Moving forward, staying connected [optional: linkedin/contact details]
Type: Networking, Forward-Looking, Friendly
Many professionals end roles but carry relationships onward. Including “LinkedIn” or contact details signals an open door. And there is nothing wrong with that.
In fact, I’m still in touch with most of my former colleagues and use those connections to promote my new employer’s products. 🙂
Merry christmas, and a year-end thank you from our team
Type: Appreciation, Relationship, Corporate, B2B or B2C
Who feels like just another contact in a CRM? No one. This subject line works when you want to step out of the transaction loop and land on the relationship.
For service companies, SaaS platforms, or even HR teams, ending the year with thanks shows genuine care.
Christmas Email Example:
Hi [First Name],
Just wanted to send a note as the year wraps up.
Working with you made our days brighter. If you need help over the holidays, check our support schedule below.
We hope your Christmas is restful, and here’s to more shared success in [Year]!
Take care,
[Company Team]
Introduction from [mutual connection or company]
Type: Professional Networking, Outreach
Tone: Warm, Slightly Formal
Use this cold email subject line when you have a mutual connection. It establishes trust by referencing a mutual contact, event, or organization.
Even if you don’t have a direct connection, referencing a well-known company can have the same effect.
Know someone brilliant? Our tech team needs your insight
Type: Referral, Tech Networking
Tone: Warm, respectful
Referrals run deep in tech circles. This subject line values the recipient’s judgment.
Rather than broadcasting job openings, it gently crowdsources talent, creating a ripple effect.
[job title] application after [event or webinar name]
Type: Job Application, Networking
Tone: Contextual, friendly
This can work well if a candidate met a hiring manager during a conference session, community meetup, or online webinar.
It refreshes the recruiter memory, in a helpful way.
Exploring [job title] opportunities with [company name]
Type: Networking, Job inquiry
Tone: Warm, curious
A recruiter often feels the difference between a hard demand and a thoughtful approach
This job inquiry email subject line leans into curiosity and signals that you understand a conversation might explore different options, not just one vacancy.
The wording suits outreach to a talent acquisition partner, a senior leader, or a former colleague who joined [Company Name] recently.
Scheduling a virtual coffee chat on [day]?
Type: Internal, Peer to peer, Remote teams
Tone: Warm, clear, straightforward
Remote teams rely heavily on strong subject lines, because casual hallway chats do not exist.
Use this for internal mentoring programs, onboarding buddies, or cross-functional syncs between support, success, and product teams.
The email can stay short, with one or two sentences about why the chat matters now.
[first name], open to a short coffee chat next week?
Type: Warm outreach, Follow up, Relationship building
Tone: Friendly, conversational, confident
A personalized coffee chat email subject line like this one works when there is already some contact. For example, you could reference a past project, a shared Slack community, or a previous event.
Use this after a positive meeting, after a hiring process that paused, or after a shared panel.
Exploring internship options with [company name]
Type: Internship, Inquiry, Networking
Tone: Friendly, open-ended
This subject can help you when you have general interest in a brand, maybe after an event, a campus talk, or a recommendation from a mentor.
By expressing your curiosity and flexibility, you encourage the reader to suggest various internship opportunities, including ones that never made it to a job board.
Inquiry about internship opportunities at [company name]
Type: Internship, Inquiry, Networking
Tone: Polite, curious, professional
This type of inquiry works well when a formal posting does not yet exist or when you have a referral and want to start a more open conversation.
Wrapping up at [company name] today, staying connected
Type: Farewell, Networking, Update
Tone: Calm, optimistic
Last working day email subject lines often need to carry a sense of closure without feeling final. This version strikes a balance between “wrapping up” and “staying connected.”
Farewell from [your name], keeping in touch after [company name]
Type: Farewell, Relationship, Networking
Tone: Friendly, open
Many farewell subject lines feel stiff. This one leans slightly more personal, but doesn’t cross the line into casual slang. This tone suits professional environments, such as support, product, or operations teams.
Great to connect at [event name], a short introduction
Type: Networking, Event follow up
Tone: Friendly, informal professional
When someone sees the event name, they will remember it faster, and your message will stand out from generic sales outreach.
Pair this subject line with an email that reminds the reader of a specific part of an earlier conversation and proposes a specific next step.
Really enjoyed your take on [Topic] at [Event/Panel]
Type: Speaker Follow-Up / Warm Intro
Tone: Grateful, specific
Flattery works best when it’s genuine and specific. If someone shared an insight that stuck with you during a panel, webinar, or roundtable, say so.
This subject line works because it feels like a compliment, not a sales pitch.
We missed each other at [Event], want to connect anyway?
Type: Missed Connection
Tone: Friendly, forward
Events are chaos. You plan to meet someone, but it never happens.
This subject line gives you a second chance.
Quick question: coffee next Tuesday?
Type: Networking / Personal Outreach
Tone: Friendly, informal
Short, social, and time‑bound. This subject line feels like text from a friend, which cuts through sterile inbox noise.
This Subject Line Can Also Be:
- Quick question: latte or espresso?
- Quick question on meeting up Tuesday
Saw your post on [Platform], had to reach out
Type: Cold Outreach
Tone: Curious, conversational
When you reference a real post on LinkedIn or X (formerly Twitter), it shows you’ve paid attention. The phrase “had to reach out” carries emotional urgency.
It’s best to use it within 24–48 hours of the post to maintain context.
In the email, mention one detail from the post, share your perspective or ask a question, and invite a quick chat if they’re open to it.
This approach works well for community builders, consultants, and early-stage founders.
Are you the right person to chat with about [Topic]?
Type: Polite Cold Outreach
Tone: Direct, respectful
Sometimes you don’t know who the decision-maker is. That’s fine. This subject line eliminates the need for guesswork and puts the power in the hands of the reader.
Mind if I share a quick idea about [Problem/Topic]?
Type: Light Touch / Soft Ask
Tone: Humble, open-ended
This subject line builds trust quickly. You’re not pushing an offer, you’re offering a thought, and asking for permission first. That’s rare in a crowded inbox.
Quick hello from [Event] yesterday
Type: Event Follow-Up
Tone: Friendly, professional
Anchor the reader’s memory with a fresh event and show interest. A date cue and “hello” signal warmth without hype.
Send the email within 24 hours after first meet. Reference the panel or the chat at the snack table, and then offer one clear next step. Keep the preview text short so the subject retains the spotlight.
Mutual connection [Referrer Name] suggested we chat
Type: Referral Introduction
Tone: Warm, credible
Mentioning a trusted referrer establishes instant social proof, and segmentation pays off.
However, keep it honest; misusing a name torpedoes trust quickly.
Referral Email Example
Hi [Name],
[Referrer Name] mentioned you are exploring AI-driven support workflows.
I have helped several SaaS teams streamline similar rollouts and would love to swap lessons.
Are you free this Thursday at 3 pm IST?
Cheers,
[Your Name]
Bringing [Shared Interest] ideas to your inbox
Type: Value Share / Thought Leadership
Tone: Curious, helpful
People open emails that promise concrete value.
By naming one interest that you both identified, such as “low-code CX” or “green retail operations,” you demonstrate relevance and boost those coveted email metrics.
Inside the email, provide one or two concise insights, a link, and a low-pressure invitation to continue the conversation.
See who’s attending [EventName]
People want to know who else is going, this subject line taps curiosity
If the audience includes known figures or peers, readers want in. This one performs well in B2B meetups and industry summits.
Type: Networking / Industry Events
Tone: Curious, social
Goodbye Team, Hello New Adventure
Tone: Upbeat, Brief
By greeting and parting in one breath, you keep the reader engaged. The adventure hook often triggers replies filled with encouragement, which can lead to future networking opportunities.
Quick Tips
- Add a one‑sentence mission for your next role, inviting feedback.
- Link to your personal blog if you’ll chronicle the journey.
Loved your [Topic] piece, could I add a fresh angle?
“Loved” and “[topic] piece” appear together, indicating genuine reading rather than blanket spam. Then, you quickly pivot to “fresh angle,” hinting at novelty.
Send your email with this kind of subject line within 48 hours of their article going live while the excitement is still fresh.
Avoid weekends because holiday noise buries nuance.
Tips
- Quote a line from the post inside to prove you read it.
- Offer a data point they missed. Editors crave fresh angles.
Type
Warm Outreach, Relationship‑Based
Tone
Respectful, collaborative, warm
Could you refer me to [Company], please?
When you ask outright for a referral, clarity trumps cleverness. This referral email subject line makes the request obvious, so your contact never wonders what you need.
I add please because courtesy keeps doors open, even when time runs tight.
By naming the target (company in brackets), you help the reader visualize the task and feel capable.
Use this subject line when you already enjoy a warm rapport and want a swift response.
Type: Professional, Networking
Tone: Polite, Direct
Email example:
Hey [Name],
Hope your week rolls along smoothly.
I’m exploring an opportunity at [Company] and heard you know the hiring team.
Would you feel comfortable putting in a kind word or passing along my résumé?
Happy to share any context you need.
Quick favor, [Name], can you introduce us?
Type: Relationship, Personal
Tone: Friendly, Conversational
This referral email subject line leans on the lightweight “quick favor” framing.
Respect for the reader’s inbox and hints the lift will be small. Most marketers rely on personal introductions to nurture leads throughout retention journeys.
Starting with the recipient’s name personalizes the ask.
Use this subject line when time feels scarce, and you need the referral wrapped into a brief intro thread.
[Name], who in your circle needs this?
Type: Networking, Personal Connection
Tone: Conversational, Curious
Use this email subject line when you want a softer, curiosity-driven intro that feels more like a friendly nudge than a straight-up ask.
The idea is to spark the reader’s mental Rolodex by mentioning “your circle,” which often means friends, clients, or colleagues.
Using the recipient’s name personalizes the request and, honestly, makes the email feel less like a broadcast.
I suggest using this kind of referral subject lines when you have a good relationship with the contact and want them to consider referring someone without pressure.
Just wanted to say thanks again, [First Name]
Tone
Casual, friendly, warm
Why It Works
This one’s softer, more conversational. The phrase “just wanted to” creates a gentle tone and avoids sounding overly formal. It’s useful after a helpful interaction, support resolution, or even an informal favor.
The “again” implies this isn’t the first time you’ve said it, which adds depth to the appreciation. And when used in a post-support or customer success context, it leaves the door open to future interactions.
This format pairs well with plain-text emails. No hard CTAs. No friction. Just kindness, which most inboxes don’t get enough of.
This Subject Line Can Also Be:
- Thanks again for everything, [First Name]
- Appreciate you helping out today
Hey [First Name], just wanted to say thanks
Type:
Casual, One-on-One, Relationship Building
Tone:
Conversational, friendly, and personal.
Why I Chose This Subject Line:
This feels like something I’d write to a colleague or client I genuinely like. That’s why it works.
It’s not formal, but it’s not sloppy either. The casual tone helps break the corporate wall.
Great for relationship-based businesses, small teams, or account managers.
Tips:
- Use the name field accurately. If your system can’t personalize reliably, skip this line.
- Don’t bury the message. If you say thanks, explain why. One or two lines is fine.
- Sign off like a real person. Even in a brand email, add a name at the bottom.
Example Email:
Hey [First Name],
I was just thinking about our call earlier. Just wanted to say thanks for your time, your input, and your trust.
Looking forward to what’s next.
– [Your Name]
[Name], just circling back on my last email
Type
Networking, Professional Follow-Up
Tone
Polite persistence
Why this line works
Beginning with the recipient’s name boosts personalization.
“Circling back” signals continuity without sounding accusatory.
Use active verbs, put the subject’s name first, and avoid passive filler.
This subject line is ideal for sales reps, recruiters, and project leads who want to provide an update while maintaining goodwill.
Possible misunderstandings
- Avoid overuse. Weekly repetition can feel spammy.
- If the previous email carried no clear ask, clarify that inside this follow-up.
Example email
Hi [Name],
I didn’t want my last note to slip through the cracks. Do you have five minutes this week to talk through next steps?
Your feedback helps shape the roadmap. I respect your schedule, so choose a time that works for you.
Thanks a ton,
Lee
