The easy to use interface, very good price/value ratio compared to other similar services.Easy integration of different marketing tools like autoresponder, social networks etc.The possibility to verify multiple domains.
I had no problems with this product, but it would be great if they could improve support for large email lists. If you don’t have huge amount of data to clean, this is definitely worth a try as it provides solid results and saves time on manual verification.We are managing email verification for various clients and we can say that this tool helps us save lots of time.
