Inframail Pricing Behind Sales Calls? MailDeck Publishes All

Inframail does not publish pricing on its website. Teams evaluating the platform must contact sales or book a demo to receive a custom quote. MailDeck publishes every price on maildeck.co, starting at $0.30/inbox for Microsoft 365 Outlook, $0.50/inbox for SMTP, and $2.99/inbox for Google Workspace.

MailDeck provides cold email infrastructure across Microsoft 365 Outlook, Google Workspace, and SMTP, managing 833K+ inboxes for 1,631+ clients. Based on Q2 2026 MailDeck platform data.

The pricing transparency gap is the first difference, but it is far from the only one. Inframail operates as a private SMTP provider within the Salesforge ecosystem. MailDeck covers three separate infrastructure types under one provider, each with published per-inbox costs and no sales calls required to see them.

This comparison uses Inframail information from inframail.io as of May 2026 and MailDeck pricing from maildeck.co.

The Pricing Transparency Problem

When evaluating cold email infrastructure, teams need to compare costs before committing to a sales conversation. Inframail requires a sales call or demo request to receive pricing. There are no published plans, no visible per-inbox costs, and no way to estimate monthly spend without talking to their team first.

This creates friction at the evaluation stage. A team comparing five infrastructure providers can rule options in or out within minutes if pricing is public. With Inframail, they must schedule a call, wait for availability, and sit through a demo before learning whether the product fits their budget. That process can add days or weeks to a decision that should take hours.

MailDeck takes the opposite approach. Every product, every tier, and every per-inbox cost is published on maildeck.co. Teams can calculate their exact monthly spend before creating an account.

Here is what MailDeck pricing looks like across all three infrastructure types:

Microsoft 365 Outlook Tenants

Each tenant includes 100 inboxes on individual Azure tenants with dedicated US IP addresses.

Minimum order: 2 tenants (200 inboxes), $60/month. Setup time: 2-3 days.

Google Workspace Inboxes

Real Google Workspace Starter accounts on Google's own infrastructure. 5 inboxes per domain.

Minimum order: Start Up plan (10 inboxes, $39/month). Setup time: Instant.

Private SMTP

Minimum order: 100 inboxes, $50/month. Setup time: 24 hours.

Diversified Stack (All Three Combined)

Every number above is published on maildeck.co. No sales calls, no custom quotes, no demo requirements. Teams can model their costs in a spreadsheet before signing up.

Infrastructure Comparison

The pricing model is the most visible difference, but the infrastructure architecture is where these two platforms diverge fundamentally.

Inframail: Private SMTP with IP Rotation

Inframail is part of the Salesforge ecosystem and focuses on private SMTP infrastructure. Based on Inframail's website and third-party sources, the platform provides:

• Private SMTP with dedicated infrastructure
• IP rotation across sending IPs
• Automated domain provisioning with DNS configuration (SPF, DKIM, DMARC)
• Custom pricing determined through sales conversations

Inframail does not offer native Microsoft 365 Outlook inboxes or Google Workspace inboxes. All sending runs through private SMTP, which means every IP starts with zero sender reputation and must earn trust through consistent, clean sending over weeks of warmup.

The IP rotation feature helps distribute sending volume across multiple IPs, which can reduce the impact of a single IP being flagged. However, rotating across IPs that all start with zero reputation still requires the same warmup investment as building reputation on a single dedicated IP.

MailDeck: Three Infrastructure Types

MailDeck provisions three separate infrastructure types under one provider, each with a different IP model.

Microsoft 365 Outlook tenants run on individual Azure tenants with dedicated US IP addresses from Microsoft's official pools. These IPs carry pre-established trust across virtually every receiving server. Each tenant includes 100 inboxes. Warmup takes 3-7 days depending on license type.

Google Workspace inboxes are real Google Workspace Starter accounts on Google's own infrastructure. Google's sending reputation is the highest of any provider globally. Warmup takes 2-3 weeks, but deliverability is the baseline against which all other providers are measured.

Private SMTP provides dedicated IPs per client with 5 inboxes per domain. Reputation is built entirely from client sending behavior. Setup takes 24 hours, warmup takes 3-4 weeks.

Clients send 3-5 cold emails per inbox per day (Normal) or 8-10 per day (Premium) across domains with a minimum interval of 61 minutes between sends. Based on Q2 2026 MailDeck platform data.

The practical impact is twofold. First, MailDeck Outlook and Google inboxes inherit IP reputation from Microsoft and Google on day one. There is no warmup period where the IP is unknown to receiving servers. Second, running all three types under one provider creates infrastructure redundancy. If one provider tightens sending policies, the other two continue operating. For the reasoning behind infrastructure diversification, see our diversification guide.

Quick Comparison

The IP Reputation Gap

The IP layer is the most consequential infrastructure difference between these two platforms, and it affects deliverability from the first email sent.

Inframail uses private SMTP with IP rotation. These IPs start with zero sender reputation. Every new Inframail IP begins its life unknown to receiving servers and must earn trust through consistent, clean sending over weeks. IP rotation distributes volume across multiple IPs, but each IP in the rotation pool still requires the same reputation-building process.

MailDeck Outlook inboxes send through official Microsoft IP pools. These are the same IP ranges used by millions of legitimate Microsoft 365 organizations worldwide. Receiving servers already trust them because they are part of Microsoft's authenticated sending infrastructure. There is no warmup period for IP reputation, only a short warmup for the individual mailbox identity (3-7 days for Outlook).

MailDeck Google Workspace inboxes send through official Google IP pools. Google's sending infrastructure carries the highest trust score of any provider across every receiving server in the world. The warmup period (2-3 weeks) is for mailbox identity, but the underlying IP reputation is pre-established.

This distinction has a direct impact on time-to-revenue. A team spinning up 200 MailDeck Outlook inboxes can begin sending cold emails within 3-7 days. The same team on private SMTP infrastructure would need weeks of careful warmup before reaching comparable sending volumes, and deliverability during that ramp period remains uncertain because the IPs have no sending history.

For enterprise recipients running Microsoft Exchange, the gap is even wider. Exchange servers apply different trust levels to incoming mail based on whether it originates from official Microsoft infrastructure. Emails from Microsoft's own IP pools receive higher trust by default. Emails from private SMTP IPs are evaluated more skeptically.

Where Inframail Has an Advantage

Inframail's automated domain provisioning is a genuine operational advantage. The platform claims domain-to-inbox setup in under 3 minutes, including automated DNS configuration. For teams that need to spin up large numbers of domains quickly, this speed reduces the operational overhead of infrastructure management.

MailDeck Outlook tenants take 2-3 days for setup, and SMTP takes 24 hours. Google Workspace setup is instant, but domain DNS propagation still requires verification time. Inframail's automation compresses this process significantly for their private SMTP infrastructure.

Where MailDeck Wins

Published pricing with no sales calls. Every MailDeck product has its price listed on maildeck.co. Outlook Normal at $0.30/inbox, Outlook Premium at $0.40/inbox, SMTP from $0.50/inbox, Google Workspace from $2.99/inbox. Teams can calculate their exact monthly cost before creating an account. Inframail requires a sales conversation for any pricing information.

Three infrastructure types under one provider. MailDeck covers Microsoft 365 Outlook, Google Workspace, and Private SMTP. Inframail provides private SMTP only. Teams that want to match infrastructure to their target audience need multiple types. Sending Google-to-Google for enterprise Gmail users, Outlook for bulk volume, and SMTP as a buffer layer requires a provider that supports all three.

Official IP reputation from day one. MailDeck Outlook inboxes send through Microsoft's official IP pools. Google Workspace inboxes send through Google's official IP pools. Both carry pre-established sender trust that private SMTP IPs cannot replicate without weeks of warmup. Inframail's IP rotation distributes volume across multiple private IPs, but each of those IPs still starts at zero reputation.

Faster time to first send on Outlook and Google. MailDeck Outlook tenants warm up in 3-7 days. Google Workspace inboxes set up instantly (warmup still takes 2-3 weeks for optimal deliverability). Inframail's private SMTP requires weeks of warmup to build IP reputation from scratch before full-volume sending.

Scale with 833K+ inboxes under management. MailDeck manages 833K+ inboxes across 1,631+ clients, sending 7.5M+ emails per day with 98% inbox placement. The platform has delivered 270M+ cold emails lifetime across 3,000+ domains. This volume of platform data informs DNS configuration, warmup protocols, and deliverability optimization at a scale that smaller platforms cannot replicate.

Diversified stack plans. MailDeck's Diversified Stack combines all three infrastructure types in one plan: Starter at $99/month (200 Outlook Premium + 10 SMTP + 5 Google), Growth at $399/month (1,000 Outlook Premium + 100 SMTP + 30 Google), and Enterprise at $3,499/month (10,000 Outlook Premium + 1,000 SMTP + 300 Google). Inframail does not offer a diversified infrastructure option because it operates on private SMTP only.

Zero shared IP risk. MailDeck Outlook and Google inboxes use official provider IP pools with pre-established trust. MailDeck SMTP uses dedicated IPs per client. No MailDeck product exposes clients to shared IP risk where another sender's behavior could damage their reputation.

Why Pricing Transparency Matters for Cold Email Infrastructure

Hidden pricing creates a structural disadvantage for buyers evaluating cold email infrastructure. Here is why it matters beyond simple convenience.

Budget planning becomes guesswork. Teams cannot model infrastructure costs against projected campaign ROI without knowing what the infrastructure costs. If pricing requires a sales call, the financial planning that should happen before the first conversation with a vendor gets pushed to after the call. This reverses the normal evaluation process.

Comparison shopping requires more time. A team evaluating five providers can compare the four with published pricing in an afternoon. The fifth requires scheduling a call, waiting for availability, receiving a quote, and then comparing. The provider with hidden pricing adds days to a process that should take hours.

Custom pricing introduces negotiation uncertainty. When pricing is determined through sales conversations, different teams may receive different quotes for the same product. Published pricing eliminates this variable. Every MailDeck client pays the same per-inbox rate regardless of their negotiation skills or the sales rep they speak with.

Scaling costs become predictable. With published per-inbox pricing, teams can calculate exactly what it costs to go from 500 inboxes to 5,000 inboxes. The math is simple multiplication. With custom pricing, scaling requires another sales conversation to learn whether volume discounts apply and at what thresholds.

Sequencer Compatibility

Neither Inframail nor MailDeck includes a built-in email sequencer. Both provide inbox infrastructure that connects to external sequencers via SMTP credentials.

Inframail integrates with Instantly, Smartlead, and Reachinbox based on their website.

MailDeck provides SMTP credentials compatible with any sequencer that supports SMTP connections: Instantly, Smartlead, Saleshandy, Apollo, Lemlist, Woodpecker, Reply.io, Snov.io, QuickMail, and any other SMTP-compatible tool.

The sequencer does not affect deliverability. It is a scheduler. The inbox type determines approximately 60% of deliverability. The remaining 40% comes from domain health and copy quality.
