Mayor de Blasio admitted Wednesday that he’s now much more cautious about what he writes – mere days after claiming his release of more than 14,000 pages of City Hall emails proved he’s all about “transparency.”

“Yeah, it has caused me to email less and, to some extent, speak differently in emails,” said the mayor, who was forced to produce the documents following a lawsuit by The Post and NY1.

The document dump showed de Blasio was fixated on boosting his national profile and furious when press coverage of his administration wasn’t entirely positive.

“I think everyone believed that they were doing the normal back-and-forth kind of conversation that you do with your colleagues,” the mayor added of the emails he was forced to release..

“No one thought these were things that were going to be published one day, and it definitely is smart to use email less. That’s the bottom line.”

De Blasio also stuck by his comments Monday night on NY1 when he claimed he’s a champion of “transparency.”

The email dump occurred while the nation was transfixed on Supreme Court nominee Brett Kavanaugh’s confirmation hearing.

“My point was not that the court didn’t require it — and I still think that was wrong because everyone was operating under legal guidance and thought they were doing things appropriately,” de Blasio said during an unrelated lower Manhattan press conference.

“But my point was all that information is out. I don’t think you’ve ever seen as many emails from a mayor to [staff and other associates] in this much detail in the history of the mayoralty.”

“I’m a little less obsessed with the release date then all of you because I think transparency is transparency,” he added. “It’s out there in the public domain permanently.”
