I'll usually need this information from you before I start on anything:

1. I need a rundown of your product, features, selling points, release dates, etc.
2. Who is your target audience? I need age, gender, location, and interests or just a look at analytics. This will put me in a competitive spot to create messaging that speaks directly to their audience and resonates with their needs and desires.
3. Who is your competition? I need to know how to differentiate you from your competition and hone in on your unique strengths. 
4. What are your goals with this specific campaign? Other than increasing sales, what else are you trying to do? 
5. Brand guidelines: If you have one, I’d take a look at your brand guidelines deck and make sure that all the copy I write aligns with your voice and style. This is crucial for maintaining customer trust and consistency.
