According to the latest email deliverability statistics calculated by GlockApps tests, an average of 33% of emails appear in users' spam folders, and every third email is never delivered. The reality is that successfully sending and delivering email requires careful preparation and work.
In this article, we’ll focus on email domain reputation, which is a key italy business email list component in whether your emails end up in your inbox or as spam.
What is email domain reputation?
Email domain reputation is your credit score with your Internet Service Provider (ISP). They use your email domain reputation to determine if your email is trustworthy enough to get into your inbox. ISPs publish e-mail sender guidelines that should be followed by all senders who wish to successfully deliver their mail to ISP users.
When an email arrives, email filters run a number of checks before letting the email pass. If you follow the rules and have a good reputation, you should have no problem. However, if your email reputation is questionable, your emails will most likely be filtered or rejected.

ISPs often reject emails from senders with a history of phishing or spoofing attacks because they are particularly wary of such domains. Therefore, email domain reputation plays a crucial role in determining whether your emails are blocked or reach your inbox.
It's important to remember that all ISPs' email domain reputations are not the same. Each email provider has its own unique algorithm for evaluating your domain reputation, making it a complex and personal aspect of email deliverability.
So the same email sent from the same domain might arrive in your AOL inbox without issue, but Gmail might mark it as spam. This suggests that senders should use a more thoughtful and personalized approach to email marketing to be able to use different providers to contact their customers.
