They make their money on paid plans, not free tiers. The free tiers are designed to show you what you're missing — not to give you everything you need.
That said: free email marketing tiers are more capable than they've ever been, and many creators, ai-writing-tools-for-small-businesses-2026" title="Best AI Content Optimization Tool Worth Trying" class="internal-link">AI Writing Tools for Small Businesses in 2026" class="internal-link">small businesses, and startups can run legitimately effective email programs at zero cost. The key is understanding exactly what each platform's free tier includes and when the paid upgrade actually earns back its cost.

Platform-by-Platform Breakdown
Mailchimp Free
Mailchimp's free tier is the most recognized name in email marketing, but it's no longer the most generous. Free includes:
- 500 contacts
- 1,000 emails/month (500 emails every 24 hours)
- 1 audience (list)
- Basic templates
- Basic reporting (opens, clicks)
- Mailchimp branding on emails
What's missing:
- Multi-step automation (free tier only has a single-email automation, not sequences)
- A/B testing
- Custom-branded landing pages
- Advanced segmentation
- 24/7 customer support
Honest assessment: Mailchimp's free tier was the clear leader 3–4 years ago. In 2026, both Brevo and Kit have better free tiers for most use cases. Mailchimp's brand recognition keeps it popular, but if you're starting fresh, you can do better for free elsewhere.
Mailchimp free is best for: Very early-stage businesses who might grow into Mailchimp's ecosystem and want name-brand familiarity. Under 500 contacts with occasional send volume.
Brevo (formerly Sendinblue) Free
Brevo's free tier is unusually generous because it's priced on email volume, not contact count:
- Unlimited contacts stored — no contact limit
- 300 emails per day (9,000/month)
- Marketing automation (basic, including multi-step)
- Transactional email (important for developers)
- Brevo branding on emails
- SMS marketing (credits not included, but feature available)
The unlimited contacts + automation combination on a free tier is rare. A list of 10,000 contacts sending weekly emails to segments of 1,000–2,000 at a time can work on Brevo free indefinitely, just with the volume limit.
Brevo free is best for: Businesses with larger contact lists who send infrequently, or any business that needs basic automation without paying. European businesses benefit from Brevo's EU data center options and GDPR tools.
Kit (ConvertKit) Free
Kit's free tier changed the creator email marketing landscape. Previously, ConvertKit's free tier was bare-bones. After rebranding to Kit, their free tier now includes:
- Up to 10,000 subscribers
- Unlimited email sends
- Basic landing pages and forms
- Broadcasts (one-time newsletters)
- No Kit branding on sent emails (rare for free tiers)
- No automation sequences (free is broadcast-only)
The 10,000-subscriber free limit with no send volume cap and no branding is remarkable. A newsletter with 5,000 subscribers sending weekly issues can run entirely on Kit free.
The catch: no automated email sequences (welcome sequences, drip campaigns) on the free tier. For a pure newsletter without automation, Kit free is the best option available.
Kit free is best for: Creators, bloggers, and newsletter publishers who send regular broadcasts to a list. Anyone building a newsletter audience before monetizing.
Beehiiv Free
Beehiiv was built specifically for newsletter publishers and has a generous free tier:
- Up to 2,500 subscribers
- Unlimited sends
- Custom newsletter publication
- Basic analytics
- Subscribe forms and web presence
Beehiiv's paid tiers add monetization features (paid subscriptions, boosts/referral programs, ad network). The platform is designed for newsletters as a business model — not generic email marketing.
Beehiiv free is best for: Newsletter creators building toward a monetized newsletter. The platform is designed for the creator economy and the upgrade path makes sense for content-first businesses.
MailerLite Free
MailerLite gives you 1,000 subscribers and 12,000 emails/month with:
- Automation workflows (included free — a key differentiator)
- Landing pages
- Embeds and pop-ups
- 24/7 email support on free
- Very little branding on free emails
MailerLite is consistently rated as one of the cleanest, easiest-to-use email marketing platforms. The free tier is genuinely capable and the paid upgrade ($9/month for 500 contacts) is among the most affordable.
MailerLite free is best for: Small businesses and bloggers who want clean design, easy automation, and low overhead. The free tier is genuinely usable for growing a list.
What You Actually Lose on Free Tiers
After reviewing all the major platforms, here's what free tiers almost universally don't include:
Advanced automation sequences — Most free tiers limit you to single-step automations or none at all. Welcome sequences, abandoned cart follow-ups, lead nurturing drips all require paid plans.
A/B testing — Testing subject lines, send times, or content variations is nearly always paid.
Advanced segmentation — Segmenting by behavior (link clicks, purchase history, tags) requires paid tiers on most platforms.
Custom domains for landing pages — Free tiers often give you a platform subdomain for landing pages.
Priority support — Free tiers get community support or email support with slower response times.
Removed branding — Most platforms put "Sent via [Platform]" or "Powered by [Platform]" in free emails (Kit is the notable exception).
When Does Upgrading Actually Pay Off?
This is the honest answer most review sites avoid: most small creators and small businesses don't need to pay for email marketing until they're actively generating revenue from email.
The upgrade makes financial sense when:
You're generating revenue from email. If your email list is directly driving sales, the ROI calculation is simple. A 1,000-person list converting at 2% with a $50 average order generates $1,000/month. Paying $20–30/month for better automation to improve that conversion rate is obvious.
Automation would save more time than it costs. A welcome sequence that would take 2 hours/month to handle manually, automated for $15/month, is worth it if your time is worth more than $7.50/hour.
You're hitting contact limits. If you have 2,000 subscribers on Mailchimp free (which caps at 500), you need to either upgrade or switch platforms. Switching is often the better answer — migrate to Kit free (10,000 subscribers) or Brevo free (unlimited contacts) before paying.
You're doing e-commerce. Abandoned cart sequences, post-purchase follow-ups, and win-back campaigns require automation. The revenue these sequences generate almost always justifies the cost.
The upgrade is NOT worth it when:
- You're under 1,000 subscribers with no clear revenue connection
- You're sending occasional newsletters (less than twice a month)
- You haven't tested your basic email program yet
- You're in "building" phase — focus on growing the list first
The Real Cost Comparison at Scale
| Contacts | Mailchimp | Brevo | Kit | MailerLite |
|---|---|---|---|---|
| 500 | Free | Free | Free | Free |
| 1,000 | $13/mo | Free | Free | Free |
| 2,500 | $27/mo | Free | Free | $15/mo |
| 5,000 | $50/mo | $22/mo | Free | $25/mo |
| 10,000 | $80/mo | $35/mo | Free (basic) / $25 (automation) | $50/mo |
At 5,000 subscribers, Kit's free tier (unlimited sends, no automation) or Brevo's free tier ($22/month for full automation) dramatically undercut Mailchimp's pricing.
The takeaway: If you're currently paying Mailchimp $50–80/month for a 5,000–10,000 person list, switching to Kit or Brevo and staying free (or paying $22–35/month for Brevo's automated tier) is an immediate cost reduction with no capability loss.
Recommendations
Just starting out (under 1,000 subscribers): Kit free. Unlimited sends, no branding, easy to use. Upgrade only when you need automation sequences.
Creator or newsletter publisher: Kit free or Beehiiv free. Both are designed for this use case.
Small business with automation needs: Brevo free or MailerLite free. Both include automation on the free tier.
E-commerce: Klaviyo has the most powerful e-commerce integration — it's free up to 500 contacts and worth the premium at scale. Alternatively, Omnisend free tier is designed for e-commerce with strong automation.
Already on paid Mailchimp: Audit your list and automation needs. If you're under 10,000 subscribers and don't need advanced features, Kit or Brevo will likely save you $30–70/month.
Frequently Asked Questions
Is Mailchimp still good in 2026? It's capable but no longer the best value. Competitors have surpassed it on free tier generosity. Mailchimp makes sense for businesses already deeply integrated with its ecosystem or using Mailchimp's e-commerce features.
Can I switch email platforms without losing my list? Yes — export your contacts as a CSV from your current platform and import into the new one. You may lose automation history and some engagement data, but contact information transfers cleanly.
Does email deliverability differ between free and paid? Slightly. Paid tiers on most platforms give access to dedicated IP addresses and better deliverability support. For most small senders, shared IP pools work fine. Deliverability issues are more often caused by list quality and email content than platform tier.
What's the best free email marketing tool for a side project? Kit free. 10,000 subscribers, unlimited sends, no branding. It's hard to beat for a side project.
Is Klaviyo worth the cost for e-commerce? For Shopify or WooCommerce stores generating $10K+/month, Klaviyo's behavioral automation almost always generates more revenue than it costs. For smaller stores, start with Klaviyo free (500 contacts) and upgrade when your list grows.
