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 provde alerts listings for specfc exchange mexc futures only for mexc spot. I need mexc futures listing alerts.
