A good service for mailings. Pay attention! It is intended solely for working with your own databases. If you have a purchased or leaked database from the internet, moderation will not allow you to send out mailings, and your money will be blocked. This is stated in the rules, but few people read them, and then they start to worry, even though they are to blame themselves. When sending to your own database, there are no problems; the emails reach the recipients and do not end up in spam filters. You can track everything in the statistics.
