Email Deliverability 101: How to Make Sure Your Emails Don’t End Up in Spam

You sent the email.
You waited for a reply.
But nothing came back.

Chances are… your message went straight to the spam folder.

In 2025, with aggressive filters and rising threats, email deliverability is more important—and more complicated—than ever.

Here’s a practical guide on how to ensure your emails get delivered, not discarded, and how PLiKhost Email Hosting with SpamExperts helps you stay out of the spam trap.


✉️ What Is Email Deliverability?

Email deliverability is the ability of your emails to reach your recipient’s inbox—not just “send successfully,” but actually land in the inbox, not junk or promotions.

It’s affected by:

  • Sender reputation

  • Email authentication (SPF, DKIM, DMARC)

  • Message content

  • Sending behavior

  • Spam filter rules

Even legitimate businesses can get filtered—especially if they’re using shared IPs or poorly configured email systems.


🛑 Why Do Legitimate Emails Go to Spam?

  • ❌ No SPF/DKIM/DMARC set

  • 🧱 Blacklisted IP address

  • ⚠️ Spammy subject lines or keywords

  • 🗂️ Lack of engagement (low open rates)

  • 📬 Too many emails sent at once (bulk)

  • 🔄 Previous user marked you as spam

Spam filters use algorithms to predict risk. If you “look” like a spammer, your email won’t make it.


✅ How to Improve Your Email Deliverability

1. Set Up Proper Email Authentication

Your domain should have:

  • SPF: Specifies which servers are allowed to send on behalf of your domain

  • DKIM: Adds a digital signature to verify authenticity

  • DMARC: Aligns SPF and DKIM and gives you reports on email abuse

📌 At PLiKhost, our support team helps you configure all three correctly.


2. Use SpamExperts Outgoing Filtering

PLiKhost includes SpamExperts Outgoing Email Filtering, which:

  • Monitors your email stream for spam-like behavior

  • Prevents spam from being sent by compromised accounts

  • Keeps your IP clean and avoids blacklisting

  • Enhances your sender reputation

🧼 It’s like a bouncer for your outbox—only good mail gets through.


3. Avoid Spam Trigger Words and Formats

Bad:

  • “FREE $$$”

  • “Act now!”

  • ALL CAPS SUBJECTS

  • Hidden text, misleading links

Good:

  • Use clear, relevant subject lines

  • Avoid overusing exclamation marks

  • Write like a real person, not a robot

📣 Be authentic. Spam filters love that.


4. Keep Your List Clean and Engaged

  • Remove invalid addresses (bounces)

  • Don’t send to users who never open

  • Use opt-in methods (never buy lists)

  • Let users unsubscribe easily

Engagement (opens, replies, clicks) tells filters: “this is a wanted message.”


5. Enable Email Archiving for Transparency

Using PLiKhost’s SpamExperts Archiving, you can:

  • Prove your email was sent

  • Retrieve exact content and headers

  • Investigate delivery issues

Audit logs = accountability.


6. Monitor Blacklists and Feedback Loops

Use tools like:

Know your sender score and fix issues fast.
