Restricting contact creation

Restricting contact creation

Hi all!

I am looking to use Zoho Desk in a part of the business that takes end user enquiries. These are generally single interactions, and not linked to an account name. 

As Desk is Account centric, has anyone designed a way to manage these incoming emails without creating thousands of additional contacts? Or is there a way to purge the contacts regularly?

I have set up a rule on create to change the account contact and account name to an internal one but I think the contact is still made as part of the ticket creation process.

Keen for any ideas. 

Thanks, Wendy
