FD renewal - Email /sms from bank may be
Rest - Bank sms/email, Third party apps, Amazon, tata neu, payzapp, CredApp (personal fav as it keeps on reminding through sms/ notification and in WhatsApp), etc etc.
If you have paid one bill in any of the other banking apps (apart from your bank) you will receive timely sms/email from them as a reminder (eg - only credit card from axis - timely reminder).
If you want cashback for utilities, insurance, tax payments I prefer timely reminder with cashback - Tata neu app with Tata neu card.
