Conducting outbound prospecting from a core corporate domain introduces catastrophic deliverability risks to internal business communications. Isolating outreach across secondary domains preserves brand integrity.
1. Outbound Infrastructure Best Practices
- Secondary TLD Deployment: Acquire separate domain extensions (`mailcampaign-app.com`, `trymailcampaign.com`) with 301 redirects to the primary brand.
- Strict Volume Constraints: Limit individual Google Workspace or Outlook mailboxes to a maximum of 30–50 cold emails per day.
- Ramp-Up Periods: Warm newly provisioned inboxes for a minimum of 21 days before initiating outbound prospecting.
