Lists all over the internet are being hit by listbombing.
We talk more about what listbombing is and why it happens here.
But don't despair because we've got you covered.
To prevent fake signups from entering your list, you'll want to do the following:
Clear out existing fake signups. If it's easy to spot the fake signups, you can remove them by manually deleting them from your list. However, sometimes the fake signups can blend in with legitimate ones. If this is the case, we recommend regularly pruning your list so that the fake signups will be removed as they become cold.
If you have any questions or need further help with preventing fake signups, please don't hesitate to reach out to our Support team!
