We had an issue with our email provider which started last night around 11.40 pm PST as a result of which some new users were unable to verify their email after signing up. The issue has been fixed today as of 2 pm PST.
I apologize about any email verification issues you might have faced. These issues have been resolved now.
We are putting measures in place to prevent this from happening again.
Again, apologies for the inconvenience.
