Choose Mailforge if you already run Salesforge and want shared-pool SMTP mailboxes from the same vendor, billed per slot. Choose Winnr if price matters more: as of October 2026, 50 mailboxes cost $69/mo on Winnr against $150/mo on Mailforge monthly billing ($125/mo on annual), and 200 mailboxes cost $189 against $581. Mailforge recommends more cold email per mailbox (30 a day against Winnr's 10 to 20), but Winnr still costs less per cold email at each provider's recommended volume.
If you are looking for a Mailforge alternative, the main questions are cost at your mailbox count, how many emails each mailbox should send, and whether you need the rest of the Salesforge family. This page answers those with Mailforge's own published numbers, checked in October 2026.
What Mailforge offers as of October 2026
- Shared infrastructure. Mailforge describes itself as distributed email infrastructure that "leverages a shared IP pool". Its sister product Infraforge uses dedicated servers, and Primeforge sells Google and Microsoft mailboxes.
- Mailbox slots, minimum 10. You pay for slots, not active mailboxes, so deleting and recreating mailboxes costs nothing extra.
- Price per slot: $3/month on monthly billing for up to 100 extra slots, stepping down by volume to $2.00 above 1,000. Annual billing is $30/year per slot ($2.50/month), described as 2 months free. The first 10 slots are always billed at the full rate.
- Domains: .com at $14/year. SSL and domain masking is a $2 per domain per month add-on.
- Sending guidance: 30 emails per mailbox per day (maximum 100), with 2 to 3 mailboxes per domain.
- No free trial, no contract, cancel anytime. Each Salesforge product is a separate subscription.

Cost at 50, 200 and 1,000 mailboxes
Mailbox subscription only, from Mailforge's pricing calculator and tier table as of October 2026. Mailforge bills the first 10 slots at $3 and the rest at the tier for that volume, so 200 mailboxes on monthly billing is 10 × $3 + 190 × $2.90 = $581.
| Mailboxes | Winnr | Mailforge (monthly billing) | Mailforge (annual billing) |
|---|---|---|---|
| 50 | $69 (Startup) | $150 | $125/mo |
| 200 | $189 (Enterprise) | $581 | $484.17/mo |
| 1,000 | $989 (Enterprise $189 + 800 × $1) | $2,109 | $1,757.50/mo |
Winnr is cheaper at every size on either Mailforge billing option: $81 a month less than Mailforge monthly at 50 mailboxes ($56 less than annual), and $1,120 less at 1,000 ($768.50 less than annual). Domains add to both: Winnr domains are a one-time purchase, about $13 for a .com (Enterprise includes 5 free domain purchases); Mailforge .com domains are $14 a year.
Monthly cost per 1,000 daily cold sends
Mailforge recommends 30 emails per mailbox per day. Winnr recommends 10 to 20 cold emails per mailbox per day (15 by default) and up to 50 in total including warming. So a Mailforge mailbox is meant to carry more cold email than a Winnr one. 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 | Mailforge at 30/day (monthly billing) |
|---|---|---|
| 50 | $69 ÷ 0.75 = $92.00 | $150 ÷ 1.5 = $100.00 |
| 200 | $189 ÷ 3 = $63.00 | $581 ÷ 6 = $96.83 |
| 1,000 | $989 ÷ 15 = $65.93 | $2,109 ÷ 30 = $70.30 |
Per cold email the gap is narrower than per mailbox, and at 50 and 1,000 mailboxes the two are within about 10%. At 20 cold a day, the top of Winnr's range, Winnr's figures fall to $69.00, $47.25 and $49.45. Mailforge allows up to 100 a day per mailbox, so if you send more than 30 from each of its mailboxes, its cost per email falls below the figures above.
When Mailforge is the better choice
- You already use Salesforge and want infrastructure, deliverability tools (Warmforge) and Google or Microsoft mailboxes (Primeforge) from one company.
- You expect a lot of spam complaints. Salesforge's own guidance is to use Mailforge's shared pool rather than Infraforge in that case.
- You prefer annual billing and want the 2-months-free discount Mailforge offers on slots.
When Winnr is the better choice
- Cost. Roughly half the price at 50 mailboxes and a third at 200, with no annual commitment needed to get the lower number.
- Lower cost per cold email at each provider's recommended sending volume, as the table above shows.
- Domains bought once (about $13 for a .com), and free connection for domains you already own.
- Warming and pre-warmed mailboxes in one place. Warming is a $0.60 per mailbox add-on, and pre-warmed mailboxes are $3 per address per month with no minimum term.
- A dedicated IP when you want one, at $20 per IP per month on Enterprise, without moving to a different product.
- Automation: full REST API, an MCP server, and exports to 20+ sequencers including Salesforge, Instantly and Smartlead.
