Reconnect Email Subject Lines That Actually Get Opened
The best reconnect email subject line names something you share, like a person, a place or a project. Then they know you before they open it. Try "Still thinking about the Denver launch" or "[Mutual contact] said to say hello" as a start. Keep it to eight words or fewer. Skip vague lines like "Long time no see" in the subject. Make sure the email keeps the subject's promise.
A reconnect email is often the easiest way to revive a bond that already has trust built in. The person knows your work. The subject line decides if they remember that before they hit delete. So it has to point to something you share.
What makes it land is being specific with no pressure. Name the project, the person or the city. Keep the first note about them, not what you sell. If the email feels like it could only come from you, it usually gets a reply.

Everyone on a rhythm. Who is due, and when. Recorded in the app on a demo account.
1. After two years of silence, no ask
Subject: Thought of you at [specific detail]
Why it works: A real memory in the subject and first line proves it's personal. Saying there's no agenda removes any reason to hold back.
2. Reaching out to a former boss
Subject: Still using what you taught me
Why it works: Former managers rarely hear how their coaching paid off. So specific thanks is both flattering and memorable.
3. Through a mutual contact
Subject: [Mutual contact] says hello
Why it works: A familiar name in the subject line earns the open right away. The shared story gives the email warmth.
4. Congratulating them on big news
Subject: Congrats on the [new role / milestone]
Why it works: News gives you a natural reason to write. Tying the congrats to their past work shows you paid attention.
5. Sharing something useful
Subject: Saw this and thought of you
Why it works: Leading with something useful helps them even if they never reply. That makes a reply more likely.
6. You changed roles and want them to know
Subject: New chapter, and I thought of you
Why it works: Your own news gives the email a clear purpose. Saying why they came to mind keeps it from feeling like a mass note.
7. Honest about the long gap
Subject: Overdue hello from [Your Name]
Why it works: Owning the silence in one line feels human. The shared memory quickly turns the focus back to the bond.
8. Reconnecting when you need advice
Subject: Quick question about [specific topic]
Why it works: Being upfront about a small, clear ask and giving an easy out respects their time and their judgment.
9. Visiting their city or attending the same event
Subject: In [City] next week, coffee?
Why it works: A real deadline and a clear plan make it easy to say yes. Offering to come to them lowers the effort.
10. Reconnecting with a former client
Subject: Remembering the [project name] rollout
Why it works: Asking about results from shared work shows real interest in their success. Saying no pitch keeps their guard down.

When to send it
- Send it within a week of a natural trigger. That could be their promotion, company news or a friend in common saying their name.
- Send it Tuesday through Thursday mornings in their time zone. Inboxes are lighter then than on Monday.
- Reach out two to three weeks before you need anything. Then the reconnect doesn't read as a favor in disguise.
- Avoid their known busy seasons, such as year-end for fundraisers or quarter close for salespeople.
- If you'll be in their city or at the same event, write ten days to two weeks ahead so they can plan.
Subject lines
- Thought of you at [event]
- [Mutual contact] said to say hello
- Still using what you taught me
- Congrats on the new role at [Company]
- Overdue hello from [Your Name]
- Remember the [project name] crunch?
- Saw this and thought of you
- From one [Company] alum to another
- In [City] next week, coffee?
- A quick update, and a question
- It's been too long since [shared place]
- Your advice on [topic] paid off
- Quick question about [topic]
- Picking up where we left off
- Long overdue, [Name]
What to avoid
- Don't use "Long time no see" or a lone "Hi" as your subject line. It gives the reader no reason to know you.
- Don't lead with a sales pitch or a big favor in the first note after years of silence.
- Don't say sorry too much for the gap. One honest line is enough, and more makes it awkward.
- Don't write a subject the email doesn't deliver on, like "Quick question" with no question inside.
- Don't send a generic note that could go to anyone. One shared detail does more than three paragraphs.
- Don't add a fake "Re:" to make it look like an old thread. It breaks trust the moment they notice.
After you send it
If you don't hear back in a week to ten days, send one short follow-up in the same thread. Add a new detail or an easy way to reply, like a specific time for a call. If there's still nothing, let it rest. Try again in a few months with a fresh reason. Once you reconnect, stay in touch every two to three months with something useful. Send an intro, an article or a congrats. Small, regular notes mean you won't need another reconnect email.

Frequently asked questions
What is a good subject line for a connection email?
A good one is short and names something they will know. That could be a friend in common, a shared employer, an event or a specific project. "[Mutual contact] suggested I reach out" is one example, and "Fellow [Company] alum here" is another. Aim for six to eight words. Avoid all caps and hype. Make sure the email body matches what the subject promises.
How do I reintroduce myself in an email?
Reintroduce yourself in the first two sentences. Remind them where you met and what you shared. For example: "We worked together on the [project] launch at [Company] in 2019." Then give a one-line update. Say what you do now and why you're writing. Close with an easy next step, like a short call. Keep the whole email under 150 words.
How do I reconnect an email?
Open with a real shared memory or a true reason you thought of them. Give a short update about yourself and ask about them. Then suggest an easy next step. Skip the long apology for the gap. If you need something, say so plainly. But in most cases, your first note should just restart the talk.
How do I reply to an email with a new subject line?
Reply as usual, then edit the subject field before sending. Swap the old subject for one that names the new topic, such as "New topic: [subject]" or "Update on [project]". Changing the subject starts a fresh thread in many inboxes. If the context matters, keep the old messages quoted below. Or mention the earlier talk in your first line.
Should I mention how long it's been since we talked?
Yes, but briefly. One honest line such as "It's been too long since we talked" admits the gap and moves on. Long apologies make the email about your guilt, not the bond. Most people are glad to hear from a former colleague. They won't hold the silence against you, especially if you lead with something specific and warm.
