Stay Out of Trouble With EasyDMARC’s IP and Domain Reputation Checker

EasyDMARC’s IP/Domain Reputation Checker is a free online email reputation and deliverability analysis tool that performs an IP reputation lookup and domain reputation lookup across major blacklists.

It helps you identify whether your IP or domain appears on email blacklist checkers or spam-tracking databases.

IP and domain blacklists are collections of addresses that have been flagged for sending spam, hosting malware, or engaging in other harmful activity. Being on a blacklist can negatively affect your reputation, credibility, and online visibility.

Use our IP blacklist checker and domain blacklist check tools to monitor your sending sources and take immediate action if they appear in any blacklist. Our IP and Domain Reputation Checker lists the sources in a table and links to them directly. To report a problem, you simply need to contact the blacklist vendor itself and go through the processes on their side.

Reputation Check

Why Reputation Matters

Your IP reputation plays a direct role in whether emails are delivered to the inbox, filtered to spam, or blocked entirely.

Inbox placement depends on trust signals

Mail providers evaluate sending IPs based on past behavior, sending patterns, and authentication results. When an IP is flagged as risky, legitimate emails can be filtered or blocked.

Poor reputation impacts all email types

A damaged IP reputation affects more than marketing campaigns. Transactional and internal emails can also be delayed or blocked, disrupting essential communication.

Strong reputation supports long term deliverability

A healthy IP reputation signals consistent and compliant sending behavior. Over time, this improves inbox placement and reduces the risk of deliverability issues.

Why does your IP reputation matter?

IP reputation is the key to email deliverability. Having your domain and/or sending mail server’s IP addresses in blacklists can negatively impact email deliverability. Building a good email domain reputation boosts trust with ESPs and helps you land in your recipients’ inboxes.

It’s recommended to check your IP and domain reputation regularly, especially if you send large volumes of email or manage multiple domains. A weekly or biweekly check helps you detect potential blacklisting early and resolve issues before they impact deliverability.

Simply enter your domain or IP address, hit the “Check” button, and get instant results. With EasyDMARC’s IP Reputation Lookup tool, you can make sure your domain doesn’t appear in any blacklist or take corrective action if it does.

EasyDMARC combines accuracy, transparency, and ease of use in one powerful tool. It scans multiple public blacklists at once and delivers clear, actionable results in seconds. Instead of vague pass or fail signals, EasyDMARC shows exactly where your IP address or domain is listed and provides direct links to the original blacklist sources so you can understand the impact and take the appropriate next steps.

Your IP reputation is a measure of how trustworthy your IP address is in the eyes of email service providers, spam filters, and other online security systems. A poor IP reputation can result in your emails being marked as spam or blocked entirely, negatively impacting your email deliverability and online reputation.

You can improve your IP reputation in the following ways:

  • Ensure you comply with all local sending laws and regulations. Use SPF, DKIM, and DMARC lookup and authentication protocols to ensure your emails are not spoofed or intercepted.
  • Gradually warm up your IP address by sending an increasingly larger volume of emails over time.
  • Regularly check if your IP address has been added to any email blacklists using our free IP Reputation Check tool. If you find that your IP address is on a blacklist, take action to remove it from the list as soon as possible.

The IP and Domain Reputation Checker scans the most recognized and widely used public blacklists, including major spam-tracking and email security databases. These sources are trusted by internet service providers and email platforms to assess sender credibility. The list is continuously updated to ensure complete and current coverage, giving you the most accurate insight into your online standing.

You need to contact that source to submit a delist request for IP and Domain removal from such a blacklist. The major blacklist companies provided by EasyDMARC’s IP Reputation Checker have information on their websites on how you can remove your domain from their lists. The process is usually straightforward and easy. However, some blacklist operators may ask that you provide proof of your improved email marketing practices and corrective actions to remedy why you were listed in the first place.

The EasyDMARC IP and Domain Reputation Checker is completely free to use. You can perform unlimited checks without creating an account or sharing personal information. It’s part of EasyDMARC’s commitment to making email security and deliverability accessible to everyone, from small businesses to large enterprises.

No. EasyDMARC does not store, share, or reuse the IP addresses or domains entered into the tool. Each check is performed securely and anonymously. The system simply retrieves results from public sources in real time, ensuring that your information remains private and protected throughout the process.
