Use a permanent alias, not a disposable address. A trial needs to reach you twice: once now for the confirmation, and once later for the "your trial ends in three days" reminder — which is the message that decides whether you get charged. A throwaway address is gone by then. An alias keeps working, and you can still switch it off the moment the trial is over.
The expensive mistake
The instinct with a free trial is to give something disposable, because you don't intend to stay. That reasoning has a hole in it.
Trials convert to paid subscriptions automatically. The warning arrives days before the charge, at the address you signed up with. If that address expired the same afternoon you created it, you don't see the warning, and the first you know is the card statement. Then you need to cancel — which means logging in, which means a password reset, which goes to the address that no longer exists.
A disposable address turns a free trial into a subscription you can't easily cancel. The full comparison.
The setup
- A dedicated alias per trial, named for the service:
adobe-trial@yourdomain.com. - Keep it live for the whole trial. You need the reminders.
- Set your own reminder for two days before it ends. Don't rely solely on theirs — some send late, some send once, some bury it.
- Cancel through the account, not by ignoring the mail. Cancelling is what stops the charge; the address has nothing to do with it.
- Once cancelled and confirmed, disable the alias. The win-back campaigns that follow are often relentless, and now they land nowhere.
What an alias does and doesn't do here
Worth being explicit, because people occasionally believe otherwise: disabling an alias does not cancel a subscription and does not stop a payment. The card is charged regardless of whether their email reaches you. Billing and email are unconnected systems.
What the alias does is make sure you see the reminder in time, and let you shut off the marketing afterwards. Cancelling is still something you have to do.
The win-back problem
This is where trials differ from ordinary signups. Cancel a trial and you enter a specific marketing segment — "churned trial user" — which typically gets the most aggressive campaigns a company runs: discounts, urgency, repeated re-engagement over months.
Unsubscribing works if they're compliant. Disabling the alias works regardless, immediately, without a form. For a service you've decided against, that's the cleaner ending.
Trial-stacking
Some people use fresh addresses to take repeated free trials of the same service. Worth being straight about this: it generally breaches the terms you agreed to, and many services detect it by card or device anyway. Aliases are for controlling who can reach you, not for getting round terms of service — and a system built on that footing tends to collapse the first time a company enforces it.
The pattern beyond trials
The trial case generalises. Any relationship you expect to be temporary — a conference registration, a one-off download, a service you're evaluating — wants an address that works reliably for as long as the relationship lasts, then stops on your command.
That's precisely the gap between a disposable address, which stops too early, and your real address, which never stops at all.
