How it works

Any requests to join a list are emailed back a Confirmation Message. The Subject line contains a random number that our computer generates each time.

How subscribers are added

When the subscriber replies (or clicks a link inside the email body), our machine matches up the random number, adds them to your list, and sends them the Welcome Message.

How it protects you

This prevents pranksters and viruses from getting other people signed up to your list.

Better delivery results

The lack of spam complaints allows us to stay off the various blacklists that could restrict delivery of your messages.
