Adding Custom Fields to Post Notification Emails

I’m working with someone who would like to use MailPoet to notify users about upcoming events. (In this particular case, Modern Tribe’s Events Calendar is being used for the event management.)

Building the template and populating it with content has been extremely simple and straight-forward — thank you! — however, there was a request to include date & time information along with the excerpt, so I’m curious to know if modifying a post notification newsletter to include custom content is possible/will be in the near-future, or if there’s another way around this. (Perhaps an excerpt filter that would allow for the relevant date fields to be prepended/appended?)

While the manual excerpt field could be utilized here, this person is hoping not to have to resort to that because:

1. They don’t want to have to retype information they’ve already entered.
2. It would require modifying both their RSS feed and calendar template to prevent the dates & times from showing up in multiple places.

If the manual excerpt is the only way (at least for the foreseeable future) to implement this, that’s fine, I just want to confirm.

Thanks again, sure hope this message finds you well.
