When sending email from platformsh the recipient gets a ‘via platformsh’ appended. I understand platformsh uses sendgrid. How should i configure my domain so I don’t get the ‘via’ platformsh message?
You have to set up DKIM on your domain. Unfortunately we do not offer white-labeling them.
Please refer to :
You will have to set up your own sendgrid account (or another email provider) if you want to enable white-labeling.
