I'm sorry if this sounds silly, as I'm not familiar with this area and looking for solution.
I'm currently using email from my shared host provider. You know like going to cpanel, email, create account and stuff. Then I add the email smtp info to flynax admincp and everything works OK.

However the host provide limit to 500 email send out per hours. Its OK, but I'm thinking of sending promotion email to my users, and I have more than 500 users. So I won't be able to do so with my current setup.

My question is, can I use a third party email service? Would it be as simple as create the account from third email provider service and input smtp info to Flynax admincp and I'm good to go?
Can someone recommend me a decent email service provider?

Thank you
