Why is my Outlook emails going to spam?
The Hidden Cost: What Junk Folder Placement Says About Your Brand
Let’s step back and look at this from your customer’s perspective.
They sign up for your product. They're waiting for a confirmation or a password reset. Nothing shows up. They refresh their inbox. Still nothing.
Eventually, they go digging through their spam folder. And there it is - next to a phishing email, a crypto pump scam, and some fake UPS notification.
Even if they find it (and most won’t), the damage is already done.
Landing in spam doesn’t just lower open rates. It brands you unintentionally as untrustworthy.
It tells your customer, “This sender doesn’t seem safe.”
It makes your product feel unfinished, low quality, and risky to use.
And worse, Outlook users may start ignoring your future emails altogether, even if they do reach the inbox.
Most product teams miss this point. They focus on deliverability as a technical metric “did the email get sent?” - but your customers experience it as a trust signal.
Microsoft filters are trained to associate you with bad senders if you share any traits - IPs, domains, headers with actual spammers.
It’s guilt by association. That means if your ESP uses shared IPs, shared bounce domains, or signs your email with their DKIM key, you're in the same bucket as whoever just blasted 100,000 fake invoices an hour ago.
That’s why Lemon Email takes ownership of everything: the infrastructure, the headers, the IPs, the authentication. Because any element you don’t control can quietly poison your brand reputation.
Deliverability = Brand Integrity
When your messages land in Outlook spam, your brand is paying for it - whether you see it or not. You're losing conversion, eroding trust, and signaling “we don’t have it together.”
Lemon Email helps you avoid that entirely by engineering trust at the infrastructure level.
It's not really about vanity metrics. It’s about the message your email sends before anyone even reads it.
If you're building something people rely on - an app, a marketplace, a product or a service.
They need to trust you from the first touch.
Lemon Email gets your messages out of the junk folder and into the inbox, where they belong.
It's not just about deliverability anymore, it's about protecting your brand.
