I just sent a batch email to 80 recipients, with 3 attached files (pdf format) of a total size of 13.9mo. The files urls are dropbox files urls (where I set dl=1= at the end so the file is downloadable). When testing with a single test email (no batch), I don’t have any problem.
With batch, a lot of emails have corrupted files joined, their size is not the real file size, as if Brevo failed to download the file from dropbox fully, ended up with corrupted files. All emails have different working and broken files.
I send email attachment as mentioned here : Send a transactional email.
What can be the culprit, why some emails have all working files and some other none ?
Thanks in advance for the help
