Global inbox placement sits around 84%, with Outlook at 75.6%. So roughly 1 in 6 of your emails dies in spam or vanishes before anyone reads it, and you keep blaming your copy. The Inbox Insurance Kit is the exact setup that gets you in front of real people: authentication, domains, and a day-by-day warmup table you can copy straight into your sender.

See how we run cold outreach with you →This isn't a lecture on "best practices." It's the setup checklist in the order that actually moves inbox placement, starting with the one piece that does the most and now decides whether Gmail even accepts your mail.
Full SPF, DKIM, and DMARC hits 83.75% inbox placement versus 44.99% with none. That's roughly 2.7x more likely to land. It's also mandatory now: from November 2025 Gmail moved from delaying non-compliant bulk mail to flat-out rejecting it.
One bad week can burn the domain your invoices and client work run on. The Kit shows you how to buy secondary lookalike domains the right way: no hyphens, no numbers, aged where you can, isolated off the mothership so a burn never touches your real business.
Handed over literally. Week 1: 5-20 a day. Week 2: 10-40. Week 3: 20-60. Week 4: 25-80, then hold. Never raise volume more than 20% in a day, never send before authentication is live, and give it 2-4 weeks minimum before you scale.
The safe cold cap is 25-50 emails per inbox per day, not the 2,000-a-day technical limit Google quotes. Run 3-5 inboxes per domain. So 200 sends a day means roughly 8 mailboxes spread across 2-3 domains. The Kit does the math for your target volume.
Keep complaints under 0.1%, bounces under 2%, and honor one-click unsubscribe within 2 days. Cross any of these and providers throttle you fast. This is the daily checklist that tells you when to slow down before the damage is done.
The trigger-words and formatting that still hurt you, with the honest caveat: filters weigh your reputation, authentication, and engagement far more than keywords. Necessary, but it will never save a domain that's already cooked.
The baseline cold-email reply rate is about 3.43%, and the top 10% of senders hit 8-12%. When you're stuck well under that, rewriting your subject line for the tenth time won't fix it. Your mail isn't getting read because it isn't getting delivered. Fix delivery first, then your copy finally gets a chance to do its job.
"I scaled to 500 sends a day off my primary domain and torched it in a week. Suddenly my client work was landing in spam too. I wish I'd had this exact setup before I sent a single email. The warmup table alone would've saved me three months of cleanup."
Authentication, secondary domains, the warmup table, the send-math, and the daily rules that keep you out of spam. Free, instant, yours to keep.

No. It's the specific cold-outreach setup for agency owners: secondary domains over your primary, the 25-50 per inbox per day cold cap instead of the 2,000 technical limit, and a literal warmup schedule. Every number in it carries its source so you can trust it.
This Kit is built to stop you burning a domain, not to revive a dead one. Recovery typically takes months and isn't guaranteed, so the honest move is to isolate the burn, set up clean secondary domains the right way, and never repeat the mistake. The Kit walks you through exactly that.
Completely. We give away the setup on purpose. Once you see how precise it is, you'll understand why agencies have us run the whole client-acquisition machine for them instead of piecing it together alone.
The Kit gets you into the inbox. But landing in the inbox is one link in the chain: you still need a tight list, calls that show, and a close that sticks. AgencyGod installs the whole machine with you, deliverability included, so you're not learning DMARC at midnight while your pipeline sits empty. We put $10,000 on the line. You either get the result or you get paid.
