How effective and secure is sending user information to facebook in pixel? -


i want re-target users based on purchase on website. example, if purchases kids wear website, want re target user, when launch offer in kids wear range.

i read this article. looks effective can send customers mobile/email , purchase category i.e. kids-wear facebook. later, can re-target these these users on facebook if have offer in kids wear.

but worried few things:

  1. is correct share customer mobile/email facebook. legal consequences of this?
  2. should send both email/mobile? if user uses same mobile different email facebook or vice-versa?

if can share case study of using mobile/email in campaigns, great.

arrays - What causes a java.lang.ArrayIndexOutOfBoundsException and how do I prevent it? -
