Blacklist Monitor: know when your domain or IP is listed
We check your domains and sending IPs against email blacklists on a schedule and alert you by email, so you can act before a listing hurts your campaigns.
Add a domain or IP, choose who receives the alerts and you are done.
What is an email blacklist?
An email blacklist, or blocklist, is a list of IP addresses and domains associated with spam or abuse. Mailbox providers and spam filters consult these lists when deciding what to do with a message, so a listing can send your email to spam or get it rejected, even when your content is fine.
IP blacklists
List the server addresses that send email. They affect everyone using that IP, which matters on shared sending infrastructure.
Domain blacklists
List domains found in spam messages or links. They follow your domain even if you change sending platform.
Why monitoring matters
Listings can happen without warning. Finding out early shortens the time your campaigns are affected.

You choose what to watch and who should be told. The monitor repeats the checks automatically.

What to do if you are blacklisted
A listing is fixable. Find the cause first, because a removal request without a fix tends to end in a new listing.
| Situation | What it usually means | What to do |
|---|---|---|
| IP listed | The server sent spam-like traffic, or shares reputation with others. | Ask your sending platform for a clean IP, then follow the list’s removal process. |
| Domain listed | The domain appeared in spam messages or links. | Find the source, secure your accounts and sending, then request removal. |
| Listed after a campaign | The list may include old or purchased addresses. | Verify the list, remove inactive contacts and only then send again. |
| Not listed | No action needed on the monitored lists. | Keep monitoring, and check placement and authentication if results still drop. |

Blacklist Monitor FAQ
-
What is blacklist monitoring?
It is the automatic, repeated checking of your domains and IPs against email blacklists, with an alert when a listing is found.
-
Are IP and domain blacklists different?
Yes. IP lists concern the server that sends the email, while domain lists concern the domain in the message or its links. It is worth monitoring both.
-
How often are the checks?
Every 12, 10, 8 or 4 hours, depending on the plan.
-
Do you remove me from a blacklist?
No. Each list has its own removal process. The monitor shows the listing and alerts you, and the guide above explains how to approach it.
-
Does a listing always mean my email is blocked?
No. Each provider decides how much weight to give each list, but a listing is a risk worth investigating.
-
Which plans include it?
All deliverability plans. The number of monitors and the scan frequency depend on the plan.
