Yesterday I talked about GFI responsiveness to queries and delisting requests about SORBS listings. Today I’m going to look at data accuracy.

Delivery Monitor Closing Down

Delivery Monitor by Aweber is one of the inbox monitoring services available for senders. Aweber has been in the process of winding down Delivery Monitor for the last few months and they will be turning the service off completely tomorrow.
A lot of folks have asked me about replacements for Delivery Monitor. There are, of course, Return Path and Pivotal Veracity, but many of the smaller mailers I talk to can’t justify the expenditure for either service.
