Here’s the thing nobody tells you when you’re first building your list: you do not need to pay for email marketing software when you’re just getting started.
Not $50/month. Not $30/month. Not even $10/month. There are genuinely solid free plans out there that will cover you until you’re well past 1,000 subscribers, and picking the wrong one early can cost you time migrating later.
The catch is that “free” means different things depending on who’s saying it. Some platforms call themselves free but limit you to 14 days. Some give you a free plan that’s so stripped down you can’t actually do anything useful without upgrading. And some are legitimately free with real features that let you run an actual email program.
This guide is only about that last category. Every tool on this list has a real free tier you can use indefinitely, not just a trial. And every one of them is specifically useful for founders, small business owners, and early-stage teams who are building their first list.
What You Actually Need at Under 1,000 Subscribers
Before getting into the tools, it’s worth being clear about what matters at this stage and what doesn’t.
At under 1,000 subscribers, you don’t need:
- Advanced predictive analytics
- Multi-touch attribution reporting
- Complex conditional logic across 10-step automation trees
- A dedicated IP address for sending
- Enterprise-grade CRM integration
At under 1,000 subscribers, you do need:
- A reliable way to collect email addresses (signup form or landing page)
- A welcome email or short welcome sequence that goes out automatically
- A simple way to send occasional campaigns to your whole list
- Basic analytics (opens, clicks, unsubscribes)
- Something you can actually figure out without a tutorial
That’s the bar. Everything else is nice to have but not necessary at this stage.
The Free Tier Landscape in 2026
A few things have shifted recently that are worth knowing before you pick a tool.
Mailchimp cut its free plan significantly in early 2026, dropping from 500 contacts to 250 contacts with 500 monthly sends. It used to be the obvious starting point for most people. It’s still usable for the very earliest days, but you’ll hit the ceiling fast if you’re actually trying to grow.
Brevo restructured its free plan around email volume rather than contact count, which is a fundamentally different approach than every other tool on this list. You can store unlimited contacts for free, but you’re limited to 300 emails per day. More on why this matters below.
Kit (formerly ConvertKit) raised its free plan limit to 10,000 subscribers, which is genuinely remarkable. But automation on the free plan is extremely limited, which undercuts a big part of what makes Kit worth using.
Sender quietly became one of the most generous free plans on the market: 2,500 subscribers and 15,000 emails per month, with automation included. Most people outside the email nerd community haven’t heard of it yet.
The Best Free Email Marketing Tools, Broken Down Honestly
MailerLite: Best overall free plan for most early-stage founders
Free plan: 1,000 subscribers, 12,000 emails per month
MailerLite is the tool that comes up most consistently in conversations among founders who’ve tried a few platforms and settled on something they actually like using. The interface is clean without being sparse. The drag-and-drop editor is genuinely good. And critically, the free plan includes automation, which most free tiers gut entirely.
What you get on free: the full drag-and-drop email builder, automation workflows, landing pages, signup forms and pop-ups, and basic analytics. The limitation is that MailerLite branding shows up in your email footer, you can’t use a custom HTML editor, and templates are locked behind the paid plan. None of that is a dealbreaker when you’re just starting out.
The paid plan starts at $10/month for up to 1,000 subscribers with unlimited sends, which is among the cheapest upgrade paths in the industry. At 5,000 subscribers you’re paying $32/month. That’s reasonable.
One thing worth knowing: MailerLite has a notoriously strict account approval process. When you sign up, they review your account and may ask what your business does and how you collected your subscribers. This is annoying if you’re in a rush, but it’s actually a feature masquerading as a bug. Because they keep their platform clean of spammers, their shared sending infrastructure has better deliverability than platforms that let anyone in. Your emails are more likely to land in the inbox.
Best for: Small businesses, newsletters, creators, and early-stage founders who want a clean tool that actually works without much setup.
Outgrow it when: You hit 1,000 subscribers or need advanced features like A/B testing and remove-branding options, at which point the $10/month paid plan is an easy upgrade.
Brevo: Best free plan if your list is growing fast but you send infrequently
Free plan: Unlimited contacts, 300 emails per day (~9,000/month)
Brevo’s free plan is structured entirely differently from everyone else, and it’s worth understanding why that matters.
Most email platforms charge based on how many contacts you store. This means your monthly bill goes up automatically as your list grows, even if you’re not sending more emails. If you add 500 subscribers this month, you pay more next month whether or not you send them anything.
Brevo charges based on emails sent, not contacts stored. The free plan lets you store as many contacts as you want, forever, for free. You just can’t send more than 300 emails per day (about 9,000 per month). For a startup that sends one weekly newsletter to a list that’s growing quickly but isn’t huge yet, this is the most founder-friendly pricing structure in the market.
The catch: 300 emails per day sounds like a lot until you actually think about it. If you have 1,000 subscribers and want to send a campaign to all of them at once, you’d need to send in batches over four days. That’s manageable but mildly annoying. If you have 500 subscribers and send once a week, you’ll never hit the limit.
Beyond the free plan, Brevo has added a lot of functionality in recent years. Full CRM features, SMS and WhatsApp marketing, transactional email (for things like order confirmations and password resets), and a deal pipeline. It’s become a more complete platform than its “email tool” reputation suggests.
One more thing: the paid plans are competitive. Starter at $25/month removes the daily send limit and Brevo branding. Business at $65/month adds A/B testing, advanced reporting, and a dedicated account manager at higher tiers.
Best for: Startups with growing lists who send low-to-moderate volume, and anyone who also needs basic CRM functionality in the same tool.
Outgrow it when: You need to send large campaigns to your whole list at once and the 300/day limit becomes operationally frustrating.
Sender: Most generous free plan limits in 2026
Free plan: 2,500 subscribers, 15,000 emails per month, automation included
Sender is the underdog on this list. Most founders haven’t heard of it, which is surprising given that it has arguably the most generous free tier available right now. 2,500 subscribers and 15,000 monthly sends at no cost, with automation and segmentation included.
To put that in context: Mailchimp‘s free plan gives you 250 contacts and 500 sends. Sender gives you 10 times more subscribers and 30 times more sends, for the same price (zero).
The tradeoff is that the platform is less polished than MailerLite and less full-featured than Brevo. The template library has about 60 options, most of which are decent but not exceptional. The drag-and-drop editor works but isn’t as intuitive as MailerLite’s. There’s no native landing page builder on the free plan.
But if your only constraint is budget and you want to maximize what you can do for free, Sender covers you for longer than almost anything else. Capterra reviewers give it a 4.7/5 across hundreds of reviews, with consistent praise for deliverability and support quality.
Paid plans start at around $15/month and hit $39.90/month at 10,000 subscribers with SMS features, whitelabeling, and up to three users included.
Best for: Very early-stage founders who need to maximize free tier limits and are comfortable with a less polished tool.
Outgrow it when: You want better templates, a landing page builder, or more advanced automation logic.
Kit (formerly ConvertKit): Best free plan for creators and newsletter operators
Free plan: Up to 10,000 subscribers, unlimited email sends, limited automation
Kit is the outlier here because of the sheer size of what they offer for free: 10,000 subscribers with unlimited sends. That’s legitimately remarkable and much more generous than anything else on this list at the subscriber level.
The catch is that Kit’s automation features are heavily limited on the free plan. You get one automation and one email sequence. That’s it. If you want to build multiple behavioral sequences, tag-based automations, or anything remotely complex, you need a paid plan. Paid starts at $15/month for up to 300 subscribers, which jumps to $49/month at 3,000 subscribers and $79/month at 5,000. Kit’s pricing isn’t cheap once you’re paying.
What Kit’s free plan is genuinely great for: building a newsletter or content-based audience, collecting subscribers through landing pages, and sending regular broadcast emails to your list. The platform is built specifically for creators (bloggers, podcasters, YouTubers, course creators, newsletter operators), and that focus shows in how well it handles the basics of audience-building.
The subscriber tagging system is intuitive. The landing page editor is solid. And you can actually sell digital products and paid subscriptions directly through Kit, which is unique and genuinely valuable if you’re monetizing an audience.
The free plan also requires you to display Kit’s recommended newsletters to your subscribers when they sign up. That’s a bit annoying because it means competitors can appear in your opt-in flow. You can turn this off on paid plans.
Best for: Newsletter operators, bloggers, podcasters, and anyone building an audience-first business where the free 10K subscriber limit is the headline feature.
Outgrow it when: You need real automation (more than one sequence), which means moving to a paid plan fairly quickly. If you’re a SaaS or ecommerce company, Kit probably isn’t the right fit regardless of price.
HubSpot: Best free plan if you also need CRM functionality
Free plan: 2,000 emails/month, 1,000 contacts (in the free CRM)
HubSpot’s free plan isn’t really an email marketing plan. It’s a free CRM that happens to include email marketing features. That distinction matters because it shapes how the tool is built and what it’s actually good at.
The free tier gives you contact storage for up to 1,000 people, 2,000 email sends per month, 20 landing pages, one sales pipeline, live chat, and Gmail/Outlook integration that automatically logs email conversations to contact records. For a B2B founder managing a combination of marketing emails and individual sales conversations, this is a remarkably complete free offering.
The email marketing features themselves are solid but not exceptional. One basic template, a functional drag-and-drop editor, and basic analytics. No A/B testing, limited automation, and HubSpot branding on your emails. For pure email marketing you’d want MailerLite or Sender instead.
But if you’re building a B2B business where you need to track individual deals alongside marketing campaigns, the HubSpot free CRM + email combo covers both reasonably well without paying anything. The real power is that everything is in one place: your prospects, your pipeline, your email campaigns, and your customer records all live together.
The paid marketing tiers start at $20/month for the Marketing Hub Starter, which adds email send limits up to 5x your contact tier, removes HubSpot branding, and adds some basic automation. The Professional tier at $890/month is where the platform gets genuinely powerful but that’s well beyond early-stage territory.
Best for: B2B founders who want CRM and email marketing in one free tool, and who are managing both individual sales conversations and list-based campaigns.
Outgrow it when: You need serious marketing automation capabilities, at which point the jump to HubSpot’s paid tiers is steep. At that point, combining HubSpot’s free CRM with ActiveCampaign for email automation is often a better value.
Mailchimp: Fine for absolute beginners, quickly limited
Free plan: 500 contacts, 1,000 sends per month
Mailchimp used to be the default recommendation for anyone just starting out. The free plan was genuinely generous, the brand recognition meant abundant tutorials and third-party integrations, and the interface was familiar enough that even non-technical founders could get going quickly.
Then they cut the free plan. Hard. In recent years, the contact limit dropped from 2,000 to 500, and sends dropped to 1,000/month. By early 2026, unsubscribed contacts still count toward your billing cap unless you manually archive them, which is a gotcha that surprises a lot of people when they try to figure out why they’re being billed for contacts who aren’t even on their list anymore.
At 500 contacts, you’ll hit the ceiling within a few months of actively building your list. And the free plan only includes single-step automations, meaning you can set up a welcome email but not a multi-email welcome sequence. For that you need the Essentials plan at $13/month.
Mailchimp is still a fine tool. The brand is recognized everywhere, integrations are plentiful, and the editor is solid. But for founders starting fresh in 2026, MailerLite or Brevo offer more value at the zero-dollar tier by a significant margin.
Best for: People who specifically want Mailchimp for its brand recognition or existing integrations, and are okay upgrading quickly.
Outgrow it when: Pretty much immediately if you’re actively growing your list, at which point the $13/month Essentials plan is the minimum viable paid tier.
GetResponse: Solid free plan with a webinar twist
Free plan: 500 contacts, unlimited monthly emails, one landing page
GetResponse doesn’t get talked about as much as the others on this list, but the free plan is worth knowing about. Unlimited monthly emails to 500 contacts is a strong ratio, and they include a landing page builder and basic automation on the free tier.
What makes GetResponse interesting, even at this level, is the webinar functionality that shows up in paid plans. If you’re running a business where live events, demos, or educational webinars are part of your sales motion, GetResponse is one of the only platforms in this price range that handles email marketing and webinar hosting natively. The webinar attendee cap starts at 100 on lower paid tiers.
The editor was recently redesigned and is clean and functional. The automation builder is visual and genuinely easier to learn than some competitors. The template library has hundreds of options.
Paid plans start at $19/month for the Starter tier (1,000 contacts), which is competitive. The Marketer plan at $59/month unlocks the full automation capabilities.
Best for: Founders who send content-heavy newsletters and also run live events, demos, or webinars as part of their marketing.
Outgrow it when: You hit 500 contacts or need more than one landing page and basic automation.
How to Actually Choose Between These
The “which one is best” question doesn’t have a universal answer. It depends on your specific situation. Here’s a quick decision framework:
You’re a B2C or ecommerce founder with a growing list: Go with Brevo. The unlimited contacts on the free plan means you won’t hit a ceiling for a long time, and the multi-channel capabilities (email + SMS) give you room to expand without switching tools.
You’re a newsletter operator or content creator: Kit is the obvious choice if you want to stay free as long as possible. The 10,000 subscriber free plan is unmatched. Just know that real automation requires upgrading.
You want the best balance of free features and upgrade path: MailerLite is the safest pick for most early-stage founders. The editor is excellent, automation is included, landing pages are included, and the $10/month paid plan is a painless upgrade when you’re ready.
You want maximum free limits without caring about polish: Sender is worth trying. 2,500 subscribers and 15,000 sends for nothing is genuinely the most generous free tier on the market in terms of raw capacity.
You’re B2B and need CRM + email in one place: HubSpot‘s free plan is the move. Don’t think of it as an email tool with CRM features. Think of it as a free CRM that happens to let you send email campaigns.
You want name recognition and don’t mind hitting limits quickly: Mailchimp is fine. Just know you’ll be upgrading faster than you expect.
Things to Watch Out For When Signing Up for Free Plans
A few things trip people up that are worth knowing in advance.
Hidden contact counting. Some platforms count unsubscribed contacts against your plan limit. Mailchimp is the main offender. If you have 400 active subscribers and 200 unsubscribes, some plans still count all 600 against your limit. Read the fine print before you hit a surprise billing wall.
Automation gating. The most common way free plans limit you isn’t subscriber count, it’s features. Most platforms give you basic single-step automation on free tiers and require an upgrade for multi-step sequences. If automations are important to you from day one, MailerLite, Brevo, and Sender are the three options that don’t gut automation on the free tier.
Branding in your emails. Every free plan except HubSpot adds the platform’s branding to your email footer. “Powered by MailerLite” or “Sent with Brevo.” For most early-stage businesses this is fine. If you need clean unbranded emails, that’s a paid feature on every platform.
Deliverability on day one. When you first create an account, your sender reputation is essentially zero. Most platforms put new accounts through a brief review or warm-up period. MailerLite‘s account approval process is the most thorough but leads to better deliverability outcomes. Don’t be surprised if your first few campaigns have slightly lower delivery rates than the benchmarks you read about online.
The migration tax. Every platform makes it easy to import your list. What’s harder is rebuilding your automations, recreating your templates, and moving your signup forms if you decide to switch tools later. Pick something you can see yourself staying with for at least 12-18 months.
What Happens When You Actually Need to Pay
Most founders hit the ceiling on free plans somewhere between three and nine months after getting serious about building their list. Here’s what the upgrade path looks like for the top picks:
- MailerLite: $10/month for 1,000 subscribers unlimited sends. $19/month at 2,500. $32/month at 5,000. Very predictable.
- Brevo: $25/month removes the daily send limit and adds more features. $65/month for the Business plan with A/B testing and advanced reporting.
- Kit: $15/month for up to 300 subscribers. $49/month at 3,000. $79/month at 5,000. Gets expensive faster than the others.
- Sender: $15/month for up to 2,500 subscribers. $39.90/month at 10,000. Competitive throughout.
- HubSpot: $20/month for Marketing Hub Starter. Jumps hard at higher tiers.
- Mailchimp: $13/month for Essentials (500 contacts). $20/month for Standard. $350/month for Premium at 10,000 contacts, which is not competitive.
The honest answer: if you’re past 1,000 subscribers and using email strategically, paying $10-25/month is a genuinely good business investment. The ROI math on email is so strong that almost any paid plan pays for itself quickly once your list is actively converting.
A Note on What NOT to Do
A few things founders do with email that cause more damage than starting with the wrong free tool:
Using Gmail BCC to send to your list. If you’re emailing 100 people by putting them all in BCC, stop immediately. Gmail will flag your account, you have no way to track results, there’s no opt-out mechanism (which is legally required), and you’re building nothing durable. Any of the free tools above is better than this.
Buying an email list. This deserves repeating because people still do it. Buying a list of “10,000 targeted leads” and blasting them is spam. It will crater your sender reputation, get your account suspended on any reputable platform, and generate basically no revenue. Build your list organically.
Waiting until you have a “real” list to start. The best time to get your email setup in place was before your first subscriber. The second best time is right now. Set up your welcome sequence, get your signup form live, and start building the habit of sending. Even a list of 50 people is worth nurturing correctly from the beginning.
The Bottom Line
For most founders building their first email list in 2026, the right starting point is MailerLite or Brevo. MailerLite if you want the cleanest tool with the best editor and a reliable upgrade path. Brevo if your list is growing fast and you want to avoid contact-based pricing for as long as possible.
If you’re a creator or newsletter operator, Kit’s free tier up to 10,000 subscribers is hard to beat on paper, just know that real automation requires paying.
If you’re B2B and also running a sales pipeline, HubSpot’s free plan covers both in a way nothing else does for free.
The tool matters less than using it consistently. Pick one, get your welcome sequence in place, start collecting emails, and send something worth reading. The platform you start on can always be changed later. The list you build stays with you.
