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:

  1. Spam complaints: The number of spam complaints received about emails sent by the sender.
  2. Bounce rates: The percentage of emails that are bounced back to the sender due to invalid or non-existent email addresses.
  3. Abuse reports: The number of abuse reports received about emails sent by the sender.
  4. 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

  1. Go to the Senderbase website at www.senderbase.org.
  2. Click on the "Lookup" tab at the top of the page.
  3. Enter the IP address, domain, or email address of the sender you want to look up.
  4. Click the "Lookup" button.
  5. 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

  1. 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.
  2. To use the API, you need to register for a free API key on the Senderbase website.
  3. 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>
  4. Replace <IP_ADDRESS> with the IP address of the sender you want to look up, and <API_KEY> with your actual API key.
  5. 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%).
