Rewards accumulate in real time on your dashboard. Hit the payout threshold and withdraw anytime. No lock-ups, no minimums that take months to reach.
No credit card. No subscription. Revoke access 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. The referral rewards alone are meaningful at this point. The multi-tier structure really adds up.
Share your link. When your referrals participate, you earn bonus rewards — up to 5 tiers deep. The network grows. So do your rewards.
Percentages represent your share of each tier's rewards
Your referral link appears in your dashboard after signup.
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.
