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 `...`. * 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 `...` 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 `` 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. ## Screenshots [⌊The plugin's settings page, under Postie's menu - turn HTML block conversion and Markdown parsing on or off independently.⌉⌊The plugin's settings page, under Postie's menu - turn HTML block conversion and Markdown parsing on or off independently.⌉[ The plugin’s settings page, under Postie’s menu – turn HTML block conversion and Markdown parsing on or off independently. ## Installation 1. Install and activate Postie first. 2. Install and activate this plugin. 3. Optionally visit Postie’s settings > HTML & Markdown Blocks to toggle Markdown parsing and/or Gutenberg block conversion independently (both on by default). ## FAQ ### How do I get Markdown syntax converted? Wrap the part of the email you want parsed as Markdown in `` and `` tags, each on their own line: ``` # My Heading * A list item * Another item ``` This is deliberate, not automatic: this plugin never guesses whether some arbitrary content “looks like” Markdown – only content inside an explicit `...` block is ever parsed as Markdown. Content outside the wrapper (or the whole email, if you don’t use one) is treated as plain content. As a side benefit, content inside` ...` is also fully shielded from Postie’s own content-processing (its newline- collapsing, `---`-line signature stripping, and `#subject#` inline-subject extraction all run before this plugin ever sees the content, and could otherwise silently damage unwrapped Markdown syntax that happens to resemble one of those conventions) – using` ` sidesteps all of that automatically, with no workaround needed. ## Reviews There are no reviews for this plugin. ## Contributors & Developers “SLNWP Html and MD Blocks for Postie” is open source software.

Namespace, constants, option name (with automatic migration), settings slug, and CSS classes all updated to match; no functional changes #### 0.1.6 * New: blockquotes now convert to real core/quote blocks (with native inner blocks) instead of falling back to core/html * Change: settings page and readme FAQ now lead with the … marker as the single recommended fix for all of Postie’s own content-processing conflicts, not just the list one #### 0.1.5 * New: independent settings toggles for Markdown parsing and Gutenberg block conversion– block conversion can now be turned off entirely (previously always on) #### 0.1.4 * New: wrap Markdown content in … to shield it from Postie’s own newline-collapsing and signature/subject-marker collisions – fixes lists and headings-followed-by- lists coming through merged or corrupted #### 0.1.3 * Fix: Markdown list items with mail-client whitespace padding right after the marker were becoming indented code blocks instead of plain list text * Fix: literal backslashes in emailed content (e.g. Windows file paths) were being doubled when Postie saved the post – now preserved correctly #### 0.1.2 * Fix: Markdown was never parsed for real mail-client HTML – Thunderbird wraps each paragraph in its own < p>, which made every paragraph individually opaque to Parsedown’s raw-HTML-passthrough rule * Fix: a bare URL auto-linked by the mail client inside Markdown image/link syntax (e.g. Thunderbird’s freetext links) broke image/link recognition – now unwrapped before parsing * New: bullet and numbered lists now convert to real core/list blocks( with nested sub-list support) instead of falling back to core/html #### 0.1.1 * Fix: inline images within paragraph text now become their own core/image block instead of being embedded in the paragraph’s HTML * Fix: plain-text paragraphs and text preceding an inline image were silently dropped due to a simple_html_dom quirk (children() excludes text nodes) * Fix: Markdown detection now based on content patterns rather than which MIME part the email populated, so HTML-wrapped plain-text emails (Gmail/Outlook) no longer collapse to one block * Fix: horizontal rules (—) now become a core/separator block instead of being silently dropped #### 0.1.0 * Initial release: Markdown/HTML -> Gutenberg blocks conversion for paragraphs, headings, and images. ## Meta * Version **0.1.19** * Last updated **16 hours ago** * Active installations **Fewer than 10** * WordPress version ** 6.2 or higher ** * Tested up to **7.1** * PHP version ** 8.2 or higher ** * Tags * [blocks](https://wordpress.org/plugins/tags/blocks/)[email](https://wordpress.org/plugins/tags/email/) [gutenberg](https://wordpress.org/plugins/tags/gutenberg/)[markdown](https://wordpress.org/plugins/tags/markdown/) [postie](https://wordpress.org/plugins/tags/postie/) * [Advanced View](https://wordpress.org/plugins/slnwp-blocks-for-postie/advanced/) ## Ratings No reviews have been submitted yet.
