Hi everyone! Good news - you can already do this with Emma!
Using Emma’s document library, you can add calendar event files - called .ics files - to you library, and then link to them as you would any other file (like a PDF for example).
Since each calendar program is a little different, I can’t provide specific directions on how-to, but you can export events from iCal or Outlook as an .ics file. Then take the .ics file and load it into your document library, which is found here on the campaigns page:
Click on the “documents” button to open your library and upload the file.
Then while creating your mailing, you can turn any of your text into a link to this file. High-light the text of your choice and then look for the link button on the tool bar:
Then select the document as the link source:
When your recipients click on the link, they’ll be prompted to download the ics file - which will add the event to their calendar. I hope this helps!
