Deduping and metadata enrichment from email

Many people include an email signature in their email addresses and those contain some combination of name, email address, phone number, job title, physical address. That information could be extracted with machine learning and used both for improved contact de-duping and to enrich the metadata of a contact automatically. Of course you’d need to ask permission to access message bodies, but I’d be down to authorize it in return for the upside. Ctd.ai has this working although exposed in a product that is quite different.
