If/when I’m your DM, the damage from things like hunter’s mark, hail of thorns, spike growth, ensnaring strike, and thorn whip are 100% magical, so they all bypass resistances and immunities, even if delivered by a non-magical source like a longbow or thrown rock.
All of these damage dealing effects are fueled by spell slots, and that is actually covered in the sage advice compendium.
Like with so much of the ranger class, the spells are part of their class features, interwoven and perhaps even hidden from plain sight.
The damage from hunter’s mark is magical of whatever type used by the delivery system, piercing, bludgeoning, or slashing.
Just as a warlock can do 1d10+x of force and 1d6 of necrotic, a ranger can do 1d8+x of non-magical piercing and 1d6 of magical piercing.
