LoopSuppress

LoopSuppress is a web app (with API) that centralizes bounce handling across multiple email providers and ESPs. It ingests bounce events via webhooks, SMTP logs, and mailbox feedback loops, then normalizes them into a single taxonomy (hard, soft, block, complaint, transient). The core value is automated suppression and list hygiene rules that are consistent across tools: suppress after N events, cool-down periods for transient failures, and provider-specific handling (e.g., Gmail 4xx patterns). It also generates “why did this bounce?” explanations and recommended fixes for common misconfigurations (SPF/DKIM/DMARC alignment, rDNS, throttling). This is a combination traditional + AI app: traditional pipelines for deterministic classification, plus AI to summarize patterns, cluster new bounce strings, and draft remediation steps. It’s realistic because teams already have bounce data, but it’s scattered and inconsistently acted on.
