In the preview mode it is entirely too easy to activate the "send email blast" by mistake.  Today I was trying to copy a sentence in the preview mode and it just emailed instead.  I didn't even have my curser on the button.  If Google can give me a popup asking me to confirm if I want to send an email without a subject line, can't Nationbuilder come up with a popup requiring confirmation that I want an email to blast to 20,000 records? Really, seems like an important, professional element to add. Thanks. Linda
