I’m trying to test ad server with Brevo (in order to insert e-mail ads) and the service is asking for EUID (email user unique ID).
Where can I find Brevo email user unique ID?
Some EUID examples from other providers:
ACTIVECAMPAIGN
%SUBSCRIBERID%%MESSAGEID%
HUBSPOT
{{contact.firstname}}{{contact.hs_object_id}}
MAILCHIMP
|CAMPAIGN_UID|-|UNIQID|
PARDOT
{{Recipient.ID}}{{Current_Day}}{{Current_Month}}{{Current_Year}}
