Why This Calendar Works

1. Customer Intent Peaks – Each holiday aligns with predictable buying or gifting behavior.

2. Built‑In Scarcity – Limited shipping windows and holiday deadlines create urgency without deep discounts.

3. Content Balance – Storytelling and gratitude emails keep you out of the promo‑only spam trap.

4. Consistent Touchpoints – Roughly three sends per month hit the sweet spot for small lists (keeps engagement high, unsubscribes low).

Month‑by‑Month Deep Dive

January – “Reset & Refresh”

What to Send:

• Jan 1: Inspirational plain‑text note from the founder with a small loyalty coupon.

• Jan 7: Clearance or “out with the old” collection spotlight.

• Jan 28: Progress‑check nurture (ask how goals are going, recommend add‑on products).

Why: Customers have fresh budgets and self‑improvement mindsets. You position your product as the helper.

February – Love & Loyalty

Emails:

• Early gift guide (Feb 1)

• Urgent “last‑ship” Valentine reminder (Feb 11)

• Post‑holiday “Love Your Customers” thank‑you with user‑generated content (Feb 15)

Pro Tip: Start segmenting by gift buyers vs. self‑purchasers for March upsells.

March – Spring Forward

Combine St. Patrick’s Day fun (green theme, lucky draw) with spring “new collection” hype. Send a spring‑cleaning checklist and tie products to renewal.

April – Family & Earth

Earth Day storytelling is perfect for eco angles and charity tie‑ins. For tax refunds, frame offers as “smart splurge” or “upgrade without guilt.”

May – Moms & Memorial

Mother’s Day campaigns perform best when you offer gift sets and shipping countdown timers. Memorial Day opens peak summer buying—run tiered % off or “buy more save more.”

June – Dads & Outdoors

Test a plain‑text “dad joke” email to cut through inbox clutter. Follow with bundle suggestions (grill kit, tool kit) plus a first‑day‑of‑summer giveaway.

July – Mid‑Summer Momentum

Patriotic color palettes convert, but also send a mid‑summer survey asking subscribers what content or products they want next—goldmine for Q4 planning.

August – Prep & Last Chance

Back‑to‑school isn’t just for kids: position organizers, planners, or health resets. End‑of‑summer “last call” clearance moves old inventory without heavy discounting in Q4.

September – Fall Sneak Peek

Labor Day soft sale followed by a “fall drop” preview. Invite VIPs first, drive FOMO. Showcase behind‑the‑scenes product development stories.

October – Spooky Sales & Q4 Warm‑Up

Run a Halloween limited edition, costume contest, or “treat yourself” deal. End with a teaser for upcoming Black Friday VIP list.

November – Gratitude & Black Week

Sequence to copy:

1. Nov 11 “Holiday Gameplan” early‑bird offer

2. Nov 26 “Thank‑you” story + soft upsell

3. Nov 29 Black Friday doorbuster

4. Nov 30 Small Business Saturday loyalty reward

5. Dec 2 Cyber Monday last‑chance

Keep segments tight—repeat customers get VIP tier, new subscribers get curated bundles.

December – Deadline Drama & Reflection

• Dec 3: Gift guide with shipping cutoffs.

• Dec 16: “Last day for standard shipping.”

• Dec 28: Year‑in‑review and sneak peek at 2026 launches; invite feedback survey.

Tips for Small‑Business Execution

1. Batch Create – Draft three emails at once; schedule inside Klaviyo/Mailchimp.

2. Repurpose Content – Turn one blog into a series teaser + how‑to email.

3. Use Light A/B Tests – Subject line emojis vs. none, 20 % sample, winner to rest.

4. Sync Pop‑Ups to Season – Update hero image and copy every quarter.

5. Segment by Engagement – Send high‑frequency emails only to recent openers; protect deliverability.
