How do you calculate activation rate by signup week?

Export your Mixpanel users and events, plus your activation event rules. The workflow matches users to events, keeps the activation events, then calculates the share of new users who activated within 7 days of signup by signup week.

Weekly Activation Rate: questions

What export should I use?

Use the exported users file and events file from Mixpanel, plus a file that lists your activation event rules. The workflow reads those exported files and uses the rules to find the right events.

What happens to rows that do not match the rules?

Rows that do not match are left out of the activation count. Only rows that match the user key, event key, and activation rules are used in the final result.

How do I change the activation rules?

Edit the rule words in your rules file, then rerun the workflow. You can change which events count as activation and the 7 day window logic by changing those rules.
