Blackist Delisting Guide: AOL

AOL's mail system has run on shared infrastructure with Yahoo since 2018, so a listing that blocks your mail to AOL addresses is, in practice, a Yahoo listing.

The fix is the same for both. Below is the current process, plus a few things worth knowing before you start, since AOL changed ownership again in early 2026 and it is worth double checking the live process directly if anything here looks out of date.

Which domains does this actually affect

AOL's blacklist does not only affect aol.com addresses. Because of the shared infrastructure, mail to any of the following domains can be affected by the same listing: aol.com, aim.com, verizon.net, and a handful of older AOL owned domains still in use.

If you are troubleshooting bounces to any of these and have not checked AOL specifically, it is worth doing so even if the recipient address does not end in aol.com.

Why AOL's blacklist is really Yahoo's blacklist

AOL and Yahoo merged their mail infrastructure starting in 2018, and by 2019 the migration was complete. Since then, mail sent to AOL addresses is filtered through the same systems Yahoo uses, not a separate standalone AOL system.

This is why older guides that point to a standalone AOL Postmaster form can be outdated. The practical result is that fixing a Yahoo listing and fixing an AOL listing are the same task.

One more thing worth knowing: AOL changed ownership again in January 2026, moving from Yahoo to a company called Bending Spoons. It is not yet fully clear whether this affects the mail infrastructure or delisting process itself.

If any of the steps below do not match what you see when you actually go to act on this, that ownership change is the most likely reason, and it is worth confirming the current process directly rather than assuming this guide is still exactly right.

Step by step: how to get delisted

1. Check Spamhaus first. Yahoo and AOL's filtering relies in part on Spamhaus data, so a listing here may actually trace back to a Spamhaus issue. See our Spamhaus delisting guide if that is the case, since fixing it there can resolve the AOL and Yahoo listing too.

1. Find and fix the underlying cause. Spam complaints, a compromised server, or missing email authentication are the most common causes. See the section below for details on each.
2. Sign up for the Complaint Feedback Loop (CFL) if you have not already. This gives you visibility into complaints as they happen, which both helps you catch problems early and is often expected as part of good sending practice by mailbox providers like Yahoo and AOL.
3. Submit a Sender Support Request through Yahoo's postmaster tools. This is the current path for requesting review of a listing, rather than a standalone AOL specific form.
4. Wait for review. As with most providers, a request submitted before the underlying cause is fixed is unlikely to succeed, and may need to be resubmitted later.

Why IPs get listed here

Spam complaints. This is the most common cause. If enough recipients mark your mail as spam, the shared Yahoo and AOL system takes notice, even if your overall complaint rate is small in absolute terms.

A compromised mail server. If your server or a website on your IP is compromised and starts sending spam without your knowledge, this system will flag it the same way it would flag deliberate spam.

Shared IP problems. If you are on shared hosting, another sender on the same IP or range can cause your mail to be affected too.

Missing email authentication. Weak or missing SPF, DKIM, or DMARC records make your mail more likely to be treated as suspicious in the first place.

How long does it take

There is no fixed timeline published for this process. In practice, requests where the underlying cause has clearly been fixed tend to move faster than requests where the issue is still ongoing or unclear.

How to avoid getting relisted

Keep your complaint rate low, make unsubscribing easy, and keep your authentication records (SPF, DKIM, DMARC) correctly configured. If you recently increased sending volume, ramp up gradually rather than sending a large volume all at once.

Frequently Asked Questions

Is the AOL blacklist the same as the Yahoo blacklist?

Effectively yes. AOL's mail infrastructure has run on Yahoo's systems since 2018, so a listing affecting AOL addresses is handled through the same process as a Yahoo listing.

Why do I see bounces to aol.com and other addresses at the same time?

Because several domains, including aim.com and verizon.net, share the same underlying mail infrastructure as AOL. A single listing can affect mail to more than one of these domains at once.

Does checking Spamhaus help with an AOL listing?

It can. Yahoo and AOL's filtering relies in part on Spamhaus data, so an AOL or Yahoo listing sometimes traces back to a Spamhaus issue that needs to be fixed directly.

Has AOL's delisting process changed recently?

AOL changed ownership in January 2026. It is not fully confirmed whether this changed the delisting process itself, so it is worth verifying the current steps directly if something here does not match what you see.
