Why should I choose Immutable over Keymailer?

Immutable follows the player a creator produced: whether they signed up, completed quests or bought, and whether you can message them again before and after launch. Creator-sourced players join the same owned audience that Immutable's lifecycle email converts, which lifted Empulse's wishlist-to-purchase conversion 2.2x.

How does Immutable compare to Keymailer for creator campaign measurement?

Immutable Amplify measures each referred player: signup, quest activity and purchase, attributed back to the creator link and scored for quality, with bot signups filtered out. Partnier by Keymailer, the studio-side dashboard since the rebrand, centres on key distribution, press and influencer outreach and paid promotions. Its plan page lists content, traffic, demographic and UTM tracking, with no per-player quality score listed.

What features set Immutable apart from Keymailer?

Three things set Immutable apart: 1. Player-level attribution and quality scoring on every creator link 2. Creator-sourced players folded into one owned audience you can email 3. Compensation models (flat fee, CPA, revenue share, hybrid) paid on bot-filtered players

Does Immutable work with tools I already use?

Yes. Amplify's tracking and attribution work with a studio's own creator relationships through self-serve in Hub, so creators you already work with, however you first reached them, get a tracked link and feed the same player profiles.

What results have studios seen with Immutable?

1047 Games reached 300K+ Steam wishlists for Empulse in under two months, and its owned fans converted to Early Access purchases at 2.2x the rate of other wishlists. The full breakdown is in the 1047 Games case study.

What makes Immutable different

Player-level creator measurement

Each creator gets a unique referral URL. Amplify scores every referred player on engagement, tier progression, secondary referrals and predicted lifetime value, separating paying players from empty signups.^[4]

The tracking covers streamers on Twitch, YouTube Live and Kick, video creators on YouTube, TikTok and Instagram, and community influencers on Discord, Reddit and Twitter.^[4]

One audience from first click to launch day

Creator-referred players land in owned player profiles, the audience used for attribution and lifecycle email. A player sent months before launch stays reachable ahead of Steam's launch-day email.^[4],[6]

Immutable's email flows run from signup to purchase. With them, Empulse's owned fans converted from wishlist to Early Access purchase at 14.0%, against 6.4% for other wishlists.^[5],[6]

Compensation tied to verified players

Amplify pays creators on actual signups and conversions: a flat fee for established creators, CPA per signup, a revenue share of player spend, or base fee plus bonus.^[4]

Because bot detection filters artificial signups first, a CPA or revenue-share payout is calculated on real players, and the payment model and the measurement come from the same system.^[4]
