Looking for an EmailFlare alternative that adds an inbox, REST API, and dashboard?
EmailFlare forwards inbound mail to a webhook; Flowmails is the full platform on top — a hosted mailbox, a REST API to read / send, dashboard, route tables, webhooks, and AI draft.
EmailFlare is a great product — it's where most teams land the first time they need transactional email that "just works." But as your stack matures, the calculus often shifts: data residency requirements, predictable cost at higher volumes, and the desire to own the whole mail surface — inbox, route table, events and outbound — behind one API instead of three vendors.
Flowmails is what you ship when those are the things you've started to care about. It connects to your domain provider over OAuth and runs one shared mail worker for every tenant, so your inbox, outbox, and route table live in one place, scoped to your domain. There is no per-email fee on top of your provider's own pricing; the platform subscription is what you see on the /price page.
EmailFlare itself is free / open source — you only pay Cloudflare's free tier (Workers + Email Routing). Flowmails' Base plan is also $0 forever with the same Cloudflare free tier underneath; Pro adds the dashboard, AI, and route tables for $9.9 / month, and Enterprise is $39.9 / month.
EmailFlare is a single Worker you deploy to your Cloudflare account and point at a webhook URL. Flowmails connects your domain provider over OAuth and provisions the shared mail worker, the storage and the route table, then ships a dashboard + REST surface on top — no webhook URL to wire, just the dashboard.
EmailFlare: developers who only need to forward inbound mail to a single endpoint and want to write the rest in their own Worker. Flowmails: teams that need an inbox, an API, webhooks, and a UI without writing all the storage code themselves.
EmailFlare exposes the inbound email as a POST to your webhook URL with the raw MIME body. Flowmails exposes a typed REST API — your code talks REST instead of parsing raw RFC 822, and the platform parses the MIME for you.

Migration
How to migrate from EmailFlare to Flowmails
Inventory what your webhook handler does today
EmailFlare's webhook hands your Worker the raw MIME body. If your handler currently parses RFC 822, stores parsed fields in your own database, and exposes a small API on top, Flowmails replaces all three layers with a managed one — your worker code collapses to a few REST calls.
Provision Flowmails on the same zone
Sign in to your provider over OAuth and pick the same zone EmailFlare was deployed on. Flowmails takes over the catch-all rule that EmailFlare wrote; your old Worker can stay deployed (unused) until you've smoke-tested Flowmails.
Swap your worker code for Flowmails REST calls
Replace the raw-MIME parsing in your Worker with `fm.messages.list()` / `fm.messages.get()` and `fm.send()` from the Flowmails SDK. The provider primitives (Email Routing, Email Sending) are the same ones EmailFlare used — Flowmails just adds the application layer on top.
