Fastmail email skills: browser-driven email workflows (search, read, compose, reply) and sending-identity management via the fastmail-actions workflows.
Add one or more email addresses to a Fastmail account as selectable "From" (sending) identities by triggering the add-from-address GitHub Actions workflow in the Adam-S-Daniel/fastmail-actions repo (which does the JMAP work with the FASTMAIL_API_TOKEN repo secret). Trigger when the user wants to "add a from address", "add a sending identity", "let me send as X", "add an alias I can send from", or "register a new From address in Fastmail". Supports a dry-run (whatif) preview. For discovering which received alias addresses are worth adding, use the add-received-from-addresses skill instead.
Discover which of a Fastmail account's own alias addresses are worth being able to send from, and add them as "From" identities, by triggering the add-received-from-addresses GitHub Actions workflow in the Adam-S-Daniel/fastmail-actions repo (which does the JMAP work with the FASTMAIL_API_TOKEN repo secret). It scans every message for distinct X-Delivered-To addresses, keeps only those you actually correspond through, drops any that are already identities, and adds the rest. Trigger when the user wants to "add From addresses for aliases I actually use", "find alias addresses worth sending from", or "set up identities for the addresses that receive my mail". Supports a dry-run (whatif) preview. To add a specific known address, use the add-from-address skill instead.
Automate Fastmail email workflows via a local browser session. Use this skill ONLY when running on Adam's computer with access to his browser (e.g. via Claude desktop / Cowork mode with Claude in Chrome). Do NOT use in headless environments such as the Claude Code CLI, CI pipelines, or any context without an interactive browser available. Trigger when the user wants to: search Fastmail for emails by sender, subject, or keyword; read email threads or attachment contents (including spreadsheets); compose and send new messages; or draft and send replies. Trigger on any mention of "Fastmail", "check my email", "search my inbox", "reply to", or similar email-management requests.
