About Mailchimp
Mailchimp is the most recognized email marketing platform — 12 million customers, the brand that non-technical stakeholders recognize. The default choice until 2021 when Intuit acquired it for $12B and began restricting the free tier significantly.
**Deliverability benchmark (March 2025, identical seed list across platforms):**
| Platform | Gmail inbox % |
|---------|-------------|
| Beehiiv | 94.1% (#1) |
| ActiveCampaign | 93.1% (#2) |
| ConvertKit | 92.3% (#3) |
| Mailchimp | 88.4% (#5) |
Mailchimp''s 88.4% Gmail placement is the lowest among major platforms — meaning 11.6% of emails go to spam or promotions. At 10,000 subscribers, that''s 1,160 people not receiving the email per send.
**Free tier (2025 reality):**
500 contacts, 1,000 sends/month, Mailchimp branding on all emails, no A/B testing, no scheduled sends. ConvertKit''s free tier offers 10,000 subscribers — 20x more.
**Where Mailchimp still wins:**
- **Brand recognition**: clients and stakeholders recognize Mailchimp, reducing internal buy-in friction
- **E-commerce integration**: Shopify, WooCommerce, and BigCommerce purchase sync for behavioral targeting
- **Multi-channel**: email + SMS + social ads + landing pages + postcards from one platform
**Customer Journey Builder:**
Visual automation based on website behavior, purchases, and email engagement. A customer who views the pricing page 3 times gets a discount offer. A customer who abandons a cart gets a reminder series. These behavioral triggers are Mailchimp''s genuine strength.
