MailReach

MailReach warms mailboxes, tracks reputation, runs spam tests, and checks domain and inbox health. It is positioned for B2B outreach teams that need warmup and deliverability diagnostics together, with pricing driven by mailbox count and spam test credits.

Judged purely as an API. What the request contract guarantees on retry, how complete the webhook event coverage is, whether suppressions are readable and writable programmatically, and how much the message log retains when something needs debugging in production.

Against high-frequency programmatic sends where a missed delivery is a product failure, MailReach covers webhook coverage and event stream, and does not cover idempotency keys, the suppressions API, batch sending, and SDK breadth. Whether that gap matters depends on how central those are to the build.
