Seamless and easy both signal that something went well for the person doing it, but they're answering different questions entirely.
"Seamless" means the audience is spared friction across connected steps. "Easy" just means a single task has low difficulty. One is a claim about a step's difficulty; the other is a claim about whether multiple connected steps or touchpoints joined without the audience feeling the seams.
The test: one task's difficulty, or a join between touchpoints?
"Setting up two-factor authentication with a single prompt is easy -- it's a low-complexity, one-step task, not a claim about connected parts joining."
One prompt, one action, done. There's no second system or later stage this connects to -- it's just a task with a low bar to clear, and "easy" describes exactly that bar.
"Retaining a customer's filter settings when they move from the mobile app to the desktop site is seamless -- it's about continuity across two touchpoints, not about how hard any one step was."
Here the difficulty of any single step isn't even the point -- the customer probably doesn't do anything at all. What makes it seamless is that a setting they configured on one touchpoint carried over invisibly to another. "Easy" wouldn't be wrong exactly, but it would be answering a question nobody asked, because there was no task to rate the difficulty of in the first place.

Calling a genuinely connected, multi-step process merely "easy" undersells a real continuity achievement -- it reduces a hard-won cross-system join to a claim about difficulty. And calling a single simple task "seamless" overstates it, reaching for a continuity claim where there was never more than one step to begin with. Both directions of the swap misdescribe what actually happened.
Practice scenarios
Practice choosing between seamless and easy in situations like:
- describing a single, low-effort task someone just completed
- describing a setting or piece of context that carried over between two touchpoints
- catching a continuity achievement that's being undersold as merely "easy"
Useful practice phrases:
- "That's easy -- it's one low-complexity step, nothing more."
- "That's seamless -- the setting carried over between [touchpoint A] and [touchpoint B]."
- "Calling that seamless overstates it; it was really just one easy step."
