SPF(supported)
DKIM(recommended)

This article covers the SPF and DKIM authentication processes for 123FormBuilder and how they are managed in Valimail. While only one of the two authentication methods is required for an email to pass DMARC, our recommendation is to configure both whenever possible.

Configuring DKIM authentication for your 123FormBuilder emails

Own an Enterprise Account and purchase the DKIM add-on

First things first, for DKIM (Domain Keys Identified Mail) to work:

  • you need to have an Enterprise account and purchase the DKIM add-on, if you are interested in this get in touch with our sales team;

  • custom email domains used as sender or from emails need to have properly configured SPF records;

  • a new TXT record needs to be created in your organization’s DNS;

  • the setup needs to be validated on our side after the DNS is updated;

When editing your forms, you need to navigate to the “Emails” section. In the left side panel, you directly have the orange banner with “DKIM. Interested? Get in touch ->”.

Emails section

Another option would be to click on “Show From and Reply-to options”. Then you will see: and click on “Show From and Reply-to options”. Then you will see:

  • a dropdown that allows you to select a “From email” – which will appear as the sender of the email notification;

  • and two options displayed above this dropdown – Add email & Enable DKIM.

Enable DKIM

If you don’t want the sender of your email notifications to be [email protected] or [email protected], but want to use an email from your own domain instead, based on the desired level of security you can either:

  • Click on Add email and configure SPF records for your organization’s domain;

  • Or click on Enable DKIM and include a DKIM signature to your email notifications, as an addition to the SPF records (which are mandatory for all custom senders).

If you already paid for the DKIM add-on, clicking on Enable DKIM will allow you to choose from two options:

  • Add the DKIM signature to a custom domain for which you already configured the SPF records;

  • Or, add a new email and configure SPF & DKIM in the same step.

DKIM setup

If you want to add a DKIM signature to an email domain that already has SPF records configured, you just need to select the desired email & click on next.

Enable DKIM, and select an email

Then you will see a pop-up with DKIM setup details:

  • copy the DKIM selector & key, and create a new TXT record with these details in your DNS;

  • close the pop-up and wait for the DNS to update;

Enable DKIM, add selector and key to a TXT record in your DNS

After the DNS is updated, come back to the form, click on Enable DKIM button again and validate the setup. If the setup is valid you will see a success message and will be able to use this email address as the sender for upcoming email notifications. Don’t forget to save the setup once you are done customizing the email.

After DNS is updated, get back to Enable DKIM to validate the setup

SPF & DKIM setup

If you want to add a DKIM signature to an email domain that doesn’t have SPF records configured yet, click on Enable DKIM, and instead of selecting an email from the list, click on add new email.

Enable DKIM, and add new email

Then you will see a pop-up where you can type the desired email.
