Applying through the portal puts you in a stack of three hundred. A cold email to the person who'll actually manage the role puts you in front of one human who has the power to say "let's talk." The catch: most cold emails get deleted in two seconds because they read like a wall of text from a stranger who wants something.
Done right, this is one of the highest-leverage moves in a job search. Here's how to do it right.
Find the actual hiring manager, not HR
You want the person the role reports to, the engineering manager for an engineering job, the head of marketing for a marketing job. Not the recruiter, not a generic careers inbox.
LinkedIn is the fastest path. Search the company plus the likely title ("engineering manager", "head of design"). Cross-check against the job post, which often hints at the team or the manager's level. For the email address, most companies use a predictable pattern, first.last@ or first@, and you can usually confirm the format from any public address on their site.
If you genuinely can't find the manager, a senior person on the team is a fine second choice. They can forward you internally, which is almost as good.
Keep it to three short paragraphs
The entire email should fit on a phone screen without scrolling. Length is the most common reason these get ignored. Three paragraphs, four at most.
Paragraph one: why them, in one line. Open with something specific to that person or team, not "I came across your company." A recent product launch, a talk they gave, a problem their team is clearly tackling. This proves you're not mass-mailing.
Paragraph two: why you, with one proof. State what you do and give a single concrete result that maps to their need. Not your whole CV. One line that makes them think "this person could help."
Paragraph three: a small, clear ask. Don't ask for a job. Ask for fifteen minutes, or simply whether it makes sense to talk. A low-friction ask gets a reply; a high-friction one gets ignored.
The subject line decides whether it's opened
If the subject reads like marketing, it dies in the preview. Keep it plain and specific. Something like "Backend engineer interested in the payments team" tells the manager exactly what this is and who it's from. Avoid "Opportunity", "Quick question", and anything that smells like a sales sequence.
Write like a person, attach nothing yet
The tone is a peer reaching out, not an applicant begging. Confident, brief, easy to say yes to. Skip the formal throat-clearing ("I am writing to inquire about") and the desperate over-selling.
Don't attach your CV on the first email. An attachment from an unknown sender raises a small flag and asks for effort before they've decided they care. Offer to send it if they're interested, or link your LinkedIn. If they reply, that's when a clean one-page CV earns its place, and turning your LinkedIn into one is quick with a tool like Postulit so you're ready the moment they ask.
One specific sentence about their team beats five generic sentences about yourself. Specificity is the whole game in a cold email.
Follow up once, then stop
No reply in about a week? Send one short follow-up on the same thread, two lines, no guilt-tripping. People are busy and emails get buried; a single nudge is reasonable and often works. After that, let it go. A third and fourth chase reads as desperate and burns the relationship.
If you're sending these alongside a portal application, the cold email and the cover letter are doing related jobs and should sound like the same person, just at different lengths.
The whole thing takes fifteen minutes per company once you've found the manager. Compared to firing applications into a portal and hoping, it's the better use of the same time.
