In the past, if you didn't want to use our email to send submission emails, you could only change the sending email address by using custom SMTP in the form.
Now, our app can send submission emails using your own Mailgun account. This way you can use your domain name to send emails to enhance your brand trust.
You can follow these steps to change the sender of the submission email to your Mailgun email address.
