Brevo

Brevo is an email and SMS marketing platform that handles both campaigns and transactional messages for membership sites and communities. Originally launched as Sendinblue, it's been used by growing communities for years to automate member outreach across multiple channels. The platform includes marketing automation workflows, detailed subscriber segmentation, and basic CRM capabilities built in.

Brevo fits membership and community sites that want both email and SMS in a single tool. It's a practical middle option, more features than basic email tools, lower cost than enterprise platforms, and a free tier that grows affordably even for large subscriber lists.
