Can I bypass the webhost when sending emails

Can I bypass the webhost when sending emails

Hi, I'm able to send emails perfectly fine from the zoho website to my normal email. However, I'm signed up with 000webhost and their email system doesn't really work at all.

The php mail function is one of the things which doesn't do anything, so is there any way I can get around this by directly connecting to the zoho mail and sending stuff?
