Head to the Invitations & Reminders tab on your Organization's Email page to set up Automated Reminders: Click ORGANIZATION in the main nav at the top of the screen, click the email icon in the left nav, choose the Invitations & Reminders tab, and look for the Automated Signature Reminders section:
Click that Add a Reminder button to add your first reminder. There are 3 steps:
Set your reminder timing
Customize the email template
Choose who to CC (if anyone)
You can create as many reminders as you'd like
Reminders can be based on (A) when you requested a signature from someone or (B) someone's signature due date... we suggest you do not mix these 2; use one or the other for all reminders
Reminders will play nicely if someone's signature due date is changed
Once you set some up, it'll look like this:
If you want to change the timing of a reminder, simply add a new one and then delete the old one. To delete a reminder, click Edit and then the red Delete link.
Once your reminders are going out, you may need to turn them off for a particular person. You can toggle whether or not a person gets reminders on your Org Members (or Org Friends) page. Click ORGANIZATION in the main nav, click the person's row to show their details, then toggle the auto-reminders setting to OFF.
