I built a system using the gmail api’s, to view the emails and attachments as a third party. It was working fine the first month ,after that my acount used to login to the specific gmail account is blocked, recieving a 429 error other account can get in. Is there a way to remove the read and writes limit of gmail email or to gives permanent and unlimmited acces to the email get rid of the 429 error.

I tried gmail premium , rewriting my http req. Not seeing anything I can to in the google dev screens. Also a request from goolge support. Is there a way to resolve the error or is it just wait to use, if so are there any other email options
