Does this happen irrespective of what device you use to send the emails and irrespective of whether you are on your home Internet or mobile data for example?
If it only occurs when on you home internet it may be associated with your IP address. Try turning off your router for 30 minutes to start a new session and try again.
Failing that, Unfortunately, support staff are no longer available here and this will require you contact TalkTalk directly as the forum is now peer to peer and this is something we are, on this occasion, unable to help you with.
Please see the link in my signature for ways to contact TalkTalk.
From the 29th of March our TalkTalk Community will move to peer-to-peer support and the TalkTalk team will no longer be here to support with queries. Don’t worry we still have plenty of ways to reach out if you need to speak to TalkTalk directly. For more details check out the link here:
