Yes, you can use it in professional emails, especially when responding to someone sharing information or insights. For instance, if a colleague shares market data, replying with 'How interesting. Did we analyze the regional impact?' shows engagement politely.

Depending on the context and desired level of formality, you could use: 'That's fascinating!' (more formal/enthusiastic), 'Really?' (informal/surprised), 'No kidding!' (very informal/surprised), 'Wow!' (general surprise), or 'I see' (neutral acknowledgement).

Absolutely! Tone of voice is key. If said with a flat, drawn-out, or overly enthusiastic tone, it can imply you find the information boring or unbelievable. It's a common way sarcasm is conveyed in spoken English.

A frequent mistake is using it in situations that require sympathy or empathy, such as when someone shares bad news like illness or loss. In these cases, 'How interesting!' sounds cold and inappropriate, and phrases like 'I'm so sorry' are needed instead.

It's generally best to avoid 'How interesting!' when someone is complaining unless they are sharing a particularly unique or unexpected reason for their complaint. Usually, empathetic responses like 'That sounds difficult' or 'I understand' are more appropriate.

Very informal slang includes phrases like 'No way!', 'Get out!', or 'Shut up!' (used playfully). These express strong surprise but are much more casual and should only be used with close friends.

Pair it with a follow-up question or a specific comment. For example, 'How interesting. I hadn't considered the impact on supply chain. Could you elaborate?' This shows you're not just saying it politely but are genuinely processing the information.

The core meaning remains consistent across major English-speaking regions. While slang variations might differ regionally (e.g., 'Get out!' in the US), the standard phrase 'How interesting!' is universally understood to express curiosity.

For mild surprises, 'How interesting!' works perfectly. You don't need a major revelation. Even learning a small new detail about a topic you thought you knew well can warrant this response.

Generally, no. It's best reserved for neutral or positive discoveries and information. Using it for negative events sounds dismissive. For negative news, focus on empathetic phrases like 'I'm sorry to hear that' or 'That's unfortunate.'
