Executing outbound B2B sales development outreach without risking the corporate domain's Google Workspace reputation requires dedicated secondary infrastructure.
1. Outbound Infrastructure Architecture
| Layer | Configuration Standard | Reputation Defense Role |
|---|---|---|
| Domain Architecture | Secondary variations (e.g., getemailcampaigner.com) | Protects primary root domain from spam flag pollution |
| Sending Inboxes | Max 3 inboxes per secondary domain | Limits per-domain sending velocity |
| Daily Inbox Cap | Max 30–50 outbound emails / day / inbox | Avoids volume-based heuristic flags |
| Spam Protection | Automated peer-to-peer warmup network | Maintains continuous positive engagement baseline |
