What Is Postmark and How to Add Postmark Records

Postmark is a transactional email delivery service that ensures your WordPress site’s emails—such as contact form submissions, password resets, and order confirmations—are delivered quickly and reliably to recipients' inboxes. At BionicWP, we integrate Postmark SMTP into every hosted site to maximize email deliverability and prevent messages from being marked as spam.​

To authenticate your domain and enhance email deliverability, you need to add specific DNS records provided by Postmark.​

Postmark uses domain authentication methods like DKIM (DomainKeys Identified Mail) and a custom Return-Path to verify that emails sent from your domain are legitimate. By adding these DNS records, you establish trust with email providers, reducing the likelihood of your emails being filtered as spam.​

1 Log into https://my.bionicwp.com/

2 Go to “Sites” from the left navigation.

3 Find the site you want to add records for and then click on the screenshot or URL of that to go to the site dashboard.

4 In the site dashboard, switch to the  “Miscellaneous” tab.

5 scroll down to the “Postmark” section.

6 There are two types of records to add, a DKIM (which is a TXT record) and a Return path (which is a CNAME record) in order for Postmark to work.

7 Add the DKIM record as type TXT to your DNS, with the Host and Value that was generated.

8 Add the Return Path record as type CNAME to your DNS, with the Host and Value that was generated.

9 Once the DKIM and the CNAME record are added, it can take up to fortyeight hours for the DNS changes to propagate.

10 Make sure all your “From Email” in your forms are set to send from the domain of the site, for example, “website@domain.com“. If the “From email” is not set to send from the domain in question your emails won’t send.
