How to Integrate Mailchimp with Any Platform in 2023

In the world of email marketing, Mailchimp is well-known for its user-friendly interface. Despite the platform’s overall ease of use, some users still wonder how to integrate Mailchimp with another platform. If you’d like contacts from another website to flow automatically into Mailchimp, integrations should be your first consideration. This guide will cover all of the integration options Mailchimp offers, so you can make an informed decision about the best solution for your needs.

Mailchimp-Native Integrations

Mailchimp offers over 300 native integrations through its Integrations Directory. These are pre-built connections with popular platforms like WordPress, Shopify, and Salesforce. Because these integrations are already built by Mailchimp, they’re some of the simplest to use! Just log into Mailchimp, navigate to “Integrations” on the left side menu, and choose the platform you’d like to connect.

Mailchimp-native integrations are quick to set up and easy to use. Many of these integrations can automatically tag subscribers or record the revenue generated by email campaigns. Plus, several of Mailchimp’s native integrations open up additional possibilities for automated campaigns. After you turn on a new integration, take a look at Mailchimp’s pre-built journeys to see if any new options have become available. 

For less tech-savvy users, Mailchimp Native integrations are typically the best option. Plus, you can always work with a Pro Partner to walk you through the process.

Basic Mailchimp Integration via API Key

For more advanced users, integrating Mailchimp using an API key is a powerful option. This method provides granular control over your data and allows you to automate tasks like adding and updating subscribers. You can even segment your audience based on specific behaviors or data points from your platform.

Pro Tip: Pure Firefly email marketing offers both basic and custom API integrations, ensuring your Mailchimp setup aligns perfectly with your business goals.

How to Integrate Mailchimp Using Zapier

Sometimes, Mailchimp’s native options aren’t giving you what you need. A third-party integration platform may be necessary to bridge the gap between Mailchimp and another app. Zapier is one of the best of these third-party platforms. Using Zapier, you can automate the flow of contacts from Mailchimp to your other online platforms and vice-versa. For instance, when a new customer joins your online store, Zapier can automatically create a matching contact in Mailchimp.

Zapier is a no-code option for integration, so it’s great for people with limited technical skills. If you need a helping hand, consider a training call with an email specialist.

Using Webhooks to Trigger Real-Time Actions in Mailchimp

At the more advanced end of the technical spectrum, webhooks allow Mailchimp to post automatic updates onto your other online platforms, or vice versa. In the simplest terms, webhooks send a kind of digital signal between platforms. Whenever a specific event occurs on your platform, like a user signing up, a webhook sends out a signal to trigger the corresponding action in Mailchimp, such as adding the user to your audience.

For more info on Webhooks, consider watching Mailchimp’s free Webhooks webinar hosted by Kristy McCarley in 2023. Webhooks can be challenging for users not familiar with HTTP programming, so consider working with an email expert to get everything set up correctly.

Custom API Development: Tailoring Integration to Your Needs

In some cases, you might have unique requirements that go beyond Mailchimp’s typical integration capabilities. That’s where custom API development comes into play. With a custom API, you can build a solution tailored precisely to your needs, ensuring a seamless flow of data between your platform and Mailchimp.

Custom API development requires a high level of technical expertise and can be a lengthy process. This makes them a better fit for organizations with large budgets and highly specific integration needs. If you’re curious about what possibilities API development could open up for you, contact us for more information

5 Essential Tips for an Effective Welcome Series in 2023

First impressions last a lifetime. In email marketing, a welcome series is your chance to make a good one! This automated series is an important tool for building relationships with your audience and turning subscribers into loyal customers or supporters. Here are 5 tips for creating an effective welcome series:

1. Make a Great First Impression

Your welcome series is the first impression that your subscribers will have of your brand, so it’s important to make it a good one. Use a clear and engaging subject line to entice your subscribers to open the email. Then, use a well-designed template that’s easy to read and clearly reflects your brand. Don’t forget to include a clear call-to-action (CTA) that encourages subscribers to engage.

2. Let the Data Guide You

When creating your welcome series, let the data guide you. Use information about your subscribers to create personalized content that speaks to their needs and interests. If you’ve sent emails before, use previous campaign analytics to inform your decisions about what to include in your welcome journey. Pure Firefly’s email marketing experts can help you analyze your data to create targeted content that resonates with your audience.

3. Get the Timing Right

Timing is everything when it comes to your welcome series. It’s essential to send frequently enough to stay top-of-mind without overwhelming your subscribers. Optimal timing may vary depending on your industry and audience, but many marketers find success with a 1-2-3 strategy. 

In this strategy, the first welcome email is sent immediately, the second email is sent one day later, the following two days later, and all the remaining emails are sent three days apart. Contact Pure Firefly to learn how this strategy might work for your own welcome series.

4. Save Sales for the End

Welcome series can be incredibly helpful in generating sales. One study by Experian found that welcome emails generate 3 times higher revenue and transactions than regular promotional emails. However, don’t make the mistake of trying to sell too soon in your welcome series. Your subscribers are just getting to know your brand, so focus on building a relationship before making a sales pitch. 

If you offer a free giveaway or discount in your signup form, provide that immediately, and then turn your attention to more educational content about your organization. Help subscribers trust and appreciate your brand before nudging them towards a sale.

5. Tell Your Story

Your welcome series is an opportunity to tell your brand’s story and share your values with your subscribers. Incorporating storytelling in a welcome automation can help tie all the emails together. Stories to focus on may include:

  • How & why your business was founded
  • Someone your organization has helped
  • Your founder’s bio 
  • A story about the city/town/locality where you’re based
  • A major event you’ve hosted

Adding a personal touch to your welcome series can set you apart from your competitors and build trust with new subscribers. If you’re not sure how to incorporate storytelling into your welcome journey, consider working with an email marketing agency like Pure Firefly.


When in Doubt, Work with Pure Firefly

Storytelling, strategic timing, and data-backed design can all improve your welcome series. However, many brands don’t have the time or expertise to invest in an exceptional welcome series.

3 Email Automations for Agile Marketing

In a time where inboxes are more crowded than ever, email automation can help you break through the noise. Automated emails engage subscribers at key points in their relationship with your brand, business, or nonprofit organization. By responding to subscriber behavior with email automations, you can create a robust & effective email marketing strategy.

Build a Welcome Email Automation

You’ve likely seen it 100 times. You’re browsing your favorite online store, and a pop-up offers 10% off when you subscribe to their emails. How would you feel if that pop-up wasn’t followed by the 10% off it promised? Email automation helps businesses deliver on their promises, building trust with new subscribers.

A welcome email is one of the simplest forms of email automation and one of our most-requested services. When a subscriber signs up, a welcome email should greet them. This email encourages new subscribers to engage, often with a promotional offer. However, welcome emails aren’t just for online sellers.

Welcome automations can help all kinds of organizations nurture positive relationships with their subscribers. An effective welcome series describes the emails a subscriber will receive, then dives beneath the surface. Woo subscribers with your company’s heartwarming origin story, or demonstrate your nonprofit’s impact with news from the communities you serve. The choice is yours, and advice from an email marketing expert can help you build the most effective strategy.

Use Automations to Reward Loyalty

Experienced business owners and nonprofit leaders know that loyalty is key. Use email automations to nourish your most loyal audience members – whether they’re avid online shoppers or monthly donors passionate about your cause.

To set up email automation rewarding customer (or donor) loyalty, consider which actions you’d like to encourage. Your email automation may be triggered when…

  • A customer completes their 100th purchase
  • Someone donates a cumulative amount over $1000
  • A subscriber opens every email you’ve sent in the past 3 months

If you’re using Mailchimp’s customer journeys builder to create your automation, some triggers will require an integration with an online store. You may also be able to create a workaround using tags. Consider consulting a Mailchimp Pro Partner to learn more.

Create Abandoned Cart Automations

Well-timed email automations help customers cross the finish line, so you can deliver on every sale. Set up an abandoned cart automation to reach subscribers when they put a product in their cart but don’t buy it. Abandoned cart emails boost sales, and keep your brand at the top of your subscribers’ minds.

If you’d like to use Mailchimp to create an abandoned cart automation, you’ll need to use an integration. Browse Mailchimp’s integrations to ensure your selling platform is compatible. Especially tech-savvy email marketers may also use Webhooks to set up a custom connection.

Pure Firefly Uses Email Automation Every Day

Whenever we take on a new client, email automation is a major talking point. We tailor every automation to our client’s goals and incorporate several rounds of review to ensure all automated emails are up to their brand standards.
