Carlos explains how to
use DKIM to improve
email deliverability with SES


How can I increase email deliverability for sending email with Amazon Simple Email Service (Amazon SES) by using Easy DKIM?

There are many variables that affect email deliverability because each Internet service provider (ISP) has its own internal rules and policies for accepting or rejecting email. Easy DKIM, or DomainKeys Identified Mail, is a feature of Amazon SES that signs every message that you send from a verified email address or domain with a DKIM signature that uses a 1024-bit DKIM key. DKIM can help you control and configure SES to increase deliverability. For more information, see Easy DKIM in Amazon SES.

Follow these instructions to enable DKIM for your domain and update the DNS settings:

  1. Open the Amazon SES console, and choose Domains from the navigation pane.
  2. From Domain Identities, choose your domain, expand the DKIM section, then choose Generate DKIM Settings.
  3. You will see a table with three CNAME records that you must configure with your DNS.
    Note: If you are not using Amazon Route 53, you must update your DNS settings with your DNS service provider.
  4. To configure DNS for Amazon Route 53, choose Use Route 53, and then choose Create Record Sets.
  5. Open the Amazon Route 53 console, and then choose Hosted zones.

After the verification process is complete, all of the SES email from your domain is DKIM signed.
