You can schedule when you send emails in Gmail, though iOS 16 adds that feature to the built-in Mail app.

The app includes Google's video chat features as well. Like Microsoft with Outlook, Google constantly updates Gmail, adding such features as an Undo Send feature, customizable priority notifications, and the option to turn off the conversation view mode. In addition to Gmail, the app also supports a variety of IMAP and POP email accounts and Exchange. Automatic filters can sort out social notifications and spam mail, and users can get really get down to the nitty-gritty, setting rules for tagging incoming mail by sender and automatically shunting them into folders. The Gmail app supports multiple accounts and notifications, while also offering particularly handy tools for organizing your emails. And given all the features at your disposal, you may just want to do precisely that.

These days, you can even make Gmail your default email app on an iPhone. Google's Gmail is available by default on most Android devices, but you can also download it for iOS.
