In the realm of email authentication and security, Sender Policy Framework (SPF) plays a dominant role. SPF has become a fundamental tool for verifying the authenticity of email senders and preventing domain spoofing. One of the valuable applications of SPF is its ability to conduct SPF surveys, which provide insights into email delivery and help maintain a strong sender reputation.
In this blog post, we will explore SPF surveys in-depth, and understand their purpose, benefits, and how they contribute to enhancing email security and deliverability.
TABLE OF CONTENTS
What is SPF?
An email authentication system called Sender Policy Framework (SPF) enables domain owners to determine which servers are permitted to send emails on their behalf. By publishing SPF records in DNS, organizations can declare a list of approved mail servers, ensuring that only legitimate senders can successfully deliver emails using their domain. SPF acts as a powerful defense against email spoofing, forgery, and phishing attacks, bolstering email security and trustworthiness.
What is the purpose of SPF surveys?
SPF surveys offer an important tool for monitoring and analyzing the effectiveness of SPF implementation. These surveys involve sending test emails to an organization’s own domains and observing the SPF authentication results. The purpose of SPF surveys is to gain insights into email delivery, identify any SPF-related issues, and assess the overall health of the SPF configuration.
What are the Benefits of Surveys?
Implementing SPF surveys provides several key benefits to organizations:
Identifying SPF Misconfigurations
SPF surveys help detect misconfigurations in SPF records, such as missing or incorrect entries. These insights enable organizations to rectify SPF issues promptly, ensuring email deliverability and preventing false positive rejections.
Monitoring SPF Compliance
Regular SPF surveys help organizations monitor compliance with SPF policies across their email infrastructure. This ensures that authorized servers are correctly aligned with SPF records and prevents unauthorized senders from exploiting the organization’s domain.
Enhancing Email Deliverability
By maintaining a clean and properly configured SPF setup, organizations can improve email deliverability rates. SPF surveys assist in identifying potential delivery issues, allowing businesses to take corrective actions and optimize their email infrastructure accordingly.
How to Conduct an SPF Survey?
To perform an SPF survey effectively, organizations can follow these steps:
Define Survey Parameters: Determine the scope of the survey, including the email domains to be tested, the test email content, and the survey frequency.
Send Test Emails: Generate test emails that mimic typical email traffic from the organization’s domains. These test emails should be sent to various mailbox providers and email security services to evaluate SPF authentication results.
Analyze Survey Results: Analyze the survey results to identify any SPF failures, inconsistencies, or misconfigurations. Pay attention to SPF pass rates, SPF alignment, and potential issues encountered during the survey.
Take Corrective Actions: Address any identified SPF issues promptly. This may involve updating SPF records, correcting misconfigurations, or working with email service providers to resolve delivery problems.
SPF surveys offer an essential tool for organizations to maintain a robust email authentication framework and enhance email deliverability. By regularly monitoring SPF implementation, businesses can identify and address any SPF-related issues, ensuring reliable email delivery, and protecting their domain reputation.
Embracing SPF surveys as part of a comprehensive email security strategy empowers organizations to fortify their defenses against phishing, domain spoofing, and unauthorized email senders.

Q1. Who can benefit from SPF surveys?
Various parties can benefit from SPF surveys. Domain owners can use them to verify and optimize their SPF records, ensuring proper email delivery and safeguarding their domain’s reputation. Email service providers and system administrators can leverage SPF surveys to enhance their spam filtering algorithms and reduce the risk of accepting spoofed or fraudulent emails.
Q2. How often should SPF surveys be conducted?
The frequency of conducting SPF surveys depends on the needs and circumstances of the domain. It is recommended to perform SPF surveys whenever changes are made to the SPF record or when issues related to email deliverability or authentication arise. Additionally, regular periodic checks, such as every few months or whenever major email infrastructure changes occur, can help ensure the SPF policy remains up to date.
