Sneak peek, early access to our new collection
Type: VIP / Loyalty
Tone: Exclusive and conversational
This new arrival email subject line uses “sneak peek” to signal a backstage pass. “Early access” adds scarcity, making loyal subscribers feel seen.
Use it 24 hours before a public launch. Exclusivity phrases can raise click‑through by 18%. Test it on your segmented VIP list, watch the lift, and then roll wider if engagement spikes.
[Product Name] Is Back in Stock, [Name]!
Tone
Friendly, direct
Why This Works
By putting the customer’s name in the subject line, it feels like a personal note. It feels more like a heads-up from a friend than a mass email.
Tips
- Ensure your merge tag populates correctly, or it can land as “, !” which confuses readers.
- To keep it concise, limit personalization to the first name. Longer merges get truncated on mobile.
Clock’s Ticking, 12 Hours Left to Grab Your Deal
Type
Marketing, Promotional
Tone
Urgent yet friendly
Why It Works
Putting an exact window (12 hours) next to an active verb (“grab”) squeezes decision time. In tests, urgent subject lines lifted opens by roughly 22%. Readers feel they might miss out if they hesitate.
The countdown email subject line also stays short (42 characters), sitting comfortably inside the 50-character sweet spot.
When to Use
- Last-chance sales, flash discounts, time-boxed upgrades.
- Send six to ten hours before the cut-off so the math feels real rather than hypothetical.
Quick Tips
- If your list spans time zones, add a line in the email body that auto-converts the deadline.
- Pair the subject line with a live countdown timer block. Real-time timers push click and conversion rates noticeably higher.
- Personalize the preview line with “Hi [name], stock is melting”.
Example Email
Hey [first-name],
Only 12 hours until the price resets.
Tap the button below, lock your discount, and relax.
Still on board? Enjoy a fresh perk inside
Tone: Encouraging, incentive‑driven, upbeat
Why It Works
“Still on board?” checks loyalty, while “fresh perk” promises immediate value.
The whole subject line stays under 50 characters, which helps mobile previews.
Attach the perk in the email body: a small credit or cheat sheet to justify the open.
When to Use
Great for SaaS renewals or memberships with lapsing engagement.
Tips
- Use merge tags to insert the plan name, e.g., “[Plan] perk just landed.”
- Remind them of unused features to spark curiosity.
Your VIP code inside, [first name]
Why I picked it
I lean on the promise of exclusivity, and I anchor the line with a first-name token because personalized subject lines lift opens by roughly 26%, according to an CampaignMonitor study.
Pair “VIP” with “code” and you hint at savings without clutter. The phrasing stays short, just nine words, which plays nicely on mobile screens.
The mix of curiosity (“inside”) and urgency (“code”) nudges shoppers who skim at speed.

Friendly, exclusive, lightly urgent
Example email
Hey [first name],
You earned VIP status, so I tucked your private 20% code below. It works until midnight.Enjoy shopping.
— [Brand]
Free shipping, ends at midnight
Why I picked it
Most e-commerce shoppers chase free delivery, yet only 31.08% of retail messages get opened on average, per MailerLite’s 2025 benchmarks.
Place the perk first, then a ticking clock. The countdown frame taps that “urgent” cue. It’s a proven hook in promotional lines.
Keeping verbs simple signals clarity and trust, so spam filters stay quiet.

A quick thank-you gift, 15% off today
Why I picked it
Gratitude softens sales talk.
Here I front-load “thank-you” to spark positive emotion, then quantify the perk.
Numbers stand out in crowded inboxes, and they stay readable. Klenty’s research found that open rate can nearly double when a name or pain point feels personal; a genuine thanks builds that same closeness.
I also added “today” to curb procrastination yet keep pressure gentle.

Flash deal, 120 minutes of crazy prices
A two-hour window sounds wildly tight, and that scarcity pushes clicks.
Global averages show only 19.21% of broadcasts get opened, so stacking “flash,” a firm timeframe, and an emotional adjective (“crazy”) can vault you above the norm, based on WebFX 2025 email benchmarks.
I avoid symbols, lean on rhythm, and break the rule of perfect form just a touch, because that imperfection reads human.

High-energy, urgent
This subject line can also be

- 120-minute deal drop, hurry in
Upgrade your workspace, save $50 on Pro Plan
For SaaS, lead with the benefit (“upgrade”) and quantify savings. The specificity sidesteps vague hype, and “Pro Plan” clarifies scope.
Personalized versions lift opens by roughly 22%, so adding a first name token can bump performance further. Because B2B buyers weigh ROI, a direct dollar figure satisfies the analytical side, while “save” strokes the emotional side.

Heads up, prices drop for 24 hours only
You can trust scarcity. Words like “urgent” or “expires” push opens because they spark fear of missing an offer.
I keep the line short, so mobile previews don’t clip the promise. The phrase “24 hours” states a clean deadline, and “heads up” feels conversational, not pushy.
Together, clarity and urgency create a gentle nudge, and clarity also steers clear of spam triggers.

🎁 My gift, your first month free
Emoji experiments keep paying off. A 56% higher open rate when a tiny graphic kicks off a subject line. Pair that symbol with “free,” and add another 10% bump.
This subject line speaks in first person to make the promise feel personal. Positioning the benefit (“first month free”) after the comma keeps the line punchy and transparent, so the offer reads like a no-brainer.
Short, clear, generous—three boxes ticked.

Early access, new collection drops tomorrow
Behavior-triggered sends crush broadcast averages.
This subject line promise exclusivity up front (“early access”) and then confirm the timeline (“tomorrow”).
Shoppers plan wardrobes or wish lists; a clear drop date starts that mental countdown.
No fancy adjectives, no hype. Just timing and privilege, backed by data that shows exclusivity fuels curiosity.

Your Black Friday code just landed
This subject line triggers curiosity by making the discount feel personal and urgent. “Just landed” implies it’s hot off the press, which is perfect for inboxes flooded with generic sales spam.
I used the word “your” deliberately to give the impression that this code was meant only for the recipient.
It also dodges trigger words like “FREE” or “BUY” that spam filters sometimes flag around this season.

BFCM bundle alert, buy 2 get 3 free today
Using “BFCM” instead of spelling out both holiday names can boost opens, as Seguno found subjects with the acronym outperforming “Black Friday” or “Cyber Monday.”
The bundle math (buy two, get three) feels generous yet simple. Readers love quick calculations.
I add “alert” to spark immediacy and end with “today” to cap procrastination.
The structure layers curiosity (bundle), value (free units), and urgency (today) in one breath while staying under 50 characters, so smartwatch users still see the whole promise.
Type

This subject line can also be
- BFCM bundle blow-up, 3 free when you grab 2
- Bundle frenzy, snag 3 freebies now
Final hours, deal ends at 10 PM
You see the countdown right away, and that ticking fear of missing out drives clicks.
I chose 10 PM because specific deadlines outperform vague “soon” promises, especially on mobile where readers skim.
Keep words short, verbs active, and numbers upfront, and you reduce cognitive load.

Why I Chose This
Emojis split opinions, yet Experian found 56 % of brands saw higher opens when adding tiny icons.
I drop the hand-wave emoji first so users spot a friendly cue even in crowded mobile views.
The parenthetical “small gift” sparks curiosity without sounding click-bait.
When to Use
Ideal for ecommerce, freemium apps, or newsletters with a coupon, template, or bonus guide. Send within an hour so the offer feels tied to signup rather than a random promo.
Tips
- A/B test the emoji; some B2B audiences prefer plain text.
- Make the gift obvious in the first line of the email to meet expectations quickly.
