Email marketer from Email Marketing Tips states that If you receive an email from a gmail variant and you are not sure about it, check the headers to find the originating IP address.

Email marketer from Email Hippo explains that one method to validate a domain is valid is to use an email verification API. These tools check the domain's syntax, existence, and MX records, along with testing the email address's deliverability by connecting to the mail server.

Email marketer from StackOverflow responds that for validation purposes, one should check if the domain exists and has a valid MX record, but not rely on a specific list of valid Gmail country codes, as these are not typically used for email.

Expert from Spamresource advises it is important to maintain excellent list hygiene to prevent your emails ending up in the spam folder and to ensure your email deliverability is good. As part of this one of the validation methods that is helpful, is to validate the TLD of the email address. Most valid emails are .com, .org, .net. But not all .com, .org, and .net are valid. You should check the list against a TLD that is likely to be spam, such as country specific domains if you are only expecting people to sign up from US.

Expert from Email Geeks explains that Google has gmail.<all the gTLDs> too, but just for the website, not for email addresses.

Documentation from Google Help explains that when receiving suspicious mail, check the sender's email address is as expected. Gmail marks suspicious emails with a warning that the email comes from a sender that doesn't match the domain they appear to come from. If the 'mailed-by' domain doesn't match the sender's domain then the email has failed authentication.

Documentation from Google Workspace Updates Blog explains that Google sometimes introduces new regional domain endings for specific enterprise customers with specific regional compliancy issues, but these would not be typical Gmail accounts.
