Email Marketing A/B Test Log and Learnings Database
Why This is an Opportunity
The problem isn't running A/B tests — every email platform supports that. The problem is that test results are trapped inside platform dashboards and never become organizational knowledge. When someone asks 'do emoji subject lines work for our audience?' the answer requires digging through months of campaign reports across one or more ESPs. A simple CRUD app solves this: a form to log each test with structured fields (test type, hypothesis, variant A, variant B, winner, metric, lift percentage, sample size, notes), plus a filterable/searchable table view. Over time it becomes an invaluable reference. No integrations needed — manual entry is fine because the value is in the structured, searchable archive.
Key Pain Points
- •Test results are locked inside ESP dashboards and require clicking through individual campaign reports to find
- •Teams re-run tests they've already conducted because nobody remembers or can find the previous results
- •No way to search across all past tests by variable type (e.g., 'show me every subject line test we've run')
- •When an email marketer leaves the company, their accumulated testing knowledge walks out the door with them
- •Stakeholders ask 'what do we know about X' and the answer requires hours of manual campaign archaeology
Original Discovery
Email marketers run A/B tests constantly — subject lines, send times, CTAs, preview text, layout variations — but the results evaporate. They live in platform-specific dashboards (Klaviyo, Mailchimp, HubSpot) and are never aggregated into a searchable knowledge base. Six months later, someone on the team tests the exact same subject line angle because nobody remembered the last result. A dead-simple log where marketers record each test (hypothesis, variants, winner, confidence level, key metric lift) and can search/filter past tests by element type, audience segment, or date range would compound institutional email marketing knowledge over time.
