Cardin has added support for the CRM platform Less Annoying CRM to Cardin for Gmail. Cardin for Gmail is available to add to your Gmail side-bar in the Google GSuite Marketplace. A free trial of Less Annoying CRM is also available.
Once you have Cardin for Gmail installed, you can add the LACRM Connector to the Cardin for Gmail Dashboard. You can then lookup and edit CRM records without having to leave your Gmail inbox!
