Hi Alexander,

Thank you for following up. I have updated to 24.9.0 and still getting the same error. Here is a code snippet similar to what I am doing.

new Metered().SetMeteredKey("public_key_here", "private_key_here");

var message = new MailMessage{
    From = "from@test.com",
    To = "email1@test.com,email2@test.com", 
    Subject = "subject",
    Body  = "Body"
};

var client = new SmtpClient();

client.SendAsync(message);

Please let me know if you need anything else from me.

Hi @Roos
Thank you for info.

Could you clarify - the error occurs in the client.SendAsync(message) line - is this correct?
Also could you please send a full description of the exception - type, message, call stack would be very helpful.
Thanks.
