Open & click tracking changelog

Changes to Open & click tracking: new features, improvements and fixes.

September 2026

  1. Fixed

    Sending domain matching and subdomain settings

    Sending domainsEmail APISMTP relayOpen & click trackingInbound email

    • The API and SMTP match the From domain without regard to letter case, so ada@Acme.com sends from the verified domain acme.com.
    • Changing a domain’s tracking or inbound subdomain in the dashboard, or with tracking_key and inbound_key in Update a domain, now saves the new value. Publish the DNS record for the new name and verify it.
  2. Changed

    Emails send untracked until the tracking domain is verified

    Open & click trackingEmail API

    A send request with tracking turned on used to fail with 422 when the sending domain had no verified tracking CNAME. Emailit now accepts the email and sends it without rewriting links or adding the open pixel.

    To track opens and clicks, publish the tracking CNAME record for your domain and verify it. See Custom tracking domain.

  3. Improved

    IP addresses for clicks, loads and unsubscribes

    Email logsCampaignsOpen & click tracking

    The Loads and Clicks tabs on an email show the IP address of each event, and campaign reports show the latest IP address for each contact who loaded or clicked. Unsubscribes now record and display the IP address too.

    See Email details.

  4. Changed

    Tracking requires a custom tracking domain

    Open & click trackingSending domains

    To track opens and clicks, publish a CNAME record from go.yourdomain.com (or your custom tracking subdomain) to go.emailitmail.com and verify it. The Track loads and Track clicks switches on a domain turn on only after the record is verified.

    Links and open pixels in emails you sent earlier with shared tracking links keep working. See Custom tracking domain.

December 2025

  1. New

    Custom tracking URLs and the Domains rename

    Open & click trackingSending domains

    Add a CNAME record from go.yourdomain.com to go.emailitmail.com to serve tracking links from your own domain, or choose another subdomain with the domain’s tracking key.

    Sending Domains are now called Domains in the dashboard, and the API endpoint /v2/sending-domains moved to /v2/domains. See Custom tracking domain.
