Serious question, boost for maximum responses please? Trying to learn something here

Would you be worried that someone was trying to scam you or was fishy if they didn't use a Gmail address for their email? For example, they used Yahoo, Tutanota, Proton Mail, etc?

IMO it doesn't matter what email provider the person uses. What matters is the content of the email and the genuine nature of the content.
The emails of large companies can be mimicked using unicode characters or even manipulated to send malicious mail.
Also I know WHY people use proton mail and other smaller email providers.
Also I got art commissions from people with weird usernames all the time. *shrugs*
