I mean, max message for hours/day and other time delay i should respect
Are you trying to DM your followers or people that are not following you (extracted users)? You can use the settings @Luca posted. They should be safe for new accounts as well. I personally set the daily limit to 30 DMs per day.
Limits can vary from account to account. Your older account should be able to send more messages than some newly created account.
I agree with Luca, don’t go over 20-25 DMs per day, meaning don’t send more than 1 message per hour.
