The catalog price of a one-off email activation isn't a flat rate for "mail in general" — it's the result of several factors combined at the moment you order. Here's what goes into that price, why it moves, what exactly you're charged for, and when renting a mailbox is cheaper than a stream of one-off purchases.
What makes up the price of one activation
The first component is the wholesale cost from the mailbox supplier. The platform doesn't build its own mail infrastructure from scratch — it buys capacity from suppliers, and the catalog price is that cost plus a margin, not an arbitrary figure.
The second component is the specific site the address is ordered for: popular destinations with high signup volume cost more, because the share of failed attempts on them is higher and that's priced in ahead of time, not because the mailbox itself is any different. The third component is the chosen domain: price applies to the whole "site plus domain" pair, not the domain alone, which is why the same domain costs differently paired with different sites. The fourth is current availability: when free addresses for the pair you need are scarce, price shifts up, and it eases back down once the pool refills.
Why the same pair costs differently at different times
The catalog doesn't work like a price list fixed a month in advance. Availability for a given pair changes in real time: some addresses are tied up in active activations, others just freed up, and demand for popular pairs swings over the course of a day. A burst of orders on one pair temporarily pushes its price up; a refill or a drop in demand brings it back down. That's the normal mechanics of a live stock, not erratic storefront behavior.
You only pay for a result
An activation lives for 20 minutes from the moment of purchase. If the code hasn't arrived by then, the activation closes on timeout automatically and the money is refunded to the balance without a support request. You can also cancel it manually earlier — the outcome for your balance is the same either way: a charge is recorded only for a code you actually received, not for the fact that an address was issued. The refund and charge history for every activation is visible in the transactions section.
How to compare price honestly: by the cost of a successful verification
Comparing two site-plus-domain pairs by the catalog figure alone is misleading. A refund on failure removes the financial risk of one attempt, but not the lost time: if the cheaper pair regularly times out while the pricier one comes through reliably, the real cost of a successful result on the cheap pair ends up higher, not lower — reaching the code takes several attempts instead of one. Honest comparison means weighing price against how often the pair actually delivers a code, not the bare price of a single attempt: that figure, not the storefront price, reflects what a confirmed signup actually costs.
When renting a mailbox beats a stream of one-off activations
If the task isn't one code for one signup but a series of emails from the same site over time, a stream of one-off activations starts losing to a rental: every new activation means going through the waiting window again and paying again for the fact of receiving a code. A rented mailbox runs from 12 hours to 60 days with preset terms and extension support, and the mailbox itself accepts mail only from the sites listed at order time — that's a difference in the payment model, not just a longer timer. The current price for a specific pair or a specific rental term is visible right on the order page before you buy — it's recalculated against current availability and won't match last week's figure.
Frequently Asked Questions
Will I be charged if the email with the code doesn't arrive in time?
No. If the code doesn't arrive within 20 minutes, the activation closes on timeout and the money is refunded to the balance automatically, with no separate support request.
Why does the price for the same site-plus-domain pair change during the day?
Price reacts to current address availability for that pair and to demand: a burst of orders temporarily raises the price, while a refill or a drop in demand brings it back to normal.
What's cheaper — several one-off activations in a row, or renting a mailbox?
For a single signup with one code, a one-off activation is usually cheaper. If the site sends several emails over time, a mailbox rental avoids paying again for every new waiting cycle.
