Help Problem deleting email

[Android email question]

I have a Samsung Galaxy S7 running Marshmallow 6.0.1, new phone. When I delete mail from the server, it does not delete on my phone. I can delete email from the phone manually, but every other phone I've ever had deleted mail on the phone automatically once the mail was off the server. I know how to navigate to Server Settings and there's no such setting. Verizon has no idea how to accomplish this.

Are you syncing?

dunno what email program you are using, but Aqua Mail has a terrific following.

it has never, ever, failed to do what it should for me.
