The mixtape features guest appearances from Young Dro, Gucci Mane, Ari Lennox, Cam'ron, Central Cee, Bas, Daylyt, and Ab-Soul.

Following the release of the mixtape, Cole faced backlash from fans and reporters after allegedly making what were perceived to be transphobic comments on the project's eighth track, "Pi".

Writing a positive review for Clash, Robin Murray described how the mixtape's tracks, excluding "7 Minute Drill", feel like "exhilarating dip[s] into some of J. Cole's core tropes".

[13] In a middling review for Pitchfork, Paul A. Thompson wrote that despite "plenty of compelling... rhythmic, textural, and even personal elements" on Might Delete Later, the mixtape's repeated declarations of greatness and demands for recognition are ultimately "rendered vacant and vaguely sad" after Cole's removal of "7 Minute Drill" from the project.

[16] Writing a negative review for Sputnikmusic, Dakota West Foss wrote that the mixtape's "bars and punchlines" are those "that scan like [a] parody," saying that Might Delete Later "is a miscalculation at every level" and comparing the project to Chance the Rapper's underwhelming studio album The Big Day.
