The best thing about this software it's ease of use, It can extract emails from various sources like Hotmail, Gmail etc., I love how easy it was to get started with using this program as well as its support team whenever i have any issues or questions regarding their services they are very quick at responding back in less than 30 minutes! Nothing so far that would make me dislike working with them but if there were something then maybe having more options for pricing plan could be better? But overall great customer service which makes up for everything else. As mentioned earlier we used to do manual data entry every now and again when doing bulk mailings. Using this product has made our lives much easier by automating all these processes making us focus only on other important things rather than manually entering each one individually.
