With free options this good, paying for email marketing is a real decision. Here's exactly when free is enough and when paid tools earn their cost back.
Every Free Email Tier, Compared Honestly
| Platform | Free Limit | Sends | What's Walled Off |
|---|---|---|---|
| Kit (ConvertKit) | 10,000 subscribers | Unlimited | Advanced automations, integrations |
| beehiiv | 2,500 subscribers | Unlimited | Ad network, referral program, A/B testing |
| Brevo | 100,000 contacts | 300/day (9,000/mo) | Brevo branding, daily send limit, no A/B testing |
| Mailchimp | 250 contacts | 500/month | Most automations, A/B testing, advanced reporting |
| Buttondown | 100 subscribers | Unlimited | Custom domain, automations, paid subscriptions |
| Substack | Unlimited | Unlimited | 10% revenue cut on paid subs, limited design, no custom domain |
When Free Is Genuinely Enough
Stay on free if:
- You have fewer than 2,500 subscribers (beehiiv Launch handles this perfectly)
- You're a creator sending a weekly newsletter without complex automation
- You don't need advanced segmentation or A/B testing
- You're not monetizing through ads or referral programs yet
- Kit's 10,000 subscriber free tier covers your entire list
The best free strategy:Start on beehiiv Launch (free up to 2,500 subscribers with unlimited sends and a custom domain). If you outgrow it before you're ready to pay, move to Kit Newsletter (free up to 10,000 subscribers). Between these two, most creators can go years without paying a cent.
When to Start Paying (And What to Pay For)
| Trigger | Best Paid Option | Price | Why |
|---|---|---|---|
| Need automation sequences | ActiveCampaign Starter | $15/mo (1,000 contacts) | Best automation builder in email marketing |
| Want to monetize newsletter | beehiiv Scale | $49/mo | Ad network + referral program can pay for the plan |
| Outgrew Kit free (10K+) | Kit Creator | $39/mo (1,000 subs) | Unlocks automations, integrations, live chat support |
| Large list, low budget | Brevo Starter | $9/mo (5,000 emails/mo) | Store unlimited contacts, pay only for sends |
| E-commerce automation | Mailchimp Standard | $20/mo (500 contacts) | Product recommendations, customer journey builder |
The Annual Cost Comparison
| Scenario | Free Option | Paid Option | Annual Difference |
|---|---|---|---|
| Creator, 5K subs | Kit free ($0) | beehiiv Scale ($49/mo = $588/yr) | $588/yr for monetization tools |
| Business, 1K contacts | Brevo free ($0) | ActiveCampaign Starter ($15/mo = $180/yr) | $180/yr for automation |
| E-commerce, 5K contacts | Mailchimp free (capped at 250) | Mailchimp Standard ($20/mo = $240/yr at 500) | $240/yr+ (scales with contacts) |
The Decision Framework
1. Are you a creator or a business?
- Creator: Start on beehiiv Launch (free). Move to Kit free if you need more than 2,500 subs. Pay for beehiiv Scale ($49/mo) when you want to monetize.
- Business: Start on Brevo free (100K contacts, 300 sends/day). Pay for ActiveCampaign ($15/mo) when you need automation sequences.
2. Do you need automation?
- No: Stay free. Kit and beehiiv free tiers handle basic newsletters perfectly.
- Yes: ActiveCampaign Starter ($15/mo) has the best automation builder. Kit Creator ($39/mo) is simpler but creator-focused.
3. What's the revenue impact?
If your email list generates $500+/month in revenue (through products, services, or ads), paying $15–$49/month for better tools is a clear win. If your list doesn't generate revenue yet, stay free until it does.
Frequently Asked Questions
Which email platform has the best free tier?
Kit (ConvertKit) has the most generous free tier at 10,000 subscribers with unlimited sends. beehiiv is the best for newsletters specifically, with 2,500 subscribers, custom domain, and unlimited sends. Brevo wins for contact storage (100,000 contacts free) but limits you to 300 sends/day.
Is ActiveCampaign worth $15/month?
Yes, if you need automation. ActiveCampaign's automation builder is genuinely the best in the category. For $15/month (Starter, 1,000 contacts), you get email marketing and basic automations. The Plus plan at $49/month adds CRM, landing pages, and lead scoring.
Should I pay for Mailchimp?
Probably not. Mailchimp's free tier is the worst (250 contacts, 500 sends) and its paid plans are expensive relative to alternatives. Mailchimp Essentials starts at $13/month for 500 contacts. Brevo Starter gives you 5,000 emails/month for $9/month with unlimited contacts. The main reason to pay for Mailchimp is deep e-commerce integration with Shopify.
When does Substack stop being free?
Substack is always free to use, but takes a 10% cut of paid subscription revenue plus Stripe fees. If you earn $5,000/month from paid subscribers, Substack takes $500/month. At that scale, beehiiv Scale at $49/month is dramatically cheaper and gives you more control.
