Cost at 50, 200 and 1,000 mailboxes
Monthly subscription, using the plan each provider recommends for that mailbox count, as of October 2026.
| Mailboxes | Winnr | Inframail (monthly) | Inframail (billed yearly) |
|---|---|---|---|
| 50 | $69 (Startup) | $147 (Unlimited) | $111.47/mo |
| 200 | $189 (Enterprise) | $147 (Unlimited) | $111.47/mo |
| 1,000 | $989 (Enterprise $189 + 800 × $1) | $387 (Agency Pack) | $293.47/mo |
Winnr Startup is $69 for 50 mailboxes plus $1 for each extra one, so it reaches Inframail's $147 at 128 mailboxes ($69 + 78 × $1). Below that, Winnr is cheaper than Inframail monthly. Against Inframail's yearly price ($111.47) the crossover is 92 mailboxes. Above those counts, Inframail's flat fee wins on subscription cost.
Two things move the totals. Domains: Winnr .com domains are about $13, one time, and connecting your own is free; Inframail charges $5 per domain to connect domains you already own. Dedicated IPs: Inframail includes 1 or 3; on Winnr they are $20 each on Enterprise, so 200 mailboxes with 1 dedicated IP would be $189 + $20 = $209 a month against Inframail's $147, which includes 1.
When Inframail is the better choice
- You run more than 128 inboxes and want one flat price that does not grow with inbox count.
- You want dedicated IPs included in the base price.
- You want a done-for-you package with domains, inboxes, warm-up, a sending platform and leads in one bill, and can commit to 3 months.
- You prefer Microsoft-backed infrastructure, as Inframail describes its inboxes.
When Winnr is the better choice
- You need fewer than 128 mailboxes. Winnr starts at $69 for 50.
- You bring your own domains. Connecting them is free on Winnr and $5 each on Inframail.
- You want warming built in at $0.60 per mailbox per month, rather than a separate warm-up tool.
- You need mailboxes that are already warm. Winnr's pre-warmed mailboxes are $3 per address per month, no base plan and no minimum term.
- You want a unified inbox and automation: the universal mailbox, a REST API, an MCP server and exports to 20+ sequencers.
