What is the life span of an email address?

I’m looking for some information on the average life span of a consumer email address. Reports from Fresh address’ ECOA program show that the average email list churns about 30% a year.

My reports tend to agree with this too (~2-4% a month), but this still doesn’t answer the question “How long does the average consumer use the same email address for before switching and moving to a new account?” 1 yr, 2, yrs, 5?

Anyone have insight into this?

  1. This may be a bit off topic, but I’m more interested in step #5 in the FA process:

    We send out a branded “Permission Message” to the updated email addresses to ensure deliverability and permission; our “Permission Message” includes our exclusive Email Change of Address link, ensuring the capture of your customers’ current preferred email address.

    Love to learn more about their “permission message.” What does that mean? Opt-in? Opt-out?

  2. I cannot remember the exact document/report this was in, but I found this:

    “Approximately a third of the online US population creates a new email address each year” – JupiterResearch, July 08’
