Marketing hiring managers read cover letters looking for evidence that you can run a campaign and learn from its numbers. A letter that walks through one real campaign, from goal to channel to result, shows more than a list of platforms. It also gives the interviewer something concrete to ask about.
The letter below is fictional. Replace every [bracketed] campaign, figure and company with your own, and only use numbers you measured.
Digital marketing cover letter (fictional)
Dear [Name or Marketing Team],
I am applying for the [Digital Marketing Executive] role at [Company]. Your posting focuses on [channel, e.g. paid social and email], which is where most of my recent work sits.
At [employer or client] I ran a [channel] campaign to [goal]. I set up [targeting / email sequence / content calendar] in [tool], tracked [metric] in [analytics tool], and changed [one thing] after the first [week / test]. The result was [measured result].
I would bring the same habit of testing and reporting to [a specific part of their marketing you have looked at].
I am available from [date]. Thank you for your time.
Kind regards, [Your Name] · [Portfolio or LinkedIn link] · [Email]
Which numbers to use
- Use metrics you tracked yourself, with the period: click-through rate, cost per lead, open rate, follower growth.
- Say what you changed to get the result.
- If you cannot share figures, describe the test and what you learned from it.
- Leave out numbers you cannot explain in an interview.
What if I have no marketing job yet?
Use a campaign you ran for a college club, a small business, a personal project or a course. Say it was a project and give real numbers from it.
Should I link a portfolio?
Yes, if you have campaign examples, content samples or a case study you are allowed to share.
Show the campaign in a portfolio website, pair the letter with a resume, and write it in the cover letter builder.
