When listing out your subscribers in your account, you may see something that appear like this:
When you see "Confirmation Pending" in the "Status" column, it means we've sent a confirmation message to that subscriber, while they have yet to click on the link inside of the message to confirm their subscription.
This would be as a result of any of the following:
- "Confirmed Opt-In" being enabled for your sign up forms
- Manually adding subscribers through the "Add" or "Import" pages with confirmation turned on
- Security reasons triggered in our system
As soon as your subscriber clicks on the link in the message they were sent, they'll become active in your list and begin to receive the messages you've scheduled.
