Warmy

Warmy is an email warmup and deliverability platform for senders trying to build or repair mailbox reputation. The official accessible docs clearly describe a 7-day trial with one connected mailbox and limited daily seed emails. Paid pricing was not exposed in the crawled official pricing docs, so this profile avoids quoting third-party price claims.

A SaaS product sends on behalf of its customers, so the deciding factors are tenant isolation, whether suppressions can be scoped rather than global, and whether support can answer why one specific account did not receive one specific email. Lifecycle automation and transactional sending usually need to coexist.

Against trial expiry notices, dunning, onboarding sequences, and per-tenant transactional mail, Warmy covers multi-tenant support, event stream, and scheduling, and does not cover the suppressions API and webhook coverage. Whether that gap matters depends on how central those are to the build.
