After posting it, I think I found the solution myself . I’ve added this Additional Filter to the first E-Mail:

I think this should work. Or is there a better way to do it?

Thank you!

Hi @bluecat 

The way you’ve found should work, and it’s one way to do it. Here you’re setting the Filter on a Message (Email) level.
For Abandoned Cart we usually filter people on a Flow level, and we recommend putting a larger time frame in the Filter, as shown in the image below.

We recommend using a larger time frame (15, 30 or more days) for two reasons:

• If someone abandon their cart very often (for example every day), they will receive the same looking Emails every day. After several days, it start to look like spam and it start to lose it’s value. That’s why we want to give them some time to “forget” about these kind of emails and for the email provider algorithms to “refresh” from the same Email.
• The second reason, especially when you’re offering discount codes in the Abandoned Cart Flow, is to avoid people abusing the Flow. If someone recognizes that every time they abandon their cart in your shop, they will receive a discount code the very next day, they might abuse that and whenever they want to buy something, they will abandon the checkout and wait for the discount code.

Hope this helps!

Many thanks for the quick answer and the valuable tips. Has been very helpful to me!
