How does the event reaction work?

​@Ann-Harriet 

The email is sent immediately when someone clicks. The 7-day timeout only applies to people who do not click within 7 days — they will follow the timeout path after that period. Official docs: https://experienceleague.adobe.com/en/docs/journey-optimizer/using/orchestrate-journeys/about-journey-building/reaction-events 

If your goal is instead: “Send the follow-up email 7 days after the click” then you should configure it like this:

1. Email #1
2. Reaction event (“clicked”)
3. Wait activity = 7 days
4. Follow-up email

One important best practice from the docs is that place the Reaction event immediately after the email activity and do not put a Wait activity before the Reaction event, or clicks/opens may be missed.

​@Pulkit_Jain_  Thank you for your response.

I would like everyone who has clicked to receive an email on the same day. How can I set this up in the journey?

If I use a wait step of 7 days, the email will be sent at different times depending on when each person clicked the email. Some will receive it on day 7, while others on day 11. I cannot find any functionality that allows me to choose a specific time for an email to be sent within a journey.
