The mailgun settings are only necessary if you want to use your own mailgun account. If you leave them blank it will use the default w3apps.co account. If you are experiencing any issues with the emails or want to have additional controls. Before you can add Mailgun to the app, you will need to create a Mailgun account at www.mailgun.com. If you have any questions during or about the Mailgun account setup, please reach out to the Mailgun support team as they are more familiar with their service.
After setting up the mailgun account, locate the following that were created in the setup; mailgun domain, mailgun "from" email, and the mailgun API key. These items will need to be copied and pasted into the app on the settings page.
Once added click Save. Be sure to send a test email to yourself to insure the settings are correctly implemented and working.
Do not include www or http://. For example "domain.com" is acceptable, but "www.domain.com" is not.
Mailgun "From" Email
The email that shows as the from address when emails are sent. Needs to be at the same address as the mailgun domain.
