Something impactful is effective, or makes a strong impression, like an impactful movie that captures your attention and leaves you feeling deeply moved.
Impactful gets a bad rap from a lot of grammar snobs, who consider it a made-up bit of marketing lingo. It's a real word, though, coined in the 1950s and originally used in the context of political and literary theory. Impactful is from the noun impact, "strong effect." To avoid annoying some grammarians, you can substitute words like "meaningful," "effective," or "powerful." Or just go ahead and say, "This was the most impactful summer of my life!"
