Stylesheets

Manage CSS stylesheets that are automatically inlined into email templates for maximum email client compatibility.

Why Inline CSS?​

Most email clients strip <style> tags and external stylesheets. Posta automatically converts your CSS into inline styles, ensuring consistent rendering across Gmail, Outlook, Apple Mail, and others.

Create a Stylesheet​

POST /api/v1/users/me/stylesheets
{
  "name": "brand-styles",
  "css": "h1 { color: #333; font-family: Arial, sans-serif; } .btn { background-color: #7c3aed; color: white; padding: 12px 24px; border-radius: 6px; text-decoration: none; }"
}

List Stylesheets​

GET /api/v1/users/me/stylesheets?page=1&size=20

Update a Stylesheet​

PUT /api/v1/users/me/stylesheets/{id}
{
  "name": "brand-styles-v2",
  "css": "h1 { color: #1a1a1a; } .btn { background-color: #6d28d9; }"
}

Delete a Stylesheet​

DELETE /api/v1/users/me/stylesheets/{id}
