What is Deliverability.gg?

Deliverability.gg is a Microsoft-partnered inbox provider that provisions Outlook-based email infrastructure specifically for outbound email campaigns. As a registered Microsoft cloud service partner, the platform delivers enterprise-grade sender reputation and deliverability characteristics without the cost structure typically associated with premium managed infrastructure.

The service positions itself on speed and pricing transparency, offering “distributor-level pricing with no middleman markups” and 24-hour inbox capacity from domain verification to live sending. By standardizing on Microsoft/Outlook infrastructure, Deliverability.gg aligns outbound senders with the reputation patterns and technical frameworks familiar to enterprise recipients and spam filters.

Unlike shared consumer email services or general-purpose SMTP providers, Deliverability.gg focuses exclusively on provisioning and managing Outlook mailboxes optimized for cold outreach workflows. The platform handles domain authentication configuration and infrastructure setup, allowing revenue teams to launch sending capacity quickly without navigating Microsoft’s enterprise onboarding processes independently.

Core Services

Microsoft-Partnered Infrastructure

Deliverability.gg’s core offering is Outlook-based mailbox infrastructure provisioned through a registered Microsoft cloud service partnership. This partnership provides direct access to Microsoft’s email ecosystem, enabling the platform to allocate inboxes that inherit enterprise sender reputation characteristics rather than consumer-grade restrictions common to standalone Outlook.com accounts.

The Microsoft infrastructure alignment positions senders with technical signals and IP reputation profiles recognized favorably by corporate spam filters, particularly those protecting Microsoft 365 and Outlook recipients. This infrastructure consistency aims to reduce the cold-start reputation challenges faced when launching new sending domains on less-recognized SMTP providers.

Domain Setup and Authentication

When customers share domain details, Deliverability.gg configures SPF, DKIM, and DMARC records aligned with Microsoft’s authentication requirements. These configurations are implemented as part of the provisioning process, ensuring that mailboxes meet Microsoft’s 2025 bulk sender authentication mandates before the first email is sent.

The service follows a three-step setup workflow: customers submit sending requirements and domain information, Deliverability.gg provisions Outlook-based inboxes with complete authentication configuration, and credentials are loaded into the customer’s sending tool of choice. This turnkey approach removes manual DNS troubleshooting and record propagation delays.

Mailbox Management and Provisioning

Inbox capacity is delivered within 24 hours after domain verification and admin approval. The platform provisions mailboxes directly through Microsoft’s infrastructure, providing SMTP credentials compatible with standard cold email sequencers and sales engagement platforms. The rapid provisioning timeline allows operators to scale sending capacity or replace flagged domains without extended downtime.

Mailbox management details—including account rotation strategies, inbox monitoring, and health dashboards—are not publicly documented and likely require direct engagement with the Deliverability.gg team to understand operational workflows.

Deliverability Operations

Deliverability.gg enables next-day warmup initiation following inbox provisioning, leveraging Microsoft infrastructure to establish sender reputation. The platform claims “industry-leading deliverability” based on the Microsoft partnership and enterprise-aligned infrastructure, though specific inbox placement percentages, warmup protocols, and performance benchmarks are not publicly shared.

The absence of published case studies or customer testimonials means deliverability claims remain unverified by independent operators. Teams evaluating the service should request reference customers or trial data to validate inbox placement performance for their specific sending profiles and target audiences.

Compliance and Standards

As a registered Microsoft cloud service partner, Deliverability.gg operates within Microsoft’s ecosystem governance and technical standards. However, specific compliance certifications (SOC 2, GDPR, CCPA attestations) and security audit reports are not publicly available. Organizations with regulatory or contractual compliance requirements should confirm certification status directly with the vendor.

Support and Expertise

Support availability, response time commitments, and the composition of the deliverability team are not detailed on the public website. The service’s positioning emphasizes infrastructure provisioning speed and cost efficiency rather than consultative deliverability strategy or ongoing campaign optimization, suggesting a more transactional engagement model compared to full-service managed infrastructure providers.

Pricing & Engagement Models

Deliverability.gg advertises “distributor-level pricing with no middleman markups” and “no hidden fees,” but does not publish specific per-mailbox costs, volume tiers, or minimum commitments. Prospective customers must contact the sales team to receive custom pricing based on sending requirements and mailbox volumes.

The distributor pricing claim suggests cost structures below typical Microsoft 365 Business or Google Workspace list prices, positioning the service as a cost-reduction alternative for high-volume outbound teams. However, without published pricing grids or transparent tier structures, operators cannot perform apples-to-apples comparisons against other inbox providers during initial evaluation.

Setup fees, if any, are not disclosed. The 24-hour provisioning timeline suggests a streamlined onboarding process with limited manual service engagement, which may translate to lower or zero setup charges compared to fully managed infrastructure providers that include strategic consulting and custom configuration.

Engagement models—whether month-to-month, annual contracts, or volume-based commitments—are unknown and require direct sales discussion. Teams should clarify contract terms, cancellation policies, and any volume ramp commitments before committing to the platform.

SLA commitments for uptime, inbox availability, and support response times are not publicly documented. Enterprise teams requiring contractual performance guarantees should negotiate these terms explicitly during the procurement process.

Best Fit For

Deliverability.gg is designed for outbound-focused revenue teams that prioritize Microsoft/Outlook infrastructure alignment and rapid provisioning over consultative deliverability strategy. The platform is particularly relevant for:

  • High-volume cold email operators seeking cost-efficient alternatives to Microsoft 365 or Google Workspace without sacrificing sender reputation quality
  • Teams targeting enterprise audiences where Outlook/Microsoft 365 is the dominant recipient platform and sender reputation with Microsoft infrastructure provides material deliverability advantage
  • Operators requiring fast scaling who need to provision 50+ mailboxes within 24–48 hours to replace flagged domains or launch new campaigns
  • Cost-conscious agencies managing multiple client campaigns where distributor pricing reduces per-client infrastructure overhead
  • Technical teams comfortable with transactional infrastructure providers who can integrate mailboxes into existing workflows without extensive onboarding support

Deliverability.gg may be less suitable for organizations requiring:

  • Transparent upfront pricing for budgeting and procurement without sales engagement
  • Documented case studies and independent reviews to validate performance claims before commitment
  • Consultative deliverability partnerships with proactive strategy, content review, and ongoing optimization beyond infrastructure provisioning
  • Contractual SLA guarantees for uptime, inbox placement, and support response metrics
  • Compliance attestations (SOC 2, HIPAA, ISO certifications) for regulated industries

Onboarding & Operations

The onboarding process follows a streamlined three-step workflow designed for rapid deployment:

  1. Share sending requirements and domain details: Customers provide planned sending volumes, target audiences, and domain information to the Deliverability.gg team.
  2. Outlook inbox provisioning and authentication setup: The platform allocates Outlook-based mailboxes through its Microsoft partnership, configures SPF, DKIM, and DMARC records, and provides SMTP credentials ready for integration.
  3. Load credentials into sending tool and begin warmup: Operators integrate mailbox credentials into their cold email sequencer or sales engagement platform and initiate warmup sequences the next business day.

Timeline: Inbox capacity is available within 24 hours after domain verification and admin approval, assuming domains pass Microsoft’s authentication and reputation checks. This rapid provisioning supports urgent scaling needs or domain replacement scenarios.

Integration: The platform provides standard SMTP credentials compatible with major cold email tools (Instantly, Smartlead, Lemlist, etc.) and sales engagement platforms. API access, webhook capabilities, or custom integration support are not documented and likely require direct inquiry.

Operational playbooks: Details on recommended warmup schedules, sending volume ramp curves, list hygiene protocols, and ongoing domain health monitoring are not publicly available. Teams should clarify whether Deliverability.gg provides prescriptive operational guidance or if customers are expected to manage campaign strategy independently.

Ongoing collaboration: The nature of the customer relationship—whether transactional (infrastructure provisioning only) or consultative (ongoing deliverability strategy and optimization)—is unclear. Operators should establish expectations around proactive monitoring, performance reporting, and strategic advisory during the sales process.
