We are sending email communication to the customers already present in 'All Subscribers'. We intend to use the same Subscriber Key but may send to different email address. The requirement is that the Email address in 'All Subscribers' for that subscriber should not be updated. We are sending via Journey Builder. Is there any work around for this? enter image description here

When configuring your Email Send activity in JB, you can select the expected behaviour in context of All Subscribers list. This option is however only available in the recently introduced Transactional Journeys: enter image description here

You do it in Activity Summary > Delivery Options. Once you set it to "Only add new subscribers", then the email address connected to an existing Subscriber Key will not be updated.

Unfortunately, in the regular journeys, this setting is not available, and it is not possible to avoid updating All Subscribers in regular journeys.

  • So the email will be sent to email in the DE, if it's not the one linked to the sub_key in all sub? Commented Oct 21, 2020 at 10:22
  • Yes, @nandhiniramchandran - that’s the advantage of sending it from JB Commented Oct 21, 2020 at 10:22
  • But I don't find that option in my account Commented Oct 21, 2020 at 21:12
  • @nandhiniramchandran - please update your question with more details, supported with screenshots of your email activity configuration Commented Oct 21, 2020 at 21:31
  • I have added the screenshot, this is my problem I already have the Sub_key linked to different email address in all sub. For this email send, i need to use different email with same sub_key as that in all sub but it should not be updated in all sub. Commented Oct 21, 2020 at 22:05
