SLNWP Html and MD Blocks for Postie

This is an addon for the Postie plugin (email-to-post). It does nothing on its own – Postie must be installed and active.

By default, Postie saves emailed content as a flat HTML/text blob, so a post created from an email opens in the block editor as one big Classic/HTML block rather than proper paragraph/heading/image blocks – and a big blob is difficult to edit afterward.

SLNWP Html and MD Blocks for Postie converts that emailed content into real, individually-editable Gutenberg blocks before the post is saved with the ability to further format using markdown syntax within <md>...</md>.

• Rich HTML emails (Outlook/Gmail-style formatted mail) are normalized into blocks.
• Markdown syntax (#/## headings, blank-line paragraphs, **bold**, [links](url), */- lists, > quotes) wrapped in an explicit <md>...</md> block is parsed into native blocks. See the FAQ below.
• Emailed photo attachments become core/image blocks referencing the real WordPress attachment Postie already created, not bare <img> tags.
• Bullet and numbered lists become real core/list blocks (with each item as its own core/list-item, including nested sub-lists), not plain text.
• Blockquotes (>) become real core/quote blocks, with their contents as native inner blocks.
• Anything not yet natively mapped (code, tables – deferred past v1) falls back to a core/html block, so content is never silently dropped.
