The FBI documents do not reveal what Obama’s pseudonym was, or what was in the text of the email. The subject, “Re: Congratulations,” combined with the date (June 28, 2012) suggests it may have been about the Supreme Court’s ruling upholding the constitutionality of Obamacare.

The email was never previously released, with lawyers citing “presidential communications privilege” to avoid turning them over under the Freedom of Information Act.
