  We revisit and extend the correspondence between black holes, domain walls
and fluxes in type IIA compactifications. We argue that these three systems can
be described by the same supergravity effective action, modulo proper
identifications and adjustments. Then, we apply the correspondence to
investigate swampland conjectures on de Sitter and anti-de Sitter vacua, as
well as on the black hole entropy. We show that, in certain cases, swampland
conjectures can be motivated from properties of black hole solutions, such as
positiveness of the entropy. This provides a bottom-up rationale which is
complementary to the usual tests in string theory. When asking for an agreement
between the anti-de Sitter and the black hole entropy distance conjectures, we
are led to an extension of the correspondence which includes geometric fluxes
and the associated Kaluza-Klein monopoles domain walls. Finally, we point out
that the anti-de Sitter distance conjecture is naturally implemented in certain
asymptotically anti-de Sitter black holes as a consequence of a constraint
involving black hole charges and supergravity gauge couplings.
