Done-for-you mailbox infrastructure from the team behind Lead Gen Jay. Domains, DNS, warmup, providers — perfectly configured. Live in under an hour, not three weeks.
Real numbers from 25,000+ deployed mailboxes. We tune SPF, DKIM, DMARC, BIMI, and warm-up cadence to Gmail and Outlook spec — so your team isn't fighting filters in week three.
When mailboxes from Inbox Insiders send to each provider, here's where the messages actually arrive.
No DNS dashboards. No Workspace admin chairs. No “wait, why are we in spam?” Slack threads. Watch the whole flow:

“Before joining, I was struggling with 15-16% open rates and wasting money on incorrectly set up email systems. Now I'm achieving 76% open rates — numbers I never imagined possible.”
“I just wanted to commend the team. The experience was incredibly easy — and all the mailboxes got set up for me.”
“Within about 30-45 days in the program I doubled what I had been making on average for the previous six months. The cold outreach systems are the best I have seen.”
“Before this, I was getting about 30% open rates for my clients. Already I'm getting 50%+ open rates and my client is very happy.”

Average time from order to live mailboxes is 47 minutes. Domains register, DNS propagates, SPF/DKIM/DMARC verify, and a 21-day warmup begins automatically. You'll get a credentials export the moment everything goes green.
Across 25,000+ deployed mailboxes, 30-day rolling inbox placement sits at 99% measured against Glock Apps seed lists across Gmail, Outlook, and Yahoo. Spam folder rate stays under 1%, bounce rate under 0.5%.
No. We register the domains, configure every DNS record, run the warmup, and hand you working credentials. If something drops out of spec later, we fix it — that's what the per-mailbox monthly fee covers.
Yes. Pick 'full control' mode and supply the domains you already own — we'll handle DNS configuration and mailbox provisioning. 'Easy' mode auto-registers fresh .com domains for you ($12 each).
Drop our MCP config into ~/.claude.json and Claude Code (or Cursor, or any MCP client) gets five tools: suggest_domains, check_domains, create_order, get_order_status, export_credentials. Same auth as your dashboard, charges your saved card. Most teams use it for client onboarding agents.
Auto-upload supported for Instantly and EmailBison directly from the order form (or via the MCP server). Standard SMTP/IMAP credentials work with Smartlead, Lemlist, Reply, and any other tool that accepts custom mailbox connections.
Yes — pause or cancel any mailbox monthly. No long-term contracts. Domain registrations are yours and transferable.
Spin up your first 100 mailboxes in under an hour. Or hand the keys to Claude Code and watch it happen.
