Your old coworkers, managers and classmates are often the most useful people in a job search, because they already know how you work. The hard part is restarting a conversation that went quiet years ago without it feeling like you only showed up to ask for something.
The short answer: start with people who know your work, open with a specific, genuine check-in, mention your search plainly once they reply, then make one small, concrete ask. Follow up once, and stop if there's no response. Below is how to do each step, with example messages you can adapt.
Who to contact first
You don't need to message everyone. Start with people who already know your work and who are most likely to answer. A short list of 10 to 20 good contacts beats a long list of people who barely remember you.
Sort your connections into three rough tiers before you write anything. This keeps you from spending your best energy on the least likely replies.
- Tier 1: Former managers, close teammates and people you helped directly. They can speak to your work and often respond warmly even after years of silence.
- Tier 2: Classmates, former colleagues from adjacent teams, and people you met at events or in communities you were active in.
- Tier 3: People now working at companies or in roles you are targeting, even if you knew them less well. Keep these for after you've practiced on warmer contacts.
- Skip for now: people you never actually spoke with, and anyone where the relationship ended badly.
Tip Use LinkedIn's connection filters by current company and past company to find former colleagues who have moved to employers on your target list.
Prepare before you hit Message
A dormant contact will usually click your name before replying. Make sure what they see matches what you're about to tell them.
Then find a real reason to write. A specific hook makes the message feel like it comes from you, not from a template.
- Update your headline and About section so they reflect the role you want, not only your last job.
- Open their profile and recent activity. Note a new role, a promotion, a post, a company milestone or an anniversary.
- Recall one concrete shared memory: a project, a manager, a launch, a class, a late night fixing something.
- Decide what you'd eventually like from them (advice, an intro, insight into their company), but don't put it in the first message.
Write a check-in that doesn't open with a request
The first message has one job: restart the conversation. Keep it to two to four sentences, mention something specific, and end with an easy question about them.
Opening with "I'm job hunting, can you refer me?" after five years of silence puts people in an awkward spot. A genuine check-in gives them a chance to reply without obligation, and it makes your later ask feel natural.
- Former manager: "Hi Dana, I saw you moved to Northwind as Director of Ops, congratulations. I still use the weekly review format you set up on the logistics team. How are you finding the new role?"
- Former teammate: "Hey Marco, your post about migrating to the new billing system brought back memories of our 2021 cutover weekend. Hope the second time went smoother! How's the team these days?"
- Classmate: "Hi Priya, it's been a while since the capstone project. I noticed you're in product marketing at a fintech now, which is the direction I've been heading too. How did you make that move?"
Tip If you can't think of one specific detail to mention, that's a sign the contact belongs in a later tier.
How to mention your job search honestly
Once they reply, you can tell them what you're up to. Be plain about it. People respond better to a clear, brief update than to hints they have to decode.
Say what you're looking for in one sentence, specific enough that they could recognize a fit: role, field or type of company. If you were laid off, a short neutral line is enough; you don't need to explain or apologize.
In some cases it's fine to mention the search in the first message, for example with a former manager you were close to, or if they posted that their team is hiring. Even then, lead with the relationship and keep the ask light.
Example
Them: "Great to hear from you! It's been good, busy. What are you up to?" You: "Glad it's going well. On my side, my role was cut in a restructuring last month, so I'm looking for operations manager roles at mid-size logistics or e-commerce companies. Northwind is actually on my list. Would you be open to a 15-minute call sometime to tell me how the ops team works there?"
Tip If you're still employed and searching quietly, say so and ask them to keep it between you.
Turn a warm reply into a specific ask
Vague requests like "let me know if you hear of anything" are easy to agree to and easy to forget. A small, specific ask gets acted on.
- Match the ask to the relationship: advice or a short call from most people; an introduction or referral only from people who know your work or trust you.
- Make it concrete: one company, one role, one person you'd like to meet, or one question.
- Make it easy: offer times, send a short blurb they can forward, and link the job posting if you're asking about a referral.
- Give them an easy out: "No worries if the timing isn't right."
- Thank them whether or not it leads anywhere, and tell them what happened later.
Example
"Thanks so much for the call. If you're comfortable, I'd appreciate an intro to Sam on the fulfillment team. Here's a two-line summary you can forward: 'Alex has six years running warehouse ops for a regional retailer, cut pick errors by redesigning slotting, and is looking for an ops manager role.' Totally fine if that's not possible."

When to follow up, and when to stop
Silence usually means busy, not rude. Plenty of people read a message, mean to answer and lose it under newer ones.
A reasonable pattern is one follow-up after one to two weeks, then stop. If they don't answer the second message, let it rest. You can try again months later if you have a genuinely new reason, like their company announcing an opening or a post of theirs you have something to say about.
- Good follow-up: short, adds something, no guilt. "Hi Marco, just bumping this in case it got buried. Saw your team is hiring a data analyst, which is close to what I do. Happy to chat if you have time."
- Avoid: "Did you see my message?" or multiple nudges in one week.
- Stop if they reply politely but don't engage further. Thank them and move on.
- Keep the relationship alive afterward with an occasional comment on their posts or a congratulations, not only when you need something.
Keeping it personal when you're messaging many people
This article is published by Apply with AI, a Chrome extension that works on LinkedIn and Upwork. Here is how its LinkedIn messaging features fit this workflow, described factually rather than as a recommendation.
Reply with AI adds a button next to LinkedIn's Send button on the Messaging page and in chat windows. It reads the whole conversation and suggests the next message, or writes the one you describe, using your saved facts, resume and the jobs you applied to at their company. The draft goes into the message box; you read it, ask for changes or discard it, and press Send yourself. This suits the reply-and-ask stages above, where each message depends on what the other person said.
Messaging campaigns to your own connections are a separate feature: you can message a described group or a pasted LinkedIn search, in one or several steps with delays, with a set number per day, and the campaign stops for anyone who replies. For reconnecting, keep any campaign to a small, well-defined group, write steps that read like a real check-in, and expect to continue every reply by hand. Auto-reply is different again: it answers unread conversations on an interval, and you can leave categories such as a recruiter about a job, scheduling or offers for yourself.
If you also apply through the LinkedIn job agent, note that auto-submit is on by default; you can turn it off per run or in settings so it stops on the review step for you to press Submit. Details are on the LinkedIn job application agent page, and plans are on the pricing page.
Tip Whatever tool you use, edit every draft so it contains at least one detail only you would know about that person.
Common mistakes to avoid
- Pasting the same message to fifty people. Former colleagues compare notes, and generic messages read as generic.
- Pretending you were "just thinking of them" and then asking for a referral in the next line.
- Attaching your resume to a first check-in.
- Asking someone who barely knows you to vouch for your work.
- Disappearing after they help. Close the loop and say thanks.
- Reconnecting only during a search. A few light touches a year make the next search much easier.

Frequently asked questions
Is it awkward to message someone I haven't talked to in years?
Less than you'd think, if the message is specific and doesn't open with a request. Mention a shared memory or something recent on their profile and ask a simple question about them. Most people are glad to hear from a former colleague.
Should I tell them I'm job hunting in the first message?
Usually not. Restart the conversation first, then share your search once they reply. Exceptions are close former managers or contacts who have posted that their team is hiring, where a light mention up front is reasonable.
How many old connections should I contact at once?
Work in small batches you can actually follow up with, for example five to ten a week. Replies need thoughtful, timely answers, and that's hard if you message a hundred people at once.
What if they don't reply at all?
Send one short follow-up after one to two weeks. If there's still no answer, stop. You can reach out again months later if you have a new, genuine reason.
Can I ask an old connection for a referral?
Yes, if they know your work or you've rebuilt enough rapport to make it comfortable. Ask for one specific role, include the posting and a short summary they can forward, and give them an easy way to say no.
