Great example uses and workflows with CatchMailNot.
Case 1 - Creating one alias per website
Know when a website sells your email address, or uses it for another purpose. With CatchMailNot you can simply make up a new email address on that website's registration page.
Case 2 - Blocking
If you no longer want to receive emails from a website, just disable the alias you created for it, or disable the sender domain.
Case 3 - Replying to an email
You can reply to any email that came through CatchMailNot, and your reply will come from the alias that originally received the email. No one will know your private email address.
Case 4 - Multiple recipients
Every domain or identifier can default to multiple recipients. You can also create rules to forward certain emails to multiple addresses, BCC, or a webhook.
