When your message already says to send, it goes at once; ask to see it first and you get a draft.
Steps
Open your Freffo group in WhatsApp.
Type, or say it in a voice note: "Krishna ko jawab de do ki maal kal shaam tak aa jayega"
It goes to Krishna at once and Freffo tells you what went. To see it first, say "likh ke dikhao". A message to a group, to a new number, or one that reads like a promotion is always shown first and waits for your "send".
