You can do this by simply opting for a difficult password and keep changing it regularly. Updating CMS and Plugins also helps you avoid being blacklisted, especially if you are using WordPress.

Hopefully now you are clear about how you can avoid being blacklisted. So let us move on to understanding how your IP can be removed from the Gmail blacklist. The common error codes reflected on failed mail delivery are 421 and 550 errors.

While 421 errors are often temporary blocks, 550 errors are permanent failure. In case of 421 errors, email servers attempt to resend the emails. If without any loss of time you correct the spam or email flood issue, then these blocks can be resolved automatically. On the other hand if left unchecked Google may decide to block your email entirely.

The logs of 550 errors, which are permanent failures, often include links and additional information. In case of 550 errors you will have to take some action before Gmail removes your server IP address.
