A busy brand contact decides whether to keep reading a pitch within the first sentence or two. Everything about a good pitch is designed around that reality: get to the point fast, make the fit obvious, and give them an easy next step.
Before writing a word, know the answers to these:
If any of these is genuinely unclear, that's a sign to go back and research more before writing — not a gap to paper over with enthusiasm.
A pitch that gets read is usually short and follows a predictable shape: a short, relevant subject line; an opening that introduces who you are and who you represent; a line that shows you actually understand the brand (not a generic compliment); a clear explanation of why this creator is a fit; a simple, concrete campaign or content idea; and a specific call to action asking for the next step. Cut anything that doesn't serve one of those jobs.
Every pitch should contain at least one real, specific reason this brand was picked — not filler. Good sources for that reason: a recent product launch, an active campaign, a specific product that fits the creator, real overlap between the creator and the brand's existing content, or a relevant seasonal moment. "I love your brand!" with nothing behind it reads as mass-sent even when it isn't, and gets treated accordingly.
None of this requires being the most creative writer — it requires being specific, short, and easy to say yes to.
