Hi @morris-minor ,
Thank you for your post.
There isn't a way to turn off those notifications for relisting items. While I understand you already have them by email, the message ones are for reminding sellers of those items.
The Simple Delivery times are also automatically set on the system so there wouldn't be a way to manually change it.
Thank you,
Kat
