Sendgrid account is setup, sender (in Sendgrid) also,
plugin in my app is working well when sending to email address other than yahoo.fr or yahoo.com
Logs in bubble: the workflow activate the “send action”
log activity in sendgrid :
and detail for the “not delivered” :
in the yahoo help about error-codes ( Yahoo Error Codes
SO it is not directly a probem with the plugin because it was working at least one time, I cant go on with my app !!!
I would ike to know if somebody has already had this blocking problem ?
Any advice to fix or unlock?
Thank you for the time you’ll take to answer
