Common Questions

Why isn't my API key working?

Double-check that you've copied the complete API key without any extra spaces. Ensure the key has read permissions for campaign and statistics data. If issues persist, try generating a new API key in your Mailchimp account.

Why don't I see any campaigns or data?

Make sure you have sent campaigns within your selected date range. Some platforms may take a few minutes to update their API data after sending. Also verify that your API key has the correct permissions to access campaign statistics.

What if I'm getting timeout or rate limit errors?

Most email platforms have API rate limits to protect their servers. If you're experiencing timeouts, try selecting a shorter date range or wait a few minutes before generating another report. For large accounts with many campaigns, consider breaking your analysis into smaller time periods.

Is my data secure?

Yes. We only request read-only access to your campaign statistics. We never have permission to send emails, modify campaigns, or access subscriber personal data. Your API key is encrypted and stored securely. You can revoke access at any time from your Mailchimp account.

Can I disconnect my account later?

Absolutely. You can disconnect your Mailchimp account anytime from your Email Calculator settings page. Simply remove the integration and your API key will be deleted from our system. You can also revoke the API key directly in your Mailchimp account.
