Sign Up Confirmation email isn't received

Hi

I have installed the Mail Poet newsletter on my site. I was able to get the mailing list made, and put the signup form widget on my side bar. When I go to test it with my own email it says “check for email to confirm…” the email never comes. I tried with different email addresses and no luck.

Therefore no one can sign up for the email 🙁

Please advise.
