Turning off notifications when importing users and messages


Can you give me a quick hint as to all of the notifications that I should turn off prior to importing thousands of messages and members? (via the rest API)

I'd like to be able to get this all set up quietly (without spamming everyone with thousands of notifications as I run the import). Once I have everything setup correctly I'll send an email to all the members, but I don't want them emailed every time I insert a new message, or welcome messages sent as each member is inserted.
