What We Actually Do
Email is the most business-critical communication channel most organisations have, yet it's routinely left to chance. Misconfigured SPF records, missing DKIM signatures, and absent DMARC policies leave your domain open to spoofing and your legitimate emails landing in spam.
We implement the full email authentication stack - SPF, DKIM, DMARC, MTA-STS, and BIMI with VMC where applicable - and verify it against all major inbox providers. For organisations that need complete control, we also deploy and manage self-hosted mail infrastructure using Carbonio or Postfix.
Our deliverability work goes beyond records. We analyse your sending reputation, identify blacklistings, and set up ongoing monitoring so problems surface in minutes, not weeks.

Our Process
Every engagement follows a structured methodology - documented before we start, so you always know exactly where things stand.
- 01
Domain & Sender Audit
We enumerate all sending domains, subdomains, and authorised senders (ESPs, CRMs, helpdesks) and audit every DNS record against current best practices.
- 02
Authentication Implementation
We implement or correct SPF, DKIM per selector, and DMARC policy, then validate against major inbox providers before moving to enforcement mode.
- 03
DMARC Ramp
We progress DMARC policy from p=none → p=quarantine → p=reject over a managed timeline, monitoring aggregate reports at each stage to catch legitimate senders before they're blocked.
- 04
BIMI & VMC
For eligible domains, we procure or validate a VMC, configure the BIMI DNS record, and verify logo display in supported clients.
- 05
Monitoring & Handover
We configure DMARC reporting, blacklist monitoring, and deliverability alerting, then hand over with full documentation of your sending infrastructure and a runbook for common scenarios.
