Is my list safe with you?

Your list is your business, not ours. Here is how we keep it safe.

We never email your contacts

To check whether an address is real, we have a quiet, behind-the-scenes conversation with the receiving mail server — the same kind of check a mail server does before accepting a message. We never actually send a message to your contacts, so checking your list will not bother anyone or affect your sending reputation.

We never sell or share your data

We do not sell your list, share it, or use it to train anything. It is yours.

We delete your lists automatically

Your uploaded lists are stored securely and then deleted automatically 30 days after you create them. You can also download your results any time before then.
