BounceRadar

BounceRadar is a web app (with optional API) that centralizes bounce handling across multiple email providers (SES, SendGrid, Mailgun, Postmark). It ingests bounce events, normalizes them into a consistent taxonomy (hard, soft, block, spam, policy, DNS, content), and automatically applies suppression rules with audit trails. The core value is fast root-cause visibility: which campaigns, templates, domains, or IPs are driving bounces, and what changed right before rates spiked. It also includes a “deliverability incident” workflow: alerts, owner assignment, recommended fixes, and postmortem notes. This is not a magical deliverability fixer—if your list quality is bad, it will still hurt—but it will prevent repeated sends to bad addresses, reduce provider complaints, and shorten time-to-diagnosis when bounces surge. Pricing would be usage-based (events/month) plus seats for teams.
