BounceClinic

BounceClinic is a web app (with optional API) that turns raw bounce logs into actionable deliverability fixes. It ingests SMTP responses and webhook events from major ESPs, normalizes them into a consistent taxonomy (hard/soft, policy, auth, mailbox full, spam-related, DNS, etc.), and recommends concrete next steps: suppress, retry with backoff, segment, warm up, adjust cadence, or fix authentication. It also detects patterns that usually get missed—like a single domain suddenly rejecting due to DMARC alignment, or a list source producing disproportionate unknown-user bounces. The app provides domain-level and campaign-level dashboards, automated suppression list exports, and alerting when bounce rates cross thresholds that risk account suspension. It’s not magic: it won’t “guarantee inboxing,” but it will reduce wasted sends, prevent reputation damage, and shorten time-to-root-cause when bounces spike.
