As you may already know, if you use email to SMS more than the web portal it's not always easy to find out the status of a message. We have always offered email delivery receipts to let you know as soon as an email to SMS message has been delivered successfully, but we have now introduced email failure notifications so you know if the message won't be reaching the recipient.
To enable these features just go to the email tab in your options section and tick the relevant boxes to opt in.
