Technology Under the Hood

99.4% Inbox Placement (Measured Q1 2026)

Our peer-to-peer warmup model delivered 79,996 emails to inbox vs just 519 to spam across all active warmup mailboxes in Q1 2026. Methodology: inbox vs spam folder detection via IMAP monitoring across our warmup network.

50 Million+ Unique Variations

200 sender names x 150 company references x 30 business topics x spintax template multipliers = 50M+ unique combinations. Each warmup email uses a different variation so spam filters cannot detect repetitive patterns.

Deep Conversation Threading (115K+ Threads)

Warmup emails trigger multi-turn conversations — up to 5 replies deep. 115,000+ conversation threads generated since platform launch. Gmail and Outlook see real engagement signals, not one-off messages.

Near-Zero LinkedIn Restrictions

Near-zero restriction rates across connected accounts (as of March 2026). Our 4-week ramp system and conservative daily limits (50 invites, 150 messages) keep your profile safe.

4-Week LinkedIn Warmup (Gradual Ramp)

New accounts start at 10 invites/day and gradually increase over 4 weeks. Accounts with restrictions use an 8-week recovery ramp.

Dedicated Proxy Routing (40+ Countries)

Every LinkedIn account gets its own fixed proxy located near your real IP — covering 40+ countries. No shared IPs, no fingerprint overlap. Bring your own proxy or use ours.

Automatic Peer Protection

Mailboxes with >15% spam rate are automatically excluded from the warmup pool. Your reputation is protected from contaminated senders.
