Setting the timing of triggered mailing

The Run Frequency and Time from trigger event settings work together to determine the timing of triggered mailings. In general, the Time from trigger event setting is constrained by the Run Frequency setting. If you set both to the same time, the results can be unexpected.

For example: If set Run Frequency and Time from Trigger Event both to one hour. Your trigger is When a recipient opens their email.  

At 11:59am, someone opens their email. The Run Frequency setting is Check every hour, so at 12pm, Aurea List Manager checks and sees that someone opened their email. Since the Time from trigger event setting is Send after one hour, and one hour has not passed, the triggered mailing is not sent. ListManager checks again at 1:00 pm.; since more than an hour has passed since it found a qualifying event (the opened email), the mailing is sent.

However, if the email was opened only two minutes later, at 12:01pm. The next time Aurea List Manager checks to see who has opened their mail is 1:00pm. When it does, it sees that mail was opened at 12:01pm., but since an hour has not quite passed, the Time from trigger event setting's criteria has not been met, so the triggered mailing is not sent. Aurea List Managerchecks again at 2:00pm.; by this time, more than an hour has passed, so the triggered mailing is sent.

Therefore, setting Time from trigger event to a particular interval does not mean a mailing will be triggered at precisely that interval. Results will generally be more predictable if Run Frequencyhas a lower setting than Time from Trigger Event.
