Assign authenticated domains to subusers

Objective

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). 

Product

Twilio Sendgrid Email

Procedure

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 from the UI, customers can assign up to 5 verified domains to a subuser via API through our Associate an Authenticated Domain with a Subuser (for up to Five Domains) endpoint. If the subuser needs more domains, they can also verify domains directly within their account.

When a subuser is assigned a dedicated IP, this subuser’s emails will only be sent from the assigned dedicated IP. 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 navigating to:

Settings > Subuser Management > Choose the subuserChange Sending button to the right of Domain Authentication/Link Branding.

Here, you can select any available domains within the drop-down menu.

Also note that Dedicated IPs and Link Branding may also be assigned in this same area by selecting the IP you wish to assign to this subuser.
