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.

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!

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