Before sending emails with SelfMailKit, you need to create a domain and add the DNS records to your registrar. This ensures good deliverability and authentication.

This is what it looks like when you create a domain:

Let’s break down the records and learn how to add them to your registrar.

​
DKIM and SPF Records

These records are required for email authentication and deliverability.

​
DMARC Record

Highly recommended for enhanced security and deliverability monitoring.

​
Email Receiving

Required if you want to receive emails in the native built-in SelfMailKit Inbox. If you don’t need to receive emails, you can skip this record.

TypeHost / NameValuePriorityTTL
MXyour-domain.cominbound-smtp.ses-region.amazonaws.com10Auto

After adding these records, you need to wait for DNS propagation. Generally, it takes a few minutes, but sometimes it can take up to 48 hours. Click the Check Verification button in the SelfMailKit dashboard to see the status.

​
Common Issues and Solutions

​
If records aren’t verifying:

  1. Check for typos in the Host/Name fields
  2. Ensure you’ve replaced with your actual domain
  3. Verify the record types (TXT vs MX)
  4. Wait for DNS propagation (up to 48 hours)
  5. Use DNS lookup tools to verify record publication

If you need help:

  • Use the dashboard’s copy buttons to avoid typos
  • Contact support if records aren’t verified after 48 hours or you need help with anything else
  • Check your DNS provider’s specific documentation for custom requirements
