I need some insight and data on the appropriate frequency of email reminders to a user to complete a specific task they have not submitted. The system will delete their information automatically after 30 days of inactivity, but we need to send them reminders to complete and submit their information and inform them that it will be deleted if they do not act.
As far as I am aware, the user cannot unsubscribe from this list because it's a business requirement to remind them to complete their information or it will be deleted, nor will they have the option to choose to receive less email. The only times we email them are confirmation emails and reminder emails.
Here are my questions related to this -
- How many emails would be appropriate in this situation and why?
- Is it necessary to inform them we when have deleted their information, though previous email(s) would notify them of impending deletion, and prompt them to start again with a link to our site in that email?
