As you can see our service is getting more popular and people are trying to spam comments on this page.
Our email validation service is Free! And also it provides the log of the communication between the service and recipient SMTP.
But there are still some disadvantages of using validation services.
1. You can't validate 100% of addresses without sending a message.
2. You can't validate too many addresses if you don't want to blacklist your IP and harm your deliverability
3. You still need to process bounce responses to clean your list so pre-validation is useless.
We strongly recommend to use bounce processing for your email marketing campaigns. Our Email Marketing Solution
processes bounce responses automatically. You can specify the max number of allowed hard and soft bounces.
