Marketing Manager
[Company name]
[City, State]

Dear [Hiring manager's name],

At Birchwater Home Goods I support a three-person marketing team by drafting email copy, scheduling our social calendar and keeping our product launch checklist on track, and I'd like to bring that same reliability to [Company name] on a bigger catalog.

I write and schedule 3 to 4 weekly emails in Mailchimp that hold a steady 26% open rate, above our 21% category average, and I built the launch checklist that cut our new-product go-live time from 3 weeks to 9 days. Coordinating our fall trade show booth, on a $6,000 budget, brought in 140 qualified retail leads, our best count in two years.

I design social and email graphics in Canva, keep our HubSpot contact lists current, and proofread every piece of outbound copy against our brand style guide before it goes out. I'm the one who notices when a promo code is about to expire or a landing page link is broken, and I fix it before anyone else has to ask, usually before it costs us a single sale.

I'd welcome the chance to talk about how I could support your team's next launch at [Company name], and I can start as soon as you need an extra set of hands. Thank you for considering my application.

Sincerely,

Avery Chen

Why this letter works

  1. Paragraph 1

    Names the team size and the actual tasks owned

    A marketing manager hiring an assistant wants to know exactly what will come off their plate. Naming the team size and specific responsibilities answers that in the first sentence.

  2. Paragraph 2

    Two numbers beat a benchmark

    An open rate above category average and a launch timeline cut from three weeks to nine days both show the assistant already outperforms a normal baseline, not just keeps up with one.

  3. Paragraph 3

    Shows the catches nobody assigned

    Noticing an expired promo code or a broken link before being asked is the kind of ownership a manager can't easily screen for in an interview, so naming it directly matters.

Questions about marketing assistant cover letters

What should a marketing assistant cover letter include if my experience is mostly support tasks?

Include the process you improved, not just the tasks you completed. A checklist that shortened a launch timeline or an email cadence that beat a benchmark open rate shows initiative beyond following instructions, which is what separates a strong candidate.

Should a marketing assistant mention specific software skills?

Yes, name the ones you actually use, such as Canva, Mailchimp or HubSpot, since many teams need someone who needs no training on their existing tools. Pair each one with something you produced in it.

How long should a marketing assistant cover letter be?

Three to four short paragraphs, around 250 words. Lead with your current responsibilities, give one or two results with numbers, and close with genuine interest in the specific team, not a generic line about loving marketing.
