What to Actually Write in Your Marketing Emails (With Examples)

Most email marketing advice is written for large e-commerce brands with dedicated marketing teams, A/B testing budgets, and entire departments devoted to conversion optimization. That advice is not for you. If you're a salon owner squeezing in an email between clients, or a restaurant manager trying to fill seats on a slow Tuesday, you need something simpler and more honest.

Here's the reality of what you're working with: 78% of your emails will be opened on a phone. That means a small screen, a short attention span, and a thumb that's one flick away from deleting everything. The average open rate across industries sits at 43.46%, which is genuinely good news — it means nearly half of your subscribers are giving you a shot every time you hit send.

The question isn't whether email works. It does. The question is what to actually write when you're staring at a blank screen with fifteen minutes before your next appointment. This guide covers the principles behind great small business emails — the same principles Cherub's AI uses when it generates campaigns for you. Whether you're writing your own copy or just want to understand what good looks like when you approve a suggested campaign, this is what matters.

Your subject line is the only thing standing between your email and the trash folder. According to Mailchimp's analysis of billions of sends, the sweet spot is 9 words and no more than 60 characters. That's not a suggestion — it's the point where open rates measurably drop off. Longer than that and your subject line gets cut off on mobile, which is where most of your customers are reading.

Keep your punctuation under control. No more than three punctuation marks in a subject line. Excessive exclamation points don't convey excitement — they convey desperation, and spam filters know it. Personalized subject lines are 26% more likely to be opened, and personalization can be as simple as including someone's first name. Guess saw strong results with "Mary, check out these hand-picked looks" — it's specific, personal, and doesn't try too hard.

What you should absolutely avoid: generic subject lines and fake urgency. The phrase "Touching Base" has a trash rate above 50% — more than half of recipients delete it without opening. And phrases like "Act now!", "Last chance!", and "Don't miss out!" have been so thoroughly abused by marketers that they've lost all meaning. Your customers have seen thousands of "last chances" that weren't actually last chances. They don't believe it anymore.

The impact of getting this right is significant. In one documented case, a single subject line change increased email revenue by 9%. Same email body, same offer, same audience — just a better subject line. These are exactly the rules Cherub's AI follows when it generates subject lines for your campaigns — short, personalized, honest, and tested against billions of data points. You can always edit what Cherub suggests, but now you'll know what "good" looks like.

Preview text is the short line of copy that appears next to or below your subject line in the inbox. On most email clients, it shows 40 to 90 characters depending on the device and how long your subject line is. It's your second chance to convince someone to open, and most small businesses either leave it blank or waste it by repeating the subject line.

When you leave preview text blank, email clients pull in whatever text they find first — usually something like "View this email in your browser" or the alt text from your logo image. That's a wasted opportunity. The key is to complement your subject line, not repeat it. Your subject line makes the promise; your preview text adds a reason to believe it.

Front-load the value in your preview text. The first few words are the only ones guaranteed to show on every device. If your most important information is buried at the end, half your audience will never see it.

Here's what strong pairings look like in practice. For a restaurant: subject line "New weekend brunch menu starts Saturday" paired with preview text "Lavender French toast, smoked salmon benedict, and bottomless mimosas." For a salon: subject line "Spring looks are here, Sarah" with preview text "Balayage, curtain bangs, and the color trend everyone's asking about." For a retail shop: subject line "Fresh arrivals just hit the floor" with preview text "12 new pieces from three local designers — selling fast in-store." In each case, the preview text gives a concrete, specific reason to open that the subject line alone doesn't provide.

The data on email length is clear and somewhat surprising: the optimal email body is 101 to 150 words. That's roughly three short paragraphs. Most business owners write emails that are two to three times too long because they feel like they need to justify sending an email at all. You don't. Your customers signed up because they like your business. They don't need a five-paragraph essay to prove it was worth opening.

Remember that 78% figure from earlier — most of your readers are on their phones. They're scanning, not reading. They might be in line at the grocery store, waiting for a meeting to start, or scrolling during a commercial break. You have maybe ten seconds of their attention. A single clear message with a single clear action is all you need.

The best mental model for small business emails is this: don't write a newsletter — write a note to a friend. If you were texting a regular customer about something happening at your business, you wouldn't write four paragraphs about your brand story and mission statement. You'd say what's happening, why it matters to them, and how to take advantage of it. Do that in your emails and you'll outperform 90% of the marketing emails in their inbox.

Your call-to-action button is where the email either pays off or doesn't. According to Campaign Monitor, placing your primary CTA near the top of your email — visible without scrolling on mobile — significantly increases click-through rates. Don't bury your ask below three paragraphs of preamble. Lead with the action and let the supporting text follow.

The language on your button matters more than most people think. Benefit-driven language outperforms generic language every time. "Reserve Your Table" tells a customer exactly what they're getting. "Click Here" tells them nothing. "Book Your Appointment" is an action with a clear outcome. "Learn More" is vague and passive. The best CTAs describe the result of clicking, not the act of clicking itself.

On the design side, your button needs to be impossible to miss and easy to tap. Use high contrast between the button color and your background — if your email is mostly white, a bold terracotta or deep sage button stands out. And size matters for mobile: Apple's Human Interface Guidelines recommend a minimum 44-pixel tap target, and your email button should be at least that tall. Tiny links and small text buttons frustrate mobile users and suppress your click rate.

Theory is useful, but you came here for something you can actually send. Here are three complete email templates — subject line, preview text, body, and CTA — tailored for the industries that make up most of our users. These are the same kinds of emails Cherub's AI generates for you, pulling in details from your actual product catalog and business context. Adapt them for your business, or let Cherub do it automatically.

There's a playbook that aggressive email marketers have been running for years, and your customers are exhausted by it. These tactics might generate a short-term spike in clicks, but they erode trust with every send — and trust is the only real asset a small business has in its relationship with customers.

Fake urgency and countdown timers. "Only 2 hours left!" when there's no real deadline. "Flash sale ends tonight!" for a sale you run every month. Countdown timers that reset when you reopen the email. Your customers aren't stupid. They notice when the "last chance" comes around again next Tuesday. Every fake deadline makes the next real one less believable.

Artificial scarcity. "Only 3 left in stock!" when you have a warehouse full. "Limited spots available!" for a class that's nowhere near full. Manufactured scarcity is a manipulation tactic, full stop. When you genuinely are running low on something, say so — your customers will believe you because you haven't cried wolf.

Deceptive subject lines. "RE: Your appointment" when there's no existing conversation. "Your order update" when they haven't ordered anything. These might get opened once, but they generate spam complaints and destroy any goodwill you've built. Some of them also violate CAN-SPAM regulations, which is a legal problem on top of a trust problem.

The alternative is simpler and more sustainable. When you have a genuine deadline — a seasonal menu that actually ends, a real event with limited seating, a product that's genuinely selling out — say so plainly. When you don't have urgency, don't manufacture it. Just tell your customers what's happening, why it's worth their time, and how to take advantage of it. This is exactly how Cherub's AI is built to write — honest, specific, helpful. No fake urgency, no manipulation tactics. It's the only strategy that compounds over time instead of depleting itself.

Even a perfectly written email will underperform if it goes to the wrong audience. Over 90% of email marketers report that segmentation improves their campaign performance, and the reason is intuitive: a lapsed customer who hasn't visited in three months needs a different message than a loyal regular who was in last week.

You don't need complicated automation to segment effectively. The simplest and most impactful segments for a small business come down to three dimensions. First, recency: separate your first-time visitors from your repeat customers from your lapsed ones. A first-time visitor might need a welcome offer to come back. A loyal regular just wants to know what's new. A lapsed customer might need a "we miss you" nudge with a genuine reason to return.

Second, engagement level. Some subscribers open every email you send. Others haven't opened one in months. Sending the same email to both groups hurts your deliverability because email providers notice when a large percentage of recipients ignore your messages. Your highly engaged subscribers are your best audience for new offers and announcements. Your disengaged subscribers need a re-engagement campaign — or to be removed from your list entirely.

Third, preferences and behavior. If you're a salon, the customer who always books color services doesn't need to hear about your men's barbering specials. If you're a restaurant, the couple who comes in every Friday for date night is a different audience than the family that does Sunday brunch. Even basic preference data — what they've purchased, when they typically visit, what they've clicked on in past emails — lets you write messages that feel personal rather than generic. If this sounds like a lot of work, it doesn't have to be. Cherub pulls product and purchase context from your POS and adapts campaign content automatically. The AI knows whether to highlight your new seasonal blend or your color services based on what your business actually offers.
