Cold email 101
Cold email infrastructure sounds complicated — it isn't. You need four things, and our app gives you all of them in a few clicks.
You never send cold email from your main domain — you buy lookalike domains to protect it. .com domains get the best deliverability, and ours are just $9.
Each domain hosts 2–3 sending inboxes. Google Workspace and Microsoft 365 inboxes land in the primary tab — and ours cost $3 instead of $6–$7.20.
New inboxes need 2–3 weeks of "warmup" before they can send safely. Or grab our pre-warmed inboxes and start sending the day you order.
Connect your inboxes to Instantly or Smartlead and launch campaigns. We're certified by both, so everything plugs in seamlessly.
Most agencies run 30–300 inboxes. Drag the slider to see what switching to Upscale B2B saves you every single month on Google Workspace inboxes alone.
