All your email, in one place.
Connect the accounts you already have, add as many Rebound aliases as you like, and read, send and sort it all from one inbox. Free to start. Built for individuals, teams and developers.
Who Rebound is for
If you juggle more than one email address, or send email from software, it's for you.
Keep everything in one inbox
Link Gmail, Outlook or Yahoo, then add Rebound aliases for shopping, sign-ups and side projects. Junk is filtered, known threats are quarantined, and you can drop an alias any time and reclaim it within 10 days.
Shared addresses, clear owners
Create an organization, invite people, share addresses like support@, and give everyone a branded address on your own domain. Owners and managers see what they need, nobody sees more.
An API, not a project
Send signed email and in-app messages with a key scoped to just what it needs. Same addresses, same inbox, no separate mail stack to run.
How it works
Three steps, and the same for everyone.
Sign up
Use your email, Google, or just a Rebound address if you'd rather not share an outside one.
Bring your mail together
Connect existing accounts, claim Rebound aliases, or add your own domain. Each alias has its own mailbox, and you choose whether its mail stays in Rebound, is forwarded on, or both.
Send and receive from anywhere
Pick any address to send from. Mail is sorted into Primary, Promotions, Social, Updates and Junk, with a Quarantine for senders known to be hostile.
Everything in one place
Rebound aliases and connected accounts share one inbox, search and compose window.
Spam handled for you
Junk is filtered automatically, and senders reported by several people are quarantined for everyone.
Aliases you control
Forward, keep, or both. Release one and reclaim it for 10 days.
Your own domain
Set up a domain once, and your team gets addresses on it, with DNS records published for you.
For developers: email from your app in a few lines
Connect your app once and send signed, tracked email from your own domain. Your real endpoint, keys and step-by-step setup are inside your account.
// Example only. Sign in to get your app's key and setup. await rebound.send({ from: "hello@yourdomain.com", to: "friend@example.com", subject: "Hello from Rebound", text: "It works." })
Built like real email infrastructure
Careful defaults, so it behaves like mail people can trust.
Real SMTP in and out
A native inbound SMTP server with TLS, and signed outbound delivery.
DKIM, SPF and DMARC
Outbound mail is DKIM-signed. Inbound mail is checked, so spoofed senders are caught.
Encrypted at rest
Message bodies are encrypted at rest, each with its own key, on keys Rebound holds. Staff work from delivery details (sender, recipient, subject, status); opening mail itself is limited to documented legal and abuse cases, and is logged.
Safe by design
Verified senders only, per-key permissions, rate limits, and optional two-factor sign-in.
Tamper-evident audit trail
Administrative actions are written to a hash-chained log, so later edits or deletions can be detected.
Roles and scoping
Operators get only the access their role and assigned organizations allow.
Ready when you are
