How to add a custom sender address to an email notification

Setting up notifications in 123 Form Builder is an easy process and we offer multiple customization options.

By default, we send email notifications from noreply@123formbuilder.com. In this article, you will learn how to send emails using your own custom domain email.

Open the notifications section of your form and expand the From and Reply-to options menu.

Custom email

Here you have three options available:

  • Add custom email
  • noreply@123formbuilder.com (default option).
  • noreply.myfor.ms

When you connect your SMTP server at From email you can’t change anything. The form automatically prefills the SMTP email sender.

We incorporated an SPF email authentication tool for the custom email option to ensure that only authentic domains/users send email notifications.
We want to avoid spam emails, email bounce-backs and to prevent any phishing attempts that are pretending to be a legitimate business.

With this authentication process, you will grant 123 Form Builder permission to send email messages on your behalf.

To accomplish that, create an SPF record in your DNS. Click on this guide to find out more details about this subject and obtain our SPF record.

After configuring the SPF record, at From Email choose Add custom email.

Type in your email domain.

SPF record

Click Add. Our system checks the email domain and an error message shows up if your email domain isn’t set up properly.

verify custom email

The custom emails added can be used on the same form in all your email templates.

Important Note: The configuration must be done on each form. This setup isn’t made at the account level. For newly created forms you will have to add the custom email again.

Secondary, with the noreply.myfor.ms option you can remove any reference to our domain, 123 Form Builder. Simply select it from the dropdown menu and you’re done. This option is available if you have purchased a paid subscription. Visit our Features Matrix for more details.

In order to send emails though your own SMTP server simply follow this guide.

Important note!

  • Forms with our previous notifications version can define a custom sender only by enabling the SMTP feature.
  • If you are a white label user, at From email you have a fourth option available: noreply@whitelabeldomain.com.
