Guest checkout and trigger acymailing mass action filter

Is it possible to trigger the mass action filter of acymailing for users who checkout as guests? Currently, I'm able to trigger the filters only when the users register upon checkout and purchase the product, but I would like to streamline the checkout process and have users checkout as guest. But when they checkout as guest, acymailing or joomla is not able to capture their user id details and trigger the filter. How do I achieve that?

Hello,

An HikaShop guest user do not have any Joomla account assign so it does not have an Acymailing user (which is also related to the Joomla account).
Afterwards the mass action system do not have integration with third party (like Acymailing, HikaSerial or HikaMarket) but that's something we started to improve for a future release.
But Acymailing have an integration with HikaShop so a lot of things are already possible via the generic triggers and the Acymailing feature (like auto-newsletters or filtering).

Regards,
