On This Page
Free email marketing tools have polarized: some free plans behave like extended trials, while others can support a real early-stage workflow. This guide was refreshed with vendor pricing-page research on May 24, 2026, and uses plan-model language instead of brittle free-tier numbers.
How we picked them
We filtered for tools that offer a permanent free plan rather than only a short trial, include automation or workflow features on the free path, and have at least basic Shopify or ecommerce integration. We verified plan limits directly on each vendor’s pricing page in 2026.

How to choose
Use these three filters:
- List size vs. send frequency. Big list, infrequent sends? Brevo wins on price. Small list, daily newsletter? Kit or MailerLite.
- Ecommerce or content? Brevo, Sender, and Omnisend have purpose-built Shopify integration. Kit and HubSpot are content-first.
- Where does your CRM live? HubSpot Email Marketing makes sense if you are already on HubSpot CRM. Brevo includes a free CRM in the same workspace, which removes the integration question entirely.

Frequently Asked Questions
What is the best free email marketing tool in 2026?
Compare Brevo for volume-based sending plus CRM, Kit for creators, MailerLite for simple newsletters and landing pages, Sender and Omnisend for ecommerce, HubSpot for CRM-led marketing, and Mailchimp for brand familiarity.
Is Mailchimp still free?
Mailchimp has a free entry path, but verify current contacts, sends, audiences, branding, support, and automation limits because free-plan terms change often.
What happened to ConvertKit?
ConvertKit rebranded to Kit. Verify current subscriber, broadcast, landing-page, commerce, automation, and creator-network limits on Kit's pricing page.
Which free email tool is best for ecommerce?
Brevo, MailerLite, Sender, and Omnisend are common ecommerce candidates. Compare Shopify integration, segmentation, cart workflows, send limits, SMS, and contact pricing before choosing.
What is the catch with free email tools?
Common limits in 2026: branded footer, slower sending speed, no premium templates, no advanced segmentation, no A/B testing, and tighter contact caps. Read the free plan page on the vendor's site before you import a list.
Is Brevo really free?
Brevo has a free entry path. Verify current daily/monthly sends, branding, automation, CRM, landing page, multi-user, SMS, and transactional-email limits before planning production workflows.
Can I send transactional email on a free plan?
Brevo, Sender, and Mailchimp Transactional (Mandrill) all support transactional email, but only Brevo includes it on the marketing free plan. Most other tools route transactional through a separate paid product.
How do I migrate from Mailchimp?
Export your audience as CSV, export campaigns and templates if you want history, then import into the new tool. Most platforms (Brevo, Kit, MailerLite) have a Mailchimp-specific migration wizard that handles the field mapping for you.
