Sending limit guideline is typically 50 email recipients per hour or 500 per day. (spam protection limited)
Sending limits apply to sending from the UK only when directly connected to the TalkTalk network - limits on sending off-network and outside the UK depend on country and could be as few as 1 per hour.
So if you're sending a group email make sure the groups are no more than 50 recipients each. eg if you have 200 contacts then create 4 groups of 50 recipients and send the email out over 3 - 4 hours.
