If customers say your emails are landing in their junk folder — or worse, you don’t even know it’s happening because nobody tells you — this is one of the most common Google Workspace problems I get asked about. It’s also one of the most misunderstood: most people’s first instinct is to blame Gmail, but the real cause is almost always something in your own domain’s configuration.
Here’s what’s usually behind it, what not to waste time on, and how to actually confirm the cause instead of guessing.
Why This Happens
Spam filtering — Gmail’s included — is mostly a trust check. It’s asking: is this domain who it claims to be, and does it behave the way a legitimate business does? When the answer isn’t clearly yes, your email gets treated as suspicious by default.
The most common reasons I find:
SPF is missing, wrong, or broken.
SPF lists which servers are allowed to send email for your domain. If it’s missing, misconfigured, or has too many lookups, authentication can fail silently — with no bounce message to warn you.
DKIM isn’t set up, or was added in the wrong place.
DKIM signs your outgoing mail so receiving servers can verify it’s genuinely from you. A common mistake: adding the DKIM record to your domain registrar when your DNS is actually managed somewhere else — it looks correct in a basic check, but fails on real mail servers.
DMARC exists but does nothing.
Most businesses either have no DMARC record, or leave it at p=none — which only logs failures instead of protecting you.
Your domain or IP has a reputation problem.
A past spam incident, a compromised account, or a badly configured bulk-sending tool can get a domain flagged even after the DNS records are fixed.
The domain is new and hasn’t built any sending reputation yet.
If you recently set up or migrated to Google Workspace, Gmail and other providers simply haven’t seen enough legitimate mail from your domain to trust it yet — this is different from a broken configuration, and it resolves differently.
Authentication passes, but something else doesn’t.
Occasionally SPF and DKIM are both correct, and email still lands in spam because of sending patterns, content, or low recipient engagement. This is less common, but worth knowing about before you assume DNS is the whole story.
One pattern worth knowing about: sometimes a setup or migration works fine for the first few days, and spam problems only show up a week or two later. That’s not a new issue appearing out of nowhere — it usually means something (DKIM signing, most often) was never actually enabled correctly in the first place, and it just took a while to affect enough mail for anyone to notice.
What Not to Waste Time On
✕Don’t just resend or “mark as not spam” and move on. It might land correctly once, but the underlying cause is still there for the next email.
✕Don’t guess your way through DMARC changes. Tightening DMARC before SPF and DKIM are properly aligned can cause more legitimate email to bounce, not less.
✕Don’t assume it’s “just Gmail being Gmail.” In almost every case I’ve looked into, there’s a specific, findable, fixable reason — it’s rarely random.
How to Actually Confirm What’s Wrong
Rather than changing settings and hoping, the right order is:
Step 1Check your current SPF, DKIM, and DMARC records
— not just whether they exist, but whether they’re correctly formatted and aligned with how you actually send mail.
Step 2Check your domain and sending IP against major blacklists
and if you have it set up, check Google Postmaster Tools for a domain reputation and spam-rate view straight from Google.
Step 3Send a test email and inspect the authentication headers
— this tells you definitively whether SPF/DKIM/DMARC are passing, rather than guessing from a generic online checker.
Step 4Only then decide what to change
based on what’s actually failing.
This is exactly the audit-and-fix process I run for clients — it’s a fixed-price, same-day service rather than an open-ended investigation, because the diagnostic steps above usually surface the cause quickly once someone knows what to look for.
A Real Example
One client had been fighting spam-folder problems for over a week, and Google Support had already told them the issue was “on the recipient’s end.” It wasn’t. The actual cause: DKIM sitting in the wrong DNS zone, SPF exceeding the lookup limit, and DMARC stuck at p=none. All three were fixed and verified in about 40 minutes — test emails were landing in the inbox within half an hour of the DNS change propagating.
Get This Diagnosed and Fixed
I run a full SPF/DKIM/DMARC audit, blacklist check, and fix as a fixed-price service — most single-domain cases are resolved the same day.

FAQ
I checked SPF and DKIM myself and they look fine — why is email still going to spam?
Authentication passing on a basic checker isn’t the same as authentication working correctly on real mail servers — alignment and DNS zone placement matter. Occasionally the cause is reputation or sending pattern, not authentication at all. This is exactly why a full audit checks more than just “does the record exist.”
Will fixing DMARC block legitimate emails?
It can, if tightened before SPF and DKIM are properly aligned. The safe order is: confirm SPF and DKIM are correct first, then adjust DMARC gradually — not the other way around.
Is this a Google Workspace problem, or a DNS problem?
Almost always DNS — SPF, DKIM, and DMARC all live in your domain’s DNS records, not inside Google Workspace itself. Google Workspace is just where you’re noticing the symptom.
We just set up a brand-new domain — is that why emails are going to spam?
It can be. A new domain hasn’t built any sending history yet, so mail providers are naturally more cautious with it at first. This is different from a broken configuration, and it’s worth confirming which situation you’re actually in before assuming something’s misconfigured.
How fast can this actually be fixed?
Once the real cause is identified, most single-domain fixes are same-day. The DNS change itself is usually quick; the time that matters is propagation and verifying it actually landed in the inbox, not just passed a check.
