Best Practices for SMS and Email Templates in Rentals

Clear communication is the backbone of a successful rental business. Whether you're managing automated trailer rentals or bike bookings, crafting effective SMS and email templates can save time, reduce confusion, and improve customer satisfaction. Here's what you need to know:

• SMS messages have a 98% open rate, compared to 28% for emails. Use SMS for urgent updates and emails for detailed instructions.
• Automating pre-arrival emails can cut customer inquiries by 50%, while post-stay review requests can boost response rates to 25–40%.
• Keep messages short and to the point. Use clear formats like: [Brand]: [Event] [Details] [Call-to-action].
• Personalize communications with customer names, booking details, and specific instructions.
• Maintain a friendly yet professional tone that reflects your brand identity. This is especially important when moving away from trailer rental marketplaces to build your own independent brand.
• Ensure templates are mobile-friendly and include clear calls to action (e.g., "Reply YES to confirm").
• Leverage automation to insert dynamic fields like names, dates, and access codes, reducing manual errors.
• Test thoroughly for errors and compliance with regulations like the TCPA.

Bottom Line: Streamlined, automated, and well-timed messaging not only enhances the customer experience but also frees up your team for critical tasks. Tools like Lockii can simplify this process, ensuring every rental interaction is smooth and professional.

1. Keep Messages Clear and Concise

Straightforward and concise messages are key to effective rental communication. They make personalization easier and help reinforce your brand. Most people check messages on their phones during busy moments, so they don’t have time to dig through lengthy texts for what they need. Plus, SMS messages have a 160-character limit, meaning every word needs to count[8].

Start with your brand identity and focus on the most critical information. For transactional SMS, stick to this format: [Brand]: [Event] [Details] [Call-to-action]. Here’s an example: "Acme Rentals: Your trailer pickup is confirmed for June 1, 2026, at 9:00 AM. Access code: 4582. Questions? Reply here." This approach ensures all the key details are delivered upfront.

"The goal when writing any rent-related message is to ensure your purpose is clear from the jump." - Textline[7]

To avoid SMS limits caused by Unicode characters, use straight quotes, three periods for ellipses, and double hyphens instead of em dashes[8]. Skip emojis in transactional messages to save space. When including dates, spell out the month (e.g., "May 3, 2026") to eliminate confusion from numeric formats. These same principles apply to messaging templates for rental businesses, helping maintain clarity and brevity.

With 60% of emails being read on mobile devices[5], it’s essential to use short paragraphs, limit bullet points, and stick to single-column layouts. This ensures critical instructions won’t get clipped in Gmail or other email platforms.

2. Personalize with Customer and Booking Details

Nobody enjoys receiving a generic message - it feels impersonal and often gets ignored. By including details like the customer's name, booking number, and rental dates, you turn mass notifications into messages that feel tailored and relevant. Here's a fun fact: SMS messages with personalized details boast a 98% open rate, and about 90% are read within three minutes of being sent[10][11].

The secret here is using auto-populated fields. Instead of sending something vague like, "Your rental is ready", try this: _"Sarah, your 6x12 trailer (#B4582) is ready for pickup on June 15, 2026, at 10:00 AM. Access code: 7293."_ This method not only saves time but also makes every message feel like it was written just for that customer[9].

To make your messages instantly relevant, focus on key details like:

• The customer's name
• A clear description of the item (not just "your rental")
• Confirmation or booking numbers
• Specific pickup or return times

For maintenance alerts, include a brief description of the issue and the affected equipment. For payment confirmations, mention the exact dollar amount. These small touches provide reassurance and cut down on follow-up questions[9].

Be mindful of SMS character limits. For instance, "Jennifer Richardson" takes up 22 characters - about 14% of a 160-character SMS. In cases where space is tight, using just the first name or skipping the greeting altogether may be better to prioritize the booking details[8]. Always aim for relevance over formality to ensure your messages hit the mark.

3. Use Friendly and Professional Tone

Texting naturally leans toward a casual style, which makes it easier to adopt a friendlier tone while still keeping it professional. As Textline explains:

"Texting is a more casual channel than email so you can relax the tone a bit when communicating via SMS. Plus, a friendly tone can go a long way in building relationships with tenants." [7]

The key is to find the sweet spot where your messages feel approachable and helpful, without losing the professionalism that builds trust and credibility.

Your brand identity should guide the tone of your texts. Meagan Shelley, a Professional Writer at Quo, emphasizes this point:

"Your brand voice should be the sculptor of your business texts and emails. A luxury property wouldn't communicate the same way a college-town studio apartment would." [6]

For instance, a luxury car rental might say, "We're pleased to confirm your reservation", while a surf rental shop might go with, "Excited to have you on board!" Both convey professionalism but are tailored to their specific audiences. These tone adjustments not only enhance clarity but also make your messages feel more personal and relevant.

When sending rent reminders or payment notifications, keep the language approachable. Instead of saying, "Payment is required by the due date", try, "Just a quick heads-up that your payment is due on June 1, 2026." For first-time late payments, a message like, "We noticed a missed payment yesterday. Please settle your $150.00 balance to avoid a late fee", strikes a balance between being polite and direct.

Even maintenance and support messages can benefit from a warm touch. Rather than saying, "A technician will arrive", you could write, "We want to get this sorted ASAP for you! Our maintenance team will swing by on May 8, 2026, at 2:00 PM." Closing with phrases like "We're here to find a solution together" or "Thank you for your prompt attention to this matter" reinforces both helpfulness and professionalism.

To maintain consistency, always start your SMS with your brand name. For example, a message like "Coastal Rentals: Your bike is ready for pickup at 123 Main St. Access code: 4829" immediately provides context and builds trust [8].

4. Incorporate Strong Branding Elements

After establishing clear, personalized, and friendly communication, consistent branding takes your rental business to the next level. Your brand isn’t just a logo - it’s the impression you leave on your customers. As Buildium puts it, "Your brand should be consistent across everything you create for your business, in the same way big brands create a consistent look and feel throughout all of their properties and channels" [4]. This type of consistency makes your messages instantly recognizable and helps build trust over time. Let’s dive into how branding elements can differ between email and SMS.

When it comes to email templates, visual branding plays a key role. Start with your company logo prominently displayed in the header. Use your brand’s color palette for call-to-action buttons and borders, and stick to the same fonts you use on your website. To ensure consistency, create an email style guide that outlines how to apply your logo, colors, and fonts. Don’t forget to optimize for Dark Mode, as many users now prefer this setting [13].

For SMS, branding requires a simpler but equally impactful approach. Always lead with your brand name to establish immediate recognition. For example: _"Coastal Rentals: Your surfboard is ready for pickup" or automating trailer rentals with smart locks_ or _"Peak Equipment: Reminder - your rental ends tomorrow at 5:00 PM."_

When including links in SMS messages, avoid generic shorteners like bit.ly. Instead, invest in a branded short domain (e.g., yourbusiness.co/offer). While setting up a branded domain costs between $100 and $500, it’s worth it for the added trust and engagement it brings [8].

Just like tone and clarity, your brand voice should shine through in every message. Rob Hand, Lead Product Marketing Manager at Klaviyo, highlights this perfectly: "The brands that do SMS marketing well are able to infuse their personality into it" [12]. Make sure your messages reflect your brand’s personality - whether that’s friendly, professional, or playful - while staying helpful and professional.

5. Optimize for Mobile Devices

When crafting automated notifications for rentals, making sure they work seamlessly on mobile devices is a must. With 98% of text messages opened, and most read within three minutes of receipt [7], it’s clear your audience is checking their phones constantly - whether grabbing coffee, walking to their car, or waiting in line. That means your messages need to look sharp and be easy to digest on smaller screens.

For SMS, the 160-character limit is actually a helpful tool. As Knock puts it:

"The 160-character limit is a forcing function for clarity. Every word must earn its place, and the message must be instantly comprehensible to someone glancing at their phone while walking, driving (at a red light), or in a meeting" [8].

Emails, on the other hand, require a slightly different strategy. Keep paragraphs short, and use large, tappable call-to-action buttons to make navigation easy. Always test your emails on a variety of devices to ensure they display consistently across platforms.

If you’re including links, opt for branded short domains (like _yourcompany.co/track_) instead of generic ones. This not only looks professional but also builds trust with customers who are cautious about security. Plus, it can boost click-through rates [8]. Make sure links are placed after clear context so they’re easy to understand.

Another important detail? Use clear date formats like "May 3, 2026" instead of something ambiguous like "05/03/26." Small adjustments like this prevent confusion. For more ways to streamline your workflow, follow a rental business automation checklist. And with 71% of customers preferring texting as their communication method [7], it’s clear that mobile-first thinking isn’t just nice to have - it’s essential.

6. Include Clear Calls to Action

Every rental notification needs a specific and straightforward call-to-action (CTA). Whether it's "Access your pickup instructions", "Confirm your booking", or "Reply YES to confirm", giving customers a clear next step eliminates confusion and cuts down on support requests.

For emails, bold, tappable buttons are the way to go - especially since over 60% of emails are opened on mobile devices [5]. Instead of hiding links within text, use high-contrast buttons like "View Welcome Guide" or "Pay Balance" that grab attention and work well on smaller screens. For SMS, simplicity is key: something like "Click for door code: [Link]" gets the job done without overwhelming the recipient. These targeted actions create a smoother rental process for everyone.

Timing also plays a big role in effective CTAs. For instance, sending check-in instructions 1–3 days before arrival ensures customers have the details they need without last-minute stress. According to Sequenzy, using an automated pre-arrival sequence with clear instructions can reduce guest inquiries by 50% [3]. That means fewer calls, fewer emails, and a much smoother experience overall.

CTAs also shine when it comes to feedback. Automated post-stay review requests with one-click links have been shown to boost review rates from 5–10% to as high as 25–40% [3]. The easier it is for customers to respond, the more likely they are to engage.

Lastly, tailor your CTAs to the specific situation. A booking confirmation email should encourage customers to review their reservation and offer a direct contact option. A maintenance request should ask for issue details and confirm whether entry is allowed. A rent reminder? Include a direct link to the payment portal. When customers know exactly what to do, confusion drops - and so do unnecessary support tickets.

7. Leverage Automation Variables

Automation variables - also known as smart fields or template tokens - are placeholders like {{customerFirstName}} or {{CODE}} that automatically pull in live data for each message. These variables can insert details such as customer names, check-in times, or access codes into your communications. This means one template can be used for hundreds of customers while still maintaining a personal and accurate touch. It’s one of many ways to automate rental business operations to save time on SMS and email communications.

Beyond saving time, automation variables help eliminate human error. For example, when your system inserts the correct PIN code ({{CODE}}), lock name ({{LOCK}}), and check-in date ({{CHECKIN_DATE}}), you avoid the risk of sending incorrect details. This level of precision is especially crucial for rental businesses juggling multiple locations or high booking volumes - a single typo could leave a customer locked out of their rental and frustrated.

These variables are versatile, working seamlessly across SMS and email platforms. They can handle a wide range of tasks, from simple personalization to more complex logistics. Common examples include {{LOCATION}} for pickup addresses, {{CHECKOUT_TIME}} for return deadlines, and {{PULSE_URL}} for digital key links. For advanced needs, you can even use options like {{CHECKOUT|-15}}, which adjusts displayed times to include buffer periods without changing the original booking record [14].

You can also use variables in subject lines to make emails easier to scan and search. For instance, a subject line like "Your rental starts {{CHECKIN_DATE}}" gives customers an immediate understanding of the email's purpose. When using variables in SMS, always test with the longest possible expansions to ensure messages don’t exceed character limits [15]. This small step ensures your automated notifications remain reliable.

In rental operations, automation variables are a game-changer. They ensure the right information reaches the right person at the right time, all while reducing manual effort after the initial setup.

8. Proofread for Errors and Test Thoroughly

Getting your messages right - down to the last detail - is essential for maintaining a professional image and earning customer trust. Even the best templates can fall flat if they contain errors or formatting issues. That’s why it’s crucial to carefully proofread and test every SMS or email before hitting send. This extra step can catch mistakes that might confuse your audience, harm your brand's reputation, or drive up messaging costs.

When focusing on clarity and personalization, thorough testing becomes your safety net. For example, watch out for encoding issues caused by elements like smart quotes, em dashes, emojis, or accented characters. These can trigger Unicode encoding, cutting your character limit per segment from 160 to 70 characters. To avoid this, swap curly quotes for straight quotes and replace em dashes with double hyphens (--). This simple adjustment can save you from unnecessary expenses. You can also use a contactless rental efficiency analyzer to see how these optimizations impact your bottom line.

It’s also smart to test your templates with edge cases. Use the longest customer names and check for missing variables to ensure your formatting holds up under all conditions. Make sure date formats are consistent and easy to understand. Verify that all links are clickable and use branded short domains rather than generic shorteners, which can look suspicious and may even trigger spam filters. For SMS messages, include your brand name at the start of the message since sender names don’t always display on mobile devices.

Finally, send test messages to multiple devices - both iPhone and Android - to see how your templates appear on different screens. Tools like SMS preview generators can help you check line breaks, spacing, and overall readability. By taking these steps, you ensure that your communications meet the high standards your customers expect. This attention to detail not only avoids potential mishaps but also strengthens the trust customers place in your rental business.

9. Time Messages Appropriately

Sending notifications at the wrong time can frustrate customers and cause them to overlook important details. Timing matters.

For example, booking confirmations should go out _immediately_ after a reservation is made. This reassures customers that their booking is secure.

For pickups, consider a staggered approach:

• Send a reminder three days before the scheduled date.
• Provide detailed logistics like access codes, parking info, or instructions one day prior.
• On the day of arrival, follow up with a friendly welcome message [3].

When it comes to returns, a notification one day in advance works best. Include a checklist for securing rentals (like refueling, cleaning, or inspection reminders) to help customers avoid delays or unexpected issues.

Review requests should be timed carefully. Aim for 1–3 days after the rental, while the experience is still fresh. As Sequenzy explains:

"Ask too soon and guests have not processed the experience. Ask too late and they have moved on" [3].

Using automated post-stay review sequences can significantly improve review rates, increasing them from 5–10% to as much as 25–40% [3]. This efficiency is a key benefit of scaling with contactless rental models.

Finally, the communication channel you choose can make or break your message's effectiveness. For urgent updates, like door codes or pickup confirmations, SMS is ideal - 98% of texts are opened quickly [7]. For more detailed information, such as instructions or documentation, email is the better choice.

10. Comply with Regulations and Permissions

Failing to follow SMS and email regulations can hit your rental business hard, with fines reaching thousands of dollars. The Telephone Consumer Protection Act (TCPA) mandates obtaining "prior express written consent" before sending promotional texts. Ignoring this can lead to penalties of up to $1,500 per unauthorized message [16].

When gathering phone numbers through web forms, steer clear of pre-selected consent boxes. Instead, provide clear links to SMS terms, conditions, and privacy policies [17]. For added security, adopt a double opt-in process, where customers confirm their subscription through a follow-up text. As Quo notes:

"If the way you collect consent can't be verified, your registration may be rejected" [18].

State-specific laws also come into play, adding more rules to navigate. For example, Florida restricts businesses to sending no more than three commercial messages within a 24-hour period and bans texts before 8 a.m. or after 8 p.m. EST [16]. In Texas, starting September 1, 2025, businesses must register with the state and pay a $200 fee [16]. Meanwhile, California's CCPA gives consumers the right to request details about how their data is used and requires businesses to process opt-out requests within 15 days [16].

Every SMS marketing message must include clear unsubscribe instructions, using standard keywords like "STOP" to opt out and "HELP" for assistance. These are universally recognized by both carriers and customers [16]. For email campaigns, the CAN-SPAM Act requires honoring opt-out requests within 10 business days and including your physical postal address in every email [19].

Keep thorough records of customer consent, such as screenshots or call recordings, to protect your business [16]. Avoid sharing sensitive information via SMS; instead, rely on secure email or customer portals [2]. Federal rules also prohibit sending messages before 8 a.m. or after 9 p.m. in the recipient's local time zone [16].
