Engineering teams migrating from ZeroBounce (`/v2/validate` and `/v2/sendfile`) typically switch to eliminate two structural bottlenecks: credit deductions on `unknown` / `catch-all` responses and steep per-credit markups below 250,000 monthly checks. ZeroBounce separates results into primary `status` (`valid`, `invalid`, `catch-all`, `unknown`, `spamtrap`, `abuse`, `do_not_mail`) and `sub_status` (`antispam_system`, `greylisted`, `mail_server_temporary_error`, `role_based`). While granular, ZeroBounce still deducts a full prepaid credit even when a corporate Proofpoint or Mimecast gateway returns an inconclusive 451 temporary deferral.
In KaijuVerifier, our `/api/v1/verify-single` and asynchronous `/api/v1/jobs` endpoints map 1:1 to your existing ZeroBounce webhook handlers while automatically refunding 100% of inconclusive `unknown` probes. Furthermore, our adaptive anti-greylisting retry queue waits out 421/450 temporary deferrals across distributed IPv4 subnets before finalizing a verdict, turning up to 64% of ZeroBounce "unknowns" into definitive `valid` or `invalid` outcomes without manual re-uploads.
