How to add IP address to blacklist or whitelist for Gmail
Did you receive multiple emails on Gmail from a single source, despite unsubscribing from their mailing list? One of the best ways to block spam from unwanted senders is to put their IP address on the blacklist. Similarly, you can put an IP address into the whitelist (whitelist) so that it will not be blacklisted. This is useful if some of your important email sources are regularly in the Spam folder .
Follow the methods below to put a certain IP address into the whitelist or blacklist for Gmail. While the blacklist shown here is specific to Gmail, one of the techniques for whitelist has a more universal application. It will remove an IP address from many services in the blacklist.

How to add IP address to blacklist for Gmail
Because you are not authorized to access your mail servers, Gmail has no mechanism to block incoming emails based on IP address. To do this, you will need a third party service, such as Block Sender . It is available as an extension for Chrome / Edge or Firefox.
After the extension has been added to the browser, log in to Block Sender with your Gmail account.
Click New Block on the Block Sender dashboard.
In the next step, you will see an option to block email senders based on IP address. You can decide whether future emails from this source will be delivered to Trash or deleted directly. This special service (blocking email sources by IP address) is only available with paid Plus or Pro packages.You will see an option to block email senders based on IP address
Some spam sources do not maintain a permanent IP, but instead attack from new IPs, designated over a range. To block them, Mailstrom is a useful service. It lists all emails from one source and when you click Block , the tool determines the range of IP addresses, among many other things, and ensures that any email from this range in the future will do not show up in your inbox anymore.Mailstrom

Adding IP addresses to the whitelist takes more time than the blacklist process, because there are many email filtering services associated with webmail accounts. In case your email is classified as spam by Gmail servers, you will get error 550. Google has a specific sender form to help you ensure the ability to send mail to Gmail users. Reference at:

There are two common web services to check if you are faced with this problem. These are MultiRBL (http://multirbl.valli.org/) and MxToolbox (https://mxtoolbox.com/blacklists.aspx). The second tool puts the IP address used in the previous section into the whitelist as shown below. The service put the IP address on the correct blacklist specified.
