What it is, in our words
The send layer: campaigns, leads, replies, mailboxes and warmup behind an API-first product.
What we measured
The best argument in our dataset for buying on architecture rather than on feature count. Full REST across campaigns, leads, replies, email accounts and warmup, plus webhooks, all documented.
Built API first, which is why we put it at S for anyone running a coding agent and around A for anyone who is not.
Surface we measured: community MCP server, no CLI, full REST, tier S.
Vendor
EmailBison. We link out and make no claim about their current pricing, terms or roadmap.
