Remind participants of their next steps

You will have notified your participants of their matches, and prompted them to undertake speed mentoring and select a long-term mentor.

You could, additionally, send a reminder email a few days or weeks later, to prompt mentees to select a long-term mentor. This might be helpful because participants might not have seen the original email, they might have misplaced it, or might have simply forgotten to do so.

You could use a slightly adapted version of your earlier emails as a prompt.
