Twilio SendGrid subuser accounts can authenticate a domain within the subuser account or obtain a verified domain from their main (parent) account. This article will explain how parent accounts can assign their verified domain and dedicated IP to their subuser (child).
For information on subuser creation and best practices for subuser accounts, check out our documentations below:
Assigning a verified Domain Authentication domain, Link Branding domain and Dedicated IPs to an account’s subusers, allows parent accounts to easily manage and organize their email sending through different domains and IP addresses.
Parent accounts can assign only one domain for each subuser. If subuser needs more domains, they can verify domains within their account.
Also parent accounts must assign at least one dedicated IPs to their subuser before the subuser can send any emails. When a subuser is assigned a dedicated IP, this subuser’s emails will only be sent from the assigned dedicated IPs. Parent accounts can assign as many dedicated IPs to any subuser.
If an assigned dedicated IP is set up for rDNS, customers will want to ensure that the subuser with the assigned IP, intends on sending with the domain configured for rDNS on that same IP . And also has the same Domain Authentication and Link Branding domain assigned.
Customers can assign verified Domain Authentication, Link Branding and IP addresses by clicking “Change Sending” button in the Subuser Management page when editing a subuser. Then select the available domains within the drop down menu or list of available dedicated IPs.
Below are some screenshots of the Subuser Management page that show where customers can assign Domain Authentication, Link Branding and IP addresses to their subuser.
