Sudden spikes in event traffic – how are you handling this in Klaviyo?

Hi everyone,

We’re using Klaviyo to track user events and trigger flows, and most of the time things run smoothly. However, during certain campaigns or promotions, we see sudden spikes in events being sent to Klaviyo (for example after emails or social pushes), and it sometimes creates delays or unexpected behavior in flows.

I’m trying to understand how others deal with this in real setups:

  • Do you batch or throttle events before sending them to Klaviyo, or send everything in real time?

  • Have you run into flow delays or missed events during high-traffic moments?

  • Any best practices you’ve picked up for keeping tracking reliable when volumes jump suddenly?

Would love to hear how people are handling this in production, especially from those running larger lists or frequent campaigns.

Thanks in advance!

@danielmartinhq, can you share a bit more detail on the delays and unexpected behavior you’re seeing in flows? Curious to learn more about what you’re seeing here.

I have seen some larger brands use Segment as an intermediary between their site and Klaviyo to throttle / limit the total volume of events that hit Klaviyo at any point in time.
