Do I need a paid Cloudflare account to use this skill?

No, Cloudflare Email Routing and Email Workers are available on the Free tier, though certain usage limits apply.

Why is my Email Worker failing to parse incoming messages?

Parsing libraries like postal-mime require 'node_compat: true' to be enabled in your wrangler.jsonc file to function correctly within the Workers runtime.

How do I prevent my emails from being marked as spam?

The skill guides you through the automatic setup of MX records and SPF/DKIM authentication via the Cloudflare dashboard to ensure high deliverability.

Does this skill handle email attachments?

Yes, the skill includes patterns for using postal-mime to extract filenames, MIME types, and binary content from email attachments.

Can I send emails to unverified addresses?
