Hello, I work for a Real Estate Company and we have a task that we need help with. We offer certifications after our agents have taken a certain set of classes. Currently, we have a spreadsheet and we have the agents name in each row along with the email address and dates of when the classes were completed, if the cell is blank then it means they have not taken the class yet. We send out individual reminder emails every month manually copy/paste the row and send, but this is very tedious. We would like for this process to be automated where we can record the date when they have taken the class into the spreadsheet and at the end of the month it will automatically send each individual agent an update email. Please help any input would be greatly appreciated! I am attaching a screenshot of the spreadsheet we currently use.
