From Domain Authorization - Configurator

Domain From Authorization

  1. Log in to the EmailLabs panel.

  2. Select the 'Administrator' tab from the left menu, then go to the Sender Authorization section.

  3. Choose the 'Add Domain' option located on the right side.

  4. Choose the subaccount for which you want to authorize the domain.

  5. In the 'From Domain' field, enter the domain from which email messages must be sent and authorized. The domain should be added to the form in the format: Note! If you are concerned about changing the DNS settings of your From domain, we suggest using a subdomain.

  6. Proceed to advanced settings.

  7. In the 'DKIM Selector' field, place the selector with which you will label the DKIM record in your domain, e.g., 'plpl'. The maximum length of the selector can be 7 characters; you can use both numbers and letters. The selector is the label used to search for the DKIM key in DNS records.

  1. The 'Tracking Subdomain' field pertains to the subdomain that will be used to create individual Link Tracking instead of the default EmailLabs domain. The suggested phrase 'click' will be added to the authorized From domain name, e.g.,

  2. If you want to manage settings and collect data related to open tracking without link tracking, you can do so in the following section: SMTP Accounts > Settings > Open tracking / Link tracking

Attention! This record is responsible for collecting information about tracking link clicks and message opens. Make sure you want to use this functionality. If you have previously implemented sender authentication correctly and want to start using the Link Tracking feature, verify that you have both data collection options enabled in the following sections:

SMTP Accounts > Settings > Open tracking / Link tracking

Remember that if you have added a tracking record in the past and want to opt out of it, previously used links in the message will remain active if the CNAME record responsible for tracking is still visible in DNS. The requirement is only to disable the tracking settings in the EmailLabs panel.

Configuration of the Subdomain for the Return-Path Address

  1. The 'Return Path Subdomain' field pertains to the subdomain that will be used to create an individual Return Path. The suggested phrase 'mailing' will be added to the authorized From domain name, e.g.,

DMARC Record Set-Up

  1. The 'DMARC Policy' field pertains to the rule that determines what should be done with an email message when it fails DMARC authentication. Choose the appropriate policy.

  2. In the 'Percentage' field, enter the appropriate parameter that informs email providers about applying the DMARC policy only to a percentage of messages that did not successfully pass verification. Note! This will not work for the 'none' policy, only for 'quarantine' or 'reject.'

  3. In the 'RUA Email Adress' field, enter the email address to which aggregate reports (rua) about attempts to deliver email messages from the given domain will be sent.

  4. Click 'Save.' Wait for the EmailLabs system to generate 4 records that need to be added to the control panel of your domain hosting (DNS).

After generating records and adding them to DNS, please inform Customer Service at so we can switch your sendings to the new authentication method. Otherwise, sent messages will not be properly secured with previously configured authentications. Failure to meet the requirements of email providers may result in the rejection or incorrect classification in the inbox.

  1. If you are the domain administrator, enter the generated records into DNS. Otherwise, contact your hosting provider to add a CNAME record to your From domain. The authorization entry has three elements: Domain, Record Type, and Value. Each hosting provider has its own rules for DNS management (some may require adding a dot at the end, for example).

  2. Changes in the domain settings. Depending on the TTL in your hosting, propagation may take from 15 minutes to 24 hours.

  3. Return to the EmailLabs Dashboard and click the 'Check' option to check the authorization status.

  4. The authorization has been successfully completed if the status changes to ‘Accepted.’ Now you can send emails using all addresses set on the authorized From domain.

Note! If you are not sure how to fill in these fields correctly, contact Customer Support at
