Cold Email Ops Arcade
Playable · Browser · Installs offlineProspects walk toward your competitor. You stop them with domains, inboxes, and warmup before they get there. Quota pressure, bounce risk, and a certification track that gates upgrades behind real questions about SPF, DKIM, and the Gmail bulk sender rules.
Built for people who live in deliverability. If you have ever bought a domain at 11pm because the last one got cooked, it will feel familiar.
