Try this:
function sendEmailOnDate() {
const ss = SpreadsheetApp.getActive();
const sheet = ss.getSheets()[0];
const dt = new Date(sheet.getRange("A1").getValue());
const dtv = new Date(dt.getFullYear(),dt.getMonth(),dt.getDate()).valueOf()
if (dtv == new Date(new Date().getFullYear(),new Date().getMonth(),new Date().getDate()).valueOf()) {
MailApp.sendEmail("mymail#gmail.com", "Nowa wiadomość", "The date in cell A1 is today");
}
}
