At the smallest scale, every platform offers a free plan. But they're not equal:
| Platform | Free Tier Limit | Email Sends | Key Limitation |
|---|---|---|---|
| Mailchimp Free | 250 contacts | 500 emails/mo | Mailchimp branding, no scheduling |
| Kit Free | 10,000 subscribers | Unlimited broadcasts | No visual automation builder |
| beehiiv Free | 2,500 subscribers | Unlimited sends | beehiiv branding, no custom domain email |
Verdict at <500 subscribers
Mailchimp Free caps at 250 contacts — you'll outgrow it almost immediately. Kit Free supports 10,000 subscribers with unlimited broadcasts. beehiiv Free supports 2,500 subscribers. Both are strictly better at this tier. Mailchimp's free plan was gutted in 2023 and is no longer competitive.
The Exact Thresholds: Mailchimp vs. beehiiv at Every Tier
| Subscribers | Mailchimp Standard | beehiiv Plan | Monthly Savings | Annual Savings |
|---|---|---|---|---|
| 2,500 | $20/mo | Free ($0/mo) | $20/mo | $240/yr |
| 5,000 | $55/mo | Scale $49/mo | $6/mo | $72/yr |
| 10,000 | $100/mo | Scale $49/mo | $51/mo | $612/yr |
| 25,000 | $230/mo | Scale $49/mo | $181/mo | $2,172/yr |
| 50,000 | $385/mo | Max $109/mo | $276/mo | $3,312/yr |
The gap widens as you grow. At 10,000 subscribers, beehiiv saves $612/year. At 50,000 subscribers, the savings hit $3,312/year. Mailchimp's pricing scales linearly with your list. beehiiv's pricing has flat tiers that absorb growth.
The Contact Counting Trap
Mailchimp counts contacts differently from most email platforms, and this is where hidden costs appear:
- Unsubscribed contacts count toward your limit. If someone unsubscribes, Mailchimp keeps them in your audience and charges you for them. You have to manually archive or delete unsubscribed contacts to stop paying for them.
- Non-subscribed contacts count too. Contacts who were added via e-commerce integrations or API but never opted in still count toward your contact tier.
- Duplicates across audiences count multiple times. If the same email exists in two different audiences, Mailchimp counts them as two contacts.
- Archived contacts don't count — but archiving them removes all their data (tags, activity, custom fields). You can't just “pause” a contact.
Real-world impact
A newsletter with 10,000 subscribers might have 12,000–15,000 total contacts in Mailchimp after accounting for unsubscribes and non-subscribed contacts. That pushes you from the $100/mo tier into the $150–$170/mo tier. On beehiiv, you pay based on active subscribers only. The contact counting difference alone can add 20–40% to your real Mailchimp bill.
When Mailchimp Still Wins
Mailchimp is not always the wrong choice. It's still competitive when:
- You need e-commerce integrations. Mailchimp's Shopify, WooCommerce, and BigCommerce integrations are mature. Product recommendations, abandoned cart emails, and purchase-based segmentation work out of the box.
- You need a visual automation builder (and don't want to pay for beehiiv Max). Mailchimp's automation builder on Standard ($20/mo+) is more capable than beehiiv Scale's automation features.
- Your team already knows Mailchimp. Switching cost is real. If your team is productive on Mailchimp and your list is under 5,000, the savings from switching may not justify the retraining time.
What to Do Instead
Decision framework by subscriber count:
- Under 2,500 subscribers: Use beehiiv Free or Kit Free. Both are superior to Mailchimp Free (which caps at 250 contacts). Zero reason to start on Mailchimp in 2026.
- 2,500–10,000 subscribers: beehiiv Scale ($49/mo) matches or beats Mailchimp Standard at every contact tier. Kit Creator ($25/mo for up to 1,000 subs, scaling up) is also competitive.
- 10,000–50,000 subscribers: beehiiv Scale at $49/mo saves $612–$3,312/year vs. Mailchimp Standard. This is the range where switching pays for itself within 1–2 months.
- 50,000+ subscribers: beehiiv Max ($109/mo) vs. Mailchimp Standard ($385/mo). Annual savings of $3,312. At this scale, the migration effort is a rounding error compared to the cost difference.
Before you switch:Export your full subscriber list from Mailchimp (Audience → All contacts → Export), including tags and custom fields. Clean the list first — remove unsubscribed contacts, bounces, and anyone who hasn't opened an email in 6+ months. A clean migration is worth more than a fast one.
Frequently Asked Questions
Does Mailchimp really count unsubscribed contacts?
Yes. Unsubscribed contacts remain in your audience and count toward your contact tier unless you manually archive or permanently delete them. This is Mailchimp's most criticized pricing policy. Other platforms like beehiiv and Kit only count active subscribers.
Is beehiiv really $49/mo for up to 25,000 subscribers?
Yes. beehiiv Scale is $49/month and supports up to 100,000 subscribers on the current pricing page. The price does not increase with subscriber count within the tier. beehiiv Max at $109/month adds custom email domains, priority support, and advanced analytics.
What about Kit (ConvertKit) pricing?
Kit Free supports up to 10,000 subscribers with unlimited broadcasts but no visual automation builder. Kit Creator starts at $25/month for up to 1,000 subscribers and scales based on subscriber count. At 10,000 subscribers Kit Creator is roughly $100/month — similar to Mailchimp Standard but with better creator-focused features.
How hard is it to migrate from Mailchimp?
Subscriber list migration takes 1–2 hours (export CSV, clean it, import to new platform). The harder parts are rebuilding automations (1–3 days), updating signup forms on your website, and warming your new sending domain (1–2 weeks of gradually increasing sends). Total realistic timeline: 2–3 weeks for a clean migration.
