What do I do if I'm added to a deny list?

Ending up on a deny list can be detrimental to your domain’s email deliverability. These days, there are hundreds, maybe thousands of deny lists out there. Some, like the Spamhaus SBL, can bring your email program to a screeching halt. Others are little more than an annoyance. Many of the world's largest inbox providers use deny lists to help them make inboxing and filtering decisions. Others rely only on their own internal metrics. Always remember: if a listing service ever asks you pay a fee for a delisting request, or if they say that they do not accept delisting requests, then you should not waste your time trying to get your domain/IP delisted because these services are rarely, if ever, used. However, if you find that your IP address has been added to a deny list by one of the many legitimate services, then submitting a delisting request is the top priority. Depending on the level of your account, you should approach being added to a deny list in one of 2 ways:

Shared IP Plans (Free, Legacy Lite, and Essentials)

Spamhaus deny list

If you are on one of our shared IP plans and you notice a block message from Spamhaus based on one of our IP addresses, please know that we are already working Spamhaus directly to address the issue. There is no need to make an additional request through our support team.

Other deny lists

If you notice a block message from a service other than Spamhaus based on one of our IP addresses, please contact support. We will handle all delisting requests for our shared IP users.

Dedicated IP Plans (Pro and Premier)

We ask that our dedicated IP plan users make the initial delisting request in the event that they discover their SendGrid IP on a deny list. These IP addresses are only assigned to one account at a time, so we expect those users to take responsibility for all of the mail that is sent through their account. SendGrid will still be happy to step in and assist with these delisting requests if the listing service requires the IP administrator to take action, or if the delisting form is too complicated.

In the event that a sending domain (and not the IP address) is added to a deny list, the domain’s controller will be responsible for handling the delisting request.

Checking Your IP Address

Here are 2 aggregation websites that anyone can use to check on the status of their IP:

Delisting Request Forms

Below are links to the delisting forms used by the more popular external deny listing services:

If you request a delisting from a deny listing service, and don't do anything to change the behavior that caused the listing in the first place, it is likely to occur again. Depending on the list, it can be progressively harder to get delisted after the second or third listing.

Don't delist from major deny lists without a plan in place to address the issue that caused the listing! Learn more about how to avoid and mitigate risk of being added to a deny list here.
