Introduction
Infraforge has carved out a niche in the cold email infrastructure space by focusing heavily on dedicated IPs and multi-IP provisioning. If you've been comparing cold email SMTP providers, you've probably seen Infraforge come up alongside Winnr, Maildoso, and Mailforge.
But how do the two actually compare? This guide breaks down pricing, billing flexibility, dedicated IP features, API access, and deliverability — so you can decide which platform makes sense for your outreach operation.
Pricing: Winnr Is 40–65% Cheaper at Every Tier
Infraforge starts at $40/month for 10 mailboxes, which works out to $4 per mailbox. At higher volumes, that per-mailbox cost drops to roughly $2.50 — but you need to commit to a large quarterly or annual plan to get there.
Winnr's Startup plan starts at $69/month for 50 mailboxes, which comes to just $1.38 per mailbox. That's 65% cheaper than Infraforge's entry pricing and still 40–45% cheaper than Infraforge's best volume rates.
At 50 mailboxes, you'd pay roughly $125–200/month on Infraforge. On Winnr, it's $69. The math isn't close.
For teams scaling to 100+ mailboxes, the gap widens even further. Winnr's Growth plan offers 200 mailboxes for $169/month ($0.85/mailbox), while Infraforge's equivalent volume would run $250–400+ depending on your contract term.
Billing Flexibility: Month-to-Month vs Quarterly Lock-In
This is one of the biggest practical differences between the two platforms — and it's a dealbreaker for many teams.
Infraforge does not offer month-to-month billing. Their minimum commitment is quarterly, with discounts only available on annual plans. This means you're committing at least $120+ upfront before you've sent a single email — with no way to cancel mid-cycle if the platform doesn't meet your needs.
Winnr bills monthly with no long-term commitment required. You can sign up, test the platform, and cancel anytime. This is particularly important for teams that are:
- Testing a new infrastructure provider for the first time
- Running seasonal campaigns that don't need year-round infrastructure
- Agencies onboarding new clients who may churn after a few months
- Bootstrapped teams that need to control cash flow tightly
Quarterly billing is a significant barrier to entry. If you're not certain Infraforge is the right fit, you're gambling three months of spend to find out.
Dedicated IPs: Infraforge's Core Strength
Credit where it's due — Infraforge's dedicated IP infrastructure is genuinely strong. Their platform is built around multi-IP provisioning and rotation, which lets you:
- Assign dedicated IPs to individual clients or campaigns
- Rotate across multiple IPs to distribute sending volume
- Isolate IP reputation between different sending pools
For agencies managing 10+ clients who each need fully isolated sending infrastructure, Infraforge's granular IP management is a meaningful advantage.
How Winnr Handles IPs
Winnr takes a different approach depending on your plan:
- Startup plan ($69/mo): Shared IP pools with intelligent rotation. Winnr actively monitors and maintains pool health, ensuring that bad actors are removed quickly and IP reputation stays high.
- Enterprise plan ($20/mo per mailbox): Dedicated IPs with full isolation. Ideal for high-volume senders who need complete control over their IP reputation.
For the majority of cold email senders — those running 50–200 mailboxes for their own outreach — Winnr's shared pools deliver comparable deliverability at a fraction of the cost. Dedicated IPs become critical mainly when you're an agency isolating per-client infrastructure.
Feature Comparison

| REST API | Yes — full provisioning API | Limited |
| Dedicated IPs | Enterprise plan ($20/mo) | Yes — all plans |
| IP Rotation | Automatic (shared pools) | Multi-IP provisioning & rotation |
| Bring Your Own Domain | Yes | Yes |
| Deliverability Guarantee | Yes — domain replacement | No public guarantee |
| Billing | Monthly, no commitment | Quarterly or annual only |
| Price for 50 Mailboxes | $69/mo | ~$125–200/mo |
| Support | Live chat + email | Email support |
The Honest Trade-Off
Here's the reality: Infraforge wins for agencies that need granular multi-IP isolation per client. If you're managing 15 clients and each one needs their own dedicated IP pool with independent reputation tracking, Infraforge's tooling is purpose-built for that use case.
But that's a narrow segment of the market. For the other 80% of cold email senders — solo operators, in-house sales teams, small agencies, and growing startups — Winnr delivers comparable deliverability at half the cost, with the flexibility to pay monthly and scale up or down as needed.
Choose Infraforge if you're an agency needing per-client IP isolation and you're comfortable with quarterly billing. Choose Winnr if you want the best price-to-performance ratio with monthly flexibility and automated infrastructure.
Who Should Choose Winnr Over Infraforge?
- Cost-conscious teams: 40–65% savings per mailbox adds up fast at scale.
- Teams that want to test before committing: Monthly billing means zero risk to try.
- API-first workflows: Winnr's full provisioning API lets you automate account creation, DNS setup, and management programmatically.
- Fast-scaling outreach operations: Spin up 50+ accounts in minutes with automatic DNS configuration — no manual setup required.
Who Should Choose Infraforge?
- Large agencies with per-client IP requirements: If every client needs isolated IP reputation, Infraforge's multi-IP tooling is best-in-class.
- Teams committed to long-term contracts: If you know you'll need infrastructure for 12+ months and want IP-level control, the quarterly billing is less of a friction point.
Frequently Asked Questions
Does Infraforge have monthly billing?
No. Infraforge requires a minimum quarterly commitment. There is no month-to-month option. If you want to test the platform, you'll need to commit to at least three months upfront. Winnr offers fully flexible monthly billing with no contracts.
Is Winnr cheaper than Infraforge?
Yes — significantly. Winnr's Startup plan is $69/month for 50 mailboxes ($1.38/mailbox), compared to Infraforge's ~$125–200 for the same volume ($2.50–4.00/mailbox). That's a 40–65% savings depending on Infraforge's plan tier and billing cycle.
Which platform has better dedicated IPs?
Infraforge has more granular multi-IP provisioning and rotation controls, which makes it stronger for agencies that need per-client IP isolation. Winnr offers dedicated IPs on its Enterprise plan and well-maintained shared IP pools on its Startup and Growth plans that deliver strong deliverability for most use cases.
Can I test Infraforge before committing?
Not easily. Infraforge's minimum billing cycle is quarterly, so you're committing at least three months of spend upfront. With Winnr, you can sign up on a monthly plan, test the platform with real campaigns, and cancel anytime if it's not the right fit — no risk, no long-term lock-in.
Does Winnr have an API?
Yes. Winnr offers a full REST API for provisioning mailboxes, managing domains, configuring DNS, and monitoring account status programmatically. This makes it ideal for agencies and teams that want to automate their infrastructure workflows. Infraforge's API access is more limited.
