Why is IP reputation very important?

Sometimes customers sign up for our service and find themselves frustrated by our obsession with ensuring that our IP addresses are taken care of. That means not allowing them to repeatedly, especially knowingly, send emails that are guaranteed to fail delivery (invalid recipients), or to mailing lists that are not verified by double opt in procedure.

Why are we so protective of our IP address reputation?

Well it’s a story that goes all the way back to the day Mailix was born as just an idea. We saw that people couldn’t just send email to recipients and get them there. They were plagued by delivery issues, most often caused by careless neighbors who either sent spam or just flooded junk to major email providers until the IP addresses they used were more associated with bad than good, causing them to be more likely to be rejected by the major providers (Outlook, Gmail, Yahoo, etc). We set out to solve that issue. How can we solve that issue if we let the same problems occur inside of our network that broke the networks that our customers came from? We can’t. So we’re obsessed with success. Yours and ours. We’re all tied together.

You can be sure that as a customer of Mailix we will not allow a bad neighbor to drag down your chances of having your email delivered to a third party. We’re just crazy enough to care about you, and that means looking out for you. Sometimes that means telling you that you’re doing something wrong.

Conclusion

Sending messages to email addresses that do not exist or to email recipients who do not want to receive the message will cause the IP address of your email provider’s mail server chosen for sending to get a bad reputation and as a result will no longer be able to deliver reliably. If this lasts long enough, this IP address can no longer be used to send email messages at all.

We see this very often with large hosting providers that handle the email traffic of all their customers through a central mail server. If only one customer (and there is always that one) sends SPAM mails, the delivery capability of all other customers is severely limited, even though they might just want to send a personal message to grandma.

Mailix uses many IP addresses of best and excellent reputation to send messages. We also monitor them automatically and intervene immediately and also automatically in case of problems.

Please do not (not only at Mailix) deliberately send email messages to email addresses that do not exist or whose recipients do not want to get this message. This makes email better and more reliable for all of us.
