How to Add an Image to Email Signature

Add images and logos to your email signature in Missive.

When you add an image to your email signature, it can sometimes appear as an attachment to recipients. To prevent this, use an HTML signature with a hosted image URL instead of embedding the image directly.

Missive supports HTML signatures that let you include images properly. When you host your image on the web and reference it with an <img> tag, the image displays inline without being attached to each email.

Why images appear as attachments

When you paste or drag an image directly into a signature, it gets embedded in the email. Some email clients display embedded images as attachments, which:

• Looks unprofessional

• Can trigger spam filters

• Increases email size

The solution: Use a hosted image

1. Upload your image to a web hosting service, your company website, or an image host like Imgur or Cloudinary

2. Copy the image URL (it should end in .png, .jpg, or similar)

3. Create an HTML signature in Missive with an <img> tag:

<img src="https://yoursite.com/signature-logo.png" alt="Company Logo" width="200">

Set up an HTML signature in Missive

1. Go to Settings > Aliases & signatures

2. Select your alias or create a new signature

3. Click HTML to switch to HTML mode

4. Add your <img> tag with the hosted image URL

5. Save your signature

The image will now display properly in your emails without appearing as an attachment.
