Mailchimp
What users love
- Intuitive drag-and-drop email builder — most-cited strength across the 12,950-review G2 corpus, with non-designers shipping campaigns same-day
- Solid deliverability and a strong ready-made template library tailored for SMB and nonprofit segments
- Wide integration ecosystem — 300+ apps including all major e-commerce platforms (Shopify, WooCommerce), CRMs (HubSpot, Pipedrive), and ads
- AI Creative Assistant for design help plus Send Time Optimization included on Standard tier and above (no per-feature surcharge)
Common complaints
- Pricing scales steeply with contact count — list growth from 500 to 10k contacts jumps Essentials from $13 to ~$110/mo (per G2 reviews)
- Unsubscribed contacts still count toward the billing total — a long-running practitioner gripe across G2 and Capterra (per G2 reviews)
- Free plan was downgraded sharply — was 2,500 contacts and 10k emails, now 250 contacts and 500 emails with no automations (per G2 reviews)
- Lower-tier support is slow and generic — live chat support is gated behind the Premium tier (per G2 reviews)
- Two parallel email builders (Legacy and New) create navigation inconsistencies and template-portability friction (per G2 reviews)
