    Merge Variable Linter

    Example session with this skill installed

    Check my sequence copy against these fields: First_Name, Company, Job_Title. Copy: Hi {{first_name}}, how is life at {{Company}}? Sample: John, Acme, CEO.

    • Read your context and instructions
    • Compiled the merge variable linter
    • {{first_name}}: MISS (Case mismatch with First_Name).
    • {{Company}}: MATCH.
    • Job_Title: UNUSED.

    Verdict: NO GO. Fix case sensitivity on {{first_name}} to match First_Name. Render: 'Hi , how is life at Acme?' (Grammar broken by missing value).

    Connects securely to your tools. The creator never sees your data.

    About this skill

    Check that every merge variable in a sequence resolves against the fields actually present on the rows, before the campaign sends. Use when someone is about to launch, has seen blank gaps in a sent email, or wants their personalization tokens verified.

    Every free skill sits on a 30 day review cycle. Fixes and improvements ship as repo updates. Free forever. The premium version of this workflow lives in the Cold Email System Pack at mambabuilt.com.
