Disable email notification to lead owner when mass updating

Disable email notification to lead owner when mass updating

Hi All,

I'm the super admin of my zoho account and this week we changed our "lead status" list options. Yesterday I update all leads in our database (15,000) where "lead status is empty" to "not assigned" using the mass update feature selecting 500 records each time.
Because of that, the owners of the leads received TONS of emails.

How do I disables sending email when doing mass update? As Admin, I don't to send emails to the lead owners when doing mass updates.

Thank you

Daniel
