AT&T to Discontinue AT&T Worldnet Service on March 31, 2010

The Silverpop Deliverability Team has been notified that AT&T will discontinue the Worldnet service on March 31 and transition those users over to the AT&T service platform. What does that mean for email marketers? It means that if you’re sending to those users with a @worldnet.att.net email address, it will become invalid after March 31.

AT&T is requiring that Worldnet subscribers take action to transfer their service and email address. Essentially, AT&T will be changing the subscriber’s email address from johndoe@worldnet.att.net to johndoe@att.net, but only if the subscriber requests the transfer to occur and if the att.net email address is available.

We don’t recommend that you change every email address in your list from @worldnet.att.net to @att.net in case those email addresses already belong to someone else. The Silverpop Deliverability Team does recommend that you research your list and potentially reach out to these subscribers to get an alternate email address so that they can continue to receive your emails.

For more information about this transition, please visit http://help.att.net/att795.html?platform=none.
