What's yours stays yours.
Most software treats an unused month like an apology you owe them. Transmit treats it as what it is: your balance.
A few years ago, someone decided that software subscriptions should work like a taxi meter with a broken clock.
You pay for capacity. You receive an allowance: thirty thousand emails, or a hundred thousand, stamped with a thirty-day expiration date. If your launch moves by two weeks, or you spend the month heads-down fixing an index instead of broadcasting product updates, the calendar flips anyway. At midnight on day thirty, the ledger resets to zero.
Nobody ever asked for that.
It was built by people who realized that if they sell you something you do not use, and take it back before you can touch it, they get to sell it to you a second time next month.
We think that is an odd way to treat a customer.
Transmit costs $20 a month. That fee is a retainer: it funds a vetted account, one verified sending domain that is entirely yours, pre-send screening, and 30,000 credits every month.
One credit is one email. If you send five thousand emails this month, twenty-five thousand remain in your account. Next month, another 30,000 arrive. They do not spoil. They do not rot on the vine. They bank quietly in your balance, building your reserves.
Credits never expire while you're subscribed. Beyond that, credits cost $0.50 per thousand.
When the morning comes that your product hits the front page, and you need sixty thousand password resets and confirmations in a single afternoon, you do not have to scramble or worry about an overage penalty. Your reserves are already waiting for you.
We do not know when your big morning will come. That is your business. Our business is to make sure that when it comes, the mail arrives, and everything you paid to put in the room is still standing there beside you.
