Email deliverability for Google Workspace & Microsoft 365 teams · since 2018
We fix
Paste your domain and in 30 seconds you’ll know exactly what’s broken — then we fix it for good, and keep it fixed.
How the inbox is actually decided
Authentication
SPF, DKIM and DMARC can all be published in your DNS and still not align on the mail you actually send. “We have DMARC” means nothing on its own — what counts is whether it passes in the live headers landing at Gmail.
Presence isn’t protection.
The 2024 rules
Since February 2024, Gmail and Yahoo reject bulk mail that isn’t authenticated with SPF, DKIM and DMARC, and they hold your spam-complaint rate under 0.3%. Setups that worked for years quietly started bouncing.
The bar is higher than your last audit.
Reputation
Rewriting subject lines won’t save a domain with no DMARC and a cold IP. Inbox placement is decided by authentication, sending reputation and list hygiene — long before a single word of content is scored.
Fix the plumbing, not the prose.
What we do
We rebuild SPF, DKIM, and DMARC from the ground up. Ramp DMARC from monitor-only to enforcement without losing a single legitimate send. Get off blocklists. Set up BIMI when you're ready. Then keep watching, so it stays fixed.
Shared drives cleaned up. External sharing under control. Super-admin hygiene. Onboarding and offboarding that actually runs. The kind of work you only notice when it stops being a fire.
Google Cloud setups for small teams: Cloud Run, Firestore, only the IAM you need. Gemini, Claude, or open-source models wired into Sheets, Slack, your support inbox. Built to run in production.
Migrations, admin and security hardening, email deliverability, and Gemini rollout. Done right, on schedule, with no surprises.
Gemini Enterprise, AI automations, infrastructure modernization, and on-prem to cloud migrations that keep running after we hand them over.
Selected work
Migration
Moved a professional services team into Google Workspace with staged cutover planning and verified mailbox data.
Outcome: zero mailbox data loss; users back to work Monday 9am.Deliverability
Resolved SPF, DKIM, and DMARC conflicts damaging inbox placement and domain reputation across outbound mail.
Outcome: DMARC p=reject in 6 weeks; bounce rate cut to under 0.5%.Cloud modernization
Refined a cloud deployment into a simpler, observable platform with secure service boundaries and automation-ready structure.
Outcome: release cadence weekly; cost down 40% in one quarter.Google Cloud
Certified Professional Cloud Architects who design, migrate and run Google Cloud for teams that cannot afford a science project. Small footprint, least-privilege access, a bill you can explain.
Enterprise AI
Search and assistants grounded on your own documents, on your tenant, with access controls that hold.
Automation
Document extraction, support-inbox agents and data pipelines wired into the tools your team already uses.
Infrastructure
Cloud Run, GKE and managed databases replacing hand-managed servers, with observability from day one.
Migration
Assessment, landing zone, lift-and-shift or re-platform per workload, and a phased cutover with minimal downtime.
Data
Operational data and SaaS exports modelled in BigQuery and served in Looker Studio, or answered by Gemini in plain language.
Governance
Least-privilege IAM, secure service boundaries, budgets and alerts, and rightsizing reviews that keep the bill small.
The work behind the work
A reply that lands in the inbox is worth more than any dashboard. We read your DNS, your headers, and your Admin logs before we touch a record. DMARC at p=reject is a milestone, not a setting you flip and walk away from. We don't hand over slide decks — we ship the thing, then stay until it holds.
