It's possible now to integrate your MailChimp account into Salestrekker. This will allow you to easily transfer contacts from new Deals to your mailing lists. You can apply filtering options in Salestrekker and export contacts to existing lists in MailChimp or create new ones right there on the spot.
To activate, go to Settings > 3rd party applications and at the bottom you will see MailChimp icon with the switch to turn on integration. When turned on you will be prompted to enter your MailChimp account details.
Turning 'Automatically synchronise contacts to:' option will allow users to choose a list in MailChimp where new contacts will automatically be synced to MailChimp.
