Question
Lead ID Keep changing :S
On 09-03 we exportet all our leads from Marketo. We exportet the ID Field and the Email-Field. When we use these ID's to trigger campaings via our website, Marketo sometime says that some ID's dont exist. When we search in marketo on email-adres we find out that the leads suddendly have a different Lead ID.
Does anyone know why this happens en what we can do to stop it.
