Zeruh shuts its email verifier on 17 November and deletes all data

9 November 2026: Zeruh, an email verification service with a web dashboard and an API, will close on 17 November 2026, and its notice says all account data will be permanently deleted at that point. The notice was last updated on 9 November, which leaves customers eight days to pull their results, ask for money back and point their sign-up forms and scripts at another verifier.

Not yet independently verified. This rests on Zeruh's own shutdown notice, read on 9 November 2026, and we found no independent report of the closure. The notice does not say who runs the service or where it is based. We will update this when it can be confirmed, and remove this note.

What has already stopped

New registrations closed with immediate effect, along with new payments, subscriptions, plan changes and credit purchases. Existing accounts keep working. Until the closure customers can sign in, use the dashboard, run single and bulk verifications and call the API, spending whatever credits they have left. With purchases closed, an account that runs out before the 17th has no way to top up.

Recurring plans will not renew after 17 November and can be cancelled from the billing page, with remaining credits kept for the rest of the notice period.

The only reason given is focus: the company says it wants to concentrate on its other two products, Maileroo and CampaignLark. The notice gives no customer numbers, and it does not say whether either product will take Zeruh customers across.

Refunds have to be asked for

Money does not come back by itself. A customer who wants a refund for unused credits, or for the rest of a subscription already paid for, has to use the contact page and give the email address on the account and the invoice or transaction reference. Requests must arrive by 17 November.

Each request is reviewed individually, so the notice promises a process and not a payment. Approved refunds go back to the original payment method and can take up to ten business days to appear.

What to export, and what will break

Every completed bulk verification can be downloaded as a CSV from the dashboard, and results can also be pulled through the API. On 17 November the service stops and verification results, uploaded lists and API keys are deleted, with no recovery. The notice calls that date the final day to export but gives no hour, so finishing a day early is the safer plan. It describes downloads for results only, so anyone whose original lists live solely in Zeruh should check what can be retrieved.

The less visible risk is in the integrations. A sign-up form or a list-cleaning job that calls the Zeruh API will start to fail once the key is gone. Depending on how that call was written, the failure may block genuine sign-ups or let unchecked addresses through, so teams should find every place the key is used and test what happens when the call does not answer.

Where a replacement might come from

Our catalogue holds 16 email verification tools, among them NeverBounce and Kickbox. Zeruh does not have a listing with us. Buyers moving in a hurry should compare how long each provider keeps uploaded lists, as this closure shows what happens to them when a service ends.
