eVars in email opens

We currently have email opens working pretty well, we have an image in place that calls our adobe endpoint and passes variables, both props and evars.  I was thinking though, what's the purpose of using an evar in an email open, especially when not all email clients don't support cookies (I'm guessing browser based clients may support cookies).  If a true session was being set with a visitorID and all, I could see the point of having a session variable like an evar.  Is there something I'm missing?

Hi Philip,

By setting email open in an eVar you can set allocation and expiration based on your need to analyze user behaviour. i.e. what percentage of users those open email also makes a purchase.

while prop is always allocation last touch and expired on hit so can't help you answer user actions not performed in a same hit.

Note: eVar does not necessarily use cookie to set expiration, all calculations happens in backend reporting platform. explained here Visitor engagement expiration set to 1 day: When does it expire?

Thanks,

Asheesh

Interesting, but this would mean we'd need to pass the vid on each request, correct?  We have something that we could use, but we're not using it yet (I inherited this application and I'm busy trying to undo several knots).

Nope! Adobe does it for you, however you can replace adobe vid with custom vid, in that case you will need to pass your custom vid in each request.

Looking through my clickstream data it seems that some email packages do support cookies, but not all do.  I've run a test by setting the vid to a unique id and that seemed to track nicely in the clickstream and it keeps my visits (20 minute increments) together and it keeps my unique visitor proper.  Plus I'd be able to easily track usage across devices, which would help answer the question of how many times to people use both phone and desktop for email (or at least multiple devices).
