Know which emails are real before you hit send, no credits needed
Verify emails before outreach
This workflow is for SDRs, account executives, and revenue operations teams working with sourced, enriched, or manually built prospect lists. It starts when a list is ready for sequencing but its email validation status is unknown or stale.
Check each address before upload, separate confirmed mailboxes from invalid, throwaway, and catch-all results, then route uncertain records for review. A good outcome is a cleaner send list, fewer avoidable bounces, and clearer decisions about prospects needing alternate contact details.

More about workflow design
Treat verification as a repeatable gate between list building and sequence enrollment. For bulk email verification, preserve result categories so sales operations can define consistent routing rules.
- Send confirmed mailboxes to the intended sequence.
- Exclude invalid and throwaway addresses, then source replacements.
- Review catch-all results separately using a team-approved risk policy.
