Hi,
I encouter a problem and i don’t understand what happens :
– on system/delivery panel if i made a test, it’s ok, i receive the mail
– on newsletter if i put the same recipient email in test subscriber, i don’t receive the mail
In the log i have this line: ERROR – 8.9.7 – 103,5 Mo/512 Mo – xxxxx > HTTP Error code 400 {“code”:”invalid_parameter”,”message”:”Invalid headers”}
I try to send a blank newsletter and it’s the same. I use brevo addon.
Thanks for help.
