Why PS Works

Eye‑tracking studies and inbox behavior show readers scan: subject → first line → scroll → PS. That makes your PS a second chance to spark action—without sounding pushy. Done right, it:

  • reinforces the key benefit in plainer words,

  • offers a low‑friction next step (or alternate step),

  • personalizes with a micro‑proof or resource.

Rule: the PS should stand alone. If a skim‑reader sees only the PS, they still know why, what, and how.

How to Use a PS (quick rules)

  • Keep it one sentence (max ~18 words).

  • Offer a different path than the main CTA: lighter, safer, or asynchronous.

  • Mirror the trigger you used (funding, hiring, tool switch, audit, season).

  • Add specificity (timeframe, metric, role) to avoid sounding generic.

  • One PS per email—no PPS, PPPS clutter.

  • Position: last line, after your name/sign‑off.

  • Links: 0–1. Plain, descriptive anchor text beats bare URLs.

25 Copy‑Ready PS Lines (swap tokens and ship)

Organized by common personas/triggers. Replace {tokens} and keep the cadence natural.

A) Growth / Product (PLG SaaS)

  1. PS: If activation is still ~{percent}%, here’s the 2‑week checklist we used to hit {target}.

  2. PS: Short loom? I can mark the two friction points we saw in your flow.

  3. PS: If you’re mid‑OKR planning, this template turns product usage into a weekly activation target.

B) RevOps / Sales Ops

  1. PS: If forecast variance >{percent}%, I’ll send the cost‑driver model teams use to steady it in two cycles.

  2. PS: Prefer numbers? Happy to share the field/flow map that cut report time 50% here.

  3. PS: If HubSpot→Salesforce is in flight, I’ve got a 60‑min migration checklist you can copy.

C) Finance / FinOps

  1. PS: If Q4 budgets lock next week, I can send a one‑pager you can paste into the pack.

  2. PS: Happy to share a 3‑line email your CFO can forward if it helps speed the pilot.

  3. PS: If cloud spend swings >{percent}%, want the tracker tab we use for variance?

D) HR / People Ops

  1. PS: If you’re hiring {count} roles, I’ll share a 4‑day onboarding plan you can tweak.

  2. PS: Remote team? I can send the access checklist that keeps day‑one clean.

  3. PS: If early attrition’s a theme, I’ll pass along three bump lines managers can use post‑offer.

E) Security / IT (plain English)

  1. PS: If your IT lead wants a summary, I’ve got a one‑page “how we handle data” you can forward.

  2. PS: Prefer a quick tech Q&A? I can loop in our engineer for a 15‑minute call.

  3. PS: If you need a simple diagram, I’ll send the data‑flow sketch we give buyers.

F) Marketing

  1. PS: If launches stack in {month}, I’ll share a 2‑week promo plan other teams used.

  2. PS: Want the subject‑line kit we mentioned? It’s 20 fill‑ins you can paste today.

  3. PS: If you’re switching tools, I’ll send the tagging plan that avoids broken reports.

G) Operations / CX

  1. PS: If ticket backlog’s the blocker, I can send a 5‑step triage flow you can test Monday.

  2. PS: Holiday surge coming? I’ll share the VIP routing rule that cut response times to under an hour.

  3. PS: If returns spike post‑launch, I’ve got a tiny SOP you can hand to agents.

H) Executive / Founder

  1. PS: If you just raised, I’ll send the 30‑60‑90 pilot plan we see work post‑round.

  2. PS: No time for calls? I’ll email a 60‑sec Loom so you can see the shape.

  3. PS: If you’d rather start tiny, we can run a 2‑week pilot and credit the fee.

Wildcard (timely / seasonal)

  1. PS: If budgets reset in {month}, I can pencil a pilot that lands results before quarter‑end.

Placement Examples (before/after)

Before (meh):

PS: Let me know if you’re interested.

After (useful):

PS: If activation’s still ~24%, here’s the 2‑week checklist we used to hit 35%.

Before (pushy):

PS: Book time now while slots last!

After (safer path):

PS: No time for a call? I’ll send a 60‑sec Loom so you can see the shape.

A/B Tips (so it actually lifts replies)

  • Test with vs. without PS first; then test resource vs. meeting PS.

  • Keep the body identical; change only the PS.

  • Sample size: 100–300 per variant; judge by reply rate, not opens.
