Cost at 50, 200 and 1,000 mailboxes
Mailbox subscription only, from Infraforge's calculator and tier table as of October 2026. Infraforge bills the first 10 slots at the full rate and the rest at the volume tier, so 200 mailboxes on quarterly billing is (10 × $12 + 190 × $11.70) ÷ 3 = $781 a month.
| Mailboxes | Winnr (monthly) | Infraforge (quarterly billing) | Infraforge (annual billing) |
|---|---|---|---|
| 50 | $69 (Startup) | $200/mo ($600 per quarter) | $166.67/mo |
| 200 | $189 (Enterprise) | $781/mo | $650.83/mo |
| 1,000 | $989 (Enterprise $189 + 800 × $1) | $3,109/mo | $2,590.83/mo |
Adding one dedicated IP: Winnr Enterprise with 200 mailboxes and 1 IP is $189 + $20 = $209/mo. Infraforge with 200 mailboxes and 1 extra IP address is $781 + $99 = $880/mo on quarterly billing. Infraforge already runs on dedicated servers, so whether you need the extra IP depends on your setup; the add-on price is what the pricing page lists.
Monthly cost per 1,000 daily cold sends
Infraforge recommends 30 emails per mailbox per day; Winnr recommends 10 to 20 cold emails per mailbox per day (15 by default), with up to 50 in total including warming. Taking each provider's recommendation, here is what 1,000 cold emails a day of capacity costs (monthly price ÷ cold emails per day in thousands):
| Mailboxes | Winnr at 15/day | Infraforge at 30/day (quarterly) |
|---|---|---|
| 50 | $69 ÷ 0.75 = $92.00 | $200 ÷ 1.5 = $133.33 |
| 200 | $189 ÷ 3 = $63.00 | $781 ÷ 6 = $130.17 |
| 1,000 | $989 ÷ 15 = $65.93 | $3,109 ÷ 30 = $103.63 |
Infraforge mailboxes are meant to carry twice as much cold email as Winnr's default, which narrows the gap, but Winnr is still cheaper per cold email at every size. Infraforge allows up to 100 a day per mailbox, so sending more than 30 from each would lower its figures.
When Infraforge is the better choice
- You want Salesforge's ecosystem: the Salesforge sequencer, Primeforge for Google and Microsoft mailboxes, and Infraforge under one company.
- You run an agency that needs separate workspaces per client, with a combined Masterbox view per workspace.
- You want to resell infrastructure under your own brand. Infraforge offers a whitelabel program.
- You are happy to commit quarterly or annually in exchange for dedicated-server infrastructure.
When Winnr is the better choice

- Price. About a third of Infraforge's quarterly price at 50 mailboxes and a quarter at 200.
- Cheaper dedicated IPs: $20 per IP per month on Enterprise (how they work).
- A unified inbox at no extra charge: the universal mailbox shows replies from every account in one place.
- Domains bought once (about $13 for a .com), and free connection for domains you already own.
- Warming and pre-warmed mailboxes in the same dashboard ($0.60 per mailbox and $3 per address per month).
