In practice

It lets you send from one address and receive answers at another, such as a platform’s sending address and your own inbox. A Reply-To that differs strongly from the From address can look odd to filters, so keep them related.

Verification and sending

Not related to verification; make sure the Reply-To address is monitored, or replies are lost.
