Several of our Growth team ideas, such as "Email new editors their impact" and "Email notification replies", rely on having email addresses for editors. We don't currently know how many editors have email addresses associated with their accounts. It is a high priority to find things out on this front by 2018-09-21, because it will materially affect our roadmapping.
The task is to find answers to these questions:
- Over time, what percentage of new account signups give an email address? (TOP PRIORITY)
- How common is it for editors to add an email address to their account at some point after they sign up?
- What is the bounce rate for the email addresses we have for editors who have signed up in the last year? In other words, how reliable are those email addresses?
We definitely need this for Czech and Korean Wikipedias, but if it's easy to produce, it would be good to have them for several other Wikipedias for comparison, like English, German, Arabic, Ukrainian.
