I am not getting "to" when email received by the receiver
I am using cloud function to send an email when email received it doesn't have "to" email address. Please see attached image.
My cloud function detail: built with: Dart Email Provider: smtp2go

TL;DR
Emails sent via the cloud function are missing the "To" field when received by the receiver. The issue is likely with the configuration of the cloud function or SMTP2GO settings. The provided email message headers show "undisclosed-recipients" in the "To" field. Review the cloud function setup and SMTP2GO configuration to ensure the proper recipient address is included in the email.Messaging configuration
