Test referral rewards and welcome offers with test accounts

Testing referral programmes and welcome offers

A referral needs at least two accounts your app has never seen, and a welcome offer needs a brand-new customer every time. Testing the rules properly also means trying to break them, on your own staging site.

The accounts you need

Account	Part in the test	What it checks
Referrer	An existing customer who shares their link	The referral link or invite email, and the reward when a friend qualifies
Friend	Signs up from the link	Arrives with the referral applied and gets the friend’s offer
Second friend	Signs up from the same link	Rewards add up, or stop at the cap
Self-referral	The referrer’s own second account	Caught by your rules: no reward
New customer	Signs up with no link	Gets the welcome offer, once
Repeat claim	A customer who tries the welcome code again	Refused, with a clear message

Set them up

Create the set in one go: choose Add account, set How many, label the batch “Referrals” and tick Generate persona.
Sign up the referrer first and copy their referral link.
Sign up each friend from the link in a private window, so no session or cookie carries over.
Note on each address who referred it and what it should get, for example “Referred by k3f9 · expect £10 credit after first order”.

What to check

The link survives: the referral is still attached after email verification and after a pause before the first purchase.
Rewards land at the right moment: for both sides, only when the qualifying step happens, such as verifying or a first order.
Limits hold: caps, expiry dates and one-per-customer rules.
Abuse is refused: self-referrals and repeat claims from the same card, the same device, or the same email with a plus tag (name+2@ reaches the same inbox as name@, so your rules may want to treat it as the same person).
Take-backs: cancelling or refunding the qualifying order removes the reward, if your terms say it should.

The emails to check

The invite email if your app sends one, the friend’s welcome offer, “your friend joined”, “you’ve earned a reward” and reward-expiry reminders. A promo code in an email is picked out with a Copy button, ready for checkout, and the inbox shows the full email with every link.

Use these accounts only to test a referral programme or offer you run or are allowed to test, in development, staging or QA.

Questions

Can I use this to claim offers on other sites?

No. Creating accounts to collect sign-up bonuses or referral rewards from services you don't own is fraud, and it breaks our terms. These accounts are for testing your own programme in development, staging or QA.

Why do I need new addresses each time?

Most programmes reward first-time customers only, so an address that has already signed up can't test the new-customer path again. Every Proxy Mail QA address is new and has never received mail, like a real new user's.

What if my app blocks disposable email domains?

Then it may block ours too, which is worth knowing. On your staging site, allow mailclub.dev and enable.li so the rest of the flow can be tested, and test the blocking rule on its own.
