FlareMail is a web email client that turns Cloudflare Email Routing into a fast, private inbox — no IMAP or SMTP server to run. This guide takes you from signup to reading your first message. It takes about five minutes, and only one step happens outside the app.
1. Create your free account
FlareMail is FREE for your first domain. Additional domains are $9.99/mo via Paddle. Head to the onboarding page, create your account with the email address where you want setup updates sent, and open the app. When you add a second domain, checkout unlocks that subscription.
2. Open the web app
FlareMail runs in your browser at app.sendwithflare.com — no installer to download. Bookmark it like any other tool you use daily.
3. Sign in
Open FlareMail and sign in with the account you just created. New here in the app? Use the Create account tab; otherwise switch to Log in. Signing in generates your session token and fills it in automatically — you never copy or paste it by hand.
4. Confirm the connection
Open Settings (press ⌘ ,) and choose Connection. The Worker API URL is already pointed at your FlareMail backend, and the Session token was filled in when you signed in. A green dot and Connected means you're good to go.
5. Route your mail in
This is the one step outside the app. In your Cloudflare dashboard, add an Email Routing rule that delivers your address to the flaremail-api Worker. Full walkthrough here: Connect Cloudflare Email Routing. Once the rule is live, send yourself a test message — it'll land in FlareMail within seconds.
You're set
That's it. Your inbox loads instantly from a local cache (even offline), tracking pixels are blocked by default, and you can compose, label, and filter mail right away. Want to send to anyone, not just verified addresses? See Sending from your domain.
