Summary

This PR adds the "Copies and attachments" section back to the eight SDK pages for transactional email: Node.js, Python, Go, .NET, Rust, Ruby, Elixir, and PHP. It also adds the Node.js and Python tabs back to the "Receipt with a PDF" example, and the API page's note that the SDKs encode files to Base64.

#21932 (merged) removed this content because no SDK release sends cc, bcc, or attachments yet. The docs must say only what customers can do today. The content is the same as the content that was reviewed in #21932. This PR is a revert of commit 8196ea65f.

Note

🔵 Merge risk: low · two-way door

• Docs only: 11 pages, +235/-3. No component, navigation, or build change.
• docs(workflows): send transactional emails from Go, .NET, Rust, Ruby, Elixir and PHP #21932 is merged. Merge this PR only after each SDK releases copies and attachments. The server side is live in both regions.

Warning

Hold this PR until all eight SDK PRs are released:
posthog-js #5514, posthog-python #1172, posthog-go #408, posthog-dotnet #367, posthog-rs #326, posthog-ruby #325, posthog-elixir #239, and posthog-php #292.

Before the merge, add the "from version" of each release to its SDK's section, and check each version on its registry.

Checks

• The diff is an exact revert of 8196ea65f, so the rendered pages are the ones in the docs(workflows): send transactional emails from Go, .NET, Rust, Ruby, Elixir and PHP #21932 evidence at 2448c6004.
• No page moved, so pnpm test-redirects does not apply.

Eager-graph budgets are report-only until a baseline is established. Sizes are gzip of public/**/*.js; eager size is webpack module source bytes for the modules actually shipped in the entrypoint's initial chunks (post-tree-shake).
