Hundreds of real test inboxes, in seconds.
QA and dev teams need a unique, working email for every signup they test. Spin up throwaway-but-real mailboxes in 3 seconds, read every confirmation in one inbox, and automate it over the API — without burning your work domain.
Testing signup flows shouldn’t cost you your domain
Validating a registration flow, an onboarding sequence, or a referral loop means creating dozens of accounts — each needing a real address that can receive the confirmation. The usual options all bite back.
Burning your work domain
Pointing 50 test signups at you+test@company.com floods your own inbox and trains corporate spam filters to distrust your domain. The deliverability damage outlasts the test.
Fake addresses don’t receive
Made-up addresses bounce, and disposable 10-minute mail expires before your async confirmation or day-2 onboarding email ever arrives. You can’t test what you can’t receive.
Manual juggling doesn’t scale
Creating Gmail accounts by hand hits phone checks and 7-day cooldowns. By account 20 you’ve spent a day and have nowhere clean to read the results.
How QMailing fits a test workflow
Create as many real mailboxes as your plan allows — each a working address under @qmailing.com (or your own domain from Plus). Every test email lands in one unified inbox, tagged by mailbox, and the same actions are available over the REST API + webhooks on every paid plan.
Spin up test addresses
Need 30 addresses for a batch of signups? Create them in seconds — no phone, no verification email, no cooldown. Each is a real mailbox that actually receives.
Read every confirmation in one place
Confirmation links, OTPs, day-2 drip emails — all arrive in one unified inbox, tagged by which test mailbox they hit. No profile-switching to check 30 accounts.
Automate it over the API
On any paid plan you get API tokens + webhooks: create mailboxes, fetch messages, and get a webhook when mail arrives — so your CI or end-to-end suite can drive the whole signup-and-confirm loop.
Who tests this way
Anyone who needs many real inboxes that receive — without polluting production.
QA: signup, OTP & onboarding flows
Validate registration, email verification, password reset and drip sequences against real addresses that actually receive the mail — not stubs that hide bugs.
Dev sandboxes & previews
Give each preview environment or feature branch its own mailbox so test data never crosses streams and confirmations are easy to find.
Demo & seed accounts
Seed a staging app with dozens of believable users, each with a real inbox you can open to grab a magic link or invitation.
Test inboxes vs the usual options
Each shortcut fails testing in its own way. The honest cut:
| Volume | Really receives | Automatable | |
|---|---|---|---|
| QMailing | Up to 400 mailboxes | Real, permanent mailboxes | REST API + webhooks (paid plans) |
| Disposable / 10-min mail | Unlimited but ephemeral | Expires before async mail arrives | Rarely a stable API |
| Your work domain (+tags) | One inbox, no isolation | Yes, but floods your inbox | Hurts your domain reputation |
| Multiple Gmail accounts | Phone + 7-day cooldown each | Yes | Against ToS to automate |
Stop burning your domain on test signups
The Free plan gives you 5 mailboxes to try it. Paid plans add API access + webhooks and up to 400 mailboxes from $3/mo.
