I need help setting up my email on my iPad and iphone

I feel like an idiot. I used to be able to do this stuff. I have a Mac and email is working. My email was working on my iPhone but I deleted it. I have a new iPad and I need it there. I used to have imap but I can’t find it. It just seems to be pop just comes up. It is set up in imap on my MacBook Pro and on my old iPad that will be reset. But I need the email set up in imap on my iPhone and iPad Air. Any help would be appreciated.
