Why Your Emails Are Getting Ghosted (And How to Fix It)

How to improve email deliverability

The Spam Folder Boogeyman: What Triggers It?

Spam filters are like overprotective bouncers at a club. They’ll block you for:

  • Suspicious subject lines: “FREE!!!” or “Urgent $$$” = instant red flags 🚩.
  • Sloppy lists: Sending to invalid or inactive emails? Bounce rates spike, and spam filters notice.
  • Missing authentication: No SPF/DKIM/DMARC? You’re basically emailing in a trench coat and sunglasses 🕶️.

Pro Tip: Run a free email deliverability test (try HubSpot’s Email Health Tool) to diagnose issues before hitting send.

Slash Bounce Rates Like a Ninja

Email Bounce Rates

Bounce Rates 101: There are two types of bounces:

  1. Soft bounces: Temporary issues (e.g., full inboxes). Fix: Retry later.
  2. Hard bounces: Permanent errors (e.g., fake emails). Fix: Remove these addresses yesterday.

Action Steps:

  • Scrub your list monthly: Use tools like Hunter.io or HubSpot’s List Cleaning Feature to zap invalid emails.
  • Double opt-in: Make subscribers confirm their email. Fewer typos = fewer bounces.
  • Monitor your sender score: Sites like SenderScore.org give you a spam-filter “credit report.”

💡 Interactive Checklist:

☑️ Purge unengaged subscribers every 90 days.

☑️ Test emails across clients (Gmail, Outlook, Apple Mail).

☑️ Avoid attachments—use cloud links instead.

Keep Your Email List Cleaner Than a Marie Kondo Closet 🧹

Best practices for cleaning email lists and reducing bounce rates

A messy list is a one-way ticket to spam city. Here’s how to tidy up:

  • Segment like a pro: Send targeted content. Example: “Hey marketers!” vs. “Hey HR pros!”
  • Re-engagement campaigns: Send a breakup email to inactive users:

“We miss you! 👋 Click here to stay, or we’ll part ways.”

  • Avoid purchased lists: They’re the fast food of email marketing—cheap but toxic.

Quick Quiz: Is your list healthy?

  1. Have you emailed these people in the last 6 months?
  2. Do open rates stay above 15%?
  3. Are spam complaints below 0.1%?
    If you answered “no” to any, it’s spring cleaning time!

Spam Filter Hacks (Without Selling Your Soul)

  • DKIM: Adds a digital signature to prove you’re legit.
  • DMARC: Instructs servers what to do if your email fails checks.

B. Subject Lines That Don’t Scream “Spam”

  • Bad“Act NOW Before This Deal Expires!!!”
  • Good“Your Exclusive 30% Off Offer (Expires Friday)”
    Use Emails.ai’s Spam Checker to test phrases before sending.

C. Content That’s Actually Engaging

  • Do: Write like a human. Example:

“Hey [First Name], we noticed you left something in your cart 👀. Need a nudge?”
