A real mailbox for
every test account.
Unlimited real inboxes for developers, QA, and agent builders — one for every signup, magic link, password reset, and campaign you test. Your own inbox stays clean. No plus-addressing, no shared catch-all.

You've been faking it for years —you+test42@gmail.com, a shared QA inbox, a catch-all nobody trusts. Every test email still lands somewhere you actually read. Infinibox gives each account its own real mailbox instead.
How it works
A real mailbox per account
Every signup gets its own address and inbox — real and deliverable, not a variation of yours. Spin up as many as you need.
Your inbox stays clean
Test mail never touches your personal or work inbox again. No plus-addressing, no forwarding rules, no shared account.
Works with anything that sends email
Magic links, one-time codes, password resets, receipts, campaign sends — if it can send email, it lands where you expect.
Use cases
Magic links & one-time codes
Sign in to as many test accounts as you want — each with its own inbox for its own codes.
Password resets
Run the full reset flow end to end without polluting the inbox you read every morning.
QA & demos
Give every test persona a believable, separate address — no plus signs giving the game away.
Marketing & campaigns
QA campaign sends, check rendering, and confirm what actually arrives before a customer sees it.
Give every test account a real inbox.
Stop plus-addressing. Keep your inbox clean. Set up in minutes.
