Safelisting IP Addresses for Lead Gen & CRM Emails

Article: 000050494
Updated: March 24, 2025

Safelisting ensures the emails you send with Lead GEN & CRM land in the inbox. When safelisting an Internet Protocol (IP) address within the email client, the sender from that IP address is identified as a trusted source by the mail server.

This helps to ensure that emails being sent are placed into the inbox and not in the spam folder.

You may want to safelist Lead Gen & CRM IP addresses in your own email client if you are sending emails to yourself for testing. Agencies and companies may need to work closely with clients to safelist Lead Gen & CRM IP addresses so that clients receive their intended emails. 

This article will provide information on safelisting IP addresses.

The Purpose of Safelisting

Email providers filter incoming emails in many ways. You can have more control over the emails that are sent to your email address through safelisting and blocklisting.

A blocklist is a list of IP addresses or domains that you do not want emails from.

A safelist is the opposite—it is a list of IP addresses or senders that you know are not sending spam emails. Your IT team can add IP addresses to your safelist to allow emails sent from known senders to always appear in your inbox. This benefits you if you are constantly testing email sends and are actively testing emails in Lead Gen & CRM.
 



Safelisting Across Email Providers

The safelisting process differs between email providers. Refer to your email provider's associated help documentation for information on safelisting on your client of choice:
