Warmy vs MailReach
Warmup trial and reputation workflow versus published per-mailbox pricing and bundled spam tests.
What matters for developers picking email infrastructure
The question here is which one a backend engineer would rather operate. That means SDK depth in the language already in use, whether a retry can safely be replayed, how much the event log tells you when a customer says the email never arrived, and whether the pricing curve stays sane as volume grows.

| Free tier | 7-day trial, no credit card, 1 mailbox, 15 to 50 seed emails/day | No permanent free plan published |
For a developer-owned stack running password resets, receipts, and magic links shipped from application code, MailReach takes every priority that separates them here (developer experience and webhook coverage), while Warmy matches it on the rest. On free tier, Warmy offers 7-day trial, no credit card, 1 mailbox, 15 to 50 seed emails/day against No permanent free plan published from MailReach. That ordering reflects this audience. Weigh the same table differently and the answer changes.
