Infraforge is the private cold email infrastructure product in the Salesforge family, sitting alongside Salesforge for sequencing, Primeforge for Google and Microsoft mailboxes, Mailforge for shared infrastructure, Warmforge for deliverability and Leadsforge for data. Six products, six pricing pages, six logins.
That structure is the single most important thing to understand before you evaluate Infraforge, because it shapes both what the product is good at and what it costs you in practice.
What Infraforge actually does well
Three things, genuinely.
Dedicated IPs, properly implemented. This is the core of the product and the reason to buy it. Your sending reputation is yours. Nobody else’s cold campaign can put your IP on a blocklist. For any team past a few thousand sends a month, that is the difference between deliverability you can debug and deliverability you can only pray about.
DNS automation. SPF, DKIM, DMARC and PTR configured automatically when a domain is added. This sounds minor until you have manually configured DNS for the fortieth domain and introduced a typo you will not discover for two weeks, by which point a campaign has already been landing in spam.
Domain masking and pre-warmed domains. Both reduce the setup lag between buying infrastructure and being able to send safely. Pre-warmed inventory in particular is a real time saving if you need to be live this week rather than next month.
The engineering is not the problem. Their blog is full of DNS rate-limiting and SPF-lookup detail written by people who clearly run this stuff. If you are judging Infraforge purely on whether the infrastructure works, it works.
Where it gets expensive
The billing model
Infrastructure sold on an annual commitment prices your peak month as your baseline for twelve months. That is fine for a company with steady outbound. It is a genuine problem in three common situations: agencies whose client roster changes quarterly, seasonal businesses, and any team that does not yet know how many mailboxes it needs and is being asked to commit before finding out.
The workaround people use is to under-commit and top up, which means running two providers, which defeats the point.
The stack tax
Here is the part that catches teams out. Infraforge is infrastructure. To actually run outbound you also need:
- A sequencer, Salesforge, or a third party.
- Warmup, Warmforge, or a third party.
- Real Google or Microsoft mailboxes for your higher-trust campaigns, Primeforge.
- Lead data, Leadsforge, or Apollo, or Clay.
Every one of those is a separate subscription with its own renewal date and its own seat count. The individual prices all look reasonable. The total, once you have assembled a working outbound motion, usually surprises people. Price the stack, not the component.
Debugging across product boundaries
When a campaign underperforms, the cause could be the copy, the list, the mailbox, the domain, the IP or the warmup. When those live in five products, tracing it is five dashboards and a lot of guessing. This is the quiet operational cost of a multi-product stack and it does not show up on any pricing page.
Who Infraforge is genuinely right for
Teams already committed to the Salesforge ecosystem, running Salesforge for sequencing and Primeforge for mailboxes, with steady high volume and an annual budget that is already approved. In that situation the cross-product integration is real and the commitment is not painful, and switching one component out would cost more than it saves.
Who should look elsewhere
Anyone with variable volume. Agencies especially. If your sending drops 40% when a client churns, monthly billing is worth more than any feature.
Teams who want one platform. If the appeal of infrastructure was fewer moving parts, buying it as a sixth subscription is going the wrong way.
Teams under about 5,000 sends a month. Private infrastructure is over-engineered at that volume. Real Google or Microsoft mailboxes will serve you better and cost less.
What I’d use instead
For private infrastructure with the same fundamentals and a different commercial model, Mailboundry. Dedicated IP per mailbox, SPF, DKIM and DMARC generated automatically and updatable in bulk across every domain, domains purchasable inside the app up to $14 per TLD, SSL and link masking, and separate workspaces for agency clients.
The differences that matter against Infraforge are commercial, not technical: monthly, quarterly or annual billing across five volume tiers rather than one annual commitment; and it is included in the Outboundry subscription alongside cold email, LinkedIn, lead data, unlimited warmup, AI personalization and the Reply Agent rather than sold as a sixth product.
If your campaigns need real Google or Microsoft mailboxes rather than private SMTP, those are $4 per mailbox per month in the same platform, with DNS handled for you.
The verdict
Infraforge is a well-built piece of infrastructure with a commercial model that suits a specific kind of buyer: large, stable, already inside the ecosystem, annual budget signed off. If that is you, it is a reasonable choice and you should ignore most of this review.
If you are an agency, a lean team, or anyone whose sending volume moves month to month, the annual commitment and the stacked subscriptions are the two things that will bother you a year from now, and both are avoidable.

Frequently asked questions
Is Infraforge worth it?
For teams already running the wider Salesforge stack and sending consistent high volume on an annual budget, yes. The infrastructure engineering is solid. For teams with variable volume, or teams who only want infrastructure and not the surrounding ecosystem, the commercial model is where it starts to hurt.
How much does Infraforge cost?
Pricing is tiered by the number of mailboxes and domains and is published on their pricing page. Check it directly before deciding, because the number that matters is not the infrastructure line on its own but the total of infrastructure, mailboxes, warmup, data and your sequencer.
What is the difference between Infraforge and Mailforge?
Infraforge is private infrastructure with dedicated IPs. Mailforge is shared, distributed infrastructure where your sending shares reputation with other senders. Private costs more and isolates your reputation; shared is cheaper and does not.
What is the best Infraforge alternative?
Mailboundry if you want the same private-infrastructure model with monthly billing and outreach bundled in. Google or Microsoft mailboxes if you are lower volume and want maximum sender trust. Self-hosting if you have a systems engineer and a reason.
Does Infraforge include warmup?
Warmup in the Salesforge ecosystem is largely handled by Warmforge, a separate product. That is the pattern across the stack, and it is the main thing to account for when you price the whole setup rather than one component.
