Though I haven't checked whether I've received mail or not, even if there is an email from Trezor, I don't bother to click on it. Because I don't have business with Trezor since it's not a web wallet. So why should I cooperate with Trezor? Sometimes I see the mail, and I just delete it without reading it. Because I consider them as promotional mail that I really don't need. I feel this is better practice to avoid such mail. From data breach scammers attacking Trezor users. Some might fall into the trap as well.
Even for firmware upgrades or software updates, I don't trust the apps notifications. I just go to their official website by typing the address and update my software. Because on Electrum we have seen how scammers were able to send notifications on the apps that force the download of fake software or malware. So always need to verify the official sources. Because it's related to the funds, and we need to be very careful.
