If you want to use webhooks in your scenarios, you need to set a URL for each type of webhook in the Webhooks section of the Mailgun control panel.
For more information, please read the Webhooks section.
If you use sandbox (if you haven't set up any domain) and want to send emails, you need to verify recipients' email addresses in your Mailgun account's settings first.
For more information, please read the Mailgun documentation.
If you send emails from a verified domain, the email address of the sender must include this domain. If you use, for example, a domain @example.com, you can set up firstname.lastname@example.org ( but not email@example.com) as the sender email address.
