Tamara Gielen, an expert in email marketing and based in Belgium, asked her Twitter followers to finish the sentence “Email marketing works because…”. The result has been a great list of reasons why email marketing is an important part of the mix for any marketer today.
Here are my fave five:
- @marcmunier: Email marketing works because people spend more time at their inbox than any other online activity
- @djwaldow: “Email Mktg works b/c it has a proven, measurable, ROI; easy to test; “Long” track record; digital glue of SM
- @jewelss: bc it’s cost-effective & allows u to form a personal relationship w/ a consumer by way of their inbox! 
- @thecmunzproject: Email marketing works because it opens up a conversation that otherwise you could not have with your members.
- @LorenMcDonald: Email marketing works because when done correctly no marketing comms channel resonates more w/ subscribers & delivers higher ROI
