If you’re selling high-ticket B2B and want a repeatable way to generate demos without spending 10+ hours a week doing manual outreach - this is your playbook.
This system automates 1,000+ emails per day with 50%+ open rates and up to 5% reply rates. It takes 1–2 hours to set up, runs quietly in the background, and is easy to hand off once live. You can start without personalization, but layering in custom first lines will give you even stronger results.

Step-by-Step Setup
1. Domain and Email Infrastructure
To protect your primary domain, we use secondary domains exclusively for outbound. Each domain supports 3–5 inboxes. Each inbox sends 30–50 emails/day max to avoid spam triggers.
Choose domains similar to your primary brand. Examples for 1752.vc:
Stick with .com where possible. Avoid low-reputation extensions.
Set up your account at workspace.google.com. You can add 3 domains per workspace, and 3–5 inboxes per domain.
For each sending domain, configure:
Redirect each secondary domain to your main site. GoDaddy forwarding guide here.
Forward all replies to one “monitoring inbox” using Gmail forwarding, or use Instantly’s Unibox feature to centralize replies.
2. Warm-Up Protocol
Before any campaign starts, you must warm up every inbox. In Instantly, click the flame icon next to each email account to enable warm-up.
Suggested daily limits:
Warm up for 14 days minimum. Always keep warm-up running in the background.
3. Lead Sourcing & Verification
