MillyG they're not ads in the sidebar, which can be blocked by an ad-blocker. These are ads appearing actually in the inbox - and no, they're not emails, so they don't get treated like spam. They're adverts, placed there by the email provider and you can't block them. All I've been able to do is remove them. I have more than one email account and in one account I can't even remove them!
Ah, sorry I can’t help then, not something I’ve experienced. I have a hotmail account, well it’s now Outlook these days, and haven’t ever had ads such as you describe Bathsheba. I’ve had the account for years, it’s my main one, and also have a bt internet email account- no ads in the inbox there either. Maybe switch to another email provider? Hope you can sort something out, it must be really annoying.
My experience too Bathsheba. Have had my Hotmail a/c for years, never had this til recently. I can delete by clicking on the dustbin symbol next to the email header but was wondering really if there's any way they can be stopped from appearing
