I rarely leave negative reviews, but my experience with Hunter.io was extremely disappointing. I purchased the platform specifically to save time sourcing professional email contacts. Instead, I spent hours manually correcting spreadsheets, cleaning names, fixing domains, rerunning lists, and going back and forth with multiple customer support representatives just to get usable results. In the end, only about 7% of the results were actually usable. Support themselves acknowledged multiple issues with how the uploaded data was being interpreted, including mismatched company domains, improperly processed names, and rows that were “never going to return anything.” At that point, the software became more manual work than simply doing the research myself. What made the experience worse was the refusal to issue a refund despite the poor outcome and extensive documented support interactions. Instead of resolving it fairly, I was offered account credits and a subscription extension for a service I no longer trust or intend to use. I tried repeatedly to handle this professionally and avoid escalation, but ultimately had to file a chargeback through my bank because I genuinely do not believe the service delivered the functionality or value that was advertised. Very disappointing experience overall. If a product materially fails to perform as expected, refunding the customer should not be this difficult.

I think the UX is strong and when i need to use the tool feel like its always accurate and efficient
