Does an email address @att.net offer the capability to delete or move emails on various devices

I would like to have my att.net email address sync accross multiple devices (phone, desktop, laptop, tablet), like if I delete an email on one device, I would like it to be deleted on all devices.

I think it has to do with IMAP, but I don't know what that means or if emails @att.net are capable of having this done.

Thank you in advance for your help.
