How to Add a Logo to Your Email Signature

Add your company logo to every email. Step-by-step guide with best practices for size, format, and placement.

What is an email signature logo?

A logo in your email signature reinforces brand recognition with every message you send. It turns every email into a branding touchpoint — recipients see your company identity dozens of times per week, building familiarity and trust without any extra effort on your part.

How to add a logo to your email signature

1

Prepare your logo

Export your logo as a PNG with transparent background or SVG. Keep the file under 200KB and host it on a public HTTPS URL (e.g., your website, Cloudinary, or an image CDN).

2

Open BrandFooter generator

Go to BrandFooter's free email signature generator and choose a template that includes a logo placement area.

3

Paste your logo URL

Enter your hosted logo URL in the logo field. The live preview will show exactly how your logo appears in the signature. Adjust sizing if needed.

4

Copy HTML and paste into your email client

Click 'Copy HTML' to copy your complete signature. Then paste it into your email client's signature settings (Gmail, Outlook, Apple Mail, etc.).

Why use a logo

Key benefits of adding a logo to your email signature.

Brand recognition

Every email you send reinforces your brand. Recipients see your logo dozens of times, building familiarity and recall without any extra effort.

Professional appearance

A logo elevates your email from a plain text message to a polished, professional communication. It signals that you and your company take presentation seriously.

Trust signal

Emails with branded signatures are perceived as more trustworthy. A visible company logo helps recipients verify that the email is legitimate.

Marketing at scale

The average employee sends 40+ emails per day. That's 40+ brand impressions daily, per person — all from a simple logo in your signature.

Tips for a logo

Best practices to get the most out of this feature.

Keep your logo under 200KB

Large image files slow down email loading and may be blocked by some email clients. Optimize your logo file to under 200KB for the best experience.

Use PNG with transparency or SVG

PNG with a transparent background works across all email clients. SVG offers sharper rendering but has limited support in Outlook desktop.

Host on an HTTPS CDN

Your logo must be accessible via a public HTTPS URL. Use a CDN like Cloudinary, your website's media server, or BrandFooter's image hosting for reliable delivery.

Always add alt text

Some email clients block images by default. Alt text ensures recipients see your company name even when images aren't loaded.

Frequently asked questions

Common questions about a logo in email signatures.

What size should a logo be in an email signature?+

Aim for 100-250px wide and 50-100px tall. This keeps the logo visible without overwhelming the signature. The file size should be under 200KB for fast loading across all email clients and devices.

What format is best for email signature logos?+

PNG with a transparent background is the safest choice — it works across all major email clients including Outlook, Gmail, and Apple Mail. JPEG works too but doesn't support transparency. SVG offers the best quality but has limited support in Outlook desktop.

Can I use SVG for my email signature logo?+

SVG works well in Gmail and Apple Mail, but Outlook desktop (which uses the Word rendering engine) doesn't support SVG images. For maximum compatibility across all clients, PNG is the recommended format.

Why isn't my logo showing in my email signature?+

The most common causes are: the image URL is not publicly accessible, the URL uses HTTP instead of HTTPS, the image file is too large, or the recipient's email client blocks external images by default. Verify your URL works in an incognito browser window.

Do I need to host the image for my email signature logo?+

Yes. Email clients don't support embedded or local file images reliably. Your logo must be hosted on a publicly accessible HTTPS URL so email clients can download and display it for every recipient.

Can I use my logo in a Gmail email signature?+

Yes. Gmail fully supports images in signatures via HTTPS URLs. Create your signature with BrandFooter, copy the HTML, and paste it into Gmail's signature settings under Settings > See all settings > General > Signature.
