Update: I've received another email from SH (1 day later).
We just wanted to let you know that your name, XXXXXX.com has been transferred to the customer who recently purchased it.
As a result, we have deposited $300 into your Squadhelp account. Congratulations!

Super efficient! I doubt that all domains will transfer that quickly, I suppose it depends on where the purchaser wants the domain transferred to, some registrars take up to 7 days to confirm. Thrilled that this one was quick and easy and I didn't have to do a thing! Thank you SH.
