But the interesting thing is that of all the email subscriptions I cancelled, only one asked me why I was done with their newsletter. This is an opportunity to understand how you can make your product better, but instead of putting in a simple question on the unsubscribe form, they just lose a customer and never know why.
Most businesses don't get the opportunity to hear a final word from a lost customer. They just go away. If you are sending an email newsletter, don't annoy an already annoyed customer by trying to mine them for a long survey, but ask one simple question:
We'd like to know why you're unsubscribing is it because:
a) I have too many emails
b) I don't find value in your content
c) I've changed jobs, & this is no longer relevant to me
d) It's not you, it's me
Craft an easy question, offer simple solutions to gain information, and if you see a trend that there's something wrong with your content, change it. Whatever you do, don't forget to learn from your losses.
