Gmail kicks out about 10 million spam emails a minute. A minute. And somewhere in that mountain of trash, real business emails are getting tossed too. Yours, maybe. Mine, definitely, at some point.
The thing is, most folks running a business have no clue this is even happening. They craft a decent email, click send, and figure the rest takes care of itself. It doesn’t. Not even a little.
1. Inbox Placement Isn’t Automatic
Wanna know what nobody tells you when you sign up for a fancy email tool? Paying for the software doesn’t buy you the inbox. The mailbox providers (Gmail, Outlook, Apple, whoever) get the final say. And they’re not exactly handing out free passes.
They look at a bunch of stuff before deciding where your email goes. Your reputation as a sender. Whether you’re authenticated. How folks have reacted to your past emails. The way your content reads. They run all of that through their filters in like half a second.
And if they don’t like what they see? Spam folder. Or worse, the email just disappears. No bounce, no warning, nothing. You’d never even know.
2. Why Testing Email Deliverability Beats Watching Open Rates?
Here’s where I see business owners mess up over and over. They stare at open rates as if they’re a crystal ball. Meanwhile, they never check if the emails are actually getting through.
Open rates have always been a bit of a fib. But since Apple rolled out Mail Privacy Protection back in 2021, they’re straight-up unreliable.
Apple loads images in the background, so it counts open rate whether anyone reads the email or not. You might be grinning at a 35% open rate while half your emails rot in spam.
That’s why testing email deliverability before a big push is just smart. You fire it off to seed accounts across Gmail, Yahoo, Outlook and the major ones. Then you see, plain as day, where it landed. Inbox? Promo tab? Spam? Total ghost? You’ll have your answer.
Fix that one hole, and revenue per email can jump like crazy. Not because the writing got better. The emails just started showing up.
3. The Authentication Stuff You Can’t Skip
Look, I know. Nobody got into business to fiddle with DNS records. But if you don’t get this sorted, the rest is kind of pointless.
SPF, DKIM, DMARC. Three protocols. They vouch for you when you send an email. Basically, tell the mailbox provider, “this person is who they say they are.”
Without them set up right, you look fishy from the jump. And ever since Google and Yahoo cracked down on bulk senders in February of 2024, you can’t skate by without all three.
Whatever platform you use, they walk you through it. Mailchimp, Klaviyo and ConvertKit, they all have guides. The catch? Folks zoom through the setup, spot a green checkmark, and assume it’s all good.
Then later, they’re scratching their heads, wondering why nobody’s getting their welcome emails. If you’re not sure, get a DMARC report pulled. The data won’t lie, even if your gut is.
4. Your List Is a Gold Mine or Anchor
Let’s just be honest. Most email lists are stuffed full of garbage. People who grabbed a freebie a couple of years back and haven’t opened anything since. Former customers are long gone. Bad emails that never got fixed.
Every time you send to that mess, you’re basically telling Gmail and the rest, “yeah, look how many people don’t care about me.” That tanks your reputation. And it thanks the folks who actually do open your stuff, too.
So what’s the fix? Sunset policies. Six months of no opens, and you put them through a re-engagement flow.
Three tries, that’s it. After that, off the list. I get it, cutting subscribers feels backwards. But 5,000 people who actually want your emails will smoke 50,000 who don’t. Every. Single. Time.
Oh, and don’t buy email lists. Ever. Whatever you think you’re gaining short-term, you’re not. Promise.
5. Content Still Plays a Role
Even if your authentication is dialed in and your list is squeaky clean, your content has to behave, too. Spam filters don’t only judge who’s sending. They judge what’s being sent.
SCREAMING SUBJECT LINES. Stuff like “FREE!!!” or “ACT NOW” is jammed in everywhere. Emails that are basically one giant image. Weird shortened links from sketchy domains. Any of that can trip a filter, even if you’ve done everything else right.
That said, content matters way less than it used to. The big filters now lean on behavioral signals, not keyword spotting. Still, why hand them ammo?
Clean HTML, a sensible mix of text and images, a working unsubscribe link, your physical address in the footer (that one’s the law in the US, CAN-SPAM rules). Boring stuff. But table stakes.
6. What’s Shifted Lately!
The last couple of years, the inbox has gotten meaner, not friendlier. Apple’s privacy thing. The 2024 sender rules. Microsoft is tightening up on DMARC. It’s part of a wider cleanup of email.
And honestly, if you’re playing the game straight, that’s actually a win. The bar is higher, yeah. But once you’re over it, you’re up against fewer spammy senders fighting for the same inbox space.
Wrapping This Up
If nothing else sticks, just hold onto this: pressing send is nothing. Showing up where it matters is the whole game.
Lock down your authentication. Cut the dead weight off your list, even when it hurts. Test before you send the big ones. Stop treating open rates like the truth.
Email still pulls in around $36 for every dollar spent. Wild numbers. But you only get that if your emails actually arrive. The rest? Just static.
