An Important Issue for Email Verification
The most overlooked part of email verification is not the tool, it is the timing. Verify at the moment data enters your system and again before big sends.
Teams usually ask which tool to use. The more important question is when to verify.
Verify at the door
An address typed into a form is at its most fixable right then. A real-time check can ask the visitor to correct "gmial.com" before the address ever reaches your database.
Verify before large sends
Addresses decay. People change jobs, mailboxes are closed and domains expire. A list that was clean six months ago can already contain a noticeable share of dead addresses. Check before any large campaign.
Verify imported lists immediately
Event lists, partner exports and old CRM files are the usual source of bad data. Verify them before they are merged with your active audience, never after.
Keep a record
Store the verification result and date with each contact. It lets you skip addresses checked recently and re-check only the ones that are due.
A simple routine
- Real-time check on every sign-up form
- Bulk check on every imported file
- Re-check inactive contacts every few months and before big campaigns
