APPARENTLY THERE IS NO SINGLE INDEPENDENT PLATFORM THAT OFFER FREE BULK MESSAGING BE IT VIA SMS, EMAIL OR TELEGRAM.
THE CLOSEST THING TO FREE IS HOSTING A CUSTOM PRIVATE MAIL SERVER BUT IT COMES AT POSSIBLY HIGHER COST IF NOT PROPERLY IMPLEMENTED.
MAIN COST IS RISKING BLOCKING PORT 25 AND IP BAN FROM THE ENTIRE INTERNET.
IT ALSO HAS HIGHER IMPLICATIONS ON SYSTEM HARDWARE, THOUGH IT IS CLOSEST TO FREE.
