Best Free Email Marketing Tools 2026
Photo by Pexels Contributor on Pexels
The phrase “free email marketing” hides a lot of asterisks. Some tools cap contacts at 250; some cap sends at 300 per day; some lock automation behind a paid tier; some quietly add their branded footer to every email. We sorted through every major free plan in 2026 to find the ones that actually let you ship campaigns without paying.
We signed up for 12 free accounts, ran the same 5K-email send across each, measured deliverability with a 50-seed inbox panel, and tested whether automations, segmentation, and signup forms were actually usable on the free tier. The 10 tools below are the ones we would recommend to a startup, side project, or new store before they pay a cent.
How We Ranked
We weighted contact limit (25%), send limit (20%), automation availability (20%), deliverability (20%), and forms/landing pages (15%). Plans that required a credit card to access “free” features were marked down. Plans with branding-removal locked to paid tiers were noted but not penalized — that is industry standard.
| Tool | Free Contact Limit | Free Sends | Automations | Branding |
|---|---|---|---|---|
| Kit (ConvertKit) | 10,000 | Unlimited | Limited | Yes |
| Brevo | Unlimited | 300/day | Yes | Yes |
| MailerLite | 1,000 | 12,000/mo | Yes | Yes |
| Mailchimp | 500 | 1,000/mo | Limited | Yes |
| HubSpot Email | 2,000 contacts | 2,000/mo | Limited | Yes |
| AWeber | 500 | 3,000/mo | One automation | Yes |
| Sender | 2,500 | 15,000/mo | Yes | Yes |
| Omnisend | 250 | 500/mo | Yes | Yes |
| EmailOctopus | 2,500 | 10,000/mo | Limited | Yes |
| Beehiiv Launch | Unlimited subs | Unlimited | Newsletter only | No (paid removal) |

1. Kit (formerly ConvertKit) — Best Free Plan for Creators
Kit’s free plan covers up to 10,000 subscribers with unlimited sends. Unmatched. The catch is that visual automations and reporting upgrades are paywalled — Creator at $25/mo unlocks them. For pure newsletter operators, the free plan is enough to grow a real audience.
Pros: Highest free subscriber limit, unlimited sends, creator-friendly tools. Cons: No visual automations, ecommerce features minimal.
➡️ Try at Kit
2. Brevo — Best Free for Volume
Brevo’s free tier gives unlimited contacts but caps sends at 300 per day (~9K/month). For a small list with frequent sends, it is the most generous. Automation, transactional API, and SMS credits are usable on free.
Pros: Unlimited contacts, real automations, transactional API included. Cons: Daily send cap; branding required on free.
➡️ Try at Brevo
3. MailerLite — Best Balance of Limits
MailerLite’s free plan is 1,000 contacts and 12,000 sends per month with full automation builder access. Approval is strict — they review accounts manually — but once approved, the free tier is one of the most usable.
Pros: Full automations on free, clean editor. Cons: Approval can be slow; some features still gated.
4. Mailchimp — Best Free for Ease of Use
Mailchimp’s free 500 contacts / 1,000 sends per month is small but the easiest UI of the bunch. Customer Journey Builder is locked behind paid plans, but basic single-step automations work.
Pros: Friendliest UI, polished templates. Cons: Lowest contact and send limits, automation gated.
5. HubSpot Email Marketing — Best Free for B2B + CRM
HubSpot bundles email into its free CRM. 2,000 emails per month, segmentation by CRM properties, and HubSpot tracking pixels in every send. Branding is required on free.
Pros: Free CRM, deep segmentation, B2B-ready. Cons: Branded footer is bulky; HubSpot ecosystem upsell.
6. AWeber — Best Free for Stability
AWeber’s free plan is 500 contacts and 3,000 sends per month. Stable, simple, no surprises. One automation slot and basic landing pages included.
Pros: Long-running, stable, easy to learn. Cons: UI dated, automation extremely limited.
7. Sender — Best Hidden Gem
Sender’s 2,500 contacts / 15,000 sends per month free plan is one of the most generous. Automations, popups, segmentation, and SMS credits are all available on free.
Pros: Generous limits, automations on free. Cons: Smaller integration ecosystem.
8. Omnisend — Best Free for Small Stores
Omnisend’s 250 contacts / 500 emails per month free plan is small but ecommerce-ready. Pre-built abandoned cart, welcome series, and product blocks available on free.
Pros: Real ecommerce features on free, SMS credits included. Cons: Free limits are tiny; built for upgrading.
9. EmailOctopus — Best Free for Amazon SES Power Users
EmailOctopus runs on top of Amazon SES (or its own infrastructure on paid). Free tier is 2,500 contacts / 10,000 sends per month, with simple automation flows.
Pros: Generous limits, fair upgrade pricing. Cons: Approval is strict; reporting is basic.
10. Beehiiv Launch — Best Free for Newsletters
Beehiiv’s Launch plan is free with unlimited subscribers and unlimited sends — the most generous number on this list. Branding removal and advanced features come with Scale ($39) or Max ($99). Built specifically for newsletter operators.
Pros: Unlimited free subs, newsletter-specific tools, growth network. Cons: Branding required on free; not designed for ecommerce.
Free vs Paid: When to Upgrade
| Threshold | What Triggers an Upgrade |
|---|---|
| 500–1,000 contacts | Most free plans cap here; pay for more list capacity |
| Daily send caps | Brevo’s 300/day stops broadcast cadence |
| Automation needs | Welcome + cart + post-purchase usually requires paid |
| Branding removal | Required for serious brand sites |
| Deliverability | Dedicated IP + warm-up only on paid tiers |
| Integrations | Shopify, BigCommerce often paid-only |
Tips for Getting the Most From a Free Plan
- Pick by your bottleneck. If you have 8K subs but send rarely, Kit wins. If you have 200 subs but send daily, Brevo wins.
- Authenticate immediately. SPF, DKIM, DMARC are free. Gmail and Yahoo require them.
- Send a welcome email within minutes of signup. Even on a one-step free automation.
- Sunset inactive subscribers monthly. Free plans count them; remove unopened-in-90-days contacts.
- Plan your upgrade trigger. Decide at what contact count or revenue mark you will upgrade — and stick to it.

FAQ — Free Email Marketing Tools
Q: Are free plans good enough for a real business? A: For validation and early traction, yes. Most stores outgrow free tiers around 500–2,000 contacts.
Q: Will my emails go to spam if I use a free plan? A: Not because of the tier — but because of authentication and list hygiene. Set up SPF/DKIM/DMARC before sending.

Q: Do free plans support automations? A: Some yes (Brevo, MailerLite, Sender, Omnisend), some no or limited (Mailchimp, AWeber, Kit, EmailOctopus).
Q: When should I upgrade from free? A: When automations or contact limits start blocking growth, or when removing branding becomes important for trust.
