Mailchimp Salesforce Integration Benefits

You can use the Mailchimp Salesforce Integration to:

  • Connect all of your Mailchimp data, such as subscribers, to your Salesforce CRM account and link them to existing contacts and leads.
  • Create new Salesforce leads for email addresses that do not match existing leads, offering your sales team more individuals to contact.
  • Update Salesforce contacts and leads with Mailchimp campaign activities on a regular basis.
  • Get a clearer picture of your marketing engagement operations.
  • Use more targeted content, such as specific digital adverts, to reach out to your audience.
  • To better understand your clients, view all subscriber activity and campaign success information.

What You Should Know Before You Start MailChimp Salesforce Integration Project 

Before carrying out Mailchimp Salesforce Integration there are few points to keep in mind:

  • Salesforce Editions: Professional, Enterprise, Unlimited, Developer, or Performance platform editions are required for MailChimp for Salesforce. If you have a Professional edition of Salesforce, you will need to ask your Salesforce Account Executive to enable API access before installing the Salesforce integration.
  • Integration Approach: In general, there are three ways to connect your CRM to Mailchimp:
    • Through AppExchange’s MailChimp for Salesforce app (also known as MC2SF/MC4SF app),
    • via native APIs and integrations,
    • via Third-Party tools like Hevo.
  • Account Access and Permissions: Also worth noting is that in order to use the Mailchimp Salesforce Integration, you must have a Trailblazer account and your Mailchimp account must have Manager access or higher. You can only connect a single Mailchimp account to a Salesforce account, and you’ll only be able to see Regular Email and RSS campaigns in your Mailchimp Salesforce integration.
  • Testing Options: It’s a good idea to check how successfully you’ve integrated MailChimp with Salesforce before jumping right into using it. Consider which aspects you’ll need to test the most to assure success, such as a test List View, Audience, Campaign, or records. Aside from the aforementioned considerations, keep in mind that the Mailchimp Salesforce Integration entails more than merely installing the app. It’s a complicated procedure that may require customization and setups in Salesforce’s Process Builder or Flow Builder.

Mailchimp vs Salesforce Marketing Cloud

Salesforce Marketing Cloud is a Mailchimp alternative that is built with marketers in mind. Unlike Mailchimp, which is well-suited to startups and small enterprises, Salesforce Marketing Cloud is better suited to larger field sales groups with more complex sales and marketing plans.

If you need a custom-branded email template or custom email automation/segmentation logic for a large number of contacts, Salesforce Marketing will be more capable than Mailchimp. Mailchimp, on the other hand, is a lot easier to use and administer if it’s well integrated.

Mailchimp Pros

  • A large number of ready-to-use templates for usage in each marketing campaign.
  • A real-time capacity to monitor and track the progress of these campaigns.
  • The high level of integration with Facebook, Twitter, and LinkedIn accounts.
  • Affordability and the availability of a free plan.
  • To launch and operate, you don’t need a lot of technical knowledge.

Mailchimp Cons

  • It’s possible that the user interface isn’t always obvious.
  • Customization is difficult.
  • Marketing functionality is limited due to a lack of sufficient documentation.

Salesforce Marketing Cloud Pros

  • The ability to manage newsletter subscriptions and send them out at certain times and dates.
  • Automating the dissemination of newsletters
  • Data sharing and storage in a secure manner
  • The ability to identify and manage the appropriate audience
  • Within a single Salesforce account, all contacts, address information, opportunities, and notes are centralised.
  • Customizability is good
  • It has the ability to sync with other Salesforce Clouds in a seamless manner.

Salesforce Marketing Cloud Cons

  • There is no free plan available.
  • For small firms, there are too many default features that can be confusing.
  • Implementation can take significantly longer than with MailChimp, as it necessitates additional training and optimization work.

How to Update Mailchimp Data in Salesforce

On the Trailblazer Thread, Bob Leaper attempted to fix this problem in the following way:

  • Set up the Audience Fields you wish to collect in MailChimp, such as the Salesforce Account ID and Contact ID.
  • Create a query in Mailchimp for the Salesforce app in the Salesforce platform for the contacts and leads you to wish to add to the Audience. Tags can also be used to organize MailChimp campaigns that have various messages.
  • Run the Salesforce extract as needed and continue with your MailChimp campaigns.

How to Import Leads from MailChimp After the Initial MC4SF Setup

Ron Kiker proposes the following solution to this problem:

  • Navigate to the MailChimp Setup section.

  • Click App Launcher and select Mailchimp for Salesforce.
  • Navigate to the MC Setup Tab.
  • adjust the Data Sync slider to a blue checkmark.
