How Brevo (formerly Sendinblue) and Kit (formerly ConvertKit) compare
Brevo (formerly Sendinblue) is a value-priced email plus SMS plus light CRM platform popular with European SMBs. It's broad: email campaigns, transactional sending, SMS, chat, basic CRM. Wysera takes a different shape: PostWyse for content drafting with AI visibility tracking, OpsWyse for a real CRM with Wyse drafting lifecycle email tied to deals.
Kit (the rebranded ConvertKit) is the email platform creators love: clean newsletter sending, tag-based subscriber management, paid newsletter monetization, creator network. It's purpose-built for solo creators and small newsletter publishers. Wysera is a different shape: PostWyse for marketing content, OpsWyse for CRM and lifecycle email, all drafted by Wyse from one brand brief. Different audiences, different jobs.
Which should you choose?
Pick Brevo (formerly Sendinblue) if you fit its sweet spot: Value-conscious SMBs running email plus SMS plus transactional sending, with light CRM needs and a preference for European data residency. Brevo is the right call when email volume is the constraint. Pick Kit (formerly ConvertKit) if you're closer to Solo creators, paid newsletter publishers, online course sellers, and anyone whose primary product is the newsletter itself. Kit is the right tool when the audience is the business. If your real problem is paying for too many overlapping tools, neither single choice solves it — that's the case for consolidation.
