Brevo
Brevo, the platform formerly known as Sendinblue, bundles email marketing, SMS, marketing automation, transactional email, and a lightweight CRM into one product with a pricing model that quietly undercuts most of the industry: you pay for email volume, not list size. That flips the usual math - a 50,000-contact list that gets one monthly newsletter costs a fraction of what Mailchimp-style per-subscriber pricing would charge. The free tier is genuinely usable at 300 emails per day with unlimited contacts. The honest knock: the email editor and template library feel more functional than beautiful, the interface can feel sprawling as you cross between marketing, CRM, and transactional modules, and daily send caps on the free plan make one-shot blasts awkward. Buy it if your list is big and your send cadence is modest. Skip it if you want best-in-class editor polish or creator-focused features - Beehiiv and Kit serve that crowd better.
Why we rate it
- Pay-by-volume pricing: unlimited contacts on every plan, including free
- Free tier (300 emails/day) is one of the most generous in the category
- Email, SMS, automation, transactional email, and CRM under one roof
Keep in mind
- 300/day cap on the free plan makes single large blasts impractical
