🖼️ Personalize Your Sidebar
You can add a background picture behind the left sidebar in Mailbird Next. Choose an included picture, upload your own, or use the AI image generator.
This changes the sidebar background, not your account avatars or the backgrounds inside your emails.
⚙️ Choose a Sidebar Picture
- Open Settings.
- Select Sidebar.
- Find Sidebar background.
- Click an included picture to apply it.
Your selection is saved automatically. You can also right-click an empty area of the sidebar and choose Customize sidebar to open its settings.
📷 Add Your Own Picture
- Go to Settings > Sidebar > Sidebar background.
- Click Add custom image.
- Select a JPG, JPEG, or PNG image from your computer.
The imported image is applied automatically and appears among your available backgrounds.
💡 Tip: Pictures are scaled and cropped to fill the sidebar. Try an image with its main subject near the center, and check how it looks with your preferred sidebar width.
✨ Create an AI-Generated Picture
- Click Add AI-generated image.
- Describe the picture you want in Describe your background image.
- Optionally choose a Content type, Color and tone, and Image lightness.
- Click Generate.
- Select a result to preview it, then click Apply selected image.
⚠️ Note: AI image generation is subject to usage limits. Follow any allowance or limit message shown in Mailbird Next. Selecting a generated result previews it; click Apply selected image to keep it.
🔎 Keep Sidebar Text Easy to Read
Enable Increase menu text readability to add a contrasting overlay over the picture. This helps sidebar labels stand out. The option is available when a background picture is selected.
🔄 Remove or Delete a Picture
- Return to the theme background: select the first tile, with the crossed-circle symbol. Its tooltip reads No image: use the theme background. Your custom images remain available.
- Delete a custom or generated image: hover over its thumbnail, choose Delete image, and confirm. If it was your active background, the sidebar returns to the theme background.
Picture which are included by default in Mailbird Next cannot be deleted.
