Klaviyo Account Disabled or Flagged for Review After an Import: What Klaviyo Checks and What to Fix

If the notice says the account is disabled, it's a review, not a ban: answer the compliance team, clean the uploaded list while you wait, and reschedule anything that was cancelled. Klaviyo says to expect feedback within 1 business day. If the notice says suspended, it's a failed payment, and paying the invoice re-enables the account automatically.

Which state you're in

Notice	Cause	What lifts it
Disabled: flagged for review	Verification and compliance check, usually a new account's first send to an uploaded list	Compliance team approval; feedback expected within 1 business day
Disabled after campaign alerts	Repeated high hard bounces, unsubscribes or spam complaints	Details go to the primary account owner by email
Suspended	A payment couldn't be processed	Paying outstanding invoices; allow up to 1 hour after updating the card
Sending stopped at plan limit	Not a suspension	Upgrade, flexible sending, or the next billing cycle

While disabled or suspended, Klaviyo sets flows to manual and stops updating segments; it restores the flow actions to live when the account is re-enabled. After a review is approved, campaigns cancelled during it need to be rescheduled.

Why an import triggers it

Klaviyo's anti-abuse article explains the logic: a few hard bounces are normal, but inbox providers read a large number as a sign the addresses were bought or scraped. Klaviyo's terms don't allow bought lists. And imports don't trigger double opt-in, so nothing between your CSV and the first campaign checks that the addresses are real or that the people asked for your mail. Klaviyo's own advice is to review imported contacts before sending to them.

Step by step

1. Reply to the compliance team with how the contacts were collected: store checkout, signup forms, your previous email platform. Klaviyo's suggestions for avoiding review include integrating your ecommerce platform and your previous ESP and keeping business and billing details accurate.
2. Export the uploaded list and check it before anything else goes out: the Klaviyo list cleaner takes a profiles export, or upload it on the verify page. Remove invalid results; keep risky and unknown out of the first campaigns.
3. Bring over suppressions from your previous platform so unsubscribes and old bounces don't get mailed again.
4. Build an engaged segment that requires email consent and recent engagement, as Klaviyo recommends, and send to it first. Opening an email isn't the same as subscribing.
5. Turn on double opt-in for new signups.
6. Reschedule the campaigns that were cancelled, starting with the engaged segment, then widen it.

Honest limits

Verification only answers whether an address can receive mail. It doesn't show consent, so it won't fix unsubscribe or complaint alerts on a list people didn't sign up for. Some results stay risky or unknown: catch-all domains accept any address and some providers don't answer clearly. And Klaviyo doesn't publish a bounce rate that triggers review, so treat any number you read elsewhere as a guess. If the alert came after a big send, what to do after a high bounce rate covers the first 48 hours. For the routine version, see how to clean a Klaviyo list.
