Why Emails Go to Spam in Gmail
Gmail uses powerful filters to protect users from junk and dangerous emails. But sometimes, even real and useful emails are marked as spam. Common reasons include:
- Your email server isn’t authenticated (missing SPF, DKIM, DMARC)
- Your email looks like spam (bad subject, layout, too many images or links)
- Gmail users marked your previous emails as spam
- You’re sending emails to people who didn’t sign up
- You’re sending too many emails at once from a new domain
- Your domain or IP has a bad reputation
Gmail updates its spam filter rules regularly to fight scams and phishing. That’s why it’s important to follow their guidelines.
How to Stop Emails Going to Spam in Gmail?
Here are the most effective strategies to help ensure your emails never land in Gmail’s spam folder again.
Step 1: Set Up SPF, DKIM, and DMARC
These are authentication records added to your domain’s DNS (your website’s backend settings). Gmail checks these records to know if your email is real.
- SPF tells Gmail which servers can send emails for your domain
- DKIM adds a digital signature to your emails
- DMARC tells Gmail what to do if SPF/DKIM fails (e.g., reject or quarantine the email)
Example: For your domain example.com, add DNS records like:
SPF: v=spf1 include:_spf.google.com ~all
DKIM: Generated key from your email provider
DMARC: v=DMARC1; p=none; rua=mailto:dmarc@example.com
Use tools like:
- https://mxtoolbox.com
- https://dmarcian.com/dmarc-record-wizard/
Result: Gmail sees you as a trusted sender
Step 2: Use Gmail Postmaster Tools
Gmail Postmaster Tools is a free dashboard that shows:
- Spam complaint rates
- Domain reputation (Good, Medium, Bad)
- Authentication success/failure
- Email delivery errors
Go to: https://postmaster.google.com
You must verify your domain to access data.
Why it matters: If your spam rate is high (>0.3%), Gmail will block or junk your emails.
Step 3: Grow a Clean Email List
Never buy email lists.
Instead:
- Use double opt-in (user signs up + confirms via email)
- Add clear unsubscribe links in every email
- Send welcome emails right after signup
Clean your list every 3–6 months:
- Remove invalid emails
- Remove subscribers who haven’t opened emails in 90 days
- Segment your list (active users vs. inactive)
A small, engaged list >a large inactive list
Step 4: Create Spam-Free Content
Write clear, useful, and honest emails. Avoid these red flags:
| Bad Practice | Better Practice |
|---|---|
| ALL CAPS or “!!!!” | Normal case |
| “Click Now for FREE $$$” | “Check our limited-time offer” |
| Image-only emails | Include real text and alt-tags |
Stick to:
- Text-to-image ratio: 60:40
- No more than 2–3 links per email
- Mobile-friendly layout
- Clear sender name (e.g. “Oflox India”)
Gmail rewards clean, helpful emails.
Step 5: Add One-Click Unsubscribe
Especially if you send more than 5,000 emails/day, Gmail requires:
- One-click unsubscribe (header + visible link)
- Fast removal from your list after clicking unsubscribe
Example header:
List-Unsubscribe: <mailto:unsubscribe@example.com>, <https://example.com/unsubscribe>
Step 6: Warm Up New Domains or IPs
If you just bought a new domain or started emailing from a new IP:
- Send small batches first (50–100/day)
- Gradually increase volume over 2–3 weeks
- Focus on engaged subscribers first
Why? Gmail needs to “trust” your domain slowly.
Step 7: Monitor Feedback and Bounce Rates
Use:
- Your email platform analytics (e.g., Mailchimp, Brevo)
- Bounce handling: Remove hard-bounced emails
- Gmail’s feedback loop: Available through Google
If bounce rate > 5%, fix list quality or authentication.
