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.”

Kit (formerly ConvertKit)

4.5 / 5410 reviews

+ Purpose-built for creators with excellent tagging and subscriber segmentation

+ Clean, minimal UI makes it very easy to set up automations and sequences

- Email template design is intentionally plain-text focused; limited visual design options

“Kit keeps me focused on writing and connecting with my audience instead of fighting with a complicated email builder. The tagging system is brilliant.”
