There are clients who receive a lot of emails from customers who are neither contacts, leads nor accounts in CRM. When responding to the emails, they are forced to manually resolve unknown emails by creating them in CRM which is time consuming and not really friendly with customers. The emails at time have more than 10 recipients on CC and you find agents responding to hundreds of emails per day.

My suggestion is to introduce a way which will allow auto creation of contacts or accounts and associate them to the emails. This will give clients a better experience dealing with emails from CRM.

NB: The client base increases day by day and thus the number of times new email addresses will emerge.
