Check a cold email's merge tags
Paste a cold email and your CSV header. Flag tags with no matching column, unbalanced braces, broken spintax and tags that will print blank. It runs in your browser; nothing is uploaded. Free, no account.
Both boxes start with an example: a made-up email and the 67Leads export header. Replace them with yours. Nothing is uploaded; the check runs in your browser.
What it checks
- Tags with no column: {{first_name}} when your header says "First Name" or has no first name at all. It suggests the closest column. Tags your sending tool fills in itself, such as a sender name, will show up too; ignore those.
- Tag spelling: a tag that matches a column only when case, spaces or underscores are ignored. Some tools match the header exactly, so write the tag the way the column is written.
- Unbalanced braces: a "{{" with no "}}", a stray "}", and braces inside braces, with the line they are on.
- Spintax: {a|b|c} blocks with an empty option or only one real option. Nested spintax is flagged as nested braces; many tools do not support it.
- Empty-value risk: tags with no fallback. If you paste some rows under the header it counts the rows where that column is empty, so you can see how many emails would print "Hi ,".
- Single-brace tags: {first_name} with one pair of braces and no | is not spintax. Some tools expect double braces and send it as text, so it is flagged.
Fallbacks
Many sequencers let you write a fallback after a bar, as in {{first_name|there}}, which is used when the cell is empty. Syntax differs between tools, so check your tool's documentation. A fallback does not fix a bad list: a list with many empty first names needs cleaning first (see the lead list cleaner).
Privacy
Nothing is uploaded or stored. The page sends no request with your email or your list; everything is worked out in your browser.
What it does not do
- It does not know your sending tool's syntax. It reads {{double}} braces as tags, {single|bar} as spintax and other single braces as possible tags.
- It does not check that the email is any good. For that see the cold email grader and the spam word checker.

Questions
Paste your email and your CSV header above. Each tag is compared with your columns, and the ones with no match are flagged.
Some tools match the header exactly, with its case and spaces. The checker flags a tag that matches only when those are ignored, so you can spell them the same.
A value written after a bar, like {{first_name|there}}, that is used when the cell is empty. Not every tool supports it, so check yours.
No. The check runs in your browser; nothing is uploaded or stored.
It flags {a|b} blocks with an empty or single option, and braces that are nested or unbalanced. It does not know which tool you will send with.
