Constant Contact

Constant Contact provides a variety of online marketing services, including e-mail marketing. Several A2 Hosting packages include a free trial of Constant Contact that you can use to help improve your web site's online presence.

When you use Constant Contact, you may receive a “non-existent address” error. This error can be caused by a variety of issues, but one of the most common reasons is that Constant Contact servers do not process e-mails that are sent to non-specific addresses. For example, addresses such as [email protected], [email protected], and [email protected] are all non-specific addresses. Constant Contact assumes that such addresses do not belong to a single individual.
