Merge variables
Placeholders like {firstName} and {company} that a sequencer fills per recipient. The technology behind 'Hi {firstName}, I saw {company} is growing!': and behind most of what gets reported as slop.
LinkedBoost supports a defined set of template variables, including declared custom values. Unknown variables are rejected, and a known variable missing for a person blocks their enrollment rather than sending blank copy. Preview rendered messages and resolve gaps before treating a sequence as ready.
In practice
Preview each recipient's rendered message before enrollment, especially any custom research variable used in the opener.
What to check
LinkedBoost validates supported variables and blocks enrollment for a known variable with no value. A variable from another sequencer may use an unsupported name or syntax.
