Yes, it obviously does. Gmail is an ad-supported
emailing service. Gmail scans and analyzes the email contents of every user. They
have automated software for this purpose. The scanning and analyzing is done
basically to check the viruses and malwares to provide a great user experience but
as it is ad supported, tailored ads pop up according to the email contents of a
user
The simple logic is to rev up the
advertisement revenue as it doesn’t charge a single buck from its users until
they have opted for paid Google accounts. However, this transparency is limited
to the service provider only. No advertiser has any right to access a Gmail
user’s account without the permission of the account holder. A user can stop
seeing the personalized ads by changing the ad settings in Gmail.
