Marketing Cloud Engagement tracks IP addresses used to log in to your accounts over the past six months and provides recommended ranges for your allowlist. After you review the suggested ranges, add IP ranges to your allowlist with a few clicks.
Where: This change applies to all Marketing Cloud Engagement editions.
When: This change became available on July 30, 2026.
In a future release, all Marketing Cloud Engagement accounts are required to use the login IP allowlist to block all unrecognized logins. Before this requirement takes effect, use this feature to populate your allowlist. We notify you by email when an enforcement date is determined for your instance.
How: Log in to your parent enterprise account as a Marketing Admin. In Setup, on the Login IP Allowlist page, review the recommended IP ranges. Select the ranges to add, and then click Accept Selected.
