What is the Islamic etiquette to reply to emails? If an email starts with Salam, does it not become obligatory for a Muslim to reply to it?
Bismillah
Thank you for your question. It is generally praiseworthy to be an approachable and kind person in normal circumstances. However, that is within the bounds of wisdom and chastity. It is not necessary to reply a typed salaam whether that be by email or other forms of instant messenger.
May you always be successful.
