Using Images in Emails, Email Templates, and Enhanced Letterheads

Images can be used in email, email templates, and enhanced letterheads. Read more to understand the limitations.

Available in: Lightning Experience

Available in: Essentials, Professional, Enterprise, Performance, Unlimited, and Developer editions

The maximum size for an inline image is 5 MB.
Some image extensions, such as .SVG, don’t always have full support in email clients.
You can insert .SVG images into an email composer using a URL. However, Gmail doesn’t send those images with your email.
Inline images in templates aren’t supported when creating and saving templates from the Outlook and Gmail integrations.
You can add images to an email, email template, or enhanced letterhead by clicking the Source icon and including an image reference in the HTML.
When you save an email template, any content document links (Salesforce file links) are converted to content asset links.
If an email template’s HTML contains an image:
- The <html> tag is stripped out.
- A <body> tag with no attributes is stripped out. Body tags with attributes like <body style="color: maroon;" class="whatever"> aren’t impacted.

Pasting and dragging images follows these rules:

Pasted images in email composer have a character limit of 131,072 characters. If an image’s base code exceeds that limit, the partial base code is shown in the email instead of the image.
The limit for pasted images is 1 MB in the CKEditor.
Note Beginning with Summer ’24, Service Email will no longer support the CKEditor.
When you drag or paste an image to the Lightning Editor composer and the image is 5 MB or smaller, the image is inserted as an inline image at the cursor. In all other cases, files are added to an email as attachments, including multiple image files, files greater than 5 MB, and files other than images.
