Content
A prototype tool for previewing how HTML email renders across different email clients before anything is sent, because rendering bugs otherwise surface only in a recipient’s inbox.
Problem
HTML email renders differently across clients, and rendering errors usually surface only after sending.
Limitations
Prototype-stage: client coverage was limited to the clients that mattered for the campaigns at hand.
Next steps
A production version would need broader client coverage and automated diffing between renders.
Outcome
Working prototype that surfaced client-specific rendering differences pre-send; deliberately kept at prototype stage.
