Sure.

We have CSS in our area, and I recently had a home that came back on the market.   Sent all agents that showed it first, and two of those agents re-wrote.

Yes, I would call and/or send an email telling them.

I would email them.

Yes. If they had clients who expressed strong interest I always let them know it is coming back on the market.

I do, espcecially the ones whose clients lost the bidding war.

Definitely!  If I can get one of those agents to write an offer before it goes back on the market, even better!

I usually text or email if there is a price change or some change in a property's situation that they showed interest in.

At times I do depends on the feedback I had received

Usually, I call my own buyer prospects first, as I know everyone does.

In most cases I have a back up in place.

If not I only contact those agents whose buyer showed the house meet their needs and make them aware the short time available for their offer.

If the cause of the failed deal compels the seller to  alter, repair, replace, adjust, that will be exploited in the second contact.

Then I indicate I will pull out all the stops to reintroduce property into market. 

You bet, it's your job to create kaos when the listing goes back on the market. As soon as they say it's gonna crash - I'm on the phone or email.

ShowingTime sends an auto response when it goes back on to all that showed it if you use that in your office.

Yes.  It also is important to ensure that your listing agreement covers the ongoing selling period.

It goes into the mls "subject to cancellation" --- that's the widest source of "spreading the news" before anything else.   

yes, that's exactly what the agents do for whom I market....

I either call or email them.

I'm a get-the-ducks-in-a-row person, so I'd probably wait until all necessary documents are signed by all parties and any necessary updates had been made to relevant disclosure documents (such as if it fell through due to inspection issues) and the seller has given me the official go-ahead to put it back on the market vs. withdraw.

By that point, though, the official change in status shouldn't be far behind. Hours maybe? Less, perhaps, if I did that first versus reaching out to brokers? So ultimately I suppose I'm saying I probably wouldn't be reaching out until it was officially back on the market, but would push it hard just as soon as I clicked submit on the status change. :0)

Sure great way to possible get a quick offer.
