"Limited" means available but not direct. Infraforge points you to real Google and Microsoft mailboxes through sister products in the Salesforge family rather than selling them itself, and Inframail's own sending platform sits on its done-for-you tier. "Not named" means the integration is not listed on the official site.
What real users say
Public review scores and the themes that come up most, checked June 2026. Counts drift, so the live links are the source of truth.
Infraforge
Praised for: dedicated IPs with multi-IP provisioning and rotation, granular control over the sending stack, prewarmed infrastructure, and the wider Salesforge ecosystem around it.
Watch-outs: no free trial, so you commit before testing, per-resource cost that adds up as you scale, and it can be more than a small team needs.
Inframail
Praised for: speed to spin up unlimited Outlook inboxes, predictable flat cost, a clean setup, and a dedicated IP plus deliverability consultant included.
Watch-outs: Outlook only, which hurts Gmail-heavy prospect lists, limited integrations, and a cost that some reviewers feel is high relative to the feature set.
Read the scores in context. Each tool's one solid review sample sits on a different platform, Infraforge on G2 and Inframail on Trustpilot, and neither has a meaningful Capterra base yet. So weigh the themes and the sample size alongside the score, rather than reading too much into the headline number.
Where each one actually wins
Six things separate these tools in practice. Here is the honest call on each.
Pricing model, modular vs flat unlimited
Edge: dependsThis is the issue that defines the choice. Infraforge bills per resource, so you assemble mailbox slots, domains, IPs, and add-ons, and the cost tracks exactly what you provision. Inframail charges a flat monthly fee for unlimited Outlook inboxes, so the per-inbox cost falls as you add more. Neither is cheaper outright. The right one depends on how many inboxes you run and whether Microsoft-only fits.
Google plus Microsoft coverage vs Outlook-only
Edge: InfraforgeInframail provisions Microsoft Outlook inboxes only, which is fine until your prospect list skews Gmail. Infraforge does not sell Google or Microsoft mailboxes directly, but real Google and Microsoft inboxes are available through sister products in the Salesforge family, so the Infraforge stack can cover both. If you need Google as well as Microsoft, Infraforge has the edge.
Dedicated-IP control and rotation
Edge: InfraforgeBoth include dedicated IPs, but the control differs. Infraforge sells dedicated IPs at $99 per IP a month with multi-IP provisioning, sender rotation, and smart sending limits, which is the core of the product. Inframail bundles one US IP on Unlimited and three on Agency into the flat price, without granular rotation control. If IP reputation engineering matters to you, Infraforge gives more to work with.
Simplicity and predictability
Edge: InframailInframail is the simpler buy. One flat price, unlimited Outlook inboxes, free setup, and a predictable monthly bill, with no per-inbox math to do. Infraforge is more powerful but asks more of you, since you assemble slots, domains, IPs, and add-ons yourself. If you want to spin up inboxes fast without managing a stack, Inframail is the easier path.
Ecosystem and tooling
Edge: InfraforgeInfraforge sits inside the Salesforge family, so the infrastructure plugs into a sender, a warmup tool, and mailbox products that share the same stack. Inframail is mostly standalone, with its own done-for-you service layer on the top tier. If you want infra and the surrounding tooling from one ecosystem, Infraforge has more around it.
Cost at high inbox counts
Edge: InframailBecause Infraforge bills per slot, cost scales linearly with inbox count, so a large fleet adds up. Inframail's flat fee keeps the per-inbox cost falling as you add more, as long as you stay under the monthly email caps. Past a few hundred Outlook inboxes, Inframail's flat model tends to win on price, provided Microsoft-only works for you.

What each one costs in 2026
Verified from each official pricing page in June 2026. Read the model, not just the headline number.

Microsoft Outlook only. No free trial. Flat unlimited-inbox pricing rather than per mailbox.
True cost at scale. Infraforge bills per resource, so cost tracks exactly what you provision, and you keep dedicated-IP control plus a Google or Microsoft choice. Inframail is flat unlimited on Outlook, so a large fleet of inboxes can be cheaper to run, as long as Microsoft-only fits your sending. Past a few hundred Outlook inboxes, Inframail's flat model tends to win on price. Infraforge wins when you need Google, granular control, or the Salesforge ecosystem.
What neither tool does well
Both are infrastructure, the pipes, not the campaign. Worth knowing before you expect either to carry your whole motion.
Infrastructure is the pipes, not the campaign. You still need a sending tool and sequences on top of either one.
Neither finds or times the right accounts. That is targeting, and it sits well above the inbox layer.
Self-hosting your own infra adds setup and monitoring work, so it pays off only at real volume.

Our take, after running both
The choice is mostly about your model and mailbox needs, not a feature count. Here is how we'd call it in three situations.
Dedicated-IP control, Google or Microsoft, rotation, and the Salesforge ecosystem suit teams that want to engineer deliverability.
Unlimited Outlook inboxes on one predictable bill fit Outlook-heavy teams that need inbox quantity fast without managing a stack.
Infrastructure is the pipes, not the campaign. Put a sender and sequences on top of either, and add targeting above that.
