The Fear: Breaking Your Mission-Critical M365/Google Setup
For any IT Manager, the idea of adding 500 seasonal workers to the main corporate email tenant is a nightmare.
- Risk of Downtime: One wrong config change could stop the CEO from receiving emails.
- Reputation Damage: If a temporary worker gets phished or sends spam, your main domain's IP reputation suffers, affecting everyone.
The SmtpMan Promise: We do not touch your root domain. Not a single byte.
Zero-Touch Promise
Your existing Exchange/Gmail setup remains 100% untouched. No connectors to install. No plugins to deploy.
The Solution: The "Parallel Highway" Architecture
We use the "Auxiliary Domain" (Subdomain) standard to create a completely separate infrastructure.

Why "Subdomain Isolation" is Safer
By using a subdomain (like @team.brand.com), you create a firewall around your
reputation.
Reputation Firewall
Even if your frontline team generates thousands of system alerts or emails, your main domain's sending reputation remains pristine. They have completely separate sender scores.
Configuration Safety
SmtpMan has its own SPF, DKIM, and DMARC records tailored for the subdomain. You never have to mess with the delicate DNS records of your root domain.
Implementation: Just One DNS Record
Zero Migration. Zero Downtime.
Because SmtpMan is an "Add-on", not a replacement, there is no data to migrate. Your existing M365 users won't even know it exists.
