Thats only from the house, they have to ask the doj to enforce them of invoke enherent contempt; which hasn't been used in almost 100 years.
Ignore a doj subpoena and the come and arrest you.
The DOJ issued the four-page subpoena to multiple Trump campaign officials in early December, seeking more than “two dozen categories of information,” according to the report. One part of the subpoena asks Trump campaign officials if anyone paid for their legal representation and paperwork related to any such agreement.
The subpoena also seeks “all documents and communications” related to Trump’s fundraising activities for a litany of groups outside of his Save America PAC, which has already come under scrutiny. The new subpoenas seek documents related to the Make America Great Again PAC, the Save America Joint Fundraising Committee and the Trump Make America Great Again Committee, including documents related to the “formation, funding and/or use of money” of the groups.
The subpoena also seeks documents related to the creation of an “Election Defense Fund,” which Trump officials ostensibly formed created to raise money from grassroots donors after Trump’s election loss. Officials later testified to the House Jan. 6 committee that the fund technically did not exist but was a way to raise money from people who bought into Trump’s Big Lie.
Prosecutors’ interest in the payments comes after former White House aide Cassidy Hutchinson testified to the Jan. 6 committee that she was initially represented by a Trump-linked lawyer who would not tell her who was paying his fees and said she did not need a formal written retention agreement. >

Are these real subpoenas that people have to respond to, or are they the other kind that one is apparently allowed to ignore? >

These are DOJ subpoenas, not Congressional ones.  Technically, neither can be ignored, but as we've seen, the Congressional ones don't seem to have much recourse when someone does ignore them. >

Well let's hope these have legs, because this whole "ignoring subpoenas if your rich" bullshit has been pretty deflating lately.
