According to MailChimp stats on our mailing list (that receives a monthly e-mail), I found out a set of members that never open our mails.
Typically, they opened it once, long ago, then stopped (either classed our mails as spam, or developed an automatic "move-to-trash" reflex).
I don't feel very good at continuing sending mails to these people since, as a matter of fact, they don't want to receive our mails, so I'm wondering if it's a good initiative to unsubscribe them and how would be the best way to do it.
Option 1 I wonder if it's useful to send a mail that would go like
Hey, looks like you don't read our mails, have you considered unsubscribing?
(have to find a good way to write it down without being rude, of course...)
But since these people don't read our mails, I'm afraid this would be completely useless (and harmless).
Option 2 On the other side, I could simply unsubscribe them with no previous warning, but sending a mail like
Okay, we got it, never going to bug you again. Bye.
Option 3 The last option is unsubscribing silently. No additional mails are sent. Just disappear.
Do you have any advice on the subject?
