I have a small list of 160 subscribers and it looks so strange to me that I have a really low open rate for the emails I send out.
It looks like it's always around 20%. I thought it was because of spam filters so I checked on SendGrid and the Bounces and Spam Reports are close to zero.
So I'm wondering... What happens? What's the sense in receive a mail every 2 days, not open them and not unsubscribe?
80% of people just delete mails like that?
And do you have any advice to raise my open rate?
Thanks for your help!
