Employee Newsletter: Add a Custom Sender Address

■

Overview

If you want to customize the ‘from’ email address of your newsletters, so that they are not sent from [e-mail] ([e-mail] for EU customers) by default, you will need to follow the steps below.

Simpplr uses AWS SES for sending email. Adding an MX record is mandated by SES if you want to use Custom Mail from domain. 

Why add a custom Mail from domain?

You might choose to use your own Mail from domain to give you more flexibility in complying with Domain-based Message Authentication, Reporting and Conformance (DMARC).

Messages that you send through Amazon SES automatically use a subdomain of amazonses.com as the default Mail from domain. Sender Policy Framework (SPF) authentication successfully validates these messages because the default Mail from domain matches the application that sent the email—in this case, SES.

If you don't want to use the SES default Mail from domain, and would rather use a subdomain of a domain that you own, this is referred to in SES as using a custom Mail from domain. To do this, it requires you to publish your own SPF record for your custom Mail from domain. In addition, SES also requires you to set up an MX record so that your domain can receive the bounce and complaint notifications that email providers send you.

Note:

Adding a custom sending address requires access to the DNS settings of your desired domain. You will not be able to complete the verification of your new sender address without access.

Add sender address

1. Go to Manage > Application > Setup > Newsletter. Click Add domain. When entering a sender domain, we recommend calling it newsletters.<yourdomain>. Click Add when finished.

2. A modal will open with the DNS records that need to be added. Send the domains and records to your IT department.

Updating both MX and TXT records is necessary to:

1. • Authenticate the custom sender address: Ensuring that emails sent from the custom sender address are verified and trusted by recipient mail servers, reducing the risk of being marked as spam.
     
   • Improve email deliverability: Properly configured MX and TXT records improve the chances of your emails reaching the intended recipients’ inboxes, as many email providers check these records to fight spam and phishing.
     
   • Protect domain reputation: Ensuring that only authorized servers send emails on behalf of your domain helps maintain your domain’s reputation and prevents misuse by spammers.
     
   • Enable proper email routing: MX records ensure that incoming emails are correctly routed to the appropriate servers, enabling seamless communication and management of the custom sender address.

3. The records will need to be verified once uploaded. This can take up to 48 hours. 

4. Click Add sender to add a custom sender address. If you don’t add a custom from address all newsletters will be sent from [e-mail] for US customers, or [e-mail] for EU customers.
