Brevo
All-in-one with a generous daily free tier.
Brevo (formerly Sendinblue) bundles transactional, marketing, CRM, and SMS. The 300-emails-per-day free tier is one of the most generous in the market. Best as an all-in-one for small businesses; pure-API users may find the surface broader than they need.
Reliable for marketing and transactional; per-day free-tier limits prevent spam abuse.
Small businesses that need email plus marketing plus SMS in one place.
- › Generous permanent free tier
- › Marketing plus transactional plus SMS
- › Inbound parsing
- › Surface area is large; pure-API teams may not want the rest
- › UI can feel busy
