Why Mailerlite Automation May Not Be Working (Possible Causes):

Your Mailerlite automation hiccup could be due to various reasons.

Let’s dive deeper into why Mailerlite automation may not be working:

1. Misconfigured Settings:

  • Trigger Settings: Check if the automation triggers are correctly set. For example, if you want an email to send when a subscriber joins a list, ensure this trigger is properly configured.
  • Conditions: Verify that any conditional rules you’ve set align with your goals. Misconfigured conditions can prevent emails from being sent to the right audience.
  • Actions: Ensure your desired actions, like sending emails or adding subscribers to segments, are correctly specified within your automation.

2. Technical Glitches:

  • Platform Issues: Keep an eye on Mailerlite’s status updates for platform-wide problems. Technical issues on their end, such as server downtime or system maintenance, can disrupt your automation.
  • Browser Compatibility: Ensure you’re using a compatible browser, as some features may not work optimally in certain browsers.

3. Subscriber List Issues:

  • Cleanliness of Lists: Check your subscriber lists for outdated or incorrect email addresses. These can lead to email bounces, causing automation failures.
  • Segmentation: If you’re using segmentation in your automation, confirm that your subscribers are correctly segmented to receive the intended emails.

4. Content Errors:

  • Email Content: Review the content of the emails within your automation. Ensure there are no broken links, missing images, or formatting issues that might prevent the emails from being sent correctly.
  • Spam Triggers: Avoid using spammy language or excessive exclamation marks in your email content, as this can trigger spam filters and prevent email delivery.

5. API or Integration Problems:

  • Integration Health: If your automation relies on third-party integrations, verify the health of these connections. Ensure they are up to date and functioning correctly.
  • API Key Validity: Double-check that your API keys are valid and haven’t expired. Invalid keys can disrupt data transfer between systems.

6. Automation Volume:

  • Rate Limiting: Mailerlite may have rate limits on the number of emails you can send in a specific time frame. Exceeding these limits can lead to automation delays or failures. Monitor your automation volume to stay within these limits.

7. Account Limitations:

  • Account Type: Check if your Mailerlite account type aligns with the volume of emails you’re trying to send. Different account tiers have varying sending limits.
  • Billing: Ensure your account is in good standing, and payments are up to date. Account suspension due to billing issues can disrupt automation.

By addressing these specific points, you’ll be better equipped to diagnose and resolve why your Mailerlite automation isn’t working, helping you get your email marketing back on track.

Troubleshooting Steps:

Now that you know what could be causing the issue, let’s roll up our sleeves and get to work.

Here’s how to test your automation to ensure it’s back on track:

  • Verify Settings: Double-check your automation settings, including triggers, conditions, and actions.
