"We recently migrated our CRM from Insightly over to Salesforce – we’ll be using Salesforce going forward to manage all our contacts including volunteers, customers, partners, donors, and influencers. We use Mailchimp for sending newsletters and periodic communications to our database of nearly 5000 contacts. We haven’t completed updating and merging our main contact list in MailChimp to reflect new contacts made in Salesforce and our old contacts from Insightly. This task would involve, using the Salesforce/MailChimp integration to merge our lists into one Mailchimp list and creating various segments in that list."
