On a schedule the scenario pulls fresh contacts from Brevo and pushes them into Zabbix customer lists. Retargeting always runs on a current base.
Automating Brevo and Zabbix takes no code: a ready-made scenario does the routine for you.
You can launch this Brevo + Zabbix integration in Scriptera: describe the task in plain words — the scenario is built, launched and monitored for you.
