Brevo (formerly Sendinblue)

4.5 / 54,000 reviews

+ Unlimited contacts on all plans including free; pricing based on email volume

+ Multi-channel: email, SMS, WhatsApp, and live chat in one platform

- Free plan limits to 300 emails/day which constrains growth

“The unlimited contacts model is a game-changer. We have 15,000 subscribers but only send weekly, so Brevo costs way less than per-contact tools.”

Constant Contact

4.1 / 58,600 reviews

+ Very beginner-friendly with strong tutorials and phone support

+ Built-in event marketing tools (RSVP, ticketing) that competitors lack

- Noticeably more expensive than competitors for comparable features

“Constant Contact is reliable and the phone support is genuinely helpful, but we're paying a premium compared to what newer tools offer.”
