Two Layers of Not-for-syncing Blocklists

Among other features, RG Email Sidebar offers automated saving of Exchange/Office 365 Emails, Meetings/Appointments, and Contacts in Salesforce. To prevent saving of items not intended to be saved in Salesforce, RGES includes two layers of blocklisting based on email address or email domains:

  • Org-wide blocklisting (managed via the Admin panel). This blocklist is used to exclude spam, newsletters, and other unwanted emails from being saved in Salesforce by the users; internal (in-org) domains and addresses are also appended to it
  • User-defined blocklisting (managed via individual Sync settings). This blocklist is used to exclude personal communication and meetings/appointments as well as personal newsletters from being saved in Salesforce

By default, these blocklists are combined for every individual user and users can remove addresses/domains set on the Admin level from the congregated blocklist.


Per customer’s request (option available for Enterprise users only), this behavior can be adjusted so that addresses/domains set by the Admin will be impossible to remove from the blocklist via the users’ individual Synchronization setting



Besides the org-wide and user-defined blocklisting described above, another blocklist feature is configured in RGES. A special global setting blocklists all free email services (e.g.,, etc.) from auto-syncing by default. To change or customize this setting, contact our support team
