When expressing gratitude or showing willingness to help, using 'with pleasure' sounds very formal and may be too common. You might want to express your delight using other synonyms such as 'gladly,' 'cheerfully,' 'happily,' 'eagerly,' or 'delightfully.' You may also use 'it would be my pleasure,' 'I'd be happy to,' 'no problem,' or 'don't mention it.' When you're acknowledging a compliment, you might want to use 'thank you so much,' 'I appreciate it,' or 'it means a lot.' Whatever synonym you choose, it's important to show gratitude in a warm and genuine way.
