Why Emails Send Slowly with Image Signatures (And How to Fix It)

Many users notice that emails take longer to send or arrive late when using a signature that contains a logo or image. This can be confusing and frustrating, especially when everything else seems to work fine.

The good news? This is a common issue, and it’s usually easy to fix.

What Is Happening?

When you add an image (like a company logo) to your email signature, your email becomes slightly “heavier.”

That image needs to be:

• Loaded
• Verified by security systems
• Scanned by spam filters

All of this can slow down delivery.

Why This Matters

A slow email can cause problems such as:

• Delayed communication
• Clients thinking emails were not sent
• Missed responses
• Poor professional impression

When Users Typically Face This Issue

You may notice delays when:

• Using logo/image signatures
• Sending emails with attachments
• Sending emails to strict corporate mail servers
• Sending from Google Workspace / Gmail

Simple Solution: Use a Text-Based Signature

Replacing an image signature with a text signature often speeds up email delivery.

Text signatures are:

✅ Faster
✅ More reliable
✅ Less likely to trigger spam filters
✅ Easier to read on all devices
