Infraforge
Alternative & Review

Infraforge.ai is a private cold email infrastructure product in the Forge ecosystem. Its official homepage describes the platform as advanced private email infrastructure that lets teams create thousands of domains and mailboxes with a dedicated IP and automated DNS setup, or use prewarmed infrastructure for immediate sending.[1] The product is positioned for teams that want more control than they would get from generic mailbox procurement, especially agencies, lead generation providers, and outbound sales teams managing high-volume sending.

The official About page frames Infraforge as part of the broader Forge ecosystem created by Frank Sondors, Dovydas Volodko, and Daniel Sanchez after meeting through Y Combinator's founder matching platform in January 2023. Salesforge went live on June 15, 2023; Mailforge launched in January 2024 as shared cold email infrastructure; and Infraforge debuted in July 2024 as private email infrastructure.[6] The publicly extracted official About page did not specify a headquarters location, so this comparison does not infer one.

Infraforge's main difference is private infrastructure with dedicated IPs. The homepage emphasizes dedicated IPs, automated warmup and monitoring, built-in sender rotation, smart sending limits, automated DNS setup, bulk DNS updates, domain transferring, SSL and proxies, and compatibility with Salesforge and other sending tools.[1] A Salesforge directory page describes Infraforge as a high-performance private cold email infrastructure platform for teams that need complete control over their sending environment, with dedicated IPs, multi-IP provisioning, free DNS setup, API access, SSL/domain masking, performance visibility, flexible scaling, and a white-label reseller program.[7]

Infraforge does not present a simple public customer-count metric in the extracted official page text. The homepage does show an example interface with 144 active domains, 2,000 mailbox slots, 574 active mailboxes, and 4 dedicated IPs, but this appears to be a product illustration rather than a verified total customer or mailbox count.[1] The strongest official scale claim is that teams can set up unlimited domains and mailboxes and that the platform is designed for creating thousands of domains and mailboxes.[1]

"Infraforge - used it briefly when someone in a discord recommended it. it was alright for outlook accounts. nothing really wrong with it but nothing that stood out either. felt like a mailforge alternative without any real advantage over mailforge. tried it for a couple campaigns and just went back to what i was already using." – every cold email tool ive used in the last 2 years ranked by whether i still use it or not

"I use mailforge. I have a handful of clients I operate for on Mailforge. Mailforge is on a shared IP, which from my experience, has great deliverability. The same company has infraforge which operates on a private IP. We ran some tests and our deliverability was worse on infraforge." – Are Cold Email Infrastructure tools worth it?

🟢 Dedicated IP infrastructure: Infraforge is built around private infrastructure and dedicated IPs, which can be attractive for teams that want isolation instead of shared infrastructure.
🟢 Automated DNS setup: SPF, DKIM, DMARC, and domain configuration can become a major operational bottleneck at scale. Infraforge highlights automated DNS setup and bulk DNS updates.
🟢 API access: The pricing page states that access to the Infraforge API is included with the subscription, which is useful for agencies and technical teams automating infrastructure workflows.
🟢 White-label and reseller angle: Infraforge promotes a reseller program with 20% revenue share and white-label capabilities, which may fit agencies selling infrastructure as part of a service package.

🔴 Dedicated IPs add cost and responsibility: Infraforge lists IP addresses as a $99 per IP per month add-on when billed quarterly. Dedicated IPs can improve control, but they also require careful reputation management and can raise total cost.
🔴 Minimum and add-on structure is less straightforward than simple mailbox pricing: The pricing calculator includes mailbox slots, domains, SSL/domain masking, IPs, and Masterbox as separate cost components. This can make budgeting harder for teams that want a simple per-mailbox model.
🔴 No clearly disclosed official money-back guarantee in the public pricing text examined: The extracted official pricing page includes subscription inclusions and add-ons, but it does not show refund terms comparable to Maildoso's explicit 30-day money-back guarantee.
🔴 Trial terms are not fully transparent on the pricing page: Infraforge has "Try it for free" CTAs and an FAQ question about a free trial, but the extracted public page text does not expose exact trial terms. One accessible third-party review describes Infraforge as having no free trial, so buyers should verify terms before committing.

Maildoso is a cold outreach infrastructure provider – we offer domains, SMTP mailboxes, and Google Workspace accounts. The company was founded in August 2023 in Granite Bay, California, by Nikita Bykadarov (Nikita Maildoso).

While other providers offer shared or dedicated IPs, we have developed IP rotation. This means your emails are sent from hundreds of different IPs (making it harder for spam filters to detect a sending pattern), and whenever any IP gets blacklisted, we automatically swap it out for a clean one.

We have also implemented self-healing mailbox technology, which both restores burned-out mailboxes and protects your active email accounts.

The result? As of May 2026, the spam rate across our entire network of mailboxes is around 5%.

"Tried it mainly because of the good price, but ended up sticking with it since deliverability’s been pretty stable so far" – Thinking about trying "Maildoso". Has anyone here used it? Is it actually better than other tools?

"I tested a small batch first and results were comparable to our Google setup. Ended up moving more campaigns there because of the lower cost. That's a good strategy, buy small package and compare with your current setup" – I want to try Maildoso. What do you guys think about it?

🟢 Dynamic IP Rotation: We rotate your IP addresses in real-time – if an IP gets flagged or blacklisted, we instantly swap it for a clean one before your campaign takes a hit.
🟢 Self-Healing Rotation: An automated resting period for mailboxes every two weeks that clears provider flags and recovers reputation on autopilot.
🟢 API & MCP Automation: Create domains and mailboxes, export to your sequencer in one call – or manage it all from your AI assistant through our MCP server.

🔴 Conservative Limits: We suggest sticking to 15 emails a day per box to keep your domains healthy for the long run.
🔴 Google/SMTP Focus: We do not support Microsoft 365/Outlook/Azure environments at this time.
🔴 Lack of built-in warmup. We do not have an integrated warm-up yet, but we are currently working on it.

It’s tempting to choose a provider based solely on the lowest price, but budget infrastructure often leads to hidden costs. When deliverability drops, the consequences usually show up in three areas:

• Burned Leads: High-quality B2B data is expensive. If emails land in spam, those contacts never see the pitch, and the budget spent on data is lost.
• Damaged Domains: Fixing a domain flagged by spam filters can be a massive headache. Often, it’s easier to just buy a new one and start the warm-up process all over again.
• Missed Revenue: Every missed inbox is a missed meeting. In B2B sales, losing even one connection can mean missing out on thousands in closed revenue.

Cold email infrastructure is better viewed as an investment. Maildoso provides the technical tools to protect domain reputation and help keep emails in the primary inbox.

It’s great that Infraforge offers dedicated IPs (but mind that it costs $99/mo – the highest price on the market). However, based on our experience and what new clients tell us during demos, dedicated servers alone aren't enough for stable mailbox performance. When your IP sends a high volume of similar emails, it becomes much easier for filters to track.

With Maildoso, your emails are sent from thousands of different IPs that are constantly rotating. These IPs also handle traffic from other senders – this completely confuses spam filters and prevents them from identifying sending patterns.
Most importantly, if an issue arises with any specific IP, we simply disable it and replace it with a clean one. This happens automatically in a fraction of a second; you won't even notice.

And let’s be honest: Infraforge' lowest price per mailbox is still higher than Maildoso's highest price. There’s really no reason to overpay.
