The Best Free Email Marketing Tools in 2026 (We Tested 7)

There’s a difference between “free” and “useful.” Most “free email marketing” listicles include tools whose free tiers are designed to push you to paid within a week. We tested all the major free tiers across 30 days, on real workflows, to find the ones that genuinely work.

Quick verdict. Kit now has the most generous usable free tier: up to 10,000 subscribers, unlimited broadcasts, and paid newsletters, product sales and tip jars built in (but no automations). Beehiiv is the runner-up for newsletter operators: 2,500 subscribers and unlimited sends free, though paid subscriptions, the Ad Network and automations now start on its Lite plan ($49/month billed yearly, $59 monthly). Brevo wins if you hold a huge list but send rarely: up to 100,000 contacts, capped at 300 sends per day. MailerLite, our long-time default, cut its free tier to 250 subscribers and 2,500 sends in June 2026; it is now the pick for the cheapest upgrade path ($12/month Comfort, billed monthly) rather than for staying free. The rest are situational or restrictive.

This piece walks through what each free tier actually includes, what’s gated, and which ones you can run a real business on without upgrading for the first 6-12 months.

At a glance: what the free tiers actually offer

Tool	Subscriber cap	Send volume	Automations	Notable gating
Kit	10,000	Unlimited broadcasts	None on free	Automations, sequences and integrations paywalled
Beehiiv	2,500	Unlimited sends	None on free (Lite and up)	Paid subs, ad network and referrals on paid plans
MailerLite	250	2,500/mo	3 active (5 steps)	Free tier cut hard in June 2026
Brevo	100,000 contacts	300/day (~9,000/mo)	Limited	Daily send cap restrictive
Sender	2,500	15,000/mo	Limited	Smaller tool, less mature
MailJet	1,000 contacts	6,000/mo (200/day)	None	Daily cap; built for transactional
Mailchimp	250	500/mo (250/day)	Preview only	Most restrictive in this list

How we tested

Each free tier ran for 30 days against a real workflow — building a 200-subscriber list, sending one weekly broadcast, and running a 5-email welcome series.

What we measured: Setup time, deliverability (opens and inbox placement), feature accessibility on free, friction level of upsell prompts, and whether the free tier could actually run our test workflow end to end.

Real billing math: Modelled the upgrade cost when a typical small business grows past the free tier — 500 → 1,000 → 2,500 → 5,000 subscribers.

We re-test every 90 days. Last updated noted at the bottom.

1. Kit: the most generous free tier in the category

Kit (formerly ConvertKit) offers the largest subscriber cap on free, up to 10,000 subscribers, and it is no longer a stripped-down broadcast tool. The free Newsletter plan now includes tagging and segmentation, paid newsletters, digital product sales and tip jars. The one big gap: no automations or email sequences at all.

Best for. Creators and solo writers who want to build a big list and start earning from it (a paid newsletter, digital products, tips) before paying for software.

Skip Kit Free if. You need a welcome series or any automated sequence. There are none on free, so the 5-email welcome series from our test workflow can’t run there. Automations, sequences and app integrations start on the Creator plan.

What’s included on free.

• Up to 10,000 subscribers (yes, really)
• Unlimited email broadcasts
• Unlimited landing pages and forms
• Audience tagging and segmentation
• Paid newsletters, recurring subscriptions and tip jars
• Digital product sales
• Kit’s fee on sales: 3.5% + $0.30 per transaction, card processing included
• A/B tests on 2 subject lines
• Free Recommendations (swap recommendations with other Kit creators)
• Custom domain and custom HTML email templates

What’s gated to paid.

• Visual automations and email sequences (none at all on free)
• RSS campaigns
• 100+ app integrations and Kit MCP
• Removing Kit branding
• Free migration help
• Paid Recommendations and newsletter sponsorships

First paid step. Creator: $39/month billed monthly ($33/month billed yearly) for up to 1,000 subscribers, $89/month ($75 billed yearly) at 5,000. It adds unlimited automations and sequences, integrations and RSS campaigns, and removes Kit branding.

Where it wins. Up to 10,000 subscribers is enormous, and you can earn from day one: paid newsletters, product sales and tips all work on free, with tagging and segmentation included.

Where it loses. No automations at all, not even a welcome sequence, and no app integrations. And because Kit’s paid plans are priced by list size, the jump is steep if you need automations later: a 10,000-subscriber list goes straight to Creator at $139/month billed monthly ($116 billed yearly). We covered this in our Kit vs Beehiiv comparison.

2. Beehiiv: generous for growth, paid plans for monetization

• 2,500 subscribers
• Unlimited sends
• Website + newsletter pages (on a beehiiv domain)
• Recommendation Network and magic links
• One digital product (one-time purchase, 0% Beehiiv fee)
• A single welcome email
• Campaign analytics (30-day lookback)
• API and integrations

What’s gated to paid.

• Paid subscriptions (Lite and up; Beehiiv takes 0%, you pay Stripe fees only)
• Ad Network, programmatic ads and Boosts (Lite and up)
• Referral program, tip jar and coupons (Lite and up)
• Email automations: welcome series, drip campaigns (10 on Lite, unlimited on Pro)
• Custom domains, custom HTML and A/B testing (Lite and up)
• Advanced analytics (Lite and up)
• Multiple publications (3 on Lite, 10 on Pro)
• Removing Beehiiv branding (Pro)

First paid step. Lite: $59/month billed monthly ($49/month billed yearly) at 1,000 subscribers, $109/month ($95 billed yearly) at 5,000. It unlocks paid subscriptions, the Ad Network, the referral program and up to 10 automations.

Where it wins. 2,500 subscribers and unlimited sends on free, plus a website and the Recommendation Network to grow the list. When you do start earning, Beehiiv takes 0% of subscriptions and product sales (Stripe fees only). Built for the work newsletter operators actually do.

Same tutorial. The Products feature in action: name your product, write a description, set a price, watch the preview card update on the right. Free allows one product (Lite 3, Pro unlimited). Kit sells digital products natively too, on every plan including Free.

Same tutorial. What the buyer sees at checkout: a Stripe-powered page. Beehiiv takes 0% of product sales on every plan, so you pay only Stripe’s fees (2.9% + $0.30 per sale).

Where it loses. Paid subscriptions, ads, tips and automations all need a paid plan now (a real gap if you want a welcome series). Lite is also the priciest first paid step on this list. Less mature for non-newsletter use cases.

3. MailerLite: cut down on free, still the best cheap upgrade path

MailerLite was our default free recommendation for years, on numbers that no longer exist: 1,000 subscribers, 12,000 sends, unlimited automations. In June 2026 MailerLite restructured its plans and cut the free tier to 250 subscribers, 2,500 sends per month, and 3 active automations (5 steps each). Existing free accounts moved to the new limits on July 1, and free-plan feature limits start being enforced in mid-August 2026.

Frame from “Complete MailerLite Guide for New Users.” The free tier still looks like this, the same Subscribers UI as paid, but it is now capped at 250 contacts and 2,500 sends/month.

Best for. Starting on the platform you already know you will pay for. MailerLite’s real pitch is no longer the free tier, it is the $12/month Comfort plan sitting right above it, the cheapest serious paid plan in the category.

Skip the free tier if. You want to stay free for 6-12 months. At 250 subscribers, any list that is actually growing outgrows this in weeks. That job now belongs to Kit, Beehiiv or Brevo.

What’s included on free (post-June 2026).

• 250 subscribers, 2,500 sends/month
• 2 user seats (up from 1, the one limit that got better)
• 3 active automations, up to 5 steps each
• All three editors: drag-and-drop, custom HTML, and simple
• 1 website (with blog) + 1 landing page
• 3 active forms plus promotional pop-ups
• Sell 1 digital product
• Shopify and 100+ other integrations

What’s gated to paid.

• Removing MailerLite branding from emails and forms
• 50 automations, multivariate testing, AI writing assistant, smart sending, preference center (Comfort, from $12/month)
• Unlimited sends, automations, seats, and landing pages (Power, from $25/month)

Where it wins. Feature breadth. Even trimmed, the free plan includes a website builder, blog, pop-ups, and a custom HTML editor that most competitors gate. And the upgrade math is the best in the category: $12/month for Comfort, a few dollars above Brevo and Sender ($9) and well below Kit ($39) or Beehiiv ($59), all billed monthly.

Where it loses. The cap. 250 subscribers ties Mailchimp for the smallest allowance in this list, and the 2,500-send ceiling rules out any real cadence on a mid-size list.

For more context, see our Mailchimp alternatives review where MailerLite is still the overall winner, on paid value rather than free limits.

4. Brevo: the huge-list, low-send play

Brevo (formerly Sendinblue) is structured differently from every other free tier. Pricing scales by sends, not contacts. This means: up to 100,000 contacts on free, but capped at 300 sends per day (~9,000/month).

Best for. B2B businesses with huge contact lists but rare sends. Real estate agents with 5,000 client contacts who send a monthly newsletter. Medical practices, law firms, legacy B2B with bigger lists than send volume.

Skip Brevo if. You send weekly or more frequently to your full list — the 300/day cap will choke you fast. Or if you want the cleanest builder UI — Brevo’s UI is dated.

What’s included on free.

• Up to 100,000 contacts
• 300 emails/day
• Drag-and-drop builder
• Email customization
• Templates
• Mobile app
• Real-time reporting

What’s gated to paid.

• More than 300 sends/day
• A/B testing
• No Brevo branding
• Multi-user
• Advanced statistics
• Marketing automations
• Send-time optimization

Where it wins. The biggest contact allowance on free: up to 100,000. SMS bundled (paid). Strong CRM integration if you also use Brevo’s CRM.

Where it loses. 300/day cap is restrictive for active senders. UI feels older than competitors. Less polished than MailerLite or Beehiiv.

5. Sender: the underdog

Sender is the smaller, less-marketed alternative that punches above its weight. 2,500 subscribers free with 15,000 sends/month — meaningfully more than Mailchimp Free.

Best for. New bloggers, small businesses, anyone who specifically wants a paid-feature-rich free tier and doesn’t need name-brand recognition.

Skip Sender if. You need the deepest automations — Sender’s automation builder is more limited than MailerLite’s. You need multi-tool ecosystem (Sender’s standalone).

What’s included on free.

• 2,500 subscribers
• 15,000 sends/month
• Drag-and-drop builder
• Basic automations (welcome, etc.)
• Forms and popups
• Basic landing pages
• Email A/B testing (yes, on free)

What’s gated to paid.

• More automation triggers
• Push notifications
• Removing Sender branding
• API access
• Advanced segmentation
• SMS (paid add-on regardless of tier)

Where it wins. 2,500 contacts + 15,000 sends + A/B testing on free is uniquely generous. Cleaner UI than Brevo.

Where it loses. Smaller ecosystem, fewer integrations. Less name recognition (matters if your team is hiring marketing freelancers familiar with major platforms).

6. MailJet: fine for transactional, thin for marketing

MailJet is included for completeness but doesn’t earn a strong recommendation. Its free tier is roomier than Mailchimp’s (1,000 contacts, 6,000 emails a month), but the 200-a-day cap and thin marketing features hold it back.

Best for. Transactional email use cases (signup confirmations, order receipts) where 200 emails/day is sufficient. Not ideal for marketing email.

Skip MailJet Free if. You’re sending marketing email. Kit, Beehiiv, Sender and Brevo all give you more room on free, and MailerLite gives you better marketing tools. MailJet is more competitive on its paid plans for transactional email use cases.

What’s included on free.

• 1,000 contacts
• 6,000 emails/month (200/day cap)
• Email API access
• Basic templates

What’s gated to paid.

• More contacts
• Higher daily volume
• Marketing automation
• Most segmentation
• A/B testing
• Removing MailJet branding

Where it wins. Strong transactional email API on paid plans (a category most other tools in this list de-emphasize).

Where it loses. The 200-a-day cap means one send to a full 1,000-contact list takes five days. Marketing-focused features paywalled aggressively.

7. Mailchimp: once the default, now the most restrictive

Mailchimp is the platform with the most brand recognition. Its free tier is the smallest in this list (250 contacts, 500 emails a month), and the gating is aggressive.

Best for. Brand-new senders specifically wanting Mailchimp’s UI familiarity (often from previous use). Hobbyists with lists under 250 contacts.

Skip Mailchimp Free if. You want an actually useful free tier — every other platform in this list gives you more. Or if you’re comparison-shopping by feature parity.

What’s included on free.

• 250 contacts
• 500 emails/month (max 250 a day)
• Basic email builder
• Automation flows (preview only)
• Basic forms
• Mailchimp branding required on emails

What’s gated to paid.

• More than 250 contacts (forces upgrade fast)
• More than 500 emails/month
• A/B testing
• Multi-step automations
• Send time optimization
• Custom branding (no Mailchimp watermark)
• Integrations beyond basics

Where it wins. Brand recognition. Some specific integrations Mailchimp pioneered.

Where it loses. Most restrictive free tier in this list. Aggressive upsell prompts. Hasn’t kept pace on free-tier generosity since Intuit acquisition.

We covered why most users are leaving Mailchimp in our alternatives review.

Side-by-side: pricing when you outgrow free

Every tool above eventually says “upgrade.” What that actually costs (monthly billing, verified October 2026):

Tool	First paid tier	At 5,000 subscribers
Kit	$39/mo (Creator, up to 1,000 subs)	$89/mo
Beehiiv	$59/mo (Lite, up to 1,000 subs)	$109/mo
MailerLite	$12/mo (Comfort, 500 subs)	$49/mo
Brevo	$9/mo (Starter, 5,000 emails/mo)	n/a (see note)
Sender	$9/mo (Standard, 500 subs)	$39/mo
MailJet	$9/mo (Starter, 8,000 emails/mo, up to 2,000 contacts)	$19/mo (Essential, see note)
Mailchimp	$20/mo (Standard, 500 subs)	$100/mo

Brevo prices by emails sent, not contacts: Starter is $9/mo for 5,000 emails, $56 for 50,000 (billed monthly). MailJet also prices by emails sent, and its Starter plan stops at 2,000 contacts, so a 5,000-subscriber list needs Essential (unlimited contacts): $19/mo for 15,000 emails a month, billed monthly. On annual billing, Kit Creator is $33/mo and Beehiiv Lite $49/mo at 1,000 subscribers ($75 and $95 at 5,000). Some vendors run promotions; we quote list prices.

The pattern: Kit and Beehiiv give you the most on free but cost the most once you upgrade ($39 and $59 a month at 1,000 subscribers, billed monthly). If you just need clean email marketing, MailerLite’s $12 Comfort tier is the cheapest serious paid plan of the group. The full Kit and Beehiiv ladders are in our ConvertKit vs Beehiiv comparison, and the full cross-platform billing math is in our email marketing software guide.
