I am 100% sure that font is Roboto, while the rest of the email is written using Helvetica. This is not a throwaway, I just registered.
Okay this is just ridiculous. Have you tried searching Google for the string that you think is forged?
Try searching for the following, taken from the "fake" portion of the email: "based on your high usage it appears you are eligible for volume pricing discounts, enterprise-grade customer support, and/or offline contracts"
The very first hit is one of Google's pricing pages for their Maps platform:
https://cloud.google.com/maps-platform/user-guide/pricing-ch...
Which says (highlight added by me):
When do I need an Enterprise account?
Businesses with high-volume usage who are looking for volume pricing discounts,
**enterprise-grade** customer support, and/or offline contracts should contact
us about setting up an Enterprise account.
EDIT:
The font used on Google's pricing page is Roboto, which means that the discrepancy is Google's fault as someone obviously did a bad copy/paste job when preparing emails for clients.
If nothing else, you have a good eye for fonts I guess.
Care to retract your accusation now?
