Templates

The template is the whole letter. PostCraft sends the chunk HTML as is, without the site header or footer.

Chunks

Templates live in chunks named PostCraft.Name. After install there are two:

Chunk	Content
PostCraft.Blank	greeting, text, links to the web version and unsubscribe
PostCraft.Promo	the same with a button

Package upgrades do not overwrite these chunks, but for your own letters a copy is handier: Create copy and a name like Offer. PostCraft saves the chunk as PostCraft.Offer. A name may contain Latin letters, digits, dot, _ and -.

Editor

The editor follows the which_editor system setting:

which_editor	Editor
CKEditor	CKEditor
TinyMCE RTE	TinyMCE
empty	HTML field

The preview shows the letter in two widths: Phones and Desktop. Refresh preview redraws it after edits, Save template writes the chunk.

Placeholders

Placeholder	Value
	web version URL
	unsubscribe page URL

PostCraft fills them for each recipient. With click tracking on, the other letter links go through the t.php redirect.

Layout tips

• Put styles into the style attribute. Mail apps often strip <style>.
• Keep the letter within 600–640 px.
• Use full image URLs with https://.
