DuoboxThe promo price and the one you pay later
This page is for anyone who saw Hostinger's email for under a dollar and wants to know what's in the fine print before paying. We read the prices on Hostinger's official site on 26 October 2026, in dollars.
Hostinger's small number is real. It's just that you pay it all together, up front, and then it changes. On Duobox the smallest number is zero, and there's nothing to pay in advance.
Your first inbox is free
On Duobox you start without paying: 1 person, 1 inbox, 1 domain and 10 GB, no card and no time limit. It's not a promotion with an expiry date or a price that multiplies at renewal: it's the plan, and it stays that way as long as you're one person.
At Hostinger, the cheapest address is $0.39 a month, but for that price you pay all 48 months at once. And it comes with 5 GB, half of what you get free on Duobox.

|---|---|---|
| 1 person | $0 | $18.72 up front (48 months), and then $1.59 a month |

When to choose each one
DuoboxChoose Duobox if you want to start free, your team shares inboxes, people come and go, you'd rather pay month to month, and you want an agent that can work right in there.
Choose Hostinger if you're a team of one, you're comfortable paying four years up front and 5 GB is enough.
And if your website is at Hostinger, you can combine them: the website stays there and the email goes on Duobox. You connect them by copying a few records into your domain's DNS.
Questions we get
- Is the first inbox free forever?
- Yes, as long as you're one person with one inbox and 10 GB. You only pay when you add someone, a second inbox or more storage.
- Can I keep my website at Hostinger and my email at Duobox?
- Yes. The website uses some of the domain's records and the email uses others; they don't step on each other.
- How long does the move take?
- Connecting the domain means copying a few records. Bringing over your old email is an IMAP import.
