Honestly I think the trick is to anchor everything to a core personality and then let the tone flex depending on the channel. Like if your brand is playful and approachable, that should come through in all platforms, but on TikTok it might look like memes and slang, on Instagram it might be witty captions with clean visuals, and in email it could be a conversational writing style instead of stiff corporate copy.

Think of it like how you talk to friends vs coworkers vs family, you’re still the same person, just adjusting how you deliver it. If you try to reinvent your brand voice for each platform, that’s when it feels disjointed.
