Question About eMail Setup on iPhone

Hello all. Subject is pretty accurate. I set up my gmail account on my iPhone 7 last week, and everything's working as it should thus far. However, I cannot find a way to set up additional email accounts on there. We've been experiencing wi-fi issues here in my apartment complex, and I haven't had reliable access to my other email account on the Mac. I'm wondering if accessing it from my iPhone will perhaps help the situation a bit. Reception on there has been relatively good, especially when my Mac is shut down and I'm not doing something with the A-Lady. Tia for anybody's help.
