Many CRMS are integrated with email providers and log + track all emails accordingly. It is much easier to email through gmail or other providers- ie the ability to save drafts and track all correspondence in one space- its too easy to miss emails from clients that contact a gallery directly for instance. I appreciate that an Art Cloud chrome extension / widget in the likes of Hubspot may be too complex to develop (love this system as you can make a contact directly from all new emails) but its crucial to have this functionality for work flow! Salesforce has a system of providing customised email address codes that you could add to all Bcc correspondence which would log all emails sent through a mail provider/email browser into the CRM. This would be quite easy to add- even if the contact does not exist in the system one always knew to add the contact prior to sending an email or forward the email post using the custom address which would add it to the clients activity file. This would help multiple users to also log their emails to the CRM as for instance in Salesforce you could generate each user their own email code easily. PLEASE! Please find a solution! Your in-built mail system is not extensive enough and users are on their email browsers for most correspondence unless using campaigns
