Email marketing isn’t rocket science. In fact, it’s that very simplicity that makes it so accessible to marketers and consumers alike. The basic building blocks—subscribers, lists, campaigns, and workflows—are easy enough to grasp for anyone with even a passing interest in digital marketing.
But every now and then, a technical term pops up that stops you in your tracks and makes you think, “Wait… what does that even mean?”
One of those head-scratching terms is DKIM/SPF Alignment. And while it might sound intimidating at first, understanding what it is (and why it matters) can make a real difference to the success of your email campaigns.
In this post, we’ll break it down in plain English and explain exactly how DKIM/SPF alignment works, why it’s essential for your email deliverability, and how emfluence can help you get it right.
DKIM/SPF Alignment in Layman’s Terms
Let’s take a trip back to the pre-digital age.
Imagine you get a letter (probably a bill) delivered to your home. The envelope shows a return address. That’s the old-school equivalent of your SPF domain.
Inside, the letter is signed by someone. That signature is like your DKIM signature.
Now look at the name at the top of the letter – the sender. That’s your “From” address in the world of email.
Now, imagine the letter claims to be from your bank. In order to trust that message, you’d want a few things to line up:
- The return address is your bank’s address (SPF alignment).
- The signature is from someone at your bank (DKIM alignment).
- And the sender’s name matches both.
That’s what alignment means: everything checks out. If the return address or signature is from somewhere else (like a scammer’s house), but the letter says it’s from your bank, something’s off. And you’d probably toss that letter in the trash.
How Alignment Works in Email Marketing
Fast forward to the digital age, and email works in much the same way.
When you send an email campaign—say, from newsletter@brand.com—it goes through several background checks before it ever reaches your subscriber’s inbox. These checks are handled by two protocols: SPF and DKIM.
Here’s what they do:
- SPF (Sender Policy Framework): Checks if the server you’re using to send the email is authorized to do so on behalf of your domain (in this case, brand.com).
- DKIM (DomainKeys Identified Mail): Verifies that the email content hasn’t been altered in transit and that it’s signed by the domain it claims to be from.
Now, here’s where alignment becomes critical.
Both SPF and DKIM need to match the “From” address that your subscribers see. If they don’t align, email providers like Gmail, Yahoo, and Outlook may treat your message as suspicious—even if it passes one or both checks.
This is where DMARC (another acronym – see below) comes into play.
What is DMARC?
DMARC stands for Domain-Based Message Authentication, Reporting & Conformance. It’s a protocol that builds on SPF and DKIM to give domain owners complete control over how their emails are authenticated and handled by receiving mail servers.
How DMARC Works
Here’s a simplified look at the DMARC process:
1. An email gets sent.
2. The receiving server checks:
- Does the email pass SPF or DKIM?
- Do the authenticated domains align with the “From” address?
3. Based on your DMARC policy, the server will:
- Allow the message through (none)
- Send it to spam (quarantine), or
- Block it entirely (reject)
4. The server sends back a report that helps you monitor who is sending emails from your domain (or pretending to).
You can think of DMARC as the bouncer at the door of your email domain’s VIP club. It checks IDs (SPF and DKIM), denies entry to anyone who doesn’t belong, and gives you a list of who tried to sneak in.
Why DKIM/SPF Alignment Matters to Your Email Marketing
Here’s the thing: poor DKIM/SPF alignment can destroy your email deliverability.
If your emails aren’t properly aligned:
- They could end up in the spam folder.
- Your domain could be flagged as suspicious or, worse, as a source of phishing attacks.
- Your reputation as a sender will take a hit and rebuilding it can be a long, painful process.
Most critically, your audience may never see your message. That means all your effort—content, design, strategy—goes to waste: no opens, no clicks, no conversions.
The Good News: emfluence Can Help
The great news is you don’t have to navigate this alone.
At emfluence, our email experts know how to configure SPF, DKIM, and DMARC to ensure your email domain is properly authenticated and aligned. We can help you:
- Set up and verify your SPF and DKIM records
- Ensure they align with your From address
- And implement a tailored DMARC policy that protects your brand without blocking legitimate messages.
Because when your emails are properly authenticated and aligned, they’re more likely to land in the inbox—not the spam folder.
Better Alignment = Better Results
When DKIM and SPF are aligned, your emails are trusted. Trusted emails get delivered. Delivered emails get opened. Opened emails drive engagement and ROI.
So, while DKIM/SPF alignment might sound like tech-speak, it’s really just a foundational piece of successful email marketing.
