The Design tab controls the look of the whole email — shared across every block.
Logo
Your workspace logo appears in the header by default. Choose a different image if you like, and set the logo width. A wide logo shows centered; a small one shows alongside your organization name.
Colors
Six colors define the palette:
- Backdrop — the page background behind the email.
- Canvas — the email card background (usually white).
- Header — the band behind your logo.
- Font — body text color (headings track this too).
- Link — links and buttons.
- Browser link — the small "View in browser" link on the backdrop.
Click any color to pick from a curated palette or type a hex code.
Image corners
Choose Rounded (soft 8px corners) or Flat (square) for every image in the email. Full-width images always stay square, edge to edge.
All of these apply live — the preview updates as you change them.
