Map Emails to Domain Type
This breaks down a list of emails into - free mailbox, school domain, sanctioned, malformed, domain doesn't exist, and work domain.
Est run time: 10-60s, depending on rows.
Usefulness: In B2B marketing, free domains are worth close to zero. Sometimes even less than zero because there's an opportunity cost of dealing with low-value leads. This widget could be useful for proactively excluding those leads from scoring / routing / etc. It also auto-remvoes any emails without valid construction.
Caveats: Free = Gmail, Yahoo, etc. School = likely to be a student. Does not do email-level verification. Also, no classification is 100% perfect, but it should be at least 96.54% perfect (at least according to our intern Steve, who studied AI in college).
