Markup Custom Syntax Reference

All custom blocks are written inside Notion code blocks (/code). The first line is always the block type tag in square brackets. Separate slides with a horizontal rule (---).

[splash] — Full-Color Background Slide

Full-screen colored slide for a single big idea. Great for section breaks, key takeaways, or attention-grabbers.
[splash teal]
🏠
One big idea per slide
Rules
  • Line 1: [splash color] — color is teal, green, red, or purple
  • Line 2: Emoji (displayed large above the text)
  • Line 3+: Heading text (large, bold, white)
  • Left-aligned and vertically centered
  • Background color fills the entire slide

[iMessage] — iMessage Conversation

Realistic iMessage chat UI. Great for customer conversations, testimonials, or dialogue.

  • Empty lines add spacing between message groups

[email] — Email Compose UI

iOS-style email compose screen. Great for outreach templates, communication examples, or email scripts.

General Tips

  • Each custom block goes inside a Notion code block (/code)
  • Separate slides with a horizontal rule (--- or Notion's divider)
  • Block types are case-insensitive ([iMessage], [IMESSAGE], [imessage] all work)
  • You can mix custom blocks with normal Notion content on the same slide
