Senior Copywriter Cover Letter Sample

Dear Creative Lead,

My portfolio is at yourdomain.com — the case study most relevant to your brand is the rebrand voice work I led for a fintech earlier this year. The new homepage tested 38% higher on conversion than the prior version, and the headline I wrote ran on their billboards for the next two quarters.

I'm a copywriter with five years of in-house and agency experience, fluent across long-form (white papers, landing pages, email sequences) and short-form (headlines, social, product UI). My current role is at a Series B B2B SaaS where I own the brand voice document, write across 6-8 campaigns per quarter, and partner with performance marketing on testing creative.

What I'd bring to {{Company}} is the kind of voice that's recognizable without being forced, plus the discipline to file clean drafts on schedule. I take briefs seriously, ask sharper questions than most writers, and treat editing as the most important part of the job.

I'd welcome the chance to walk through the work. Thank you for the consideration.

Best regards,

Your Name

Note: Replace {{Company}} with the actual employer name and tailor the second paragraph to match the specific job description.
