The Mail app for iOS sends and receives emails from one or more accounts. After you configure a second (or subsequent) email account, you'll unlock the functionality to specify the outgoing account for a given message.

Instructions in this article apply to iOS 12 but work on all currently supported prior versions of iOS.

How to Use Several Accounts in iOS Mail

When you change the From line of an outgoing message, you also change the account from which the message is sent. For example, if you enrolled an iCloud and a Gmail account on your iPhone, and you switch from one account to the other when you send a message, then the outgoing message appears in that account's Sent Mail folder, and replies are delivered to the inbox of the account that sent it.

In other words: You're changing the account, not merely the address, that governs that particular message.
