 * Hi guys!
 * I’ve searched through this forum and on Google but couldn’t find a solution.
 * Everytime I try to attach an invoice to the “Customer invoice/Order details (
   manual mail)” mail, I get the following error in the mail body:
 * —-_SiB-13420531d1210b27-Part_1–
 * —-_SiB-13420531d1210b27-Part_1–
 * When the invoice is not attached to this mail, it gets displayed perfectly right.
   I use Newsletter, SMTP, Email marketing and Subscribe forms by Sendinblue plugin.
 * Thanks a lot for the help!
 * The page I need help with: _[[log in](https://login.wordpress.org/?redirect_to=https%3A%2F%2Fwordpress.org%2Fsupport%2Ftopic%2Fmail-error-when-invoice-attached%2F%3Foutput_format%3Dmd&locale=en_US)
   to see the link]_

 * Hi! Could you try sending this without the Sendinblue plugin? It seems like other
   users are facing issues with attachments too: [https://wordpress.org/support/topic/transactional-mails-with-attachment-issue/](https://wordpress.org/support/topic/transactional-mails-with-attachment-issue/)

 * Thanks for the quick answer Ewout!
 * To be honest, I’d rather not attach the invoice than risk to mess up my SendinBlue
   settings.. it took me long to make it work 😅
 * I’ll see what I can do with SIB support.
 * Cheers!

 * It works fine bypassing SendInblue, we’re actually trying to investigate with
   the help of SIB support.

 * Hi guys!
 * I haven’t tested it yet, but it could be fixed:
 * Newsletter, SMTP, Email marketing and Subscribe forms by Sendinblue
    3.1.0 Bug
   fixes Fixed the blank/suspicious mail content with PDF attachments.
 * Fingers crossed!

 * That looks promising indeed, would love if you can confirm if that update indeed
   fixes the issue.
