Best Free Email Marketing Tools
Every tool on this list has a free tier you can actually run a list on, not a seven-day trial dressed up as one. We checked current contact and send limits ourselves, since these numbers get quietly trimmed, and noted where you will hit a wall on automation, branding removal, or list size.
- 1
HubSpot's free CRM includes email marketing with campaign building, tracking, and no paid plan required.
- 2
Formerly Sendinblue before its 2023 rename, Brevo runs one of the most generous free tiers in email marketing by storage, with room for up to 100,000 contacts even on the free plan, though sending is capped daily rather than monthly. SMS, WhatsApp, and a basic CRM ship in the same account as the email tool.
- 3
Klaviyo's free tier supports 250 contacts and 500 monthly sends, with Shopify and WooCommerce built in.
- 4
Zoho Campaigns provides 2,000 subscribers and 12,000 monthly emails free, integrated with Zoho CRM tools.
- 5
Permanent free tier with no limits on contacts or emails; takes 10 percent of subscription revenue above $50k annually
- 6
Mailchimp's free plan serves up to 500 contacts with 1,000 monthly sends, automation, and templates.

- 10
Email marketing platform with integrated event marketing and CRM tools, offering a free plan for up to 250 contacts and 5,000 emails monthly.
- 11
A Lithuanian platform whose free-forever plan covers 2,500 subscribers and 15,000 emails a month, more headroom than most free tiers on this list, with automation and segmentation included rather than locked to paid plans. The trade-off is a smaller template library and less name recognition than the bigger players.
- 12
SendPulse's free email plan covers 500 subscribers and 15,000 monthly sends, bundled with SMS tools.
- 13
All-in-one platform with free tier for 500 contacts and 2,500 emails per month; includes landing pages and automation
- 14
Email service provider delivering 6000 free emails monthly for transactional and marketing use
- 15
Transactional email service with 100 free emails per month; developer-focused with strong deliverability
- 16
A French all-in-one platform bundling email marketing with sales funnels, a course builder, and a blog, aimed squarely at solo creators and course sellers who'd otherwise juggle four separate subscriptions. The free plan is unusually complete rather than a stripped demo of the paid product.
- 17
Modern email API for developers with React component support and 3000 emails per month on the free tier
- 18
Omnisend's free plan covers 250 contacts and 500 emails monthly, designed for ecommerce stores with SMS.
- 19
Email API for developers with free tier offering 100 emails daily for transactional and marketing campaigns
- 20
AWeber's free plan covers 500 subscribers with landing pages, autoresponders, and foundational features.
- 21
A WordPress plugin, now owned by Automattic through its WooCommerce acquisition, that sends newsletters and WooCommerce order emails straight from your site's dashboard instead of a separate app. It only makes sense if your site already runs on WordPress, but for that audience it removes an entire external tool.
- 22
Email marketing platform with free tier providing 100 emails daily via API and SMTP
- 23
Self-hosted publishing platform with free email newsletters and no cut on subscriber earnings
- 24
Email delivery platform focused on testing with 4000 free emails monthly for transactional needs

- 26

- 27
Free tier offers 2,500 subscribers and 10,000 emails per month with newsletter templates included
- 28
Email marketing platform with automation and behavioral triggers included on the free tier
- 29
A transactional email API from the team behind MailerLite, built for developers sending password resets, receipts, and notifications rather than marketing newsletters, with SMTP relay, webhooks, and inbound routing available even on the free tier. It's a narrower tool than most on this list, and that's the point.
- 30
Email marketing service offering a free tier for up to 500 subscribers, with responsive templates and basic automation included.
- 31
Open-source email marketing with campaign management and advanced list segmentation
- 32
