how do i contact a lead?
Their email is usually part of the contact information that you get from IDEA. At least it always has been for contacts that I have gotten. Then I email them through my business email. A few have been phishing emails, so beware. I never open any attachments from contacts that I haven’t met in person. And even then, I try to keep all information either in the body of emails or on paper when it comes to people I just met.
