Adding images
Upload, manage, and insert images into your emails.
There are several ways to get an image into an email — pick whichever fits your flow. Every image you add is hosted by Sendra automatically and stored in your media library.
Inserting images in the editor
| How | What happens |
|---|---|
Slash command — type /image | Opens a file picker; the uploaded image is inserted as a block |
| Toolbar → Insert image | Opens the media picker to upload a new image or reuse an existing one |
| Drag and drop | Drop an image file straight onto the editor canvas |
| Paste | Paste an image from your clipboard directly into the editor |
Reusing an existing image
When the media picker is open, search by filename and select any image you've uploaded before. This is the fastest way to reuse a logo or banner across campaigns without re-uploading.
Images outside the editor
- Brand logo — upload it in Settings → Brand. It appears in email headers and the preference center via the
{logoUrl}token. - HTML mode — when editing raw HTML, reference any image by URL in a standard
<img src="…">. Copy a hosted URL from the media library with Copy URL, or point at an externally hosted image. - Reusable components — images saved inside a component come along whenever you insert it.
Supported formats and limits
| Formats | JPEG, PNG, GIF, WebP, AVIF |
| Max file size | 5 MB per image |
Images are hosted for you and served from a stable public URL — there's nothing to configure. Usage counts against your plan's storage quota; see Image storage & quotas.
Best practices
- Optimize before uploading — compress images to keep email file sizes small. Large emails are more likely to be clipped by Gmail (which truncates emails over ~102 KB).
- Use descriptive alt text — some email clients block images by default. Alt text ensures your message still makes sense.
- Avoid text in images — screen readers can't read text baked into images, and it doesn't scale well on mobile.
- Width matters — email content areas are typically 600px wide. Images wider than this are scaled down, which can cause blurriness. Upload at the intended display size, or 2× for retina.
