In this article, you will learn what a technical sender domain is and how to align it with your sender domain. Thanks to this setting, the emails you send will appear to the Mailbox Providers as coming from your sender domain, rather than from a magnews domain.
This configuration is advanced and recommended for users with technical skills.
What is the technical sender domain
The technical sender domain is the Return-Path domain, also known as Mail From, Envelope From. It is an essential domain for the delivery of emails:
- it is the domain for which the SPF record is configured and where the SPF check is performed by the Mailbox Providers;
- it is the Return-Path email address domain to which the Mailbox Providers send bounces that are then processed, classified, and displayed in your Magnews account;
- it is the domain that is identified by the Mailbox Providers as the server sender the emails.
This domain is managed by Magnews and, if not customized, is a subdomain of magnews.net.
Usually, it is hidden and not visible to the contact. For example, Gmail shows it as a "mailed-by" domain in a dropdown menu visible by clicking on "to me" under the sender of the received email.
The technical sender domain may not match the sender domain, which is the domain of the email address visible to the email recipient and identified as "from". This does not negatively affect the deliverability of your emails.
Why align technical sender domain and sender domain
By configuring the technical sender domain, the emails you send will appear to Mailbox Providers as coming from your sender domain or its subdomain, rather than from our subdomain of magnews.net.
Aligning the technical sender domain and sender domains is a winning strategy for your email communications, from different perspectives:
- Improved Brand reputation: your communications will appear to come exactly from where you say they come from, thus strengthening the trust of recipients and Mailbox Providers in you;
- Improved Email deliverability: recipients and Mailbox Providers will see your emails as reliable and legitimate, not classifying them as spam;
- Improved Brand Protection: thanks to this configuration, you can meet SPF alignment, a condition recommended by DMARC to strengthen the protection of the sender domain from unauthorized use, such as spoofing and phishing.
How to configure the technical sender domain
Access the Sender Domains list, from Settings then Brand Protection.
Click on the sender domain for which you want to configure an aligned technical sender domain.
In the Summary tab, the section related to the technical sender domain now appears, so click the Configure button to select the type of technical sender domain to set up.
Select the type of technical sender domain you want to set up
As a technical sender domain, you can set up:
- Subdomain of the sender domain: recommended choice. If the sender domain is example.com, you might set up send.example.com;
- Sender domain itself: advanced configuration and recommended only if the sender domain is already a subdomain of the corporate domain.
In both cases, ensure it is exclusively reserved to magnews and is not already in use for sending emails from other systems, to avoid conflicts or interruptions in the email flow.
Select Magnews Domain to continue using the magnews technical sender domain.
Subdomain of the sender domain
Select the first option Subdomain of sender domain and write the subdomain in the Subdomain field.
Share the provided instructions with the IT area that manages the DNS configurations of the sender domain.
Before proceeding, ensure that the chosen subdomain is exclusively reserved to magnews and is not already in use for sender emails from other systems, to avoid conflicts or interruptions in the email flow.
Sender domain itself
Select the second option Sender domain (advanced).
Share the provided instructions with the IT area that manages the DNS configurations of the sender domain.
Before proceeding, ensure that the sender domain is exclusively reserved to magnews and is not already in use for sending emails from other systems, to avoid conflicts or interruptions in the email flow.
Configure the DNS records provided in the instructions
Ask your IT area or hosting provider of the sender domain to add the DNS records of type MX and TXT provided in the instructions that appear after selecting the type of technical sender domain.
Specifically, the DNS records to create are:
- MX record, for the correct reception and management of bounces;
- TXT record for SPF, an email authentication technology that defines which IPs are authorized to send on behalf of the domain.
Activate the technical sender domain
After correctly configuring the MX and TXT DNS records for the chosen technical sender domain, go to the Summary tab of the sender domain, under the section Technical Sender Domain, and click the Activate technical sender button.
Well done! The sender domain and technical sender domain are now aligned.
