Diligently, using your webmail service or mail application of choice on a computing device, with a bit of copying and pasting (or just good ol' typing)?
For clarity, are you talking about pushing the timed activity's summary statistics by way of the human-readable content of a mail message to the recipient, or just giving him/her a way to retrieve or pull the information online from Garmin Connect when he/she is ready to do so by way of a link to a page?
Either way, one would expect you initiate the sending in each instance manually, instead of having Garmin Connect take a standing instruction from you in a set-and-forget manner and provide the service automatically.
