Bounceless
Simple email verification to improve deliverability and boost email marketing metrics. You might not think much about your emails' bounce rates, but they could actually determine how many people see your emails. Internet regulators (such as ISPs and anti-spam groups) set limits for bounces, spam complaints and unsubscribe requests. If you send campaigns to inactive users and exceed these benchmarks, you will show up lower in inboxes and could even have your account suspended by your ESP. All companies that send email campaigns are assigned a sender reputation score. It's a bit like a credit score. If you send a lot of bounced or unwanted emails, this will leave a negative mark on your sender history. Also, just like credit history, once your reputation drops, it can be tricky to build it up again. Verifying your list means that you'll no longer send to dead email addresses.
