I am on the Retention Report in Mixpanel. For my initial event, I want to do users that triggered two events on the same day (i.e. First App Open & Save Invoice). Then I want to study retention i.e. any event that was triggered on next day for users that triggered both these events on Day 0
Hi jolly t., Please stand by as I search the Mixpanel knowledge base for an AI-powered answer. I normally take about 15 seconds or so. In case AI cannot answer your question, feel free to reach out to Mixpanel support at mixpanel.com/get-support.

To achieve this in the Mixpanel Retention report, you should follow these steps to define your initial event as a combination of two specific actions:
1. Create a Custom Event
The Retention report's initial event slot typically accepts a single event. To represent users who did both "First App Open" and "Save Invoice," you should create a Custom Event.** Go to the event selection menu in the Retention report. ** Select Create New > Custom Event. ** Add both First App Open and Save Invoice. ** Name it something like "App Open & Save Invoice". * Save the Custom Event [Custom Events Overview].
2. Configure the Retention Report
Once your Custom Event is created, set up your report as follows: ** Initial Event (A): Select your newly created "App Open & Save Invoice" Custom Event. ** Returning Event (B): Select "Any Event" (or the specific event you wish to track). ** Filters: To ensure these two events happened on the same day as you specified, you can switch to *Calendar Retention Mode in the advanced menu. This aligns the retention calculation so that all activities within a strict calendar day are bucketed together [Calendar Retention Mode].
3. Analyze Day 1 Retention
Mixpanel will now show you a cohort of users who triggered either of those events in the "Day 0" bucket. To specifically isolate users who did both events on that day, you can: ** Use the Cohort Builder to create a cohort of users who performed "First App Open" AND "Save Invoice" on the same day. ** Apply this cohort as a Global Filter to your Retention report. This ensures the "Day 0" group only includes users who met both criteria [Define User Cohorts; Global Filters].The Day 1 column in your retention table will then show the percentage or count of those specific users who returned to trigger "Any Event" the following day.

The custom event is an OR operation i.e. if either event was done by user then they are considered to be part of the cohort for which the retention is measured. I want an AND operation i.e. i want to measure user retention for users that did BOTH events on day 0 not one or other
Let me check the knowledge base for you again. One moment! đ
I'm sorry, but the knowledge sources do not explicitly mention a way to create an "AND" relationship between multiple events directly within the "initial event" selection of a Retention report or within a Custom Event, as Custom Events are designed as "OR" operations [Custom Events Overview].However, based on the provided documents, you can achieve this "AND" logic for your Day 0 cohort by using a Cohort as a filter: 1. Create a Cohort: Use the Cohort Builder to define a group of users who performed both "First App Open" AND "Save Invoice" within your desired timeframe (e.g., in the last 30 days) [Creating a Cohort via the Cohort Builder]. 2. Apply as a Filter: In your Retention report, click the Filter button and select the cohort you just created. This restricts the report to only include users who meet both criteria [Global Filters]. 3. Set the Initial Event: Select "Any Event" (or one of the two specific events) as the "A" event. Because the global cohort filter is applied, Mixpanel will only calculate retention for users who belong to that "AND" group [Define User Cohorts].For precise "same day" alignment, you should also ensure you are using Calendar Retention Mode in the advanced settings, which buckets users based on calendar days rather than 24-hour rolling windows [Calendar Retention Mode].
