Why Teams Switch To SendSure
Resolves catch-all & unknown results
NeverBounce's SMTP-only check marks accept-all domains "unknown" and stops there. SendSure's AI catch-all resolver — a 54K+ name-pattern database plus Gravatar, GitHub, and HIBP lookups — scores those same addresses instead of giving up on them.
Multi-signal verification depth
27 stages spanning DNS validation, disposable-domain detection, and AI-based scoring vs NeverBounce's single SMTP handshake.
More features included at every tier
Deliverability testing, blacklist monitoring, and data export/deletion tools ship on every SendSure plan — NeverBounce's base plans lack all three.
GOD Rule transparency, free credits to start
SendSure states what it actually knows and never charges for a result it can't resolve, plus gives 10 free credits to test the full platform on signup — NeverBounce offers neither.
