Should I explain why I missed the deadline?

Yes, briefly—but only after apologizing and stating the new timeline. Keep it factual, not defensive. 'I underestimated the scope' works. 'The client kept changing requirements' sounds like you're shifting blame. Give context, not excuses.

How soon should I send the apology message?

As soon as you realize you won't hit it. Don't wait until the deadline passes. Flagging it early shows respect and gives people time to adjust their plans. A heads-up beats silence every time.

What if this is the second or third time?

Apologize, then name the pattern. 'This is the second time I've missed a deadline I set, and I need to fix my approach. Here's what I'm changing.' Then actually change it. Words matter less if behavior doesn't shift.

Should I apologize to the whole team or just my manager?

If the whole team was affected, address them. Keep it brief—no need for a company-wide announcement. A message to the core people who depended on your work is enough. Being public shows accountability without being theatrical.

Can I use this if I'm waiting on someone else?

Only if the delay was ultimately your responsibility. 'I should have flagged the blocker sooner' works. 'They didn't get me the info' doesn't—it sounds like you're dodging. You own your deadlines, even when others are part of the chain.
