Using Online Tools

How Do I Check My SPF?

Checking your Sender Policy Framework (SPF) record ensures your emails aren't marked as spam. There are several ways to do this:

Many free online tools allow you to quickly check your SPF record. These tools typically require you to enter your domain name and will then display the SPF record and any potential issues. Examples include:

• MXToolbox: https://mxtoolbox.com/spf.aspx - This tool provides a comprehensive SPF record check and validation.
• EasyDMARC: /spf-lookup - EasyDMARC offers a straightforward SPF lookup tool.
• RedSift: https://redsift.com/tools/spf-checker - Another free SPF checker that provides a quick and easy way to validate your SPF record.
• SPF-Record.com: https://www.spf-record.com/spf-lookup - This website provides an SPF lookup analyzing your record for errors and security risks.
• Mimecast: https://www.mimecast.com/products/dmarc-analyzer/spf-record-check/ - Mimecast's SPF record check tool displays the record and identifies errors.

Using Command-Line Tools

For a more technical approach, you can use command-line tools like dig or nslookup.

1. Open your terminal or command prompt.
2. Type in dig txt domain.com or nslookup -q=txt domain.com, replacing domain.com with your actual domain name.
3. Click "Enter" to execute the command. This will return a list of TXT records associated with your domain.
4. Look for the TXT record that starts with v=spf1. This is your SPF record.

Example using nslookup:

nslookup -type=txt example.com

Checking Through Your Domain Provider

If you manage your DNS records through a provider like Microsoft 365, you can often find your SPF record in their control panel. For example, within Microsoft 365:

• Sign in to the Microsoft 365 admin center.
• Navigate to settings > domains.
• Select your domain.
• Look for the DNS records section, specifically checking for TXT records related to SPF.

Remember to always replace "domain.com" with your actual domain name. These methods allow you to check your SPF record and ensure your email delivery and sender reputation are optimized.
