Why can't I send mail to Netlify?

Today I created a Netlify account and tried to contact them via the contact form but it showed me the following error.
I already have a Netlify account.
So I sent an e-mail to support@netlify.com and it showed the same error again.

Hiya @cnktmp :wave:t6: welcome to the Netlify support forums! :netliconfetti:

I’m not sure why you are receiving that request did you verify your email after signing up?

Additionally, you are free to post your questions here in the forums! I see you are on the starter plan and we do not offer help desk support for customers on our starter plan.
