I checked for the first time smtping a couple of months ago before the ltd. Then by chance I figured out that there is an LTD for a new email validation tool, and the offer was interesting.

Now for 2 months, I use it every single day, for new lists and the results are more than satisfying, I'm very glad about the choice.

The instant chat feature is a BIG plus as well. The team seems very motivated for future releases.

Good job guys
