How to verify email addresses in a CRM
An invalid email is worse than a blank one: it looks usable, so a rep or campaign wastes effort on it and outreach bounces.
Verification catches bad addresses at capture and on refresh, protecting deliverability and rep time.
Short answer
Verify email addresses by checking format, confirming the domain exists and accepts mail, and validating the mailbox where possible, then flagging or correcting bad addresses before they are used. Verify at capture so undeliverable emails never route as real leads, and re-verify periodically because addresses decay as people change jobs.
Step by step
Check format and domain
Confirm the address is well-formed and its domain exists and accepts mail. This catches typos and dead domains immediately.
Validate the mailbox where possible
Where the provider allows, confirm the specific mailbox exists, distinguishing a real address from a plausible-looking fake.
Flag or correct at capture
When a lead comes in, verify before routing, so undeliverable addresses are flagged or corrected rather than worked as real.
Re-verify on a schedule
Because emails decay as people leave jobs, re-verify periodically and flag addresses that have started bouncing.
Verify at capture, not after a bounce
Discovering a bad email when a campaign bounces is too late - deliverability already took the hit and the rep already wasted time. Verifying at capture stops undeliverable addresses from ever routing as real leads, and scheduled re-verification catches decay before it bounces.

Ardovo verifies emails at capture and re-verifies on a schedule, so undeliverable addresses are flagged before they route and caught as they decay. Rook keeps deliverability high and stops reps from wasting time on dead addresses.
Frequently asked questions
Why verify email addresses in a CRM?
Because an invalid email looks usable but bounces, wasting rep time and hurting sender reputation. Verifying catches typos, dead domains, and fake addresses before they are worked or emailed, protecting both deliverability and productivity.
When should you verify emails?
At capture, so undeliverable addresses never route as real leads, and periodically after that, because emails decay as people change jobs. Verifying only once lets addresses go bad silently until a campaign bounces off them.
What makes an email address invalid?
A malformed format, a domain that does not exist or reject mail, or a mailbox that is not real - plus addresses that were valid but decayed when the person left. Verification checks format, domain, and, where possible, the mailbox itself.
