@vietnam123 is your email address a hotmail account? Are you using shared web hosting?
@vietnam123 that's odd. Not even in your spam folder?
There's a wordpress plugin which enables you to configure smtp for wordpress use. Maybe you could try with that
Installed a fresh new WordPress last night and GoDaddy automatically installs Ninja Forms. Presumably that is because it's known to work well on their Managed WordPress hosting platform. You could test and see if email gets through to you setting up Ninja Forms as your control.
