Using variables and fallbacks in campaign copy

How variables resolve, what happens when data is missing, and the unresolved report.

Updated Sep 10, 2026 1 min read

Variables pull values from the lead record. A variable only resolves if the matching field exists on that lead.

Fallbacks

Write a fallback so a missing field never breaks a sentence. Without one, an empty field produces an awkward gap in the copy.

The unresolved variable report

The campaign preview lists every variable that will not resolve for the sampled leads, so you can fix the data or the copy before launching rather than after.

Test sends

A test send goes out through the same sending infrastructure as production and reports the real result, so you see what a recipient sees.

Common problems

  • Blank name in the greeting — the lead has no first name and the variable has no fallback.
  • Variable printed literally — the field name does not match a field on the lead record.
