How to Fix Broken Email Images: Complete Checklist

You've designed the perfect email. The copy is tight. The design is beautiful. You're ready to send.

But will your images actually load?

This checklist takes 3 minutes and will save you from the nightmare of broken images in Outlook.

Step 1 — Check Your Format

This is the most important step. Your image format determines everything.

• PNG: Works in Outlook. Works in Gmail. Works everywhere.

• JPEG: Works in Outlook. Works in Gmail. No transparency.

• SVG: Breaks in Outlook. Gmail only via <img src>. Unreliable.

The Rule: If you're using SVG in email, convert it to PNG before you send.

Step 2 — Check Your Resolution

Retina displays are everywhere. iPhones, MacBooks, high-end Android devices. If your image isn't 2x resolution, it will look blurry.

The Rule: Always export at 2x resolution. If your email image is 600px wide, your source image should be 1200px wide.

Step 3 — Check Your File Size

Large images take forever to load. Subscribers on mobile devices will abandon your email before your images appear.

The Rule: Keep images under 1MB. Under 500KB is better. Under 200KB is ideal.

Step 4 — Convert If Needed

If you're using SVG, convert to PNG. Here's how:

1. Go to CrushSVG

2. Upload your SVG file

3. Choose 2x resolution

4. Download your PNG

5. Replace the SVG in your email

Step 5 — Test Before Sending

Never trust that your images will work. Always test.

Send test emails to:

• Outlook (Windows version — this is the most important)

• Gmail (web and mobile)

• Apple Mail (macOS and iOS)

• Yahoo Mail

If your images load in all of these, you're good to go.

Step 6 — Add Alt Text

Even if everything is perfect, some subscribers will have images disabled by default. Make sure they know what they're missing.

The Rule: Every image needs descriptive alt text. “Company Logo” isn't enough. Use “Acme Corp Logo — we help businesses grow.”
