Step 1 - Understand why you need whitelisting
It is very useful to understand why whitelisting is necessary for your organisation.
The short articles below explain the reasons behind it, and contain useful information to be used during your whitelisting process.
If you are familiar with how whitelisting works, feel free to move onto the next section.
Step 2 - Whitelist Phishing Tackle in your mail environment
Below you will find all the guides necessary to whitelist our servers within your mail environment.
If you do not see your mail environment below, please contact support and we'll help you get set up.
As we mention in the previous guides: We recommend whitelisting our IP addresses or hostname in your mail server if you're not using a cloud-based spam filter. If you are using a cloud-based spam filter, you will need to whitelist by email header in your mail server and whitelist by IP address in your spam filter.
