Our hosting provider only supports using FTP, not sFTP. Is this safe enough?

My limited skills/knowledge tell me that standard FTP is completely unencrypted and that it only takes minutes (or even seconds) for your system to be compromised if you send admin credentials unencrypted over the internet. In addition, they just sent me the admin credentials in a standard email, which is also a security violation in my world. What should I do? Go ahead with FTP as I am told, or choose a different approach? -------- Thanks all for your advice and insights! I had the gut feeling that these people have no security awareness at all and that the only sensible thing to do is to move, just as you suggest. Thank you for confirming that!
