Assalamu alikum wa rahmathullah
Is it obligatory to say jawaab to the salaam written in English sent through mail?
Wa alaykum salam wa rahmatuLlahi wa barakatuHu,
Replying to the salam when received in written correspondence is obligatory. (Imam Nawawi’s Kitab al-Adhkar p. 316)
And Allah knows best.
