Hola Mailjet team,

We currently use Mailjet to manage and send our email campaigns. Our subscribers can join our contact list through two main sources:

A) API -› When making a reservation on our website (Covermanager), by checking the commercial communications consent box.

B) By filling out a direct subscription form (popup) on our website.

At the moment, Mailjet does not provide a way to distinguish the origin of a subscriber. Having an origin breakdown would be extremely valuable to us, as it would allow us to better understand which channels are most effective for acquiring subscribers.

We would love to see a feature that tracks and reports the subscription source/origin (e.g., “Reservation opt-in” vs. “Direct form signup”) within Mailjet’s contact list management.

Thank you for considering this improvement!

We believe it would bring great value not only to us but also to many other Mailjet users.
