Email with Link for Check in

Is there a way with the free version to set when the email to the client goes out with the link for them to check in? Or, when do you usually send the client the link? Right when they schedule with you, 24 hours beforehand? I work out of a University Health and Counseling Clinic, where most students are not the best at keeping track of their emails. Thanks for any feedback!

I send the invite the day before so it’s are,I dre and include the time and date
