sender

That Snapchat deceptively told its users that the sender would be notified if a recipient took a screenshot of a snap.

The sender and receiver pay the driver a few hryvnia—the Ukrainian currency—on either end.

But police had never heard of  "Kassim, A." — the name written as the sender.

I would just return everything to sender, and closed out the P.O. box.

Gifts from others are allegedly returned to the sender with a polite note from the royal family.

A letter-form which enables the sender to address his Seniors more abruptly than he would dare to do without its assistance.

There is always, of course, the broad spirit of a cable which depends on the temperament of the sender.

To find out that the sender of the League letters had fair hair narrowed the search down a little.

There was an opinion among some of the people that the letter should not be stamped by the sender.

So you see these actions are likely to revert to the sender, even if they are successful.
