CAN I VIBECODE

Newton Mail?

KINDAYou can build the valuable core, but the established product has meaningful operational complexity. Pick one narrow promise for v1.

BUILD FIRST

One specific customer type and one primary use case
A vertical slice that completes the main job without manual workarounds
Visible limits, review steps, and a fallback when an external dependency fails

LEAVE FOR LATER

Broad third-party integrations
High-scale collaboration, syncing, and permissions
Automation that can cause harm without human review

RESEARCHED BUILD PROMPT

Give this to your coding agent.

Build a focused multi-account email workspace using fixture mailboxes. Do not copy Newton Mail's brand, proprietary assets, name, logo, UI, or copy. Provide a unified inbox, conversation view, search operators, compose/reply, drafts, snooze, send-later queue, templates, labels, and simple inbox rules. Add a mock IMAP/SMTP adapter with sync status, offline cache, retry/error states, and an optional read-receipt event that is clearly disclosed. Keep credentials server-side and include delete/export/retention controls. Out of scope: real provider delivery guarantees, broad app integrations, calendar parity, team collaboration, AI autonomy, and email surveillance claims. Include a README with adapter setup, sync semantics, privacy, tests, and limitations.
