The "Sandbox" Period
When you register a new domain (e.g., get-sample.com), Google and Microsoft place it in a "Sandbox." They do not trust it yet. If you start sending 50 cold emails a day immediately, you will be flagged as a spammer and your domain reputation will be ruined permanently.
The 14-Day Protocol
We strongly recommend a 14-Day Warmup Period for all new domains.
Days 1-14:
Warmup: Enabled (Fire).
Campaigns: PAUSED. Do not send any manual emails.
Goal: Let the automated engine send/receive emails to build a history of positive engagement (opens, replies, "mark as important").
Day 15:
Action: You launch your first campaign.
Volume: Start low (e.g., 20 emails/day) and ramp up.
Can I skip this?
Technically, yes. But the risk of landing in spam is high.
Exception: If you buy Pre-Warmed Accounts (sometimes available via premium vendors), they may be ready sooner. But for standard new domains, 14 days is the industry standard for safety.
