haveibeenpwned doesn't mention either Trezor or Mailchimp to their "Recently added breaches" list, so i don't think there's way to know unless you got scam email about trezor wallet/app.
It's still too early for that, and we haven't heard anything about the leaked data being sold online or being posted somewhere publicly. I just took a quick look at their reddit page. Considering the situation, it's positive that they aren't being flooded with new threads from customers complaining about having lost funds due to the emails they received. There are only sporadic mentions of such in some of the older threads. 
Topic: Trezor mailing list breached - page 2. (Read 418 times)
- Trezor users who have never signed up to any newsletter claim to have received the phishing emails as well.
They could have a big problems if GDPR office will audit them. In EU penalty fees sometimes could be insane.

Trezor customer order data is purged after 90 days. The data contained in this leak originates from a separate database secured by a third party.
In general, why is there no password (special character) assigned to each account that is added at the end of each message?
I think that such an update will make it more difficult for the scammers, although I don't think they will delete their database within the 90 days or give proof of that.
Trezor's first explanation of the hack has been posed on their blog:
Ongoing phishing attacks on Trezor users
We are already familiar with most of the content in the post, so there is no need to comment on anything in particular.
However, there is one interesting part.

Hopefully that third-party (MailChimp) only has data on Ledger newsletter recipients and this isn't their way of saying that the 3rd party has access to more than that and stores it for longer periods of time. 
If you think that only Trezor emails were breached from Mailchimp hack then you are up for a big surprise soon 
Anything crypto related that you ever signed up could be exposed, so you can expect to receive similar scam emails from exchanges and other wallets.
I received this fake email on my temp email address (that was only used for Trezor newsletter), and I knew it from start that this is a scam, even more when I saw puny code domain address...
Looks like trezor is trying hard to compete with ledger in making bad decisions

After running full node, using Tor, the best way to privacy is by not given out your personal data to another party, once it is given out, it is no more private. It is just like once a word left your month, like telling a friend about something, even if it is said to be kept secret, do not be surprised if you hear the secret from a place far from your home or if known to the public. If the word remains to yourself, then it remains perfectly secret. The only way to this type of privacy is by using paper wallet or wallet on airgapped device.
That's not good [SMH]! Why did they give those emails to MailChimp [those emails have nothing to do with their newsletter]?
Any company can do that, any company can sell data, the best is to just know how to go about it, using everything not link to you to purchase hardware wallet (not only Trezor, but all others, they are all the same). Only when you personal data are protected and private is when you have never given it to any company, once you provide a company with your personal data, then it is no more private but public because the company it is given to can be hacked and the data stolen, or the company can give it out or sell it to other companies.

Who knows mate. Who knows if the post I read is even true. I am sure some will be happy to get to throw some dirt around and participate in the attack and destruction. Some claims might even be fake.IIRC, there was a way to either disable or hide that feature on each subreddit [they should temporarily do it].
I am not that familiar with reddit to be honest. I do expect that channel moderators have some sort of tag next to their names, right? What I have noticed in all these posts is that I can't see Trezor moderators post anything or reply to user concerns. 
- Trezor users who have never signed up to any newsletter claim to have received the phishing emails as well.
- I'm glad I bought my HW from one of their official resellers.
- Reddit posts warning users about the attack are being downvoted.
This user claims he lost £55.000 after he received a phishing email.
Another "victim".List of other domains:
I got an update notification from the Trezor Suite and I installed the last version yesterday, I hope it's not the case as the Electrum fake update from a few years ago.
I'll check it as soon as I get back home.
Unless you downloaded the software from a link you received in your email, you should be fine. The official Trezor Suite software has not been compromised and hopefully won't be. A malware-infected app that also requires you to enter your seed is what is causing all the problems. I'll check it as soon as I get back home.
You can verify the binaries of your Trezor Suite following this guide. It should be noted that you are downloading everything from Trezor's official download page. Similarly to the way you verify the signatures for Ledger software, you have to trust that what is hosted on the site is genuine and hasn't been compromised.
How do I check if my email address has been compromised or not, especially considering the fact that the haveibeenpwned platform says I am good? Is the list of compromised emails even available to the public?
It's probably to early to tell at this stage. I am sure they are still investigating how many people have been affected. 
Trezor users who have never signed up to any newsletter claim to have received the phishing emails as well.
Interestingly, I have been subscribed to their email list for a while but haven't received any phishing trezor emails; my spam folder is also empty. How do I check if my email address has been compromised or not, especially considering the fact that the haveibeenpwned platform says I am good? Is the list of compromised emails even available to the public?Would not that imply that Trezor lied to us when when said they make anonymous client's data after a centain period of time after a purchase?
Implying those e-mails were used to buy a Trezor but were not signed up to the newsletter, of course.
The more logical explanation would be that random scammers took advantage of the given situation and started to massively attack each email address known as associated with cryptocurrency activities or hardware wallets purchases. For example, those users whose emails were compromised in the Ledger data breach could also become victims of Trezor phishing attacks.Implying those e-mails were used to buy a Trezor but were not signed up to the newsletter, of course.
It could also be that Trezor lied to us and never deleted customers' data.
Oh not Trezor too. All these hardware wallets had their user data compromised. I got an update notification from the Trezor Suite and I installed the last version yesterday, I hope it's not the case as the Electrum fake update from a few years ago.
I'll check it as soon as I get back home.

It's unclear how much time has passed after that user allegedly purchased his hardware wallet and received that phishing email. All companies will put their interest in front of their client's. What they say and what they actually do can be two different things. Storing data longer than needed or not deleting it in time is what they will do rather than having Mr. government/tax officer come knocking and requesting data or handing out fines. Implying those e-mails were used to buy a Trezor but were not signed up to the newsletter, of course.
This user claims he lost £55.000 after he received a phishing email. He though it was legit, so he downloaded the fake Trezor software, and INSERTED HIS SEED when requested. No matter how often you hear warnings never to do that, it's obviously not enough.
Shame on Trezor, they should have known better before handing over such information of their clients to a third party.

A new day brings about a new breach that has affected users of hardware wallets.
Trezor has today confirmed that the MailChimp platform for marketing services has been compromised by an insider. Crypto companies were the target of the breach.
Trezor has confirmed that the emails of their users have been obtained. Phishing sites have been created and there are reports of fake emails being sent to Trezor users instructing them to download a new version of the Trezor Suite. The email that is circulating is professionally written and explains how a security incident is the cause of an urgent upgrade. Here is how the phishing emails look.

Trezor doesn't know the full scope of the attack just yet. Let's hope it's only email addresses and nothing more. The fake emails are being sent from [email protected]! This is a phishing site, don't download or open anything you get from this domain!
Trezor has confirmed they won't be sending out their newsletters until further notice.
No information about the leak on MailChimp's Twitter feed yet.
