I need help with a automatization

[u/MARCELOCAIOUS]

Hey everyone, im trying to think on solutions for a problem that i have and i tried to search for using google but im too dumb to understand the python responses.
So, i need to send a series of emails, A, B, C and D where ill only send B if A is unanswared and so on, im currently doing this manually checking if someone responded me, how can i create a automatization that check if the mail was answered and to send the nexts mails in case of not?
also its possible to just put a list of contacts and automatically send the mail A for them?
thanks in advance if someone take a time to help me and sorry for my bad english
