SPF Multiple Records Warning: Why You Must Fix It

As a SaaS founder, marketer, or tech person managing email sending, you know the importance of getting your emails into the inbox. But there’s a lurking issue that can sabotage your efforts: having multiple SPF records. This is not just a minor annoyance. It can lead to delivery failures and impact your sender reputation. Let’s dive into why this happens and how to fix it.

Understanding SPF Records

Sender Policy Framework (SPF) is a DNS record that specifies which mail servers are allowed to send emails on behalf of your domain. When an email is sent, the receiving server checks the SPF record to verify the sender. If there are multiple SPF records for your domain, it creates confusion. The receiving server may not know which record to follow, leading to potential delivery issues.

The Problem with Multiple SPF Records

Having more than one SPF record can trigger a failure in the SPF check. Here’s what happens:

  • The receiving mail server queries your domain for SPF records.
  • It finds multiple records.
  • The server gets confused and may reject the email or mark it as spam.

This can hurt your inbox placement rates and your overall email deliverability. You might not even realize it until you see a drop in engagement or an increase in bounce rates.

Diagnosing the Issue

First things first, you need to check if you have multiple SPF records. You can use the InboxGreen checker to quickly identify issues with your SPF records. Here’s how to do it:

  1. Go to the InboxGreen checker.
  2. Enter your domain name.
  3. Review the results for SPF records.

If you see more than one SPF record listed, it’s time to take action.

Fixing Multiple SPF Records

Now, let’s get into the nitty-gritty of fixing this issue. Here’s a step-by-step guide:

Step 1: Identify All SPF Records

Use a DNS lookup tool to find all SPF records associated with your domain. You can use command line tools like dig or online tools. For example:

dig TXT yourdomain.com

Look for lines that start with v=spf1. Make a note of each one.

Step 2: Consolidate Your SPF Records

Once you have identified all the SPF records, it’s time to consolidate them into a single record. Here’s how:

  • Determine all the servers that need to be included. This could be your own mail server, third party services like Mailchimp, or any other service that sends emails on your behalf.
  • Create a new SPF record that includes all these servers. For example:
v=spf1 include:mailgun.org include:sendgrid.net -all

This record allows both Mailgun and SendGrid to send emails for your domain. Make sure to end with -all to indicate that only the listed servers are authorized.

Step 3: Update Your DNS

Go to your DNS provider and replace the old SPF records with the new consolidated one. Make sure to delete any other SPF records to avoid confusion.

Step 4: Validate Your SPF Record

After updating your DNS, it’s crucial to validate the new SPF record. You can use the SPF generator from InboxGreen to ensure it’s correctly formatted. Just enter your details, and it will provide you with a valid SPF record.

What About DKIM and DMARC?

While fixing your SPF records, don’t forget about DKIM and DMARC. These records work in tandem with SPF to enhance your email security and deliverability. DKIM adds a digital signature to your emails, while DMARC helps you set policies for how receiving servers should handle emails that fail SPF or DKIM checks.

To set up DKIM, you’ll need to generate a DKIM key and add it to your DNS records. For DMARC, create a record like this:

v=DMARC1; p=none; rua=mailto:[email protected]

This record tells receiving servers to send reports about your email authentication results. You can use the DMARC generator to create a custom record easily.

Monitoring Your Results

After making these changes, keep an eye on your email deliverability. Use tools like InboxGreen to monitor your inbox placement rates and engagement metrics. It’s essential to ensure that your emails are landing where they should.
