Create Single Masked Email Address with Fastmail

This n8n workflow automates the creation of a single masked (disposable) email address using Fastmail's JMAP API. Triggered by a simple POST webhook request, it accepts optional 'state' and 'description' parameters to customize the alias. The process retrieves an authenticated session from Fastmail, creates the masked email, extracts key details, and responds with the new address—ideal for quick, secure email generation without exposing your primary inbox.

Key steps include: (1) Webhook capture of payload; (2) HTTP request for Fastmail session token; (3) POST to JMAP endpoint for email creation; (4) Data preparation (email + description); (5) Webhook response. Requires Fastmail API credentials with HTTP Header Auth; secure your webhook if public-facing.

Benefits include enhanced privacy by avoiding spam on real emails, streamlined testing for apps/signups, and easy integration via curl or shortcuts. Saves time over manual Fastmail dashboard use, perfect for personal automation or scripting.

Use cases: Temporary signups (newsletters, trials), developer testing, privacy-focused browsing, or batch alias generation in larger workflows. Scalable for Neura Market or personal setups.
