Close CRM Email Verification

Verify before import — not after bounce.

The right moment to verify is before contacts are imported into Close and before any sequence is activated. Once contacts are in an active sequence, removing them requires manual intervention mid-campaign. The bounce has likely already occurred.

CRM migrations deserve special attention. Moving contact data from one CRM to Close often surfaces contacts that were never verified, have been inactive for years, or were added through a data source that no longer reflects current email status. Verify before the migration completes, not after the first sequence runs.

Route each result before Close sees it.

Maintain a suppression file that spans all your Close sequences. Addresses that bounce or opt out from one sequence should not re-enter through a different import or a new sequence enrollment. Close does not automatically prevent a contact from entering a new sequence if the contact record still exists.

After the list is verified.

Once verified contacts are in Close:

• Valid contacts enroll in your primary sequences at standard cadence
• Catch-all contacts run in a lower-volume, separately monitored sequence
• Role-based contacts get messaging that fits a shared or team inbox context
• Invalid and risky contacts are suppressed and excluded from all future sequence enrollments
• Unknown contacts sit in a review queue before any sequence decision

The CRM record for suppressed addresses should be updated to reflect their status. That prevents the same address from being re-enrolled when a new sequence is created or a Smart View filter is applied without a suppression check.
