Judge.me sends emails on your behalf via a third-party service provider for emails: Postmark. Here are some recommendations that we collected from Postmark that might be helpful if you want to improve your emails’ reliability:

1. Add DKIM

DKIM, short for Domain Key Identified Mail, is a digital signature that’s added to every email sent from your domain. The DKIM can be added to your domain’s DNS records. This signature is a set of characters that are not visible under a normal view from recipients’ normal view but often hidden in the source code of the emails. The recipient’s server will send a public key to your domain’s DNS to verify the records. Once it’s successful, the message is then considered to be reliable. 

Adding DKIM, while not required, DKIM records increase the legitimacy of your emails and help them to be less likely in spam folders as it makes it harder to spoof emails from your domain.

DKIMs can also be used to build up your emails’ reputation with internet service providers such as Yahoo and Google so that your emails are more likely to be delivered.

The DKIM records at the moment are not published to all Judge.me’s users but you can easily obtain one if you write an email to support@judge.me, we’re available 24/7!

2. Add return-path

Return-path is the address where email feedbacks are sent, especially bounces. The return-path is visible in a recipient’s normal view (header) and is helpful if you want to increase your domain’s reputation.

The default return-path for emails sending through Postmark is pm_bounces@pm.mtasv.net.

To set up the return-path, you need to do the following steps:

  1. Add a CNAME record to your DNS that points to pm.mtasv.net
  2. Enter Hostname as pm-bounces
  3. Wait for 24-48 hours to receive an email from Postmark to verify the changes

3. Add SPF

SPF records are automatically handled by Postmark so you don’t have to add this information anymore.
