Email warmup tool that improves inbox placement in days

New domains need gradual sending volume before cold outreach. LeadSnipper's email warmup tool ramps daily sends, mirrors human patterns, and pauses automatically when domain health drops.

Sending cold email from a cold domain guarantees spam folder

Mailbox providers flag domains that suddenly start blasting unsolicited email. Without warmup, even perfect copy lands in spam. Most teams skip warmup or use shared warmup pools that don't build reputation on their own domain.
