I haven't done email campaigns before, so I recently started emailing them some interesting articles, basically once a week for about few months.
However it seems to me my email open rate is too low. It varies between 38 and 70 opens for the entire list of 350.
And with every time I send them article open rate decreases.
Just to note that I don't push them to buy anything in the articles I basically try to give them value and build trust and once I have it will try to sell product.
So my guess is that my email Subject line is not intriguing enough, or am I wrong.
If that is the case what some good subject lines. I usually say something that provokes curiosity like:
"hey have you ever wondered about this..."
"here is something interesting I stumbled upon recently..."
"something practical about... (half of the article title)"
Any other suggestions on how to increase email open rate?
I'll appreciate it and thank you.
