Maybe this will help
https://cryptocurrencyalerting.com/new-coin-listings.htmlThey offer multiple notifications like email, sms and telegram bot. I wouldn't recommend using your regular email and number for this service since you never know what they will do with it. You could be getting a bunch of spams and phishing links after registering.
I already tried that site but they dont provide alert listings for all exchanges that i need.
I don’t think there is any alert of such as I have only seen alert for newly listed coins on the coin trackers and not on any of this ones if you need the one for new exchange listing I will advise you join most of the exchange social media channels both Facebook, IG, X and even telegram so that all the listing news which are announced there will also be gotten by you.
I believe one of the reason you need newly listed for is to join the train before the coins/tokens get hype and pumped in the market, try check out binance and other exchanges that make use of social media regularly to announce there listing.
