You're checking your dashboard. Your open rate looks solid — 25%. You're planning your next campaign, maybe running a discount push to move inventory. Everything feels fine.
Except it isn't.
What if I told you that your open rate might be measuring success after your emails have already been filtered? Your 25% open rate might actually represent a much smaller percentage of your actual list — and you have no idea.
Email deliverability is the foundation your entire strategy sits on. No inbox placement means no opens, no clicks, no revenue. And most DTC founders don't discover the problem until they've already left money on the table — or worse, burned their sender reputation so badly that recovery takes months instead of days.
This is your step-by-step system. Work it, and you'll know exactly where you stand, what's broken, and how to fix it before your next campaign goes out.
Let me hit you with something uncomfortable: if you haven't checked your actual inbox placement in the last 90 days, you don't know your real numbers.

Most email marketing training obsesses over open rates and click-through rates. These are downstream metrics. They tell you what happened after your email landed somewhere — not whether it landed in the inbox at all. You're looking at a 25% open rate and thinking your email marketing is working. But what if only half your subscribers ever received the email? That 25% is really a much smaller percentage of your total list — and you have no idea.
Many experts recommend targeting an inbox placement rate of 85% or higher, with 98% to 99% representing the best-in-class range. Below that threshold, you're likely celebrating "good" metrics while a significant portion of your list never even sees your emails.
Every email deliverability issue traces back to one of three buckets:
Most experts agree that inbox placement rates below 70% signal serious problems requiring immediate attention. If that number isn't ringing alarm bells for your team, it should be.
The longer these email deliverability issues sit, the more revenue bleeds out. Your Shopify dashboard looks fine. Your email "strategy" keeps running. And your customers keep not seeing your emails.

That's a problem. And it's fixable — if you know where to look.
Before you fix anything, you need to know what you're dealing with. And that means looking at metrics most founders never check.
Most DTC founders obsess over open rates and click rates. Stop. Those are vanity metrics. They're telling you what happened after your email landed somewhere — not whether it landed in the inbox at all.

You're looking for three numbers:

These three metrics expose your real email inbox placement situation. If you're only tracking opens and clicks, you're measuring success after your emails have already been filtered. You're running sales reports without checking if the store's lights are on.
Strong email reputation management starts with knowing these baseline numbers — not the vanity stuff.
Many brands find that inbox placement rates below 85% are concerning, and rates below 70% represent a full-blown crisis where your sender reputation is in freefall and you need to act immediately.
If you don't know your exact inbox placement rate right now, you're already behind.
Now you know where you stand. Let's figure out why you're there.
Your sender reputation is the gatekeeper to the inbox. When inbox providers like Gmail or Microsoft decide you're sketchy, your emails don't land in the main tab — they land in spam, or nowhere at all.
If you're dealing with email deliverability issues, your sender reputation should be your first call. Most email deliverability failures trace back to this root cause.
High spam complaint rates are the fastest way to torch your reputation. When recipients hit "mark as spam," providers take notice immediately. That single action triggers a chain reaction: lower email inbox placement, more filtering, and eventually full blocks. Many brands find that once their engagement metrics start slipping, they're sitting on a leaky bucket that's hard to repair.
Rapid list growth without proper hygiene also hurts you. Buying lists or adding subscribers without verification tanks your reputation fast.
Your reputation isn't abstract — it's measurable. Check these three tools immediately:
If inbox providers have flagged you, recovery takes weeks, not days. Prevention is always cheaper than repair. Regular list hygiene — removing bounces and inactive subscribers — keeps your reputation healthy before it becomes a crisis.
Your sender reputation checks out? Good. Now let's look at whether your emails can even prove they're legitimate.
Your emails need passport stamps to reach the inbox.
Authentication is tight. Reputation is solid. But your list is rotting underneath you — and it's dragging everything down.
Your email list is rotting. Every day you send to addresses that don't exist, addresses that ignore you, and addresses that inbox providers have flagged as toxic. That rotting list is tanking your email deliverability.
Hard bounces are immediate poison. These are permanent delivery failures — the email address doesn't exist anymore. Every hard bounce signals to inbox providers that you're not managing your list. Do this enough, and you're blacklisted. Fast.
Remove hard bounces the moment they hit.
Soft bounces are different — those addresses are valid but temporarily unavailable. Quarantine these. Give them 30 to 60 days before you try again. If they hard bounce after that? Delete them.
Here's what most brands miss: inactive subscribers are dragging down your entire email reputation management strategy. When a large portion of your list hasn't opened an email in six months, your engagement metrics look like garbage. Inbox providers notice. They start routing your emails to spam because your open rates signal that nobody wants your content.
The fix is a quarterly hygiene cadence:
Maintaining email deliverability requires regular list hygiene including removing bounces and inactive subscribers. A healthy list isn't a big list. It's a responsive one.
By now you should have a cleaner list, tighter authentication, and a better reputation picture. Time to verify what's actually happening.
Your email deliverability problems won't fix themselves. And the fastest way to confirm if filtering is your actual issue? Check.
Send test emails from your brand address to yourself at Gmail, Outlook, and Yahoo. Then manually open each spam folder. If your own emails land there, your customers' emails are landing there too.
This isn't theoretical. It's your baseline diagnostic — and one you can repeat after every change you make to track your email inbox placement improvements. Many brands find their inbox placement well below the 85% target when test sends hit spam folders.
Beyond technical setup, your email content itself can trigger filters. Aggressive discount language screams spam to inbox providers. "BUY NOW," "75% OFF," "LAST CHANCE" — these phrases aren't just annoying, they're filter triggers.
Misleading subject lines baiting clicks work once, then destroy your email reputation management score. Excessive links or link shorteners? Same problem.
Review your last 10 sends for these patterns. If you find them, tone down the urgency and clean up your content before your next campaign.
Here's exactly what to do in the next two days. No fluff, no theory — just action.
Hour 1: Confirm your crisis. Pull your email deliverability dashboard right now. Most experts recommend targeting at least 85% inbox placement; below that threshold means your messages aren't reaching inboxes.
Hours 2-4: Run an authentication audit. Check your SPF, DKIM, and DMARC records. Authentication failures block your emails before they even get scored. Fix everything today.
SPF tells receiving servers which servers are allowed to send email for your domain. DKIM adds a cryptographic signature that proves your emails haven't been tampered with in transit. DMARC ties everything together, telling receivers what to do when authentication fails.
Here's the problem: misconfigured authentication records are frequently cited as major contributors to email delivery failures. One broken DNS entry, one missing include, and your carefully crafted flows start landing in spam.
They break for predictable reasons. You switched ESPs. You migrated domains. You updated your DNS and forgot to update your sending infrastructure. Incomplete or erroneous authentication records can prevent recipient mailservers from authenticating incoming emails — and when authentication fails, your email deliverability takes a direct hit.
Run a free authentication check via MXToolbox ↗ or your sending platform's built-in diagnostics. Look specifically at your SPF record length (too many includes breaks it), your DKIM signature status, and your DMARC policy.
If you recently changed ESPs, migrated domains, or updated DNS — your authentication records likely need updating. This isn't optional maintenance. Many experts recommend targeting 85% or higher inbox placement; below 70% is emergency territory.
Fix your authentication first. Everything else — your flows, your segmentation, your content — depends on your emails actually reaching the inbox.
Loyal Send specializes in email marketing strategies that drive real results. Let us show you what's possible.
Schedule a CallHours 5-8: Clean your list. Suppress all hard bounces immediately. Review your last three campaigns for spam triggers. Send test emails to verify inbox placement before sending anything else.

Set up ongoing monitoring. You need daily visibility into your deliverability metrics, complaint rates, and bounce patterns. Schedule 15 minutes every morning to check before your first send.
Your email deliverability isn't a technical problem — it's a revenue problem. Every email that lands in spam is a customer who didn't see your offer. Every unverified address on your list is dragging down your sender score. Every day you run campaigns without monitoring inbox placement is a day you're paying Zuckerberg's ad prices instead of owning your own channel.
