IP Reputation Check Hacks to Beat Spam Filters and Blacklists!

According to a report by Validity, 85% of email deliverability issues are related to sender reputation, which includes factors beyond your IP reputation.

If your emails are constantly landing in spam or getting blocked, it could be due to your IP reputation. An IP reputation check can help you find out if your IP address is trusted or flagged by spam filters.

What is an IP Reputation Check?

An IP reputation check helps you see if your IP address is trusted or blocked by others online. It looks at your email sending history, checking for spam or poor behavior.

IP address data is crucial in assessing IP reputation, as it helps monitor the IP's neighborhood and historical network behavior.

If your IP address is linked to sending spam or being on a blacklist for malware, it could stop your emails from reaching people.

7 Essential IP Reputation Check Hacks to Avoid Blacklists

1. Regularly Check Your IP Reputation

To keep your emails from being blocked, you should check your IP reputation often. A poor IP reputation can cause your emails to end up in spam filters or blacklists.

• Use a reliable IP reputation service to monitor your IP address.
• This helps ensure that your mail server is not sending spam or getting flagged by email blacklists.

2. Use IP Rotation to Reduce Risk

When you send a lot of emails from the same IP address, it can hurt your IP reputation.

• To reduce this risk, try rotating your IP addresses.
• IP rotation is when you switch between multiple IP addresses to spread out the sending volume. This helps avoid getting your IP address blacklisted.
• Ensure that the IP address assigned to you by your hosting provider has a clean reputation and is not previously blacklisted.

3. Limit Sending Volumes

Sending too many emails at once can raise red flags.

• It’s important to limit how many emails you send in a short period.
• By lowering your sending volumes, you reduce the chances of being flagged for sending spam.
• Online behavior, including the volume and frequency of emails sent, plays a crucial role in determining the reputation of your IP address.
• This will help protect your IP reputation and keep your emails out of the blacklist.

4. Segment IP Addresses Based on Usage

Not all IP addresses should be used for the same purpose. Segmenting your IP addresses is a good way to manage your email sending. For example, use one IP address for transactional emails and another for marketing emails.

• This helps protect your main IP address reputation.
• It also makes it easier to identify any poor IP reputation issues before they affect your entire system.

5. Monitor Blacklists

If your internet IP gets blacklisted, your emails will likely get blocked.

• An IP reputation lookup can quickly reveal if your IP is flagged for sending spam or malware.
• There are many IP reputation services that provide this monitoring. Utilizing various data sources can enhance the reliability of these services.
• You can set up alerts to stay informed if your IP address appears on any email blacklists.
• This keeps your reputation clean and helps avoid being blocked.

6. Avoid Spam Triggers in Your Content

Content can sometimes cause your emails to be labeled as spam.

• Avoid using too many links, spammy keywords, or suspicious formats. This can trigger spam filters and hurt your IP reputation.
• Establish a secure connection between your email server and recipients helps build trust.
• Stick to clear, trustworthy content, and always follow best practices.
• The goal is to keep your emails from looking like spam to both filters and users.

7. Monitor Feedback Loops from ISPs

Internet Service Providers (ISPs) can send feedback when users mark your emails as spam. This is called a feedback loop.

• Monitoring this feedback helps you understand how your emails are being received.
• If too many users mark your emails as spam, your IP reputation could suffer.
• Regularly review these loops to adjust your email strategy and protect your IP reputation.
• Monitoring your IPs and their performance helps prevent sudden drops in email deliverability.

Conclusion

Regularly performing an IP reputation check is essential to keep your emails out of spam filters and off blacklists. By monitoring your IP address reputation and using the right IP reputation services, you can ensure a better email delivery rate.

Avoiding a poor domain and IP reputation helps your emails reach the right inboxes. Stay proactive, keep your domain and IP clean, and protect your business from being blocked.
