In the future, sending a TON of requests to the same email will not change anything. Maybe one will slip through, but the chances of that are EXTREMELY thin and I have not seen it actually happen despite people saying they have. When it goes down, it's a widespread issue that is impacting anybody. Every email added to the queue likely just adds to the number of backlogged emails that need to be sent.

If you notice emails not sending within a few hours max, it's likely messed up again and the best course of action is likely just to wait for TNT to fix their shit. Fingers crossed it's up for good this time, but I'm not holding my breath. On discord people are pushing "put in a ticket!1!1" but really that's just as slow as just waiting for the issue to clear up. Just a word to the wise in case this happens to be an ongoing issue.
