Openness

How well Klaviyo keeps people informed when something goes wrong.

  • Reports problems openly: 11 posted on its status page in the last 90 days
  • Shows 12 separate parts, so you can see exactly what's affected
  • Keeps people updated: 4.8 updates per problem on average
  • Says what caused the problem: in 10 of 11 problems

Posting small problems openly is a good sign. An app that reports more problems isn't necessarily less reliable than one that reports fewer.

Guide

Klaviyo down? The answer is at the top of this page. Appys checks Klaviyo’s official status page as you arrive, so what you see is never more than a few minutes old. Below is what to check on your side, what to do while you wait, and how to hear when it’s fixed.

Klaviyo down for everyone, or just you?

If the status above says Klaviyo is working normally but it isn’t working for you, the problem is most likely closer to home. Press Is it just me? at the top of the page: your own device and our server both try to reach klaviyo.com, and the answer tells you which side the problem is on.

Then try these quick checks:

  • Open Klaviyo on another network, such as mobile data instead of Wi-Fi.
  • Try a different browser or a private window, to rule out an old cache or a browser extension.
  • Restart your router if lots of websites are slow, not just this one.
  • Make sure your device’s date and time are set automatically: a wrong clock can stop secure connections.
  • Look at your account’s sending or activity log: one campaign stuck in the queue isn’t always an outage.

Klaviyo down? What to do while you wait

  • Check which part is affected. Klaviyo splits its status into 6 parts, listed under What Klaviyo reports on above, so a problem in one may not touch the ones you use.
  • Pause scheduled campaigns if sending is affected, so they don’t go out late or twice.
  • Don’t resend a campaign until it’s fixed and you’ve checked how many actually went.
  • Check your sign-up forms afterwards: new subscribers may not have been saved while it was down.
  • Keep this page open: the status changes by itself when Klaviyo posts the fix, so there’s no need to keep refreshing.

If it drags on and the work can’t wait, the alternatives near the top of this page are other email marketing tools that are working right now.

Why apps like Klaviyo go down

Email sending platforms most often slow down or stop when their sending servers are overloaded, after an update, or when a big inbox provider delays mail. Even big outages are often partial, hitting one feature, one region or one group of users rather than everyone. That’s why Klaviyo can work fine for you while its status page reports a problem, or the other way round.

How Appys checks Klaviyo

Every status on this page comes from Klaviyo’s official status page, where Klaviyo’s own team posts problems and fixes. Its status page covers 6 parts: Composer, Analytics, Platform, Campaigns, API and Flows. Appys reads it whenever someone opens this page and regularly in between, keeps a record of every problem it posts and works out the 90-day uptime from that record. We never change what Klaviyo says, and nobody can pay to change a status or a record.

A quiet status page doesn’t always mean nothing is wrong: some companies post small problems late, or not at all. That’s why this page also shows how openly Klaviyo reports its problems.

How long do Klaviyo outages last?

It depends on what broke. Small problems are often fixed within the hour, while a big outage can take most of a day. The history above lists every problem Klaviyo has posted recently, when each one started and how long it took to fix, so you can see what’s normal for Klaviyo rather than guessing. While a problem is open, the latest update from Klaviyo is shown at the top of this page.
