Senderbase lookup email
Senderbase is a reputation system developed by Cisco Systems that tracks the sending behavior of email senders, including IP addresses, domains, and mail servers. The system assigns a reputation score to each sender based on various factors, such as:
- Spam complaints: The number of spam complaints received about emails sent by the sender.
- Bounce rates: The percentage of emails that are bounced back to the sender due to invalid or non-existent email addresses.
- Abuse reports: The number of abuse reports received about emails sent by the sender.
- Delivery rates: The percentage of emails that are successfully delivered to recipients' inboxes.
You can look up an email sender's reputation on the Senderbase website using the following methods:
Method 1: Using the Senderbase website
- Go to the Senderbase website at www.senderbase.org.
- Click on the "Lookup" tab at the top of the page.
- Enter the IP address, domain, or email address of the sender you want to look up.
- Click the "Lookup" button.
- The website will display the sender's reputation score, along with other information such as the number of spam complaints, bounce rates, and abuse reports.
Method 2: Using the Senderbase API
- You can also use the Senderbase API to look up a sender's reputation programmatically. The API provides a JSON response with the sender's reputation score and other information.
- To use the API, you need to register for a free API key on the Senderbase website.
- Once you have an API key, you can use the following URL to look up a sender's reputation:
https://api.senderbase.org/v1/lookup?ip=<IP_ADDRESS>&key=<API_KEY>
- Replace
<IP_ADDRESS>
with the IP address of the sender you want to look up, and<API_KEY>
with your actual API key. - The API will return a JSON response with the sender's reputation score and other information.
Example output
Here is an example of what the output might look like for a sender with a good reputation:
{
"reputation": 90,
"spam_complaints": 0.1,
"bounce_rates": 0.5,
"abuse_reports": 0,
"delivery_rates": 95
}
In this example, the sender has a reputation score of 90, which indicates a good reputation. The spam complaint rate is low (0.1%), the bounce rate is moderate (0.5%), there are no abuse reports, and the delivery rate is high (95%).
