A good administrative assistant cover letter opens with a specific reason for applying, backs it with one or two concrete wins, and closes with a clear next step. Copy this and swap in your details.
I'm applying for the Administrative Assistant role at your firm. After five years running the operations backbone of a 60-person consultancy, I'm looking to bring the same reliability and initiative to your team.
I coordinate calendars, travel, and expenses for the leadership group, and I own the accounts-payable side in QuickBooks — 200+ invoices/month with a 90% reduction in billing errors after I rebuilt the workflow.
The scope of the role you posted — combining executive support with vendor and event coordination — is exactly the mix I most enjoy.
I'd welcome a short call to talk through how I'd approach the first 30 days. Thank you for the consideration.
Sincerely, [Your Name]
Tips for this letter
Address a real person if you can find one — 'Dear Hiring Team' is fine as a fallback.
Keep it under 300 words. Recruiters skim.
Never restate the resume — pick one story and go deep.
End with a specific next step, not 'I look forward to hearing from you.'
Frequently asked questions
Do I still need a cover letter in 2026?
For applications with a real human review — yes. It's the #1 tie-breaker between similar candidates. For pure ATS pipelines, it matters less.
How long should the letter be?
3 short paragraphs, 250–300 words total. One page maximum. Anything longer gets skimmed.
Should I mention the company by name?
Always. A cover letter that could be sent to anyone gets ignored by everyone.
