A simple explanation of the three records that protect your brand and keep messages out of spam.
Why this matters
Business Email is not just a technical choice. It affects trust, cost, response time, and how quickly a team can recover when something goes wrong. This guide is written for teams that send invoices, onboarding, or marketing email.
Practical workflow
•Authorize senders with SPF.
•Sign outgoing mail with DKIM.
•Use DMARC reports to find spoofing and misconfiguration.
What to measure
•inbox placement
•SPF status
•DKIM status
•DMARC policy
Production checklist
•Assign an owner before launch.
•Keep the setup simple enough that another operator can understand it.
•Document the domain, service, credentials owner, backup location, and alert path.
•Review the numbers after real traffic arrives instead of guessing forever.

•Publish a short internal note after each change so support, billing, and delivery stay aligned.
Frequently asked questions
Is this only for technical teams?
No. The goal is to give founders, operators, and developers the same clear operating model, even when the implementation is handled by NexusAI.
Should I automate this immediately?
Automate repeatable checks first, then keep human review for billing, security, customer-impacting changes, and anything that can create downtime.
What should I do next?
Start with one measurable improvement this week. If you need help turning it into a managed workflow, book an infrastructure audit.
