Follow-up email should be sent within a day from the interview. It is a happy medium of appearing interested and giving the interviewer some time to process your meeting.

Within 24 hrs so you are top of mind with them, but enough time so it demonstrates that you put some thought into what they had to say.
Morning interview: If you had an interview in the morning, your goal should be to send your thank-you email that afternoon. We download an interview hours before air and need plenty of time to write the best segments.

If your interview is on a Friday afternoon, you might want to wait until Monday morning to send after-interview messages. Letting it on Friday afternoon might see your story drown out in the news flow over the weekend.
What if you forget?
It happens to maybe one of you humans reading this, and it happened to me twice-If fewer than 24 hours have elapsed and you haven,t sent your email yet, do not panic Sending a late message is always better than not sending it at all. Apologize briefly for the delay, but spend more time reminding them how appreciative and excited you are about said position.
Appreciation: Go ahead and thank the interviewer for his/her time and the chance to converse about the job.
Recap a point, for example: mention discussion on the interview made an impact on you
Closing — remention thanks and hope to hear from them End your message with a professional closing, like “Best” or “Sincerely”.
