Sorry to hear you haven't received your email.
Occasionally emails can get lost online, what's most common these days is that they are incorrectly filtered into your SPAM folder.
Here's what to do next:
1. Please go and check your SPAM or junk folder to ensure that our email@example.com was not incorrectly redirected to your spam folder. If it has been, please restore firstname.lastname@example.org to your inbox, and make sure to whitelist us. You can know how to whitelist us here so future emails go directly to your inbox.
2. If you have not received your email and it has been more than 1 hour, and it's not in your spam folder, then please feel free to contact our support team here who'd be happy to investigate it for you.
3. If you need to get your login details resent to you, you can do so by following this process here
Hope this helps. Wish you all the best.
