The SMTP feature is available for the Gold plan or higher. With this feature you can send notifications on submissions without the address email@example.com appearing as the sender in the body of the email.
1. Go to the Settings → Notifications section of your form and in the left-side panel, under the Options subsection tick Use your own SMTP server. Next click on Set up SMTP server.
2. In the new lightbox window, insert the Host, Port, Username and Password of your SMTP server, select the Protocol your server uses, hit Test connection and a code will be automatically sent to your email address.
Note: For Gmail, you can either set the protocol on Auto or SSL.
3. Once you have acquired the code, copy it and paste it in the verification code box, back in 123FormBuilder. Click on Validate and changes will be automatically applied in your notification settings. From now on, all notifications will be sent through your SMTP server, namely, the sender will no longer be 123FormBuilder, but the email address you have assigned in SMTP Options.
Open up the SMTP settings and double check that the SMTP connection is enabled.
Note: Notifications will be sent through your SMTP server only if they are in HTML format.
