One of the most helpful apps we have added to our Shopify store We have been using Address Validation iO for a while now, and the latest update genuinely improved our workflow. The new email validation feature is extremely helpful. It catches small customer typos before they turn into support issues and it already saved us a few times. The address checks were already reliable, but the update made everything feel even smoother. The improved address suggestions, the country-specific rules, and the new layout customization options helped us block incorrect or incomplete addresses before orders were placed. Since the update, our return-to-sender rate has dropped noticeably. What I appreciate most is how simple and consistent Address Validation iO is. It fixes one of the most common problems in ecommerce: wrong addresses and wrong customer emails. It works quietly in the background, but you immediately see the positive impact. For any store that ships regularly, Address Validation iO honestly pays for itself.

Developer repliedIt is a pleasure to support and provide service for such great Shopify merchants. Thank you very much and continued success! Show more

Sehr einfache Installation und Integration. Selbsterklärend und verständlich für unsere Kunden. Die App korrigiert für uns fast jede zehnte Bestellung, und in Hinblick auf die vermiedenen Rücksendekosten lohnen sich die paar Cent pro Bestellung deutlich! Auch einen kleinen Feature-Request hat das Support-Team zeitnah und genau nach Wunsch kostenlos umgesetzt - danke dafür!

Developer repliedVielen Dank, dass Ihr euch die Zeit genommen habt, Eure Erfahrung zu teilen. Es freut uns sehr dazu beitragen zu können, Eure Kunden noch glücklicher zu machen! Show more

Die App reduziert die Fehler der Kunden deutlich und sorgt somit für korrekte Daten und eine schnellere Versandabwicklung. Es gibt noch ein wenig Luft nach oben, aber auch hier sind die Moving Primates gewillt, ihr System noch weiterzuentwickeln.

Developer repliedLiebes Wundermix-Team, vielen Dank für eure Bewertung und Input. AV.iO wird ständig weiterentwickelt, wir halten euch auf jeden Fall auf dem Laufenden! Viel Erfolg weiterhin. Show more

Ich liebe diese App. Frage mich wirklich warum sie nicht populärer ist. Bei uns wars im Kundenservice immer so ein zeitlicher Aufwand alle Kunden mit fehlerhafter Lieferadresse anzuschreiben und dann zu schauen wann wer geantwortet hat und das ans Lager weiterzuleiten. Das können wir uns jetzt einfach sparen - bin begeistert! + Ich hatte eine Frage bzw. einen Anpassungswunsch und dieser wurde direkt weitergeleitet und in der Software umgesetzt. Besser gehts wirklich nicht.

Developer repliedLiebes After Inject Team, vielen Dank für dieses motivierende Feedback. Freut uns sehr euch unterstützen zu können! Viel Erfolg weiterhin 🚀 Show more

Funktioniert super und der Support ist sehr schnell und hilfsbereit, wenn man etwas anpassen möchte

Developer repliedHerzlichen Dank & viel Erfolg weiterhin! Show more

Addressify is propably the only app, that can solve any address related problems e-commerce stores experience. Be it bad formatting or forgotten details, Addressify directly notifies customers on the thank-you page to edit it or reminds them via an automated e-mail that changes need to be made. All of that, in a true "multi-language" fashion where each visible text on the storefront can be fully customized, for all chosen languages. Looking forward to seeing what is coming next.

Could not enable. Would not work in checkout editor or actual site. Overly expensive per-address pricing. Could not get it to do anything.

Developer repliedSorry to hear that, and thank you for your Feedback. Depending on your Shopify Plan and your staging environment, you may have faced problems, which we would have been happy to solve with you. You are welcome to reach out to our support at any time. Shopify Checkout Extensions and though a validation during checkout are currently only available for Shopify Plus customers. Show more
