I have posted a ISP Information Page. Right now it contains links to Postmaster pages, Whitelist signup pages and FBL signup pages. I have some ideas on what information would be helpful to add, but would like to hear what types of info people would like to have easy access to.
What do you think I should add to the page?
I’ve been working on some reference information about ISPs for my own internal use as well as sharing with clients. There doesn’t seem to be any public reference site for postmaster sites, so I decided to publish what I’ve collected. ISP FBL Whitelist AOL Yes Yes ATT No No Bellsouth No No CANTV.net No No Charter.net No No Comcast Yes No Cox Yes No Excite Yes No Frontier No No Gmail No No...
A number of ISPs have email information and postmaster sites available. I found myself compiling a list of them for a client today and thought that I would put up a list here.
