Overview

Custom email domains let your organization send email from your own domain so outgoing messages display your company in sender information. Configuration uses DNS records and DKIM authentication managed from Organization Settings.

​
Prerequisites

  • Elementum permissions: Organization Admin access
  • DNS: Ability to create records at your DNS provider
  • Domain: You must own or control the domain you add

​
Add and verify a domain

​
Add the domain

  1. Open Organization Settings
  2. Select the Email Domains tab
  3. Click Add Domain
  4. Enter your domain (for example, elementum.ai or app.elementum.ai)

​
Configure DNS

Add the DNS records shown in the Elementum UI at your DNS provider. The UI lists the exact record types and values, including DKIM records used for authentication.

​
Verification

  1. After adding DNS records, click Verify Configuration
  2. Verification can take up to 24 hours
  3. Status indicators show configuration state:
    • ✅ Green: Properly configured
    • ⚠️ Yellow: Pending verification
    • ❌ Red: Configuration error

​
Test sending

Once the domain is verified:
  1. Open an app that has an automation configured to send email (for example, surveys or file attachments)
  2. Trigger the automation so it sends an email to a test address
  3. Confirm the received message shows your domain in the From field

​
Default domain

  1. Select a verified domain
  2. Click Set as Default
  3. Confirm the selection

​
Monitoring and notifications

Elementum checks domain validity every six hours. If a configuration becomes invalid, the platform notifies configured recipients and falls back to sending from elementum.io until the domain is valid again. Notification topics include invalid domain configuration, failed email validation, and domain verification issues. To configure who receives system and error notifications:
  1. Open Organization Settings
  2. Open System Notifications
  3. Add users or groups

​
Best practices

  • Monitor domain status regularly, especially after DNS changes
  • Keep DNS records aligned with the values shown in Elementum
  • Maintain backup admin contacts for notifications
  • Review email sending logs periodically

​
Troubleshooting

If the domain shows errors:
  1. Confirm DNS records match the UI exactly
  2. Check for conflicting records at your DNS provider
  3. Confirm you control the domain
  4. Contact support if problems continue

​
Technical reference

  • Outgoing mail uses DKIM for authentication (records are provided in the UI)
  • Reply-To continues to use an elementum.io address where applicable
  • Email sent using custom domains is logged for auditing
