Verify email addresses

Sending to addresses that don't exist hurts your reputation with inbox providers. Verifying checks addresses before your first send. Invalid ones are left out of sends, and their records are kept.

Run a check

1. Open Contacts, then click Verify emails.
2. Choose the brand.
3. Optionally, enter a number in Check at most to limit how many addresses are checked. Leave it empty to check every unverified address.
4. Click Show estimate. Mosaic tells you how many addresses it would check and what that would cost. This is a dry run, and nothing is spent.
5. Click the Verify button to start. Each address is checked once.

What the results mean

Result	Meaning
Unverified	Not checked yet.
Valid	The address looks real.
Risky	The address accepts all mail, so Mosaic can't be sure it's real.
Invalid	The address doesn't work. These are left out of sends.
Unknown	The check couldn't tell.
