Disabling the welcome mail is possible with an extra parameter in the Set-UnifiedGroup cmdlet in Exchange PowerShell: -UnifiedGroupWelcomeMessageEnabled:$false. See https://docs.microsoft.com/en-us/powershell/module/exchange/users-and-groups/set-unifiedgroup
Use this as a part of a custom group creation flow if you would like to restrict and/or customize the welcome mail for many groups across your tenant.

Have to agree I was hoping to create a list in the group and then once all there send an email with carefully drafted text saying why they are a member. I was then going to use that list as a means of granting the whole list, en-bloc, access to a sharepoint site. There are several problems. First creating the list one by one from the corporate address book is tedious. However, I can't find a way to import a list as a separate address book as the addresses in the list are already in the corporate address book. I tried simply copy pasting the list into the new members dialogue, which looked hopeful, but that seemed to work only 10 or so addresses at a time - and those added were immediately sent an email - I don't want that. Actually this was easier in the old world of file shares. I ran a mail merge to email and provided a folder link. Now, one way or another I have to manually add a long list of names either to create an outlook group, or if I don't go that route, to give access one at a time to all the people who need access to the sharepoint folder where the goodies we're trying to give them will be.
