_Free tool_

# Is this address real, or a ghost?

Check one email address before it goes on your list. We ask the mailbox
provider whether it will accept mail, and flag typos, disposable addresses and role inboxes like info@.
Free, no signup, and we don't keep the address you check.

Email address

Check address

One address at a time. You can check a few an hour.

## Letterhead finds the ghosts already on your list.

Every Letterhead newsletter sorts its readers into engagement groups, including
Ghosts: readers who have stopped opening and clicking. Each group shows how many readers it holds, so you
can size it before you send.
