You can associate your Organization with one or more Internet domains that you own. This allows you to invite your employees, via their company email addresses, to the Organization. This lets you treat ownership of one of your company email addresses as a sign of trust.

To add a domain to your Organization, you first need to verify that your own it. You do this in the Admin Center’s Domains section, which also lists the domains you have already added, if any, and those currently being verified:

Add a domain

1. Visit the Console and sign in.
2. Navigate to Admin Center > Domains.
3. Click the Add Domain button.
4. On the Verify Domain page, enter your company’s domain name then click the Save & continue button:
   

   

5. Now choose a verification method. You have two choices:
   • Update your domain’s DNS record with a TXT resource record. The Verify Domain page will present a text string containing a unique token to use as the body of the record. You will need to visit your domain registrar to add this string to your DNS record:
     

     

   • Upload an HTML page file to your website’s root directory. To use this option, your site must be accessible via HTTPS. When you select this option, the Verify Domain page presents a Download HTML File button — click this to get the file you will upload to your own site. The file contains the same token used for the DNS record option:
     

     

6. Click the Verify Domain button.
7. Upload your HTML file or update your DNS records.

Twilio checks your DNS record or uploaded file immediately, but because DNS records can take up to 72 hours to propagate — usually it’s much quicker than that — you may not see your domain marked as verified straight away if you have used this method.

In any case, Twilio re-checks the file upload or DNS data every 24 hours to confirm your continued ownership. If the token gets altered or removed, an Organization’s Owner or Administrator has 30 days to re-validate the domain before it is automatically deleted from the Organization. Until the domain is re-validated, you will not be able to use email addresses from that domain to add new users.
