I just re-subscribed at their web site. I was getting their email announcing their current deal every day up until about a week or so ago. Then they just stopped. I scrub my junk mail folders regularly and do not empty them until I give the contents a quick review.
Also, I was actually getting two such emails daily: at two separate email addresses! I guess that I had at some point subscribed using both emaill addresses. Plus my Fastmail account messages are auto-fetched by a Gmail account (for search purposes), so I actually saw three daily.
The daily emails to both addresses stopped at the same time, so if one got caught in a spam folder and I missed it, it is hard to believe that I missed it again for the other account. I have a feeling that they somehow purged their mailing list - either accidentally or intentionally.
Just seems like a weird occurrence that all emails from them have stopped being delivered to two separate email accounts at the exact same time! (Or maybe it was something I said?!?
