Does anyone have suggestions for cleaning a list of email addresses? I ask, because I can read into R data on registered voters that includes an "email address" field. I wondered if anyone had experience doing such, especially in R. (I found an article on "How to Clean Large Email Contact Lists for Email Marketing Campaigns"; "www.wikihow.com/Clean-Large-Email-Contact-Lists-for-Email-Marketing-Campaigns". Before I went further with this, I felt a need to ask. Thanks, Spencer Graves
