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
