(Read Receipts?) The organization I work with uses MyEmma to e-mail its employees. We have recently started sending out campaigns as a part of a new training program and have been tracking who has opened and not opened the mailings (via an ad hoc spreadsheet as MyEmma cannot yet do this...). Several employees have complained they are opening their emails but still show up on our list of “did not opens”. Is there a way for them to prompt them with read receipts requests?
