I am engaged in spam by soap, but about a month ago I ran into an unpleasant problem - the income from mailings sensitive sagged. Earlier, on average, it was possible to get $ 300-500 from mailing to base of 100,000 mails, after the base burned out only 100-150. I asked around from experts - it turned out 
that the quality of email databases is very important, like it is necessary to periodically validate (clean) the database of sweat boxes from garbage. I started looking for a way out, but in the market for validator services, there are simply horse price tags. To check one base for me - $ 2,500, and of course I have more than one. And, oddly enough, it was in Telegram that I discovered an interesting bot! - I want to show - for many it will become assistant (It was once private) A BOT validator for email databases, from the price i was chocked, 10-20 cheaper than the average service on the market for validating email databases. 
checking speed is very fast!
