Practical ways you can use Buffer and Mailchimp
Share Buffer posts with Mailchimp subscribers
When you add a new idea item in Buffer, Zapier automatically creates a draft campaign in Mailchimp to share that content with your email subscribers. This streamlines the process of reusing social content for email campaigns, improving marketing consistency and saving time for other tasks.
When a new subscriber joins your Mailchimp audience, Zapier adds a new idea in Buffer for potential social media posts. This helps marketing teams smoothly align email and social media efforts, and maintain up-to-date, engaging content across channels.
