Domains and e-mails

Hello,
this is probably a stupid question but please bear with me.

I am very unhappy with my host (who also handles my domain) and I'm planning on moving my domain and hosting elsewhere. But what I wanted to know is; if I transfer the domain, will everything be alright e-mail wise, or do is there something I have to do or purchase to keep my e-mail addresses? Or is it just quick and painless?

I am very new to this; I've never transferred a domain before.

just transfer the domain to a good host and buy some space for ur domain and email. yes u can use the same email box here.hope this clarifies ur doubt..
thanks
