Hi @pixtweaks,

I tried to replicate your case on my end but no issue is found. I tested with different attachments i.e. pdf, jpg, and txt. All are working fine. Could you please specify the attachments in which you encountered the error? This will help us identify the issue more accurately.

Also please share the diagnostic test report with us. You can access the diagnostic test report from here.

Thanks and Regards,

Hi @furqanfazal, thank you for your quick response!
I’ve created a simple plugin that tries to send itself. It will fail on my local and production that are connected to postmark via the same API key. if I remove an attachment, it will go through. Under the plugin are test data from both environments I’m testing. Please use your email to test ??

Hi @pixtweaks,

I tried to replicate your case on my end along with a sample test plugin given by you. On my end, no issue is found. Everything is working fine. It might be an environment-related issue or the path of the file is not properly defined or might be possible some other plugins cause conflict or override the attachments.

I have attached a video of my test with your sample test plugin for your reference. You can troubleshoot the issue by using some other plugin i.e. contact form to send an email with attachments. If you need further assistance you can contact our?technical support channel?so that we can connect you directly with our technical team.

Thank you for your patience and understanding.

Thanks and Regards,
