Applies to: WebinarJam and EverWebinar

Learn how to authenticate your email domain so your webinar emails reach your attendees’ inboxes.

WebinarJam and EverWebinar send important messages like confirmations, reminders, and replay links. Email authentication helps verify that your messages are legitimate and improves deliverability.

Without it, your emails are more likely to:

  • Land in spam folders
  • Be blocked by email providers
  • Miss your attendees entirely

Setting up authentication helps ensure your registrants receive:

  • Confirmation emails
  • Reminder notifications
  • Replay links

How email authentication works

To authenticate your domain, you’ll add three types of DNS records:

  • DKIM: verifies that emails are sent from your domain
  • SPF: allows WebinarJam (or your SMTP provider) to send emails on your behalf
  • DMARC: adds rules and reporting for email authentication

Don’t worry if these terms are new. The steps below will guide you through the process.

Before you begin

  • You’ll need access to your domain’s DNS settings (through your domain provider)
  • Authentication must be completed for each domain you use to send emails
  • If you use a third-party CRM or autoresponder, follow their authentication process instead

Email authentication checklist

Follow the steps below to authenticate your sender domain.

Step 1: Add a custom sender email

A custom domain email address adds legitimacy to your business communications and can improve your deliverability. 

Learn where to customize your sender email address.

Step 2: Add your domain to WebinarJam

Connect your domain to your account to generate DKIM records.

Learn about generating DKIM records for webinar notifications

Step 3: Add DKIM records to your DNS

Copy the DKIM records generated by your WebinarJam account and add them to your custom email DNS settings to complete the authentication loop between WebinarJam and your domain.

Learn how to publish DKIM records.

Step 4: Update your SPF record (if using SMTP)

If you use an external SMTP service, add or update your SPF record to authorize WebinarJam.

Learn more about creating or updating an SPF record if you use an integrated SMTP service.

Important:

If you use the default WebinarJam Mail service, skip this step. It is handled automatically as part of the DKIM records you set up in the previous step.

Step 5: Add a DMARC record

Create a DMARC policy in your DNS to:

  • Monitor authentication results
  • Improve email security
  • Receive reports about your domain

Learn how to define and publish a DMARC policy.

Step 6: Test your setup

Use available tools (from your provider or online) to:

  • Verify your DNS records
  • Confirm authentication is working correctly
Important:
  • Per-domain setup: Authentication must be completed for each sending domain
  • New domains: Repeat this process if you use a different sender email in the future
  • CRM users: If sending emails through an integrated CRM, follow their authentication steps instead
