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.
