Can I please ask what do you mean by a "place holder" in the subject line? I run into this problem a lot and it courses issues as I have alerts being copied into a CRM (the CRM # field is included in the notification) if there are multiple notifications in one email this does not work.
Keen to see how best I can trigger the emails one at a time. And I agree, it needs to be fixed or at least an option to either select group notification or send out singular
Thanks in advance
