The Brand Kit is your newsletter’s central brand definition: a set of colors, swatches, and assets that LetterBucket can apply consistently across your letters, website, and subscription forms. Access it from Design and Publish → Brand Kit in the left sidebar.

​
Brand Colors

Your brand palette is made of 8 color roles. Each role is applied to specific elements of your newsletter when you use your brand colors:
RoleApplied to
BackgroundMain newsletter background
SurfaceContainers and poll containers
BordersDividers, table borders, box borders
AccentButtons, table headers, icon containers
Accent textButton text, table header text, icons
SectionSections, columns, poll options

Click the palette card to open the color editor, pick a color for each role, and hit Save Colors.

​
Applying your colors everywhere

When saving, a “Save styles to…” dialog lets you choose where to apply the palette in the same step:
  • Brand Kit colors — always saved.
  • Letters — your email design.
  • Website — your public site.
  • Subscription form — your embedded forms.
Your brand colors also show up as one-click options elsewhere: when previewing a Template you can apply them from the Customize tab, and the letter style editor has an Apply Brand Colors option.

​
Swatches

Save additional custom colors as swatches for quick access in color pickers while designing. The section shows how many swatches you’ve used out of your maximum, and alerts you when the limit is reached.

​
Brand Assets

Upload images you reuse often — logos, signatures, banners — as Brand Assets. They’re available from the Assets tab of the media gallery when writing posts. Like swatches, assets have a maximum count shown next to the section title.
