Sandbox Domain Authorization Error

In the Interfacing Sensors over VPS module, under the Introduction to Mailgun section, in step 6, I am unable to create a receipt as it is showing me a message “Sandbox domains are restricted to authorized recipients only.” I have verified my account. Can someone please help me with this? I have attached a screenshot for reference.

Hi @nimisha.bhagat29,

  1. Ignore the warning message Sandbox domains are restricted to authorized only.
  2. Next, enter your email id email address box and click on Save Recipient.

Do let me know in case you need further assistance.

In the right-hand side of the screenshot you’ve posted, there is a text box to enter your email. Enter your email there, then click on “Save Recipient”. After this, open your email, you’d have gotten an email from Mailgun which would ask you for receiving emails from Mailgun. Click on the link in the email, click on Activate on the page that gets opened and your email would be verified as a recipient on your Mailgun domain. Refresh the page and it would show your entered email as verified.
