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 |
| Hotmail/MSN | Yes | No |
| Juno/Netzero/UnitedOnline | Yes | Yes |
| Mail.ru | No | No |
| Mailtrust | Yes | No |
| Outblaze | Conditional | Conditional |
| PA.net | No | No |
| RoadRunner | Coming Soon | No |
| USA.net | Yes | No |
| Yahoo | Yes | Yes |
Outblaze’s conditions are that you are only sending confirmed opt-in email across all of your IP space. They only provide FBL emails to senders on their whitelist.
RoadRunner is currently publishing “early 2009” for when their FBL will go live. Senders who have a current FBL will need to reapply when the new FBL goes live.

Hi Laura,
United Online does have a feedback loop, we receive it at work. From what I recall it’s part of the UNTD Trusted List on their postmaster page.
Cheers,
Matt

Fixed!
Laura,
Correct me if I’m wrong, but doesn’t USA.net provide the FBL for verizon?
Thanks!
Jared
Laura-
The URL for the Yahoo! FBL is listed as http://http//postmaster.yahoo.com – you’ve got an extra http// in there.

Fixed that, too.
I hadn’t heard of Verizon and USA.net teamed up. I’ve got a question into Verizon to see.
[…] The same goes for Feedback Loops – not all ISPs will tell you when a subscriber marks an email as spam. For a handy list of ISPs that do and do not offer whitelisting and/or feedback loops, see this blog post at Word to the Wise. […]
Laura,
I love that you posted these, great reference table. May I suggest you link FBL/Whitelist and Postmaster help pages separately, as for the ReturnPath administered ones, they can differ from the main postmaster sites as in the case of Yahoo. I linked up the FBL’s in my recent column http://www.clickz.com/3632514
Hi, Stefan,
There are bigger plans for the information but this is just an easy way to present the data right now.
Minor but important correction: Return Path doesn’t “administer” feedback loops. We host ’em for our ISP partners, providing the necessary technology & advising when asked — but the ISP owns the feedback messages and makes all the decisions.

[…] like BlastWizard can tell you how many complaints you got for a certain email job. Check out this blog post for a list of ESPs that offer feedback […]
Laura,
Roadrunner also has feedback loop. Here is that link.
