Verify emails before sending in Moosend
Pull contacts from your list or CRM, verify each address, and send through Moosend — only to addresses that are deliverable.
Why verify before the send
Moosend deliverability depends on low complaint and bounce rates, which verification protects. A single verification step before the send removes that risk: only deliverable addresses are emailed, and invalid, risky, disposable, and catch-all addresses are filtered out automatically.
The workflow
