I believe this emails from scammers was prompted by the information of users that was compromised on the 17th of this month which is the hack of Trazor third party.
@Learn bitcoin was right on what he said below.
Even though they have regained access to their support center, the hacker still has a chance to use email spoofing and send emails to those Trezor users and try various hacking attempts like sending malware and asking them to download, or asking them to use new web portal which could be phishing and numerous more methods they may try. There are still a few percentage of people who might believe those emails and try those things.
Well it's good to let people know about this current situation, I'm not a trazor user but I'm always concern in knowing all this kind of event because in less than no time I will purchasing a hardware wallet and will not want to face this kind of risk using them.
