I have received a letter from my investment company saying that their emails to me have been bounced back. The email address that they appear to have been using is correct and I have logged in to the shareholder account and double checked contact details there. They have not told me what the bounce-back emails say. However, I note that they have a very long domain (36 characters); is this likely to have an impact on emails from them getting through and is there a way of adding them to a safe senders list. I have done so in Outlook but their emails don't seem to e getting through at all as nothing is showing in the Junk email folder.
