Steps to Implement Kitterman SPF for Your Domain


Step 1: Identify Authorized Email Senders

To initiate the setup of Kitterman SPF, begin by identifying all email servers permitted to send messages for your domain. This includes:


  • Your own mail server if you send emails directly from your domain.

  • Third-party email services e.g., email marketing platforms, CRM systems, cloud-based services.

  • Any other services that send emails using your domain.

Identifying authorized senders allows only verified sources to email from your domain, reducing the risk of spoofing.


Step 2: Access the Kitterman SPF Record Generator

To proceed, visit the Kitterman SPF Record Generator at https://www.kitterman.com/spf.

This user-friendly tool enables you to enter your domain and the email servers you want to authorize, generating the necessary SPF record for you.


Step 3: Input Domain Information into Kitterman SPF Tool

In the Kitterman SPF tool, you will be prompted to provide the following information:


  • Your domain name (e.g., example.com).

  • Authorized sending mail servers (IP addresses or domain names of the email services you use).

  • Any include mechanisms for third-party services (if you use services like Gmail, Microsoft, or other email platforms).

For example, if you are using Google Workspace to send emails on behalf of your domain, you would add include:_spf.google.com to your SPF record.


Step 4: Generate the SPF Record

After inputting the required details into the Kitterman SPF tool, click Generate SPF Record. The tool will produce a properly formatted SPF record based on your input.

Here’s an example of a generated SPF record:

v=spf1 include:_spf.google.com ~all

This example shows that v=spf1 denotes the SPF version, while include: spf.google.com permits Google's mail servers. The term all indicates a soft fail for emails not originating from authorized sources.



Step 5: Publish the SPF Record in Your DNS

After generating the SPF record, the next step is to publish it in your domain’s DNS (Domain Name System) settings. This is typically done through your hosting provider’s control panel.

To publish the record, follow these steps:


  • Log into your DNS provider’s control panel.

  • Navigate to the DNS settings for your domain.

  • Add a new TXT record with the generated SPF value.

  • Save the record.

Once the record is published, it may take up to 48 hours for DNS propagation to complete, depending on your hosting provider.
