This feature needs more attention. We need an option to go backwards and bulk import or associate emails with a contact to a deal (i.e. pull in from gmail emails associated with that contact from the past 24 hours, 1 week, 1 month, 1 year, al-time). Sometimes there are emails prior to registering a deal and these emails are lost unless a user manually goes back to link the deals to the contacts.
It would be useful too if we can auto-sync bulk emails to deals as a one time feature when migrating to HubSpot. I.e. pull in all emails on all deals from the associated contacts for a given period (i.e. 1 day, 1 week, 1 month, 1 year, all time) depending on the sales cycle needs. At the moment there is no simple way to migrate into HubSpot without losing all the emails or having to manually link all relevant details or pay a third party app to import emails.
