How do I pass binary data and Json into 1 node correctly?

Sadly this approach did not work, but I fell upon a solution that takes tones of RAM if the amount of recipient is too high

This solution proved itself to work with 1 recipient, but fails with 2 and more due to the google node reading all the binary data as a whole a trying to push it through (my theory atleast):

I’m thinking of a loop solution to merge 1 row at a time with the binary data, push the e-mail though and then get back to fetch one more row
