Is this currently an existing feature request?
Yes, just submitted.
Wishlist item
Automate emails being sent to subscribers based on blog tags and email segments and/or label. And automate adding subscribers to segments based on selections in Wix Forms.
What current pain point are you facing?
I’m unable to automatically send emails in a targeted way when I post a new email with content that they’re interested in. Currently, all subscribers will be notified when I post a new blog even if it’s something that they’re not interested in.
Do you have a current workaround that you’re using?
I would have to manually create a email to the segment of the new blog.
Describe the feature you need and how it would work. (Bonus points for mockups 
)
Set up an automation that is triggered when a new blog is posted. For example someone subscribes to my blog and is interested in apples and bananas, they check those two subjects and is added into the apples, bananas segment. Now every time I post a blog that has a tag that I select in the automation the subscriber gets an email about the new blog.
In Automation
Trigger New Blog
if
Member segment (or Label) is apples, bananas
and
Bblog category is apples, bananas*
Send email.
How will this impact you?
It would help me target my audience when I post new articles and help prevent sending subscribers content they aren’t interested in.
