We are using the SendGridConnector for sending emails. Sending single emails works fine, but we also want to use the server action Send_MultipleEmail of the asset to send newsletters. However emails don't get sent anymore when using this action. In the dashboard of SendGrid I can see the To email address is empty, while it's clearly filled in the action.
For this action it's needed to put the To email address in the Request --> Personalization --> To field. The Personalizations items will be added to the Personalization list.
So can anyone tell me what's going wrong here? It worked in the past, so I don't understand what has changed. See also screenshots of the logic.
I think there are a few things you should pay attention to when sending it. If the email address you passed in is correct, you can check the data being sent in the email (Upload/Send file: ~10 MB). You can try removing the file and testing again to see if that’s the cause.
