Error Code 400


I am getting several emails a day recently saying
, a recent task was not executed due to following error - "error > code": 400,
"error > message": "Invalid email address"
I’ve noticed no new subscribers to my Mailerlite list also - how can I fix this please?

Hello @jkfarrelly , try to check Data in, in task history section if that email is legitimate or not.
FYI I'm not from Pabbly connect team, I'm automation freelancer who just helps other Pabbly members.
