I liked that it kept me updated on my leads as they came in. It also allowed me to filter by company size, which was helpful when I had a lot of leads to go through. I can't think of anything I disliked about the product. I would highly recommend this service to other businesses. I do not have any experience with Mail Hunter but everyone is always asking for referrals. So I thought I'd share what I've heard from others. We were looking for a way to manage our database of leads without having to spend hours going through each one. MailHunter seemed like exactly what we needed. They send you an email every time someone opens your message, which helps us keep track of all of our leads. It has been very effective for us.
