KPI Merge Tags are figures calculated with a formula that you insert into automated emails or landings, for example to turn a donation amount into "meals donated". You create them in the campaign's KPI Merge Tag tab. Labels are shown as they appear in the Spanish version of the console.

  • KPI Transaccional (Transactional KPI): for automated emails (Interacciones > Autoresponders). It calculates with the Monto (Amount) of the donation that triggers the email.
  • KPI Global: for landings. It calculates with the campaign's Total Recaudado (Total raised) and Cantidad de Donantes (Number of donors).

Step by step

  1. Open the tab. In the campaign, KPI Merge Tag, section KPI Transaccional (or KPI Global), and click "Agregar KPI Merge Tag" (or "Agregar KPI global").
  2. Name it. Type Nombre del KPI (KPI name); Variable generada (Generated variable) shows the tag. For a Global KPI, use only unaccented letters, numbers and spaces.
  3. Build the formula in Constructor de FĂłrmula (Formula builder), alternating "Agregar Variable" (Add variable) and "Agregar Operador" (Add operator). "Agregar Variable Multiplicador" creates a constant. The formula must end with a variable.
  4. Click "Crear" (Create).
  5. Use the tag. In an automated email: {{kpi_88_comidas_donadas}}. In a landing, in square brackets: [global_kpi_88_comidas_donadas] (88 is the campaign ID).

Frequently asked questions

In what order is the formula calculated?

In a Transactional KPI, multiplication and division go first. In a Global KPI, operations are applied left to right.

Can I delete a KPI Merge Tag?

No. You can edit it, but there is no button to delete it.
