How do I code auto email alerts when a certificate expires?
 

I've built an Excel database to keep track of training certificates for a
group of volunteers. Some of these expire every 1-3 years, the certificates
are earned at different times throughout a calendar year and there's 85
volunteers, so too many files to hand-search on a regular basis. If I enter
the date a particular certificate was earned, and then code it with a date,
say, 90 days before it's due to expire, is there a way to get that alert sent
to the particular volunteer and myself via email as a reminder that they are
due for recertification? Is this even doable in Excel, or is this better
addressed in Access? Thanks in advance!
