Trusted infrastructure, built for scale
Connect, engage, earn. That's the whole loop.
Sign in to your email account. Your Gmail joins the deliverability network. We never see your password — just an OAuth token you can revoke anytime from your account settings.
Your inbox engages with other participants on autopilot — replies, opens, label organization, spam-folder rescues, important-flag corrections. Every action improves your sender reputation.
Earnings accrue in real time on your dashboard. Hit the minimum threshold, request a payout to your wallet. No lockups, no waiting periods.
No credit card. No subscription. Revoke anytime. Read our Privacy Policy.
Your inbox quality score — based on account age, engagement history, and activity patterns — determines your tier. Most established Gmail accounts start at Silver or Gold.
New or low-activity inboxes. Solid starting point — most accounts level up within 30 days of activity.
Established inboxes with consistent activity. Where most accounts land on day one.
High-reputation inboxes with strong engagement history. Significantly higher earning rate.
Elite inboxes. Maximum capacity, maximum rewards. Usually aged accounts with years of activity.
Scores are recalculated daily. Quality improves organically as your inbox stays active on the network.
Connected my Gmail account and genuinely forgot about it. Got a reward notification two weeks later. Setup took maybe 3 minutes total.
I manage email for multiple clients so inbox health is critical for me. Cheddar gives me visibility into deliverability metrics I couldn't get anywhere else.
Referred my whole team. Once a few of them got connected, the 10% lifetime cut started showing up in my wallet on schedule. Set-and-forget income.
Share your link. Every reward your referrals earn from participating, you earn 10% on top — paid on schedule, forever.
One tier. No expiration. No fine print.
Sign in to grab your link. Share it anywhere. Earn forever.
Not a toy project. Not a browser extension that scrapes data. Purpose-built infrastructure for email network economics.
Every data point comes from genuine email interactions between real accounts. Opens, replies, thread depth — all measurable, all real. No synthetic benchmarks or simulated traffic.
Six dimensions: account age, message volume, geographic diversity, provider reputation, activity consistency, and network history. Your score isn't static — it improves as your inbox stays active. Most accounts see score increases within 2-3 weeks.
Real inboxes across 40+ countries contributing to email health data. The geographic diversity provides broad coverage for inbox quality monitoring and deliverability insights.
Rewards are tracked in real time on your dashboard. Withdraw anytime once you hit the minimum threshold. No lock-ups, no complicated mechanics. You earn rewards, you receive rewards.
