Does Constant Contact verify emails on its own?

Constant Contact validates email format at signup and removes hard bounces after sending, but it does not proactively verify whether existing contacts are still deliverable. Truelist performs full SMTP-level verification.

How do I connect Constant Contact to Truelist?

Click the "Connect Constant Contact" button in your Truelist dashboard. You will authorize via OAuth and your contact lists sync automatically. No API keys required.

Will verifying contacts lower my Constant Contact bill?

Yes. Constant Contact charges by total contacts. Removing invalid emails can move you to a lower pricing tier, often saving more than the cost of verification.

How often should I verify my Constant Contact list?

We recommend verifying quarterly or before any major campaign. Email addresses decay at roughly 2-3% per month, so regular cleaning keeps your list and costs in check.
