I'm wondering: when you've send out an email, how long will Adobe Campaign register opens on this delivery?
Is this based on the delivery limit? Of is it a default time?
Opens will continue to record forever, afaik. Raw logs are retained as per davidk23955130's comment.
There's also resources validity period, which governs how long images and mirror pages are available (default 60 days).
Set that in the template to use across all new deliveries. You can also extend extant deliveries, though this requires altering xml files on the tracking servers.
Yes you can modify it at delivery level in the properties or at instance level under deployment wizard>Email channel
Can we modify this resource validity period?If so How?
You can find the information under deployment wizard and the last tab (purge of data). Per default, the retention period is 180 days
