I ran into issue when I used zapier to parse emails into LionDesk. Lion Desk sent a confirmation email of the new lead. That got forwarded to zapier and it looped 1000 times. Maxed out my zapier membership.
Allow notifications of new lead creation to go into an email account that I can specify. This way I can keep a gmail account only for leads and not mix it up with real estate transaction contract work. It would also avoid the zapier death spiral.
