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.
Looks excited with feature have by this website for notification new coins listing, there are have many feature for sending us alert when new coins listing from email, SMS, browse notification until phone call.
I like with feature from this site have support all exchange and most recommended site looking for some one who interested for trading in new coins listing.
Usually I use with social media linked with all exchange and need time for updating when getting new coins listing, but with above site we don't need check one by one with social media exchange account to check new coins listing on their exchange market.
