Brevo

Brevo (formerly Sendinblue) offers a genuinely integrated approach to marketing by bundling email, SMS, and basic CRM tools into one platform. The free tier charges based on daily sending volume, not subscriber count, which can suit growing businesses that want to experiment without upgrading.

The platform targets mid-market companies that need reliable multi-channel marketing without splitting tools across vendors. SMS integration is native rather than bolted on, making it useful for campaigns that reach customers across both channels.
