How to Say "Long Time No See" in a Professional Email
To say "long time no see" in a professional email, name the gap in one plain line. Try "It's been a while since we worked on [project]." Then give one real, current reason you're writing. Note the silence without apologizing for it. Make the email about them, not your need. Keep it under 120 words, with one easy question or no ask at all.
A reconnect email decides if an old tie becomes useful again or stays asleep. Most people are glad to hear from someone they liked working with. What they don't want is a sales pitch dressed up as a hello. Your first email after a gap shows which one you are.
What makes it land is a detail only you would know, like a project, a talk or a result. That detail proves you remember them as a person. Pair it with a short, honest reason for writing now. Add a question that's easy to answer. The reply usually follows.

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: It's been a while, [Name]
Why it works: A specific memory with no ask makes the email feel generous and easy to answer.
2. After seeing their news (promotion, launch, funding)
Subject: Congrats on [news]
Why it works: Their own news gives you a natural, timely reason to write that's all about them.
3. Former colleague, after you changed roles
Subject: A quick update (and hello)
Why it works: Your update gives them context, and praising their strength keeps the focus on them.
4. Past client you'd like to work with again
Subject: Thinking about [project] at [Company]
Why it works: Asking about past results and offering lessons with no strings reopens the door without a hard pitch.
5. Lapsed donor or supporter, gratitude first
Subject: What your support made possible
Why it works: Showing a past supporter what their gift did rebuilds trust before any future ask.
6. Recruiter reconnecting with a past candidate
Subject: A role that made me think of you
Why it works: Remembering what they said they wanted proves this is personal, not a mass email.
7. You'll be in their city or at the same event
Subject: In [City] on [date]?
Why it works: A real date and place turn a vague reconnect into an easy yes or no.
8. Sharing something useful for their work
Subject: Saw this and thought of you
Why it works: Leading with something useful makes your email a gift, not a request.
9. Asking for advice after a long gap
Subject: Could I ask your advice?
Why it works: Naming the gap honestly and offering a smaller backup ask makes it easy for them to help.
10. Formal version for a senior contact you met once
Subject: Following up from [event], [year]
Why it works: A clear reintroduction and a sincere thank you respect a senior person's time and memory.
11. When you were the one who went quiet
Subject: Picking up where we left off
Why it works: A short, honest apology for a dropped thread clears the air without groveling.

When to send it
- Send within a day or two of a real trigger. That could be their promotion, company news, a mutual contact naming them, or an article they'd like.
- Reach out at least a few weeks before you need anything. Then your first email after the gap isn't an ask.
- Send Tuesday through Thursday, mid-morning in their time zone. If they work in sales or finance, skip the last week of a quarter.
- If the gap is over a year, send a no-ask hello first. Save any request for your second or third exchange.
- Skip major holidays and the first Monday back after vacation season, when inboxes are buried.
Subject lines
- It's been a while, [Name]
- Long time no see
- Congrats on [news]
- A quick hello from [Your Name]
- Thinking of you and [project]
- Saw this and thought of you
- In [City] on [date]?
- A quick update (and hello)
- Following up from [event], [year]
- Picking up where we left off
- Could I ask your advice?
- What your support made possible
- A role that made me think of you
- Remember [shared project]?
- Hello from your old [Company] colleague
- Coffee next time I'm in [City]?
What to avoid
- Don't open with a long apology for the gap. It makes the email about your guilt, not the relationship.
- Don't make your first email after years of silence a sales pitch or a favor request.
- Don't send a generic note that could go to anyone. Include one specific shared detail.
- Don't assume they remember you. Add a one-line reminder of where and how you met.
- Don't write more than one short screen. A long reconnect email feels like homework.
- Don't use a vague subject like "Hi" or "Quick question" that looks like spam. Someone who hasn't heard from you in years will skip it.
After you send it
If you don't hear back, wait about a week. Then reply in the same thread with one short line, like "Bumping this up in case it got buried. No pressure either way." If there's still no reply, let it rest. Try again in a few months with a new reason. Once they respond, keep the thread alive. Reach out every two to three months with news, a useful link or a congrats. Suggest a call or coffee at least once a year.

Frequently asked questions
Is "long time no see" appropriate in a professional email?
Yes, with people you know and get along with. It reads as warm and casual. Some cases call for more polish: senior contacts, people you met once, or very formal fields. There, use "It's been a while since we last spoke" or "It has been some time since we met at [event]" instead.
What can I say instead of "long time no see" in a business email?
Try "It's been a while since we last connected" or "It's been too long" as an opener. "I was thinking about our work on [project]" and "It has been some time since [event]" also work. The best option ties the gap to a specific memory. That shows you remember them and gives them something real to respond to.
Can I combine "long time no see" with "I hope this email finds you well"?
You can, but that's two stock phrases before you've said anything real. Pick one short opener. Then move straight to a specific detail or your reason for writing. A line like "It's been a while, and I thought of you when [detail]" does more than both phrases. It also sounds like you wrote it yourself.
How do I start an email to someone I haven't talked to in years?
Start by reminding them who you are and where you met, in one line. Then share why you're thinking of them now. Put context first, then warmth, then a light question. For example: "We worked on the [project] launch at [Company] in [year]. Your news about [detail] made me want to say hello."
Should I explain why I haven't been in touch?
Usually no. Most work ties go quiet on their own, and both sides know it. Name the gap briefly and move on. The exception is when you left something unfinished, like an unanswered email or a promised intro. Then a one-line apology is right. Follow it with the conversation you want to restart.
