There is really no need to hijack another thread in the forum post. Even if your issue is similar, it can be completely different
I can only repeat what I already wrote above
To provide you with the best assistance possible, I kindly request that you submit a support ticket through our website at https://www.acymailing.com/support/. Our team will be able to efficiently and effectively provide you with the assistance you need.
Also, you can open a separate ticket to list the feature which you are missing from AcyMailing v8, so our developers can take it into the consideration, since support for v5 will definitely be stopped by the end of January 2024.
Thank you for your understanding!
