Teams with API-critical workflows that cannot tolerate multi-day support response times or extended escalation cycles. Multiple reviews in public channels describe delayed responses from support.
Buyers that require a deliverability operations platform rather than a verification-focused tool. If inbox placement testing, blacklist monitoring, and DMARC monitoring are required in the same platform, consider providers that explicitly market those capabilities.
Operations that frequently upload very large files through the web UI. Review reports reference a 100MB CSV limit, which can increase operational overhead.
