Capabilities
The technical systems behind trustworthy email.
Boutique Ink LLC works across email authentication, deliverability, DNS, domain control, and the cloud platforms organizations depend on to send legitimate mail.
The work begins with a defined business or technical problem—not an indiscriminate platform checklist. Each engagement uses only the capabilities needed to identify the cause, make controlled changes, and leave the environment documented and governable.
Email authentication and domain protection
Establish which systems are authorized to use an organization’s domains, correct authentication failures, and move toward enforceable protection without interrupting legitimate mail.
- DMARC policy and reporting analysis
- SPF architecture and lookup-limit remediation
- DKIM configuration, selector management, and alignment
- Third-party sender discovery and classification
- Representative authentication testing
Deliverability and message-path diagnostics
Determine why legitimate email is rejected, deferred, routed incorrectly, or classified as spam.
- Complete message-header and authentication-result analysis
- SMTP routing, relay, connector, and mail-flow review
- Rejection, deferral, and non-delivery investigation
- Microsoft 365 and Google Workspace troubleshooting
- Third-party sending-service remediation
Microsoft 365 and Google Workspace
Configure and troubleshoot the tenant, domain, identity, and mail-flow settings that affect authenticated email.

Cloud applications and third-party senders

Maintain reliable control over the records, providers, and administrative relationships on which email depends.
