tl;dr;
We use SendGrid to send our emails out. By default, SendGrid enables link tracking. Link tracking was causing issues with allowing users to verify their accounts. In short, I disabled link tracking, and links should work for all new emails in the future.
Contact support if you need your account activated. [email protected] from the email you used to sign up.
Issue
When new users sign up or when existing users reset their password, an email is sent to verify ownership of the account. These emails are sent from us through a service called SendGrid.
SendGrid, by default, will mask all the URLs to enable what they call link tracking. It's a marketing thing to track engagement with email. I have no use for it, but I didn't disable it before.
The issue is that sometimes this link doesn't resolve. An HTTPS error is shown to the user.
Resolution
The quickest and most logical resolution was to disable link tracking. I never use it. I did just that; however, any previous emails sent will still be broken.
I will continue to investigate the issue in hopes of resolving previous links.
If you are unable to verify your account, please email [email protected] from the email you used to sign up. We'll manually verify each account that hasn't been able to be activated.
