The Complete Overview of How to Write P.S. in an Email
The P.S. in emails is a relic of analog communication, repurposed for the digital age with surprising adaptability. Unlike formal letters, where postscripts were often used for last-minute additions or personal asides, emails demand a more calculated approach. The digital medium compresses context, so every word—including those in the P.S.—must earn its place. The key distinction is intent: in print, a P.S. might add a personal touch; in email, it often serves a functional purpose, such as reinforcing a call to action, softening a rejection, or injecting urgency. The rules are flexible, but the principles remain: clarity, relevance, and restraint. What separates a masterful P.S. from a misfire? Context. A P.S. in a follow-up email to a client might emphasize next steps, while one in a casual team message could lighten the mood. The same applies to tone: a P.S. in a formal proposal should mirror the email’s professionalism, whereas one in a brainstorming thread might lean into humor or creativity. The art lies in aligning the P.S. with the email’s purpose without disrupting its flow. When done right, it’s a silent upgrade to your communication—when done wrong, it’s a distraction.Historical Background and Evolution
The postscript’s origins trace back to ancient Rome, where scribes added notes (*post scriptum*, meaning "written after") to letters after sealing them. By the 18th century, it became a staple in personal correspondence, often used for intimate or urgent messages. The Industrial Revolution popularized mass mailings, and the P.S. evolved into a marketing tool—companies used it to highlight discounts or deadlines. With the rise of typewriters, postscripts became less frequent, as they required manual addition after the main text was set. Then came email, which revived the P.S. but stripped it of its physical constraints. No longer bound by paper or ink, it could be edited, moved, or deleted with ease—yet its psychological power remained. Email’s democratization in the 1990s turned the P.S. into a double-edged sword. On one hand, it became a crutch for lazy writing—senders would dump secondary thoughts into a P.S. to avoid restructuring their message. On the other, it emerged as a subtle art form, used by savvy communicators to add depth without overloading the main body. The shift from formal letters to casual emails also blurred the lines between professional and personal. Today, the P.S. in emails serves multiple roles: it can be a reminder, a teaser, a joke, or a strategic nudge. Its versatility is its strength—but also its pitfall, as overuse dilutes its impact.Core Mechanisms: How It Works
The P.S. works because it violates expectations. In a linear email, the reader assumes the message is complete—until they see a P.S. at the bottom. This disruption creates a micro-moment of engagement. Neuroscientifically, it triggers the brain’s curiosity gap: the P.S. acts as a "hook," prompting the reader to revisit the email with fresh eyes. Studies on attention spans show that people often skim emails, so a P.S. can serve as an anchor, pulling them back to a critical detail they might have missed. The mechanism is simple: contrast. The P.S. stands out visually (bolded, separated, or indented) and semantically (it’s an "addendum," not part of the core argument). Yet, its effectiveness hinges on placement and phrasing. A P.S. buried in a wall of text loses its punch; one at the very end feels abrupt. The ideal position is just below the signature, where it’s visible but not intrusive. Phrasing matters too: vague P.S.s ("Let me know!") weaken the message, while specific ones ("I’ve attached the revised draft—let’s sync by EOD") drive action. The best P.S.s are concise, actionable, and aligned with the email’s primary goal. They don’t introduce new topics; they reinforce or pivot on existing ones. Think of it as a final brushstroke on a painting—subtle, but transformative.Key Benefits and Crucial Impact
The P.S. is a low-effort, high-reward tool in professional communication. It costs almost nothing to add but can significantly boost response rates, clarify intent, or humanize a transactional exchange. In a world where emails are often skimmed, a well-crafted P.S. ensures your key message isn’t overlooked. It’s also a psychological lever: by adding a P.S., you signal that your email isn’t complete—inviting the reader to engage further. This works particularly well in sales, where a P.S. can include a limited-time offer or a question designed to spark a reply. Even in internal communications, a P.S. can reinforce deadlines or acknowledge a colleague’s effort, fostering goodwill. The impact extends beyond practicality. A P.S. can soften a blunt refusal, add warmth to a formal request, or inject humor into a tense discussion. It’s a way to show personality without overstepping—critical in remote work, where tone is easily misinterpreted. For example, a P.S. like *"P.S. Don’t forget to take a lunch break—your inbox can wait!"* turns a mundane reminder into a moment of connection. The challenge is balancing professionalism with approachability. Done well, the P.S. bridges the gap between corporate detachment and human interaction."An email without a P.S. is like a joke without a punchline—it might be clever, but it doesn’t land." — Emily Post (modern adaptation)
Major Advantages
- Reinforces Key Points: A P.S. can highlight a critical detail buried in the email’s body, ensuring it’s not missed during a quick scan.
- Drives Action: By including a clear call to action (e.g., "P.S. Reply by Friday to confirm"), you increase the likelihood of a response.
- Adds Personality: A lighthearted or thoughtful P.S. can make a formal email feel more human, improving recipient engagement.
- Softens Tough Messages: Useful for declines or feedback, a P.S. can mitigate negativity (e.g., "P.S. Thanks for your time—I appreciate your work.").
- Flexibility in Tone: Unlike the main email, which must adhere to a formal or casual tone, a P.S. can pivot (e.g., a serious email with a playful P.S.).
Comparative Analysis

| Often personal or emotional (e.g., "Love, [Name]"). | Functional or strategic (e.g., "P.S. Attached is the data you requested."). |
| Less constrained by length—can be lengthy or poetic. | Must be concise; brevity is key to avoid distraction. |
| Used for last-minute additions (e.g., "Forgot to mention: the party’s at 7 PM."). | Used for reinforcement or teasing (e.g., "P.S. Stay tuned for Part 2 next week."). |
| Tone is often warmer, more intimate. | Tone must align with professional norms unless the context allows informality. |
Future Trends and Innovations
As email evolves, so will the P.S. The rise of AI-driven drafting tools may make postscripts more standardized—imagine an algorithm suggesting a P.S. based on the email’s tone or purpose. However, the human element will remain critical. Future P.S.s might incorporate interactive elements, such as embedded links or dynamic content (e.g., "P.S. Here’s your personalized discount—[click here]"). Voice assistants could also play a role, with P.S.s read aloud in audio emails to emphasize urgency. Meanwhile, cultural shifts toward brevity (thanks to platforms like Twitter and LinkedIn) may shorten P.S.s further, turning them into micro-messages—single phrases designed to provoke a reaction. The biggest challenge will be balancing automation with authenticity. A P.S. generated by an AI risks feeling impersonal, undermining the very warmth it’s meant to add. The future of how to write P.S. in an email may lie in hybrid approaches: using AI to suggest P.S. templates while allowing humans to customize them for tone and context. As remote work grows, P.S.s could also become more collaborative, with teams co-authoring them to reinforce company culture. One thing is certain: the P.S. isn’t going away. It’s too useful—and too human—a tool to disappear.
Conclusion
The P.S. in emails is a testament to how small details can make a big difference. It’s not about adding fluff; it’s about adding *purpose*. Whether you’re closing a deal, giving feedback, or just checking in, a well-placed P.S. can elevate your message from forgettable to impactful. The key is intentionality: every P.S. should serve a function, whether it’s reinforcing a point, softening a tone, or sparking a conversation. Overuse dilutes its power, but strategic use makes it indispensable. Next time you draft an email, ask yourself: *What’s the one thing I want the reader to remember?* The answer might just belong in the P.S.Comprehensive FAQs
Q: Should I always include a P.S. in every email?
A: No. Only use a P.S. when it adds value—such as reinforcing a key point, driving action, or injecting personality. Forcing a P.S. into every email can make it feel forced or irrelevant.
Q: How long should a P.S. be?
A: Ideally, one sentence or a short phrase. Long P.S.s risk distracting from the main message. If you have more to say, consider restructuring the email’s body.
Q: Can a P.S. be used in formal emails?
A: Yes, but it must align with the email’s tone. In formal settings, keep it professional (e.g., "P.S. Let me know if you need further clarification."). Avoid humor or overly casual language.
Q: What’s the best way to format a P.S. in an email?
A: Start it on a new line, indent it slightly, and use bold or a larger font for visibility. Example:
Best,
[Your Name]
**P.S.** Don’t forget to RSVP by Friday.
Q: Is it okay to use multiple P.S.s (e.g., P.P.S.)?
A: Generally, no. Multiple postscripts can make the email feel cluttered. If you have two points to emphasize, integrate them into the main body or use one strong P.S.
Q: How can I make my P.S. more engaging?
A: Use active language, ask a question, or add a touch of personality (e.g., "P.S. Coffee’s on me if you make this deadline!" for a team email). Avoid vague statements like "Let me know!"—be specific.
Q: What’s the worst mistake when writing a P.S.?
A: Adding irrelevant or off-topic information. A P.S. should complement the email’s purpose, not introduce new subjects. Also, avoid overusing it in cold emails—it can come across as insincere.
