🧠 THE BIG IDEA
94% of companies were hit by phishing attacks in 2024.
Not just banks or Fortune 500 companies with dedicated IT departments, every business with a domain and an email list. Including yours.
Here's what's actually happening.
Right now, someone could be sending emails to your customers that look exactly like they came from you. Same domain and "From" name. But a fake email with real damage.
Your customer clicks a link thinking it's a promo from your brand. They land somewhere malicious. They get taken. And when they figure out what happened, they don't blame the attacker, they blame you.
All you have to do is enforce your domain to stop these attacks for good, but less than 30% of all businesses have this setup. (Source)

THE SITUATION
🔓 Your Domain Is At Risk Right Now
Every domain has a security layer called DMARC. It tells inbox providers like Gmail and Outlook what to do when someone tries to send email pretending to be you. You can set it to monitor (watch but do nothing), quarantine (route suspicious emails to spam), or reject (block them outright).
52% of all domains have no DMARC record at all. Zero protection. Zero visibility.
Of the domains that do have DMARC set up, 71.5% are still sitting on the "monitor" setting. They can see the attack happening in real time and do nothing to stop it.
If you want to see how bad the data gets across industries, this breakdown from Open Rate Club is worth 10 minutes. The numbers are worse than most people expect.
When we run an EasyDMARC report for a new client, what comes back almost always stops them cold. Not one or two suspicious sources. Hundreds. Sometimes thousands of non-compliant or outright threatening sources, all sending email using a domain the brand owner thought was locked down.

That's not a hypothetical risk. That's an active problem on brands just like yours.
THE PROBLEM
💸 This Is Draining Your Revenue
Here's the domino most people never connect:
Scammers use your domain to send fake emails. Recipients mark them as spam or report them as phishing. Gmail, Outlook, and Yahoo see the complaints rolling in against your domain. Your sender reputation takes the hit, not the scammer's. Your legitimate Klaviyo campaigns start landing in spam. Open rates drop. Click rates drop. Revenue per send drops.
Your email channel stops performing and nobody traces it back to the source.
On the backend it compounds. Email stops converting so you lean harder on paid. CAC climbs. LTV acceleration from email slows. Your unit economics on new customers start compressing. Margin shrinks from both ends simultaneously.
Research puts the revenue impact of eroded consumer trust from domain spoofing at up to 20%. For a brand doing $5M with email driving 30% of revenue, that's $300K a year leaking out of a hole you didn't know was there.
Disney, Nike, and Coca-Cola all had their domains spoofed in a single attack campaign in 2024. Full security teams. Didn't matter.
If it can happen to them, it can happen to you.
THE FIX
🚨 Here's What Enforcement Looks Like
The mistake most brands make is jumping straight to full enforcement. They flip DMARC to reject, accidentally block their own Klaviyo sends, and tank their deliverability trying to fix their deliverability.
You have to walk before you run. Here's the sequence:
Get visibility first. Turn on DMARC monitoring so you can see every source sending email on your domain. Klaviyo. Your transactional provider. Your helpdesk platform. Any third-party tool touching your domain. You need the full picture before you touch anything.
Validate every legitimate sending source. Klaviyo needs to be authenticated. Your transactional email needs to be authenticated. Every tool sending on your behalf needs to be verified and aligned. This is the step people skip. It's also the step that breaks everything when you enforce too early.
Then enforce. Once every legitimate source is clean and confirmed, you move to reject. Anything using your domain that isn't on your approved list gets blocked. The fake emails stop. Your reputation stabilizes.
EasyDMARC makes this process readable for people who aren't living in DNS records every day. Their dashboard shows exactly who's sending on your domain, what's compliant, what's flagged, and what's an active threat. It's the first tool we open on every new client audit.
Here are some examples of poor sender scores we see:

THE TAKEAWAY
📓 The Retention Wrap-Up
Your email program lives and dies on sender reputation. And sender reputation lives and dies on what's happening across your entire domain, including the activity you never authorized.
The brands that ignore this rarely notice until open rates have been sliding for six months and nobody can explain why. By then the damage is compounding and the fix takes longer.
We handle the full process inside our 30-Day Deliverability Drill-Down. Audit. Sending source audit. Authentication validation. Safe enforcement. Reputation repair. We take clients from sender scores of 3/10 to 10/10 every month.
