Shopify Flow - Exclude certain Emails from sending Emails

[Wwwes]

Dear,

I'm recently moved to Shopify and I try to work with the app "Flows". 
This is pretty straight forward, however I want to exclude certain emails from our mailing list. 
Emails such as tracking and other marketing emails.

The emails are all ending on the same part @xxx.com. So I can build a flow on that part, but the "then" option is not possible unfortunately... 

Hopefully you can help me.

Thank you very much. 

With kind regards,
Wwes

For emails send through Flow, you can add a condition that checks if the email "includes" a certain string like a domain.

Hey Paul,

Thank you for replying. 
This part of the workflow is now running, however I'm not able to exclude this customers from the mailing list. 
The "Then" action doesn't include such a thing as "don't send an email to these customers". 

Could you maybe tell me a workaround for this?

A condition if checking is a condition is true. If not, it goes to the "Then" path. So if you check for that email, the then path will be when it doesn't have that email.

So that part I can get working, but within the "Then" options I want an option where we can say: "Then don't send any emails to this customer from Shopify"

You can't prevent them from getting Order confirmation emails and stuff like that, but you can block marketing emails by unsubscribing them from marketing (use Send Admin API request)
