Why Your Emails Aren’t Converting (And How to Fix Them in 15 Minutes)
Share this article:

You’ve written the subject line. You’ve hit send. You’ve got opens.

But where are the clicks, signups, or sales?

If your emails aren’t converting, it’s likely due to one (or more) of these fixable mistakes—and we’ll show you how to address them in 15 minutes or less.

  1. Weak CTAs (Calls-to-Action)
  2. Poor Mobile Optimization
  3. Visual Clutter
  4. Lack of Personalization
  5. Not Using Proven Layouts
  6. Fixing It All in MailGlider

Problem #1: Weak or Vague CTAs

Your CTA is the conversion engine. If it's weak, unclear, or blends into the email, clicks drop off.

Fix:

  • Use action-oriented verbs (e.g., “Start My Free Trial” vs. “Submit”)
  • Limit to 1 primary CTA per email
  • Place CTA above the fold when possible

Try this:
Use MailGlider’s “Bold CTA” template for sales and lead-gen emails.


Problem #2: Not Mobile-Optimized

Over 65% of emails are opened on mobile. If your buttons are small, text is cramped, or images overflow—you’re losing revenue.

Fix:

  • Use single-column layouts
  • Ensure CTA buttons are at least 44px high
  • Avoid tiny font sizes (<14px)

Mobile hack: Use MailGlider’s mobile preview mode to check responsiveness in real time.


Problem #3: Too Much Visual Clutter

If everything screams for attention, nothing does.

Fix:

  • Use visual hierarchy: headlines > body > CTA
  • Add padding and white space generously
  • Stick to one font family

“Whitespace isn’t empty—it’s breathing room for your message.” – Paul Boag


Problem #4: No Personalization

Generic emails feel like spam. Personalized content improves conversions by 202%, according to Instapage.

Fix:

  • Add dynamic name tags (e.g. "Hi {{first_name}}")
  • Show personalized products or categories
  • Trigger flows based on behavior (e.g., clicked last campaign)

Problem #5: Layouts That Don't Convert

If your layout isn’t guiding readers to a logical action, it’s working against you.

Fix:
Use proven conversion-first layouts like:

Layout Type Best Use Case
Hero + CTA Sales / Launch
Z-pattern Layout Product announcement
Minimal Newsletter Content + Community

MailGlider includes Z-pattern and CTA-optimized layouts ready to deploy.
