It looks like you guys have some sort of intermittent failure sending emails through Amazon SES.
For anyone else who has this issue, log into the account you need to activate and browse to

The email address should already be populated, click the button to send the email. Check your email. If you don't get something almost immediately, perform the step again. Rinse repeat until you get an email.
If you get an email but it says it's an invalid link, that means the email was not for the latest activation request button click, so you might need to give it more time before re-requesting the email to be sent to you.
