How to Use Checkly for Marketing Automation

Why Use Checkly for Marketing Automation?

Marketing automation relies on a complex ecosystem of interconnected services: email platforms, CRM integrations, landing pages, payment processors, analytics trackers, and A/B testing tools. When any component fails, you lose leads, revenue, and trust. Traditional monitoring often catches failures after customers have already encountered problems.

Checkly solves this by letting you define monitoring as code alongside your marketing infrastructure. Instead of configuring checks through web interfaces, you write TypeScript tests that verify your entire marketing funnel works end-to-end. These checks run from 20+ global locations, catching regional issues before they impact conversions.

For marketing teams, this means monitoring critical user journeys: form submissions, checkout flows, email signup processes, and tracking pixel implementations. When your Black Friday campaign drives traffic to a broken landing page, you'll know within minutes—not hours later when conversion rates tank.

Getting Started with Checkly

Checkly operates on a monitoring-as-code model where checks live in your repository alongside your marketing infrastructure code. You'll need Node.js 16+ and the Checkly CLI to begin.

Install the CLI and create your first project:

```bash npm install -g checkly checkly login mkdir marketing-monitoring && cd marketing-monitoring checkly init ```

The init command creates a project structure with TypeScript configuration, example checks, and deployment settings. Your directory structure will look like:

``` marketing-monitoring/ ├── src/ │ ├── checks/ │ │ └── homepage.check.ts │ └── lib/ │ └── config.ts ├── checkly.config.ts └── package.json ```

Step-by-Step Setup

Configure Global Settings

Edit `checkly.config.ts` to define your monitoring scope and alert channels:

```typescript import { defineConfig } from 'checkly'

export default defineConfig({ projectName: 'Marketing Automation', logicalId: 'marketing-prod', repoUrl: 'https://github.com/your-org/marketing-monitoring', checks: { locations: ['us-east-1', 'eu-west-1', 'ap-southeast-1'], frequency: 5, // minutes alertChannels: ['email', 'slack'], }, cli: { runLocation: 'us-east-1', } }) ```

Choose check locations based on your audience geography. US-focused campaigns should prioritize `us-east-1` and `us-west-1`. European campaigns need `eu-west-1` and `eu-central-1`. Global campaigns benefit from Asia-Pacific locations like `ap-southeast-1` and `ap-northeast-1`.

Monitor Landing Page Conversions

Create a browser check that validates your core conversion funnel. This example monitors a lead generation form:

```typescript // src/checks/lead-form.check.ts import { BrowserCheck, Frequency } from 'checkly/constructs' import { expect } from '@playwright/test'

new BrowserCheck('lead-form-conversion', { name: 'Lead Form Conversion', frequency: Frequency.EVERY_5M, locations: ['us-east-1', 'eu-west-1'], code: { content: ` const { test, expect } = require('@playwright/test'); test('lead form submission', async ({ page }) => { // Navigate to landing page await page.goto('https://example.com/landing'); // Verify key elements load await expect(page.locator('h1')).toContainText('Free Marketing Guide'); await expect(page.locator('form#lead-capture')).toBeVisible(); // Test form submission await page.fill('input[name="email"]', 'test@checkly.com'); await page.fill('input[name="company"]', 'Test Company'); await page.click('button[type="submit"]'); // Verify success state await expect(page.locator('.success-message')).toBeVisible(); await expect(page.url()).toContain('/thank-you'); // Check tracking pixels fired const gtmRequests = page.waitForRequest('*/gtm.js'); const fbPixelRequests = page.waitForRequest('/tr?'); await Promise.all([gtmRequests, fbPixelRequests]); }); ` } }) ```

This check validates that your landing page loads correctly, the form accepts submissions, users reach the thank-you page, and tracking pixels fire properly—critical for attribution accuracy.

Monitor Email Marketing Infrastructure

API checks verify your email service integration stays healthy:

```typescript // src/checks/email-service.check.ts import { ApiCheck, Frequency } from 'checkly/constructs'

new ApiCheck('mailchimp-api-health', { name: 'Mailchimp API Health', frequency: Frequency.EVERY_10M, request: { method: 'GET', url: 'https://{{dc}}.api.mailchimp.com/3.0/lists/{{list_id}}/members', headers: { 'Authorization': 'apikey {{mailchimp_api_key}}' } }, assertions: [ { source: 'STATUS_CODE', property: '', comparison: 'EQUALS', target: 200 }, { source: 'JSON_BODY', property: '$.members[0].status', comparison: 'CONTAINS', target: 'subscribed' }, { source: 'RESPONSE_TIME', property: '', comparison: 'LESS_THAN', target: 2000 } ] }) ```

Store sensitive values like API keys in environment variables. Set these in your Checkly dashboard under Environment Variables: `MAILCHIMP_API_KEY`, `MAILCHIMP_DC`, `MAILCHIMP_LIST_ID`.

Monitor CRM Integration

Verify your CRM webhook endpoints accept lead data correctly:

```typescript // src/checks/crm-webhook.check.ts import { ApiCheck } from 'checkly/constructs'

new ApiCheck('salesforce-webhook', { name: 'Salesforce Lead Webhook', frequency: Frequency.EVERY_15M, request: { method: 'POST', url: 'https://webto.salesforce.com/servlet/servlet.WebToLead', headers: { 'Content-Type': 'application/x-www-form-urlencoded' }, body: 'oid={{salesforce_org_id}}&email=monitor@checkly.com&first_name=Test&last_name=Lead&company=Checkly&lead_source=Website' }, assertions: [ { source: 'STATUS_CODE', property: '', comparison: 'EQUALS', target: 200 } ] }) ```

Deploy and Configure Alerts

Deploy your checks to Checkly's global infrastructure:

```bash checkly deploy ```

Configure alert channels in your dashboard. For marketing teams, Slack integration provides immediate visibility:

1. Go to Account Settings > Alert Channels 2. Add Slack webhook URL 3. Configure alert conditions: fail after 2 consecutive failures from different locations 4. Set recovery notifications to confirm issues resolve

Consider PagerDuty integration for high-revenue campaigns where immediate response matters.

Tips and Best Practices

Use realistic test data: Don't submit dummy leads to production systems. Create dedicated test endpoints or use services' sandbox environments. For email testing, use tools like Mailhog or dedicated test email addresses.

Monitor regional performance: Marketing campaigns often target specific regions. Set up checks from locations matching your audience. European GDPR compliance requires different tracking behavior—verify this with EU-based checks.

Test during traffic spikes: Schedule additional checks during campaign launches. Increase frequency from 10 minutes to 2 minutes when running time-sensitive promotions. Scale back during quiet periods to control costs.

Validate tracking implementation: UTM parameters, conversion pixels, and analytics tags break frequently during deployments. Include assertions that verify tracking requests contain expected campaign parameters.

Monitor third-party dependencies: Marketing automation relies heavily on external services—payment processors, email providers, social media APIs. Create specific checks for each critical integration.

Watch for rate limits: Many marketing APIs have strict rate limits. Space your checks appropriately and monitor for 429 responses. Mailchimp allows 10 requests per second; HubSpot limits vary by subscription tier.

Test mobile experiences: Include mobile viewport testing for campaigns targeting mobile users. Responsive design issues often surface only on specific devices:

```typescript test('mobile form submission', async ({ page }) => { await page.setViewportSize({ width: 375, height: 667 }); // ... rest of test }); ```

Cost management: Checkly charges per check execution. A check running every 5 minutes from 3 locations costs $25/month. Balance monitoring frequency with budget constraints. Critical conversion paths warrant frequent checks; informational pages can run every 30 minutes.

When Checkly Isn't the Right Fit

Checkly excels at monitoring user-facing marketing infrastructure but has limitations for certain use cases.

Real-time analytics monitoring: Checkly checks run at minimum 30-second intervals. For real-time campaign monitoring, dedicated analytics platforms provide better granularity.

Large-scale A/B testing: While Checkly can verify A/B test implementation, it's not designed for statistical analysis of test results. Use dedicated experimentation platforms for variant performance analysis.

Content freshness validation: Marketing teams often need to verify blog posts, product updates, or promotional content appear correctly. Checkly can check for element presence but doesn't excel at content validation across many pages.

Social media monitoring: Checkly doesn't integrate with social media APIs for sentiment analysis or engagement tracking. Dedicated social listening tools provide better coverage.

Complex authentication flows: Some marketing tools use complex OAuth implementations or multi-factor authentication. These can be challenging to automate reliably with Playwright.

If your primary need involves monitoring backend marketing data pipelines, ETL processes, or data warehouse operations, consider infrastructure-specific monitoring solutions instead.

Conclusion

Checkly transforms marketing automation monitoring from reactive to proactive. By defining checks as code, you ensure critical marketing infrastructure stays healthy across all customer touchpoints. The combination of browser-based user journey testing and API endpoint monitoring provides comprehensive coverage for modern marketing stacks.

Start with monitoring your highest-impact conversion paths: homepage to signup, lead forms, and checkout flows. Expand coverage to include email service health, CRM integrations, and tracking implementation as your monitoring maturity grows.

Remember that effective monitoring requires ongoing maintenance. As your marketing infrastructure evolves, update your checks accordingly. Regular review of check results helps identify patterns and optimize both your monitoring strategy and underlying systems.
