I have n employee who constantly insists he's not receiving my
messages. Is
there a way to set up return receipt for one particular person?
If you think the employee is lying, call them after every e-mail that
you send to them to tell them to come to your office. Then, when they
show up, tell them that you sent them an e-mail and that's all you
wanted to tell them. If they don't show up when you tell them to then
you have something to add to their file regarding their behavior which
will affect their review(s). After you nuisance them enough, they'll
stop pretending that they aren't receiving your e-mails.
You could use MsgTag or other spammer-knockoff services that try to
track when someone opens your e-mail, but they are very easily
defeated. In fact, the user may simply be deleting your mails without
ever opening them perhaps even by using a rule.
If this employee is on-site then tell them to uninstall all the
anti-spam software that they are using since the company should be
handling that upstream and the employee should be reporting any spam
leakage to the mail admin rather than adding another and probably
flaky layer of spam filtering at their endpoint.
If you believe the employee is truly not receiving your mails then go
talk to your mail admin about the problem. For example, you could ask
if your mails are getting into that employee's mailbox.
