Yes. The Department of Homeland Security suggests that ESTA apply 3 days before your departure to the United States. But these are just guidelines.
With the VWP, travelers are not required to indicate the itinerary during their stay in the United States, so they can have the ESTA established without this information.

ESTA can therefore be obtained even if your trip to the United States has not yet been planned.

In general it is recommended to indicate your own route as much as possible when requesting ESTA.

This was a good thing, as all future communications on his travel authorization, including the expiry date, will be made by e-mail.
Thanks to this update, Marta will receive future e-mails without any problems.
