This article extends the empirical evidence for the use of e-newsletters in parliamentary communication in between elections. It assesses the effect of electoral incentives and parliamentary institutions on members (MPs1) from all four legislatures in the UK. I find that electoral incentives to cultivate a personal vote increase the e-newsletter usage by MPs. However, being an MP in subnational parliaments or smaller parties decreases it. These findings throw a fresh light on why only some parliamentarians are happy to adopt new and seemingly resource-efficient ways to reach out to voters.
