Sender IP and Blacklist Details

In the world of email, your sender reputation is everything. It's a key factor that email services use to decide if your email is trustworthy enough to land in the inbox. A crucial part of this is your Sender IP address and whether it's on any blacklists.

What is an IP address?

Think of an IP address as your email's mailing address. When you send an email, it's sent from a specific server with a unique IP address. The receiving email provider checks this address to see if it has a good or bad reputation.

Why Blacklists Matter

Blacklists are simply databases of IP addresses and domains known for sending spam. Many email providers use these lists to block unwanted emails.

For each test you run on Unspam.email, you can see the specific IP address used and if it appears on any blacklists. This is important because you might share an IP address with other senders. If one of them has a bad reputation, it can hurt your deliverability even if your own emails are perfect.

Unspam.email automatically checks your IP against major blacklists. If your IP is flagged, our report will alert you right away. This gives you the information you need to contact your email service provider or take steps to improve your reputation. By monitoring your IP and blacklist status, you can protect your email deliverability and make sure your messages reach their audience.
