AISend vs Brevo (Sendinblue)
A Developer-First Brevo Alternative
Brevo (formerly Sendinblue) tries to do everything — CRM, marketing, transactional, SMS. AISend does one thing well: a clean transactional email API for developers. If you want an email API without the marketing-suite bloat, AISend fits.
Why Developers Switch from Brevo (Sendinblue)
- Jack of all trades — transactional email is not the core focus
- Broad marketing platform with features most developers don't need
- Free tier has a 300 emails/day sending cap
- Marketing-first API, not a single clean send endpoint
