How to Cold Email a Hiring Manager and Actually Get a Reply

Why cold outreach still works in 2025

Hiring managers feel the pain of the ATS problem as much as candidates do. They post a role, get 800 applications, the ATS surfaces 30, and they privately suspect several strong candidates were filtered out. An email that lands directly in their inbox from a credible-sounding candidate skips the filter entirely. If the message is relevant and the timing is right, it gets read.

The response rate for cold emails to hiring managers is low in absolute terms — typically 10 to 20 percent — but the quality of the outcome when it works is high. A reply from a hiring manager can lead to a conversation, a referral, an interview slot that was not publicly available, or at minimum a name associated with your application when it reaches them via the formal channel. Any of these is worth the ten minutes it takes to write a good email.

Step 1: Find the right person

You are looking for the person who manages the team you would join — not HR, not a talent acquisition partner, not the founder. The hiring manager is the person who will interview you, who feels the gap on their team, and who has the most direct interest in filling the role well.

How to find them:

• LinkedIn. Search the company and filter by department and seniority. For a software engineering role, look for an Engineering Manager or Head of Engineering in the relevant area. For a marketing role, look for a Head of Marketing or Marketing Director. Their connection to the team should be legible from their title and recent activity.
• The job posting itself.Many postings include the team name or even a recruiter's name. The recruiter is not your target, but they can confirm who manages the team.
• Company website and press. For smaller companies, team pages and "about" sections often name team leads directly.

Once you have a name, find their work email. Most companies follow a standard format: firstname@company.com, firstname.lastname@company.com, or f.lastname@company.com. Tools like Hunter.io can verify or surface the pattern used by a given domain.

Step 2: Write a subject line they open

The subject line is doing most of the work. It needs to communicate relevance in under eight words. Hiring managers receive a lot of unsolicited email; vague or salesy subject lines are ignored immediately.

The formula that works: [Role] — [Your most relevant credential or outcome]

• "Senior Data Analyst — 4 yrs SQL, built reporting stack at Monzo"
• "Product Manager role — shipped 3 B2B products, 0 to $2M ARR"
• "Software Engineer (backend) — Go + Kubernetes, fintech background"
• "Marketing Manager — doubled organic traffic at Series B SaaS"

The subject line answers the only question the hiring manager is asking when they scan their inbox: "Is this person worth the thirty seconds it takes to open this?" Give them a reason to say yes immediately.

Step 3: Structure the email for a reply

Cold emails that get replies are short, specific, and end with a single, easy ask. The structure that works:

Keep the whole email under 150 words. Hiring managers read on mobile. Long emails get scrolled past.

Step 4: Follow up — once

If you have not heard back after 5–7 business days, send one follow-up. Keep it to two sentences:

After one follow-up, stop. Sending a third message does not improve your odds and may actively damage your chances if the person is still considering your first email. The follow-up's only job is to surface your original message from a busy inbox — not to pressure.

A note on volume and targeting

Cold outreach scales poorly if it is generic. The same email sent to 50 hiring managers with the company name swapped out performs badly — hiring managers can tell when something is templated. Five targeted, genuinely researched emails outperform fifty copy-paste attempts.

The sweet spot is to combine cold outreach with a strong ATS-optimised application. Submit through the formal channel, then send the cold email on the same day. Reference the application in the email: "I applied via your portal today and wanted to reach out directly." This shows initiative and gives the hiring manager an easy way to find your application in the ATS if they want to move forward.

That combination — a tailored resume that clears the ATS filter plus direct outreach that surfaces you to the decision maker — is the most reliable path to a callback in competitive hiring markets.

The resume you attach matters

If your cold email works and the hiring manager asks for your resume, that document needs to be tailored for the specific role. A generic base resume attached to an otherwise strong cold email undercuts all the work you did. The hiring manager has just told you they are interested — now your resume needs to close the argument.

getinterview.io lets you generate a tailored, ATS-optimised resume for each role in under two minutes. Paste in your base resume and the job description, and the platform — trained on 500,000+ successful CVs — produces an output built to match the specific language and requirements of that role. When your cold email lands, your resume is ready.
