Email list reached end of flow, but I added more emails

Hey ​@highriskfitness 

In Klaviyo, once a profile reaches the end of a flow, they exit it completely. If you add new emails later, those contacts won’t automatically go back in to receive them. New subscribers entering the flow from now on will receive the full sequence including the emails you just added, but past profiles will not.

If you want those past contacts to receive the new emails, you have a couple of options.

Option 1: Back-populate the flow

Klaviyo has a back-populate feature that lets you retroactively add people who previously qualified for the trigger back into the flow. When you do this, Klaviyo will queue them based on the flow timeline and they’ll skip any emails they already received. So go to your klaviyo flow and click as shown below

and then you can select where in the flow you want to add those profiles. at the beginning or throughout the flow. since your profiles already received previous email, the suggested option for you should be to add “throughout the flow”. make sure to add time delays accordingly.

Option 2: Send a campaign instead
Another common approach is to create a segment of people who already completed the flow and send the new email(s) as a campaign. This is often simpler and gives you more control over timing and targeting. so create a segment of profiles who are in your list and received emails from this flow and send a campaign to that segment.

Pro-tip:
When building flows that may expand later (like welcome series), it helps to include a time delay at the end of the sequence. That keeps profiles “waiting” in the flow a bit longer, which gives you flexibility to add new steps without losing everyone who already passed through.

I hope this helps and thank you for sharing your question here in the community. If you are still stuck, feel free to schedule a call with us.
