Vodafone (New Zealand) Email Closure

Vodafone (NZ) is reporting that they have shut down their email service as of November 30, 2017.

This affects the following domains: clear.net.nz, es.co.nz, ihug.co.nz, paradise.net.nz, pcconnect.co.nz, quik.co.nz, vodafone.co.nz, vodafone.net.nz, and wave.co.nz.

However, don't purge those addresses from your lists just yet. Vodafone is allowing users to (at least temporarily) continue to receive mail at those accounts, and the mail will be forwarded on to a new email address as configured by the user.

What should senders do? Watch for bounces; bounces will definitely increase at those domains. Those bounces mean that users have not set up email forwarding, and their accounts are thus now closed. You may want to attempt to mail those subscribers, to find the ones whose accounts still forward, to request that they update their email addresses registered with you.

Reference: Top MAGY Domains

Sometimes it is handy to have a list of the top MAGY (Microsoft, AOL, Google, Yahoo) email domains. Here's what I've compiled based on current and prior research, plus input from readers.

AOL and Yahoo are merging, but I've left them distinct for now. Also, some of these domains might not be common email domains, but they all seem to have valid MX records and thus if you're looking for a list of domains to, for example, exempt from validity checking so that they never falsely appear to be dead domains, it'll still come in handy.

If you use this to group domains to count sending mail volume by ISP, it will be slightly imperfect, as I've included the corporate domains (microsoft.com, google.com, teamaol.com, oath.com, yahoo-inc.com) that may use separate mail systems. However, your send volume to those domains is probably pretty low compared to the consumer mailboxes, so for "back of napkin" kind of math in a pinch, it might do just fine.

Note that the intent here is to list email domains owned and used by that given provider; not to list every possible customer domain that points at the ISP's mail servers. I'm not capturing Google Apps domains, Yahoo Business Hosting domains, or anything like that. That's out of scope for this exercise.
