A common worry is that checking a list might "use up" the addresses or hurt your standing with email providers. It does not.
We never send a real message
We have a quiet, behind-the-scenes conversation with the receiving mail server and ask whether it will accept the address. We stop before any actual email is delivered. Your contacts never see anything, and nothing lands in their inbox.
Why this protects you
- No messages are sent, so there is nothing to bounce during a check.
- Your contacts are not disturbed.
- Your sending reputation is not affected by checking.
Tip
In fact, checking your list before you send is one of the best ways to protect your reputation — it removes the bad addresses that would have bounced.
