Imagine crafting the perfect email campaign—only for it to land in the spam folder instead of your recipient’s inbox. Frustrating, right?
If your emails keep going to spam, it means:
❌ Your audience isn’t seeing your emails.
❌ You’re losing leads, sales, and engagement.
❌ Your sender reputation is being damaged, making future emails even less likely to reach inboxes.
The good news? By following a few best practices, you can improve your email deliverability and keep your emails out of the spam folder.
Why Do Emails Go to Spam?
Spam filters analyze hundreds of factors to decide if an email is legitimate or spam. Common reasons your emails might be flagged:
📌 Spammy words in the subject line (e.g., “FREE,” “LIMITED OFFER,” “WIN NOW”)
📌 Your domain/email isn’t authenticated (DKIM, SPF, DMARC missing)
📌 Low sender reputation (sending too many emails too fast)
📌 Lack of engagement (recipients marking your emails as spam)
📌 Too many links or images in the email
📌 Purchased or low-quality email lists
Let’s fix these problems so your emails actually reach inboxes!
1️⃣ Use a Professional Business Email Address
🚫 Bad: yourbusiness@gmail.com
✅ Good: contact@yourbusiness.com
Free email providers (Gmail, Yahoo, Outlook) often trigger spam filters when sending bulk emails. Using a business email with your own domain improves trust and deliverability.

2️⃣ Authenticate Your Email (SPF, DKIM, DMARC)
📌 What it is: Email authentication proves to email providers that you’re a legitimate sender.
✔️ SPF (Sender Policy Framework) – Prevents email spoofing & forgery.
✔️ DKIM (DomainKeys Identified Mail) – Verifies email authenticity.
✔️ DMARC (Domain-based Message Authentication) – Helps prevent phishing & fraud.
💡 How to Set It Up:
- Log into your domain provider (e.g., Define Hosting, GoDaddy, Cloudflare).
- Add SPF, DKIM, and DMARC records in your DNS settings.
- Use a tool like MXToolBox to check your email authentication status.
🚀 Without email authentication, your emails are more likely to be rejected or marked as spam!
3️⃣ Avoid Spam Trigger Words in Subject Lines
🚨 Certain words & phrases can trigger spam filters.
🔹 Common Spam Words to Avoid:
❌ “FREE”
❌ “Make money fast”
❌ “Win big now”
❌ “Act now”
❌ “Urgent offer”
💡 Instead, use clear and engaging subject lines:
✔️ “Exclusive Offer for You, [First Name]”
✔️ “Get 10% Off – Limited Time”
✔️ “Your Free Guide is Ready”
🚀 Keep subject lines simple, avoid ALL CAPS, and don’t overuse exclamation marks!!!
4️⃣ Keep Your Email List Clean & Engaged
📌 Why? If too many people ignore, delete, or mark your emails as spam, your email reputation suffers.
✔️ Remove inactive subscribers (people who haven’t engaged in 6+ months).
✔️ Use double opt-in (requires users to confirm their subscription).
✔️ Segment your email list (send emails only to interested users).
✔️ Encourage engagement (ask subscribers to reply to your email).
💡 Pro Tip: The higher your engagement, the better your deliverability.
🚀 Use tools like Mailchimp, ActiveCampaign, or ConvertKit to manage your email list efficiently!
5️⃣ Avoid Too Many Links & Images
📌 Spam filters flag emails with excessive links & images.
🚫 Bad Email Format:
❌ A single image with no text
❌ Too many hyperlinks
❌ Overusing emojis
✅ Best Email Practices:
✔️ Maintain a 60/40 text-to-image ratio.
✔️ Use 1-3 links max in your email.
✔️ Keep your email well-formatted & readable.
🚀 Spam filters love text-heavy, well-structured emails!
6️⃣ Include a Clear Unsubscribe Option
📌 Why? If people can’t unsubscribe easily, they mark your email as spam.
✔️ Always include an unsubscribe link at the bottom of your email.
✔️ Make it easy to opt out (no hidden unsubscribe process).
✔️ Avoid misleading tactics (like making the unsubscribe text too small).
🚀 A clean unsubscribe process improves sender reputation and prevents spam complaints.
7️⃣ Warm Up Your Email Sending Reputation
📌 What it is: If you send too many emails too fast, spam filters might block you.
Best Practices for Sending Emails:
✔️ Start with small batches (100-200 emails per day).
✔️ Gradually increase volume over time (if sending bulk emails).
✔️ Maintain a consistent sending schedule.
✔️ Monitor bounce rates (too many bounces hurt reputation).
💡 Use email warm-up services like Mailwarm to build a good sender reputation.
🚀 The more trusted your email address, the less likely your emails will go to spam!
8️⃣ Test Your Emails Before Sending
📌 Why? Testing your email ensures it passes spam filters and reaches inboxes.
✔️ Use email testing tools like:
- Mail-Tester (https://www.mail-tester.com)
- GlockApps Spam Test
- Litmus Email Testing
🚀 These tools show your spam score & recommend improvements.
9️⃣ Use a Reputable Email Marketing Service
📌 Why? Poor email servers = more emails going to spam.
Best Email Marketing Platforms for Deliverability:
✔️ Mailchimp – User-friendly, great for beginners.
✔️ ActiveCampaign – Advanced automation & segmentation.
✔️ ConvertKit – Best for creators & bloggers.
✔️ Klaviyo – Great for eCommerce businesses.
💡 Pro Tip: If you send marketing emails, avoid Gmail, Yahoo, or Outlook—use a dedicated email service!
🚀 Email marketing services follow best practices to improve email deliverability.
