Review on Email Checker by Craig Shah

We use this tool to check email addresses before sending out our newsletter or other emails that are personal in nature. This has saved us from many spam complaints about invalid email address. It is very easy to setup, simple interface with good documentation available online. I would like if they have more features so we can filter out some of the junk mails as well. The best part is it's free! You cannot go wrong with this product. We were able to save a lot of time by having valid email addresses when sending out newsletters.
