SPF, DKIM, and DMARC Authentication

SPF, DKIM, and DMARC Authentication are essential email authentication protocols that help verify the identity of the sender and prevent fraudulent use of your domain. This feature is critical for maintaining your email deliverability and protecting your brand reputation. Beginning in February 2024, major mailbox providers like Gmail and Yahoo will require these authentication methods to ensure legitimate communication, making it vital for ActiveCampaign users to implement them thoroughly.

Introduction

Email authentication is the process of verifying that the emails sent from your domain are legitimate and not from unauthorized users or spammers. Implementing SPF (Sender Policy Framework), DKIM (DomainKeys Identified Mail), and DMARC (Domain-based Message Authentication, Reporting & Conformance) is crucial, especially as email providers enhance their security measures against phishing and spoofing. Without proper authentication, your emails may end up in spam folders or fail to be delivered altogether.

These protocols work together: - SPF specifies which servers can send emails on behalf of your domain. - DKIM adds a cryptographic signature to your emails, verifying legitimate senders. - DMARC establishes a policy for handling emails that fail SPF or DKIM checks.

By setting up these authentication methods, you improve your email deliverability, enhance security, and bolster your brand's reputation.

How to Access this Feature

To begin the authentication process, log into your ActiveCampaign account and navigate to the Settings section. From there, go to the Email subsection. You will find the options for configuring SPF, DKIM, and DMARC under the Sending Domain settings.

Step-by-Step Instructions

The following steps will guide you through the process of setting up SPF, DKIM, and DMARC authentication:

1. **Access the Sending Domain Configuration**:

  - Go to Settings > Email > Sending Domains.

2. **Add a Sending Domain**:

  - Click on the Add Domain button, where you can enter the domain you intend to authenticate.

3. **Choose Authentication Method**:

  - You will be presented with two options:
    - Configure Domain: ActiveCampaign will automatically set up SPF, DKIM, and DMARC for you.
    - Set up Manually: Follow the guided steps to manually configure the records.

4. **Setting Up DNS Records**:

  If you chose the manual setup, you will be guided to configure specific DNS records in your domain's DNS management interface:
  - **SPF**: ActiveCampaign utilizes a Mailserver Domain setup, meaning you will point to them via a CNAME record.
  - **DKIM**: ActiveCampaign will provide a public key that you need to insert into your DNS settings.
  - **DMARC**: You will set up a basic DMARC record that you'll need to manage further for strict policies.

5. **Verify Setup**:

  - Once you complete your DNS configurations, return to ActiveCampaign to verify that SPF, DKIM, and DMARC records are set up correctly.

Configuration Options and Settings

- The authentication involves multiple DNS records:

 - **SPF Record**: It is a TXT record indicating which servers can send email on behalf of your domain. If you have an existing SPF record, you will modify it rather than creating a new one.
 - **DKIM Record**: This is a unique cryptographic signature added to the header of your emails, which you verify through a public key in your DNS.
 - **DMARC Policy**: 
   - **None**: No specific action taken; useful for monitoring.
   - **Quarantine**: Emails are moved to spam if checks fail.
   - **Reject**: Emails are bounced if they don’t pass the authentication checks.

At all times, ensure your configurations align with best practices for email authentication.

Best Practices and Tips

1. **Use a Valid and Established Domain**: Your domain must be more than 30 days old and point to an actual website, not a blank or parked page. 2. **Update Regularly**: Keep your DNS records updated to reflect any changes in mail servers. 3. **Monitor Deliverability**: Use the reporting features to monitor the success of your email campaigns. 4. **Consistently Clean Your List**: Regularly perform list hygiene to maintain the quality of your email list. 5. **Educate Yourself on Authentication**: Regularly refer to guides about SPF, DKIM, and DMARC to understand updates and best practices.

Troubleshooting

If you encounter issues with email delivery, consider the following troubleshooting tips: - Ensure your DNS records are properly configured according to ActiveCampaign's specifications. - Use online tools to check the status of your SPF, DKIM, and DMARC records. - Check for any conflicting SPF records if you have multiple records or services sending from your domain.

Should you continue to face problems, consult with your DNS provider or reach out to ActiveCampaign's support for assistance.

FAQ

1. **Why do I need to set up SPF, DKIM, and DMARC?**

  To ensure your emails are delivered without interference and to protect your domain from phishing and spoofing attacks.
 

2. **What happens if I do not set up these authentication methods?**

  Your emails may be marked as spam or rejected by major email providers, significantly impacting deliverability.

3. **Can I use a new domain for sending emails?**

  Yes, but ensure to warm it up first and follow best practices for new domains.

4. **How do I verify that my authentication is working?**

  Use online validation tools for SPF, DKIM, and DMARC configurations to check their statuses.

5. **What is the impact of having multiple SPF records?**

  You should only have one SPF record; multiple records can lead to authentication failures.

6. **How can DMARC improve my email deliverability?**

  It helps enforce stricter policies against unauthorized emails, enhancing the credibility of your domain.

7. **Is BIMI related to SPF, DKIM, and DMARC?**

  Yes, BIMI requires DMARC to be set in Enforcement mode and allows you to display a brand logo in emails.

By setting up SPF, DKIM, and DMARC authentication, you protect your domain, reinforce your brand integrity, and enhance email deliverability. Make sure to regularly review these settings to maintain optimal email performance and security. ```
