It’s likely that you are reading this because Google have blocked your IP address as they have identified your IP address as a source of spam emails. So, basically, you can’t send email to any Google accounts.

First things first. Why did Google blacklist you?

Google don’t do this lightly. You have either been sending large amounts of email to Google accounts over a short period (in which case stop it!) or more likely you have some MalWare on one of your PCs that is doing this without your knowledge.

So before we look at how to request you are removed from the blacklists make sure you scan all of your PCs and servers for any unwanted software and remove it. If you request removal before you do this you are just going to end up blacklisted again in the next few hours.

So, how do I remove my IP address from Gmail’s blacklist?

Firstly, make sure that you are on the blacklist. The tell tale sign is in the rejection email you get from Gmail. Look for a message like the following:


[your ip address] Our system has detected an unusual rate of unsolicited mail originating from your IP address. To protect our users from spam, mail sent from your IP address has been blocked. Please visit to review our Bulk Email Senders

Gmail blacklist messages usually start with a 550 error. If you don’t see this you may have another email delivery problem that needs investigating.

Once you have confirmed that you are on the blacklist you can put in a request to be removed. The link to do this can be found under “My domain is having delivery problems with GMail”.  It is good practice to go through the questions on the help pages to make sure that you have followed correct procedure before requesting removal. If you are sure you have done everything necessary to remove any MalWare and improve your security then you can go straight to the Report a delivery problem between your domain and Gmail link.  Google get hundreds if not thousands of these requests a day so make sure that you provide all the information that they ask for and it won’t hurt to thank them in advance in the additional information section.

Once you have requested help from Google sit back and be patient – it’s not a quick process as these requests are likely to be handled manually by Google. It is also quite likely that you will never hear from Google about your request for removal even though they will be working on it.

If after doing this you still cannot send email then you may need to bring in some professional help to resolve the situation.
