Some potential issues you might face when implementing the Mailgun integration app.
1. Authentication and API Key Issues
- Incorrect API Key: Entering the wrong Mailgun API key or using a restricted key can prevent the integration from functioning.
Solution: Ensure you’re using the correct API key with the necessary permissions. Verify the key in your Mailgun dashboard. - Expired API Key: Mailgun API keys may expire or be revoked.
Solution: Generate a new API key in Mailgun and update it in the integration settings.
2. Domain Configuration Problems
- Unverified Sending Domain: If the sending domain isn’t verified in Mailgun, emails won’t be sent or may get flagged as spam.
Solution: Verify the domain by updating the DNS records (SPF, DKIM, and DMARC) as provided by Mailgun. - DNS Propagation Delays: Updates to DNS records may take time to propagate, causing temporary errors.
Solution: Check DNS propagation status and wait for the changes to take effect.
3. Workflow Triggering Errors
- Misconfigured Triggers: Incorrect HubSpot workflow configurations can prevent Mailgun actions from being triggered.
Solution: Double-check workflow triggers, ensuring they align with the intended events (e.g., form submissions, contact property updates). - Missing Contact Data: If the workflow relies on missing or incomplete data (e.g., no email address), emails will fail to send.
Solution: Validate that the required properties are populated in HubSpot before triggering the workflow.
4. Email Template Issues
- Template Errors: If email templates in Mailgun aren’t properly formatted or contain incorrect merge fields, emails may fail to send or appear broken.
Solution: Test email templates and ensure placeholders match the fields available in HubSpot. - Dynamic Content Issues: Mailgun templates may require specific formatting for dynamic data, which could cause errors if not configured correctly.
Solution: Verify the syntax and test with sample data before using templates in workflows.
5. Rate Limiting and API Throttling
- Exceeded Mailgun API Limits: Sending too many emails in a short time may trigger rate limits, delaying or preventing emails from being sent.
Solution: Monitor usage and upgrade your Mailgun plan if necessary to support higher email volumes.
6. Tracking and Analytics Issues
- Event Tracking Not Enabled: If Mailgun tracking settings (e.g., opens, clicks) aren’t enabled, HubSpot may not receive engagement data.
Solution: Enable tracking in Mailgun’s settings and ensure the integration syncs these events with HubSpot. - Delayed Data Sync: There may be delays in syncing tracking events from Mailgun to HubSpot, leading to incomplete reports.
Solution: Allow time for data to sync and verify webhook configurations if delays persist.
7. Common User Errors
- Incorrect Workflow Associations: Users may select the wrong email templates or mistakenly trigger workflows for inappropriate contacts.
Solution: Double-check workflow logic and test it with a small sample of contacts before full deployment.
Proactive Steps to Avoid Issues:
- Test all aspects of the integration in a sandbox or test environment before going live.
- Regularly review logs and error reports to identify and address problems early.
- Document the integration setup process for easy troubleshooting and onboarding of new team members.
