The Cold Email Infrastructure System Behind 15,000+ Mailboxes [99%+ Inbox Rate]
If your cold emails are landing in spam - especially on Outlook and Microsoft domains - you’re not alone.
Cold Email deliverability (Microsoft, especially) is the #1 silent killer of modern outbound campaigns.
At GrowthBand, we manage infrastructure for 15,000+ cold email mailboxes across B2B teams, agencies, and founders - and consistently maintain a 99%+ inbox placement rate.
In this exclusive live session, I’ll walk you through the exact systems we use to:
✅ Set up bulletproof cold email infrastructure
✅ Monitor inbox placement & blacklist risks in real-time
✅ Fix deliverability issues fast
✅ Rotate and scale mailboxes across providers (Google, Outlook, SMTP)

I’ve been deep in this space for years - I was an early team member at Lemlist, and helped launch Lemwarm, the first cold email warm-up solution on the market.
Now at GrowthBand, we fully manage cold email infra for B2B teams with 99%+ inbox rates.
And I'm ready to share our systems.
