How to send files attachments with Postmark in Bubble?

Need help
1

Hello,

I’m currently using Postmark to send emails from my app. I’ve been trying to send an email with file attachments using the “Send basic email” action, but it doesn’t work.
I’ve tried passing a list of files and even a list of URLs in the “attachments” field, but when I include anything there, the email just doesn’t get sent — and it seems like Postmark never even receives the request.
What’s odd is that there’s no error showing in the Bubble logs either.

Have you already used this action with Postmark and managed to attach files successfully?
Any help would be greatly appreciated!

You said your file is around 200KB. But your file is actually more bigger? If the PDF file is big, then one option is not to send the PDF but include the link to the PDF file that the recipient can download instead.

i would recommend the same, anything 10mb+ i would send a link it can take a while to download when you include it in an email and uses a bunch of email storage for your end user
