing models get painful fast.
Start free if you're testing whether cold email works for your business at all. Pay when you've validated the channel and need volume, warmup at scale, or team features. Don't pay $79/month to find out cold email doesn't fit your business. Use a free plan to figure that out first, then upgrade once you know.
If you've made it this far, you already know our pitch. AutoMailer's free plan is the only one in this guide built for real cold email: unlimited accounts, unlimited sends, free warmup, and the deliverability tools you'd otherwise pay $50 to $200/month for. No credit card. No 7-day timer.
