Some Features of SubscribemePro Include:

Multiple List Concurrent Subscription and Unsubscription. Offer your subscribers many lists to choose from and subscribe/unsubscribe all with one addition of their address.

Batch Unsubscription/Removal. If you are managing large lists, you may receive many undeliverable e-mails. Our Enterprise edition allows you to unsubscribe all of your bounced addresses all at once! Please Note: This feature does not automatically remove addresses.

Using our Invitation feature, you can do some pro-active list building by adding addresses that you may gather from other sources to your mailing. These added addresses will receive an invitation, which you can create/modify, to invite them to join your mailing list, along with a link to do so! Since these addresses are not part of your mailing list, they will not be stored for future mailings, unless the receiver subscribes with the link sent via e-mail.

Tested to over 2,000,000 (Yes, that's MILLION) e-mails! Administration interface gives you the ability to Add or Import a list, Edit Configurations, Send Mass Mailings, Track Results of your mass mailings, Log Off of your administration "Session" for security purposes, see and Edit the Details of each list, and last but not least, Delete the list itself.
