The Power of Integrated Email Testing

Integrating your email testing platform with other marketing tools and data sources can unlock a wide range of benefits:

Connecting Your Email Testing Tool to Marketing Automation Platforms

Integrating your email testing solution with marketing automation platforms like Marketo, Pardot, or HubSpot allows you to create seamless, data-driven campaigns. Here's how to set up the integration:

  1. Generate API keys in your email testing tool and marketing automation platform
  2. Configure the integration using the API keys
    
    // Example: Connecting Marketo to an email testing tool
    const testingTool = new EmailTestingTool('API_KEY');
    const marketo = new Marketo('MUNCHKIN_ID', 'CLIENT_ID', 'CLIENT_SECRET');
    
    testingTool.integration.connectToMarketingAutomation(marketo);
        
  3. Map fields between the two systems to ensure data syncs correctly
  4. Set up automated triggers to launch tests based on marketing automation events
Tip: Use granular segmentation in your marketing automation platform to power highly targeted email tests. Slice your audience based on demographics, behaviors, and engagement levels to optimize content for each group.

Best Practices for Marketing Automation Integration

  • Keep data in sync by scheduling frequent updates via the API
  • Leverage dynamic content blocks in your marketing automation platform to swap in the winning variations from your email tests
  • Set up alerts to notify you of major lifts or drops in key metrics after launching a new test

Leveraging CRM Data for Personalized Email Tests

Your CRM contains a wealth of valuable data about your subscribers that can be used to inform and optimize your email tests. By integrating your email testing tool with your CRM, you can:

CRM Data Point Email Testing Application
Demographic info (age, gender, location) Tailor email content, offers, and creative to specific audience segments
Past purchase history Promote related products; customize offers based on price sensitivity
Website browsing behavior Highlight products or categories the subscriber has shown interest in
Email engagement (opens, clicks) Test alternative subject lines, contents, and CTAs based on past engagement

Implementing CRM-Driven Email Tests

To set up CRM integration for email testing:

Use the API or a native integration to establish a connection between your CRM and email testing tool. Ensure you have the proper credentials and permissions.


// Example: Connecting Salesforce to an email testing tool 
const testingTool = new EmailTestingTool('API_KEY');
const sfAuth = {
  instanceUrl: 'https://example.salesforce.com',
  accessToken: 'SESSION_ID_HERE'
};
const sfConn = new Salesforce(sfAuth);

testingTool.integration.connectToCRM(sfConn);   
        

Identify the CRM data points you want to use for personalization, such as demographics, behavior, and transaction history. Map those fields to corresponding attributes in your email testing platform.

Use the mapped CRM data to create audience segments and dynamically customize email content for your tests. Test things like:

  • Personalized subject lines and preview text
  • Product recommendations based on past purchases or browsing history
  • Targeted offers and incentives aligned to customer segments
  • Localized content tailored to the subscriber's region

After running your email tests, feed the results back into your CRM to enrich your customer profiles. Use the insights to guide future segmentation, content strategies, and lifecycle marketing campaigns. The goal is to create a closed-loop system where data continuously informs optimizations.

CRM Integration Best Practices and Pitfalls to Avoid

Watch Out: Integrating your CRM with an email testing tool can introduce data privacy and compliance risks. Be sure to work with your legal team to ensure you stay compliant with regulations like GDPR and CCPA.

Some best practices when leveraging CRM data for email testing:

  • Start with a small set of high-value data points and gradually expand as you validate results
  • Ensure any personalized content is relevant and adds value for the subscriber - don't personalize just for the sake of it
  • Give subscribers control over their data and communication preferences to build trust
  • Continuously clean and de-dupe your CRM data to maintain accurate subscriber profiles

Implementing Analytics Integration for Email Tests

To connect your email testing tool to an analytics platform:

  1. Ensure your email testing tool supports integration with your chosen analytics platform (e.g. Google Analytics, Mixpanel, Amplitude)
  2. Generate tracking codes in your analytics platform and place them in your email templates, landing pages, and conversion points
  3. Append unique identifiers to email links to tie subscriber actions to test variants
    
    <a href="http://www.example.com?utm_campaign=spring_sale&utm_medium=email&utm_source=newsletter&utm_content=10_percent_off&evar35=TEST_1_VARIANT_A">Shop Now</a>

Some analytics integration tips:

  • Focus on tracking business-critical metrics like revenue, lead quality score, and retention rates.
