Conversion Tracking

Conversions are recorded with a pixel: a 1×1 image request (or a server-to-server GET) that carries the subscriber's hashed email.

Ad Journey conversion pixel

Every Ad Journey with a conversion goal gets its own pixel token, shown in the journey's detail panel. Fire it on your confirmation page or from your server:

<img src="https://mailadx.com/api/v1/cv/{pixelToken}?eh={sha256EmailHash}&v={valueUsdCents}"
     width="1" height="1" alt="" />
  • eh — SHA-256 of the subscriber's lower-cased email address (64 hex characters).
  • v — optional conversion value in US cents (e.g. 4999 for $49.99).
  • The endpoint is public, returns a transparent GIF with Cache-Control: no-store, and answers the same way for an unknown token, so it reveals nothing to someone probing it.
  • A subscriber waiting at a journey's conversion goal moves to goal met once the pixel fires. Conversions appear in Journey Reports → Conversions.
  • The token can be rotated from the journey (old pixels stop counting).

Line-item conversions (leads campaigns)

When a reader clicks an ad from a line item with a leads objective (or CPL bid type), MailAdx adds a signed, 30-day token to your landing URL as mxcv=…. Add our tag to your site to report the conversion:

<!-- every page (at least the landing page) -->
<script src="https://www.mailadx.com/api/v1/track/cv.js" async></script>

<!-- confirmation / thank-you page, instead of the tag above -->
<script src="https://www.mailadx.com/api/v1/track/cv.js?convert=1" async></script>
  • The tag keeps the token on the visitor's browser for 30 days (first-party storage only) and reports one conversion when the confirmation tag loads. Single-page apps can call window.mailadx.convert() after a successful sign-up instead.
  • Each click counts at most one conversion — reloading the thank-you page does not add more.
  • Visitors who did not arrive from a MailAdx ad have no token, and the tag does nothing for them.
  • Landing URLs of branding and click campaigns are left exactly as you entered them.

Clicks

Every click goes through MailAdx's click URL, which records the click and redirects to your destination. Add UTM parameters to the destination URL in the creative to see MailAdx traffic in your own analytics.
