Thank you for the update.
Under normal circumstances, emails are delivered almost immediately, although in some cases there may be a short delay depending on your mail server or email provider. Since the confirmation message appeared successfully, it indicates that the email was submitted for sending.
If the email still doesn't arrive after a few minutes, please check your Spam/Junk folder. If it is still missing, kindly let us know which SMTP service or email provider you are using, and we will be happy to investigate further.
