Two places tell you what your automations are eating in credits. The per-workflow status page shows you exactly how many sends each automation has fired in a given period, and the account-wide Historique view aggregates across all workflows. Combine that with your standard credit balance display, and you have a full read on consumption without leaving the dashboard.
Per-workflow consumption
Open Mes Automatisations, click a workflow, and the status page shows the count of contacts that went through, the count of sends per step, plus errors with their reason. Multiply the send count by your credit rate to get the workflow’s monthly cost; only the SendMail and SendSms steps consume credits, everything else is free.
Account-wide view
The Historique page at /Automation/History aggregates fires across every workflow over time. Use it to see which automations consume the most volume, and which sit mostly idle. Combined with the date range filter, this is your monthly review tool.
Export for billing
If you need the data in a spreadsheet for monthly reporting or attribution, you can export statistics the same way as for newsletters. Each row carries the workflow, the action, the contact and the timestamp.
Keep an eye on automation consumption
Open the automated email statistics, set up automatic credit recharge if your volume is variable, and review email pricing for rates.
