The Concept of "Domain Age"
In the world of email deliverability, trust is not given; it is earned over time. When you register a new domain (e.g., get-company.com), it is born with Zero Reputation.
To an Email Service Provider (ESP) like Gmail or Outlook, a brand-new domain sending 50 emails a day behaves exactly like a "Spam Burner Domain" used by bad actors. Consequently, ESPs place new domains in a "Sandbox"—a probationary period where deliverability is throttled, and scrutiny is high.
The "14-Day Rule" At SendScale, we enforce a strict recommendation: Do not send cold outreach from a domain less than 14 days old.
Days 1-14: The domain should be in "Warmup Only" mode.
Day 15+: You may begin "Ramping Up" cold outreach volume slowly.
The Reputation Hierarchy
Your ability to land in the Primary Inbox is determined by three layers of reputation:
IP Reputation: The trust score of the server sending the mail. (SendScale handles this for you via our sending partners).
Domain Reputation: The trust score of your specific URL (e.g., sendscale.com). If you spam, this score drops, and all accounts on this domain suffer.
Mailbox Reputation: The trust score of the specific user (e.g., tom@).
How SendScale Manages Age
When you purchase a domain or connect a fresh one, SendScale’s Warmup Engine immediately begins the aging process.
Interaction: We don't just let the domain sit idle. We send traffic through it.
Consistency: The engine sends emails daily, proving to Google that this domain is active, stable, and human-owned.
Strategy for New Domains:
Purchase Domain.
Enable Warmup immediately (Settings: 30/day limit, Ramp-up 1/day).
Wait. Do not launch a campaign. Use this time to build your lead lists in SmartSearch.
Launch on Day 15. Start your campaign with a low volume (e.g., 10-20 emails/day) and increase weekly.
