Tips to keep your rental reminders from going into junk.

Learn effective strategies to improve rental reminder email deliverability and keep your communications out of spam folders.

Rental reminder emails often end up in spam folders due to overly cautious filters used by major email providers like Gmail and Outlook. This creates missed communications, frustrated customers, and extra work for your team. The good news? You can fix it by improving your email practices and technical setup.

Key Steps to Improve Email Deliverability:

  • Set Up Email Authentication: Use SPF, DKIM, and DMARC protocols to verify your emails and reduce spam flags.
  • Use Professional Sender Details: Stick to a consistent sender name and domain-based email address (e.g., reminders@yourbusiness.com).
  • Write Clear Subject Lines: Avoid spammy phrases like “urgent payment required” and keep subject lines straightforward.
  • Maintain a Clean Email List: Only email users who’ve opted in and remove inactive addresses regularly.
  • Include Unsubscribe Links and Business Info: Ensure every email has an easy opt-out option and your full business details.
  • Test Emails Across Providers: Check how your emails appear on Gmail, Outlook, and other platforms to catch issues early.
  • Encourage Safe Sender List Additions: Ask customers to whitelist your email to improve deliverability.

1. Set Up Email Authentication for Your Domain

Technical Setup for Email Deliverability

Getting your rental reminders into recipients' inboxes starts with proper email authentication. Without it, email providers may struggle to confirm that messages are genuinely coming from your domain, increasing the chances of them landing in spam folders.

Here’s how the key protocols work:

  • SPF (Sender Policy Framework): This protocol specifies which IP addresses are authorized to send emails on behalf of your domain.
  • DKIM (Domain Keys Identified Mail): DKIM adds a digital signature to your emails, ensuring the content hasn’t been tampered with. The signature is generated using a private key, while the public key is stored in your DNS records for verification.
  • DMARC (Domain-based Message Authentication, Reporting, and Conformance): This policy tells email providers how to handle messages that fail SPF or DKIM checks.

As explained by experts:

"Technologies recommended in support of core Simple Mail Transfer Protocol (SMTP) and the Domain Name System (DNS) include mechanisms for authenticating a sending domain: Sender Policy Framework (SPF), Domain Keys Identified Mail (DKIM) and Domain-based Message Authentication, Reporting and Conformance (DMARC)."

  • Scott Rose (NIST), Stephen Nightingale (NIST), Simson Garfinkel (U.S. Census Bureau), Ramaswamy Chandramouli (NIST)

To implement these protocols, you’ll need to update your DNS records. This process typically involves adding specific TXT records, which your web host or IT team can handle. Many email service providers also offer step-by-step guides to make setup easier.

Once authentication is in place, email deliverability improves with major providers like Gmail, Outlook, and Yahoo. With this foundation set, you’re ready to fine-tune your sender details in the next step.

2. Use Consistent Sender Names and Professional Email Addresses

Customer Engagement and Trust-Building Strategies

When it comes to email communication, consistent sender details play a huge role in building trust and credibility. Your sender name and email address are the first things recipients notice. Keeping these consistent not only fosters recognition but also helps reduce the chances of your emails being flagged as spam. Let’s explore how maintaining a professional approach to sender details complements email authentication efforts.

Fraudulent emails are everywhere, making it essential to use professional and consistent sender information. This practice works hand-in-hand with technical authentication measures, giving customers clear and reliable points of verification.

For example, always stick to a single sender name. If your business is "Downtown Apartments", don’t switch between variations like "Downtown Apts", "DT Apartments", or individual staff names. Consistency ensures email providers recognize your messages as legitimate and helps customers instantly associate the email with your business.

Additionally, use a business domain for your email address. Instead of something generic like downtownapartments123@gmail.com, opt for a domain-based address such as reminders@downtownapartments.com. This not only looks more professional but also reinforces your business’s identity.

Avoid using abbreviations, numbers, or special characters in your email addresses, as these can trigger spam filters or seem unprofessional. Your sender details should align perfectly with your business identity to make verification easier for both email providers and customers.

To enhance clarity, consider using a sender name like "Downtown Apartments – Rental Reminders." This provides immediate context about the email’s purpose, reducing the likelihood of it being marked as spam. Transparency is key - customers should feel confident that your messages are legitimate and come directly from their property manager or landlord.

Finally, steer clear of anonymous or vague sender details. These can create doubt and make it harder for customers to trust your emails. By clearly identifying your business in every communication, you ensure customers feel secure and informed when receiving your rental reminders.

3. Write Clear Subject Lines and Avoid Spam Triggers

Subject lines play a crucial role in the success of your emails. They should be clear, concise, and directly tied to the email's content. According to best practices, avoiding exaggerations or misleading phrasing ensures your audience immediately understands the purpose of the message. Plus, it can improve your email's chances of landing in the inbox rather than the spam folder.

Another important tip: maintain a clean, permission-based email list. This not only supports better deliverability but also helps ensure your emails reach the right audience.

4. Keep Your Email List Clean and Permission-Based

Maintaining a clean, permission-based email list is crucial to ensure your rental reminders reliably reach your customers. If your list includes contacts who haven’t explicitly agreed to receive emails, it can signal to email providers that your messages might be spam. This can harm your sender reputation and increase the chances of your emails landing in junk folders.

A permission-based list means every recipient has actively opted in - whether through a checkbox during booking, account creation, or update requests. Regularly maintaining this list is just as important. Remove email addresses that consistently bounce, unsubscribe users who haven’t engaged with your emails in six months, and segment your audience based on how they interact with your messages. Active customers who open and engage with your emails improve your sender reputation. And one golden rule: never buy email lists.

Staying compliant with legal standards is another step to keep your emails effective and trustworthy.

Compliance with US Anti-Spam Laws (e.g., CAN-SPAM Act)

A well-maintained email list not only meets legal requirements but also builds trust with your customers. The CAN-SPAM Act requires every email to include your physical address, a simple way to unsubscribe, and prompt processing of opt-out requests. Your subject lines also need to be clear and honest - no misleading claims or fake urgency.

Failing to comply can lead to financial penalties and serious damage to your reputation. Keep records of customer opt-ins to show you’re following the rules and to reinforce trust with your audience.

Beyond legal and technical considerations, keeping your subscribers engaged is key to strong email performance.

Customer Engagement and Trust-Building Strategies

Engaged subscribers are your best allies in avoiding spam filters. When customers consistently open, read, and interact with your rental reminders, email providers see your messages as valuable, increasing their chances of landing in inboxes.

Send timely, relevant content, like pickup confirmations or return deadlines, to keep subscribers engaged and reduce unsubscriptions. Be mindful not to send promotional emails to users who only signed up for transactional updates.

Segmentation is a powerful way to improve engagement. Divide your list based on factors like how often customers rent, the type of equipment they use, or their specific preferences. For example, a contractor who rents heavy equipment monthly will likely appreciate different emails than someone renting party supplies for a one-time event. Tailored messaging keeps your audience interested and reduces the risk of unsubscribes.

Finally, pay close attention to your email metrics. If your open rates dip below 15% or click rates fall under 2%, it’s a sign your list might need attention. A high unsubscribe rate could mean you’re emailing too frequently or your content isn’t resonating. Use these insights to refine your strategy and address potential issues before they affect your deliverability.

After setting up proper authentication and consistent sender practices, the next step is to ensure your emails include clear unsubscribe links and complete business details. These elements are essential for keeping your messages out of spam folders. Every rental reminder email should feature an easy-to-find unsubscribe link and full business information to avoid being flagged as spam.

Place the unsubscribe link prominently in the footer with straightforward text like "unsubscribe here." The process should be quick and simple, allowing customers to opt out with just one or two clicks.

Additionally, include your business's physical address in every email. This not only verifies your legitimacy but also helps build trust with recipients and email providers. Including your full business name, mailing address, and contact information reinforces your credibility and supports your overall email deliverability efforts.

Compliance with US Anti-Spam Laws (e.g., CAN-SPAM Act)

Adhering to legal requirements, such as those outlined in the CAN-SPAM Act, goes beyond compliance - it also strengthens customer trust. The law mandates that every email must include a clear unsubscribe option that works immediately. Once a customer opts out, you have up to 10 business days to process their request. Ignoring these rules could lead to hefty penalties. By promptly handling unsubscribe requests, you not only stay within legal boundaries but also show respect for your customers' preferences.

Customer Engagement and Trust-Building Strategies

A well-thought-out unsubscribe process can actually enhance trust and improve customer engagement. When subscribers see that you value their preferences and make it easy for them to manage their email settings, they’re more likely to remain engaged. Offering a preference center is a smart way to achieve this. For instance, you could let customers choose the type of emails they want to receive - like pickup reminders instead of promotional offers - or adjust the frequency of communications. Giving subscribers this level of control can reduce complete opt-outs and keep your audience more engaged.

You can also use the unsubscribe confirmation page as an opportunity to thank customers for their time and offer re-subscription options. Some rental businesses take it a step further by suggesting alternative communication methods, like text message reminders, for those who prefer a different channel.

Lastly, keep a close eye on your unsubscribe rates. A sudden increase could signal issues with your email content, frequency, or targeting. Addressing these problems quickly is critical for maintaining a positive sender reputation and fostering strong relationships with your customers.

6. Track Email Performance and Avoid Blacklists

Keeping an eye on your email performance is essential if you want your rental reminders to land in inboxes instead of junk folders. Without proper tracking, you might not even realize your emails are being blocked or ignored. Regularly monitoring your email performance helps you catch problems early and take action before they escalate. Start by focusing on key metrics that highlight potential risks.

Pay attention to delivery rates, open rates, and bounce rates. If you notice sudden changes - like a spike in bounce rates - it’s a red flag that something’s wrong. High bounce rates, in particular, can hurt your sender reputation, so you’ll want to dig into the causes right away.

Don’t forget to routinely check if your domain or IP address has landed on any major blacklists. Tools like MXToolbox and Barracuda Central make this process straightforward. If you find your domain on a blacklist, act fast to get it removed and protect your reputation. Also, keep an eye on spam complaints - any sudden increase should be addressed immediately to ensure your emails continue to reach your audience.

On the technical side, make sure your SPF, DKIM, and DMARC settings are correctly configured (refer back to Section 1 for more details).

Customer Engagement and Trust-Building Strategies

Beyond technical fixes, engaging your customers is a powerful way to strengthen your email reputation. When customers find your emails useful and timely, they’re more likely to interact with them - and that interaction signals to email providers that your messages are worth delivering. For instance, send reminders about upcoming equipment returns or pickups, as these are messages your customers are likely to value.

Another effective strategy is encouraging customers to whitelist your email address. Provide simple, step-by-step instructions for popular email clients to make this process easy. Finally, keep an eye on engagement trends and adjust your email frequency based on how your customers respond. Balancing relevance and timing can go a long way in maintaining a strong sender reputation.

7. Test Your Emails Across Different Email Providers

Email platforms like Gmail, Outlook, Yahoo Mail, and Apple Mail each handle messages differently. Testing your rental reminders across these platforms ensures they display properly and don’t end up in spam folders. Set up test accounts with the most popular email services your customers use. Send your rental reminder templates to these accounts to spot formatting issues, missing images, or text that doesn’t render correctly. Don’t forget to test how your emails look on mobile devices as well.

Gmail is generally lenient with deliverability but may block images by default. Outlook has stricter spam filters and often removes certain HTML elements, making it more challenging. Yahoo Mail falls somewhere in between but can behave unpredictably with newer domains. Apple Mail, while good at displaying emails, has strong privacy features that might impact your tracking.

Technical Setup for Email Deliverability

Ensuring your authentication records are correctly configured is crucial, as each email provider evaluates them differently. For example, Gmail prioritizes DMARC alignment and may quarantine emails that fail these checks. Outlook, including Exchange Online, is particularly strict with SPF records and will reject emails with improper configurations.

To verify your setup, send test emails from your rental reminder system to accounts across various platforms. Use tools like Mail Tester or GlockApps to confirm that your SPF records show a 'PASS,' DKIM signatures are intact, and DMARC policies align correctly across all providers.

Once authentication is confirmed, shift your focus to the content and design of your emails to ensure they don’t trigger spam filters.

Content and Design Tips to Avoid Spam Filters

Your email’s subject lines and HTML formatting play a big role in deliverability. Avoid using phrases like "urgent payment required" or "final notice", as these are often flagged as spam. Instead, opt for clear and straightforward subjects such as "Equipment return due tomorrow" or "Rental pickup scheduled for [date]."

HTML design can also be a sticking point. Some providers strip out CSS styles or block images by default. Test your emails with images turned off to make sure the message still makes sense. Keep your HTML simple - avoid overusing colors, fonts, or excessive formatting that might raise red flags.

Stick to essential links, such as those leading to your customer portal or contact information, and ensure all URLs point to a verified domain. Limiting the number of links in your email can also help avoid spam triggers.

Finally, monitor your sender reputation by tracking delivery rates across different platforms. If you notice consistent issues with one provider - like Outlook rejecting emails while Gmail delivers them - you can adjust your strategy to meet that provider’s specific standards.

8. Help Customers Add Your Email to Their Safe Sender List

After tackling authentication and maintaining a clean email list, the next step is ensuring your messages consistently land in your customers' inboxes. One effective way to do this? Encourage tenants to add your email address to their safe sender list. When customers take this step, it sends a strong signal to email providers that your messages are both trusted and valued.

How to Build Trust and Encourage Engagement

Introduce this idea during the onboarding process. Let tenants know that adding your email to their safe sender list guarantees they won’t miss important updates - like payment reminders or booking confirmations. To make it easy, include a simple, step-by-step guide in your welcome or confirmation emails. Keep the instructions straightforward so customers can follow along without feeling overwhelmed.

Clear communication is key here. Your emails should be easy to recognize and free of unnecessary clutter, ensuring they don’t get mistaken for spam.

Design Emails That Avoid Spam Filters

The design and content of your emails play a big role in deliverability. A polished, professional look not only builds trust but also reduces the chances of your messages being flagged as spam. Here’s how to keep things on track:

  • Write in clear, concise language with proper grammar.
  • Prioritize text over heavy image use to maintain clarity and avoid triggering spam filters.

Email Authentication Methods Comparison

Choosing the right email authentication method is a key step in ensuring smooth communication for your rental business. Below, we break down the main methods - SPF, DKIM, and DMARC - with a handy comparison table and explanations to help you determine what fits your business needs.

SPF (Sender Policy Framework) verifies whether the sending server is authorized by checking approved IP addresses. It’s a simple approach but only confirms the legitimacy of the sender’s server, leaving other vulnerabilities unaddressed.

DKIM (DomainKeys Identified Mail) uses a digital signature to validate the sender's identity and ensure the message hasn’t been tampered with. This method offers stronger security than SPF by protecting both identity and message integrity.

DMARC (Domain-based Message Authentication, Reporting, and Conformance) builds on SPF and DKIM. It enforces policies and provides detailed reports, making it a comprehensive solution. As Amaya Woods from Chaser HQ highlights:

"Verifying your identity through SPF, DKIM, and DMARC is the first line of defense against spam filters".

Authentication Method Setup Difficulty Protection Level Best Use Case for Rental Businesses
SPF Moderate Basic Small operations with simple email needs
DKIM Moderate to High Strong Businesses sending moderate email volumes
DMARC High Comprehensive High-volume rental operations requiring maximum deliverability

For rental businesses that rely on email for contactless solutions - like payment reminders or booking confirmations - DMARC stands out as the most dependable option. Its advanced features help ensure that vital messages aren’t mistakenly flagged as spam, keeping your communication effective and uninterrupted.

Working with your IT team or email provider to implement these methods is crucial. A strong email authentication setup not only improves deliverability but also builds trust with customers, keeping your rental operations running smoothly.

Conclusion

Making sure rental reminders land in your customers' inboxes requires a mix of technical precision and good email practices. Setting up email authentication protocols like SPF, DKIM, and DMARC is a key step in building trust with email providers.

A strong sender reputation also plays a major role. This means using consistent email addresses, crafting clear subject lines, maintaining permission-based email lists, and complying with unsubscribe regulations. Testing emails across various providers can help catch potential issues early, ensuring smooth delivery.

When payment reminders, booking confirmations, and updates reliably reach your customers, it strengthens communication and keeps your operations running smoothly. Reliable email delivery isn’t just about logistics - it’s about building trust and maintaining strong customer relationships.

To get started, focus on authentication first. From there, refine your list management, improve email content, and thoroughly test your setup. By tackling these steps one at a time, you’ll create an email system that supports seamless communication and long-term success in your rental business.
