Does think that a Gmail business account will be good for your campaign. Or a regular email is fine.
Let Me Know Thanks

You will need your own website, which will come with an email account(most do) so use that one - you can redirect your business account emails to your gmail you wont have to check multiple accounts.

I have noticed that people respond quicker when you have your own domain email, it also looks more professional.
Thanks
