Email marketing is one of the most effective ways for businesses to connect with their audience, and consistently offers some of the highest return on investment (ROI) among marketing channels.
But it's not just about sending messages—it's about sending them the right way. The new requirements by Google and Yahoo have made it clear: businesses must authenticate their emails, make it easy for people to unsubscribe, and send content that recipients genuinely want to read.
This article zeroes in on the first pillar: authenticating your emails through DMARC, SPF, and DKIM.
Without proper email authentication, your messages could end up in spam folders, or worse, damage your entire domain's reputation by being spoofed or phished.
Implementing DMARC and its companions isn't just a suggestion; it's becoming a necessity. However, the urgency drummed up by deadlines like "June 1st" doesn't mean you should rush through the setup. A thoughtful, step-by-step approach is crucial to ensure you're not just compliant but also reaping the benefits of a great sender reputation.
In this article, you will learn:
-
The essentials of DMARC, SPF, and DKIM, and why they're critical for your email strategy.
-
A guide to gradually implementing these protocols to enhance email security, deliverability, and not just maintain, but improve your open rates and other benchmarks.
-
Tips on maintaining your sender reputation with regular monitoring and adjustments.
Let's dive into making your email marketing not only compliant with the new requirements but also even more effective and trusted by your audience.
Before You Start: Lay the Groundwork
Before diving into the technicalities of SPF, and DKIM, and DMARC, let's briefly cover what they mean. Many email list owners have heard these acronyms but might not fully understand how they work together or their importance. Think of these three as the guardians of your emails' integrity, ensuring that your messages are not only delivered but also trusted by your recipients and their email providers.
Understand the Basics
-
SPF (Sender Policy Framework) is a way to tell email providers which mail servers are allowed to send emails on behalf of your domain.
-
DKIM (DomainKeys Identified Mail) adds a digital signature to your emails. This signature helps prove that the content of your emails hasn’t been tampered with during transit.
-
DMARC (Domain-based Message Authentication, Reporting, and Conformance) is a set of rules for how recipients should treat your emails. It uses SPF and DKIM to verify that an email claiming to be from your domain truly is, and provides reports that give you valuable insights on your domain reputation.
These three work together to create a way to authenticate your email communications and help your messages reach their intended destination without being blocked or flagged as suspicious.
The Right Way to Start: Gradual Implementation
The key to successful DMARC implementation is to go slowly. Immediate, all-at-once changes can lead to delivery issues, including legitimate emails being rejected or flagged as spam. You are essentially starting from scratch with Google, Yahoo, and everyone else. A gradual approach allows you to monitor the impact and adjust as needed.
Let's use our API-MO process to Assess, Prepare, Implement, Monitor, and Optimize our way through a successful implementation.
Get Ready: Assess and Prepare
Assess Your Current Setup
Before implementing anything new, check if you have SPF and DKIM records already set up. This initial step helps you understand your starting point and what adjustments might be necessary.
Prepare: Clean Your List
An engaged email list not only improves your campaign's effectiveness but also reduces costs. Sending emails to unengaged subscribers can harm your sender reputation, a crucial factor in email deliverability.
Action:
-
Segment your list: Divide your subscribers into groups based on engagement levels. This helps with targeted campaigns and allows you to start the DMARC rollout with your most engaged audience.
-
Remove inactive subscribers who haven't engaged with your emails in the last 6-12 months. This strengthens your list hygiene and improves sender reputation.
-
Use a verification service to clean your list, especially for older or unverified lists. This will reduce bounces, which affect your sender reputation. Even if an email hasn’t bounced, the address may still be inactive or has turned into a “honeypot”, designed to catch malicious actors.
Implement SPF, DKIM, and DMARC
Now that you understand the basics and have prepared your email list, it's time to set up SPF and DKIM, followed by DMARC. This section will guide you through creating and implementing these records step by step. We recommend working with your email marketing platform and a deliverability professional to implement SPF, DKIM, and DMARC. If you're setting this up yourself, we've created a step-by-step guide to support you.
Make Sure SPF and DKIM Are Right
Verify that your SPF and DKIM records are correctly set up for all email channels, including daily communications and website forms. These records are crucial for DMARC to function correctly, as they authenticate all emails legitimately sent from your domain.
Your First DMARC Record: Start with Monitoring
Creating a DMARC record with a none policy is your first step. This policy tells email providers to report back on emails they receive from your domain without taking any action on them. It lets you gather valuable data without affecting deliverability.
Once you've established a good sending history, you can consider stricter policies like p=quarantine (send non-conforming emails to spam) or p=reject (discard non-conforming emails) to further enhance security.
It's critical that you implement DMARC reporting to monitor authentication success and identify any potential issues with your email delivery, as well as giving you insights into how malicious actors may be affecting your reputation.
Warm Up Your Domain Step by Step
Domain Warmup: Gradually increasing the volume of emails sent from your domain helps build a positive sender reputation. This process is especially important when implementing new email authentication practices, as it signals to email providers that your emails are legitimate and desired by the recipients.
A careful, gradual increase in your email volume helps establish your domain's reputation as a legitimate sender. This step is crucial for avoiding spam filters and ensuring your emails reach your audience.
Start with your most engaged subscribers
Begin sending emails to your most engaged segment, such as those who opened or clicked on your emails in the last 30 days. If you send infrequently, consider splitting your engaged segment into smaller batches over several days.
Re-introduce yourself and encourage engagement
-
Craft engaging email content that reminds subscribers who you are and why they subscribed.
-
Offer valuable content, exclusive promotions, or other incentives to encourage them to interact with your emails.
-
Ask for their help in getting your emails seen and invite them to unsubscribe if the content no longer serves them.
Monitor your email performance
Regularly review essential email deliverability metrics like spam complaints, delivery rates, and authentication results in both your email marketing platform's dashboard and Google Postmaster Tools. Review your DMARC reports for additional insights into how your emails are being handled by recipients' inboxes. These reports are crucial for identifying and resolving any issues that arise during your DMARC implementation.
Identify and address issues
Look for any significant changes or trends that might indicate potential problems with your email delivery and adjust your strategy accordingly. Lower open and click rates are normal at the beginning, but should resolve quickly.
Patience and continuous improvement
-
Building a good sender reputation takes time: Allow at least 30 days to see how DMARC impacts your deliverability and adjust your approach based on the results.
-
Continuous monitoring and adaptation are key: Regularly monitor your metrics and make data-driven adjustments to your content, sending cadence, and other aspects of your email marketing strategy.
Remember, implementing DMARC is not a one-time switch, but an ongoing process. By following these steps and remaining proactive, you can successfully navigate the DMARC transition and ensure your emails reach the right inboxes, strengthening your brand reputation and achieving your email marketing goals.
Use Google Postmaster Tools
Google Postmaster Tools provides additional visibility into your email performance on Gmail that will not appear in your marketing platform's dashboard. By monitoring your spam rate, delivery errors, and more, you can improve your email practices for better deliverability and engagement.
After Everything's Running: Monitor and Optimize
With DMARC, SPF, and DKIM in place, the work isn't over. Regular monitoring and adjustments are essential to maintain optimal email performance and security.
-
Continue to monitor your email marketing platform's dashboards and Google Postmaster Tools, along with any other third party tools you may be using.
-
Regularly review your DMARC reports: this helps you understand how your emails are being received and identify any authentication issues that need to be addressed. This ongoing process ensures that your email practices remain effective and secure.
-
Review your email authentication records and settings: changing email providers, updates in practices, or adding new platforms require adjustments to your DMARC, SPF, and DKIM records.
If you encounter deliverability problems or authentication failures, it's crucial to respond promptly. Adjusting your DMARC policy, reviewing SPF and DKIM configurations, or reaching out for expert help can resolve these issues and restore your email performance.
Thinking About Stronger Policies: The Future of Your DMARC Implementation
While starting with a "monitoring only" DMARC policy of none is recommended, consider moving to quarantine or reject policies in the future. However, such a shift should only occur after a completed domain warmup, thorough testing, and when you're confident in your email authentication practices.
Conclusion
Implementing DMARC, along with SPF and DKIM, is a critical step for any business serious about email marketing. By following a gradual, thoughtful approach, you can enhance your email security, improve deliverability, and maintain a solid sender reputation.
Remember, rushing through the process can lead to significant and long-lasting deliverability issues, but by taking it step by step, you'll set your email campaigns up for success.
If you get stuck along the way, reach out for help. Together, let's make sure that your emails not only reach your recipients' inboxes but also contribute positively to your business and marketing goals.
