How to create effective e-mail newsletters?

Question

Marketing

Hello everyone, we recently did a newsletter for March 8 on women's products for the skin, face, hands.
Target audience - girls, women from 18 to 60 years old.
There are enough openings of letters, there are no transitions to the site.
Transitions were not recorded by either Google Analytics or the service through which the mailing was done.
The letter itself seems to be interesting, it was designed and created at a meeting by several people - for evaluation from the outside and suggestion of interesting ideas.
What could be the reason, what do you think?
Thanks in advance for any versions.

Answer 1

well, in the mailing service and look at the percentage of delivery, the percentage of openings and the percentage of transitions, and now you already have a funnel for work,
