Need to add more than email sync of only 60 days for previous emails

Being a new Salesmate customer, I learned that when syncing my G Suite email account with SM, it only syncs the previous 60 days which is way too low. It should be a minimum of 6 months. Many other CRM platforms do a lot more than 60 days email syncing. Please extend the email syncing days to a minimum of 120 days.

I am missing thousand of emails I have in my email folders and SM inbox and need to keep reverting back to my Gmail G Suite email folders to access the emails. This is a MUST! It almost makes no sense to me to use the SM email unless I use it for bulk emailing for tagging which is a great feature.
