Mastering Email Marketing: Tactics to Boost Deliverability and Engagement

Email marketing is a billion-dollar industry, but running successful email campaigns is getting more challenging. With data decaying faster than ever and email service providers enforcing stricter sending rules, your business may already be experiencing declining results. Here’s how you can quickly adapt to these critical industry updates.

Email marketing has come a long way since that historic day in May 1978, when Gary Thuerk sent the first email campaign. Although unsolicited, that mass email generated $12 million in sales. Nearly five decades later, email is still a revenue-generating powerhouse, with studies predicting it will be valued at $17.9 billion by 2027. The promising ROI of email campaigns entices many businesses to build email marketing programs. For many, however, achieving success takes longer than they expect.

1. Adhere to Revised Email Dispatch Guidelines

Navigating the realm of email marketing requires strict adherence to the latest sending guidelines to ensure that your emails reach their recipients’ inboxes rather than getting lost in spam folders. One crucial step in this is email authentication. Google and Yahoo have set a standard requiring that mass-generated emails be authenticated, thereby verifying the sender’s identity. This authentication measure is now also embraced by Microsoft, with implementation planned for the fall of 2024. The technical process involves setting up SPF (Sender Policy Framework), DKIM (DomainKeys Identified Mail), and DMARC (Domain-based Message Authentication, Reporting & Conformance) records, which authenticate your domain and reassure inbox providers that your emails are legitimate and not attempts at spoofing or phishing.

Equally important is implementing a one-click opt-out feature in your emails. Google and Yahoo require a one-click unsubscribe option, allowing recipients to leave your mailing list easily. This feature enhances the user experience and ensures compliance with new rules. Also, make sure to honor unsubscribe requests within two days. Maintaining low spam complaint ratios is another critical aspect. Spam complaints provide email service providers with a metric to separate genuine, trustworthy senders from spammers. Aim to keep these complaints well under 0.3% to maintain a good reputation. The ultimate goal is to build trust with email service providers and your audience, enhancing your email deliverability significantly.

2. Regularly Clean Up Your Email List

To maintain a strong sender reputation, it’s crucial to regularly clean up your email list to declutter invalid or outdated email addresses that could harm your deliverability rates. More than 25% of an average email list decays each year, a trend that has worsened compared to previous years. To counter this, it’s advisable to verify your contacts at least quarterly. Using email verification tools can quickly identify obsolete addresses, allowing you to remove them proficiently from your list.

Verifying your contacts is essential to maintaining a low bounce rate, ideally under 2%. High bounce rates indicate to email service providers that your list is not current, which can flag your account as problematic and compromise your sender reputation. An email checker helps isolate invalid addresses, ensuring your email campaigns reach active and engaged users. Regular list maintenance not only keeps your bounce rate low but also ensures that you’re reaching out to contacts genuinely interested in your offerings, thus improving overall engagement and performance.

3. Avoid Purchasing Contact Lists

Purchasing contact lists might seem like a shortcut to expanding your reach, but this practice can severely harm your email marketing efforts in the long run. Contacts on purchased lists usually didn’t opt-in to receive communications from your brand, making them more likely to mark your emails as spam. Such actions drastically increase your spam complaint rate, tarnishing your sender reputation and harming your email deliverability.

Instead of purchasing lists, focus on organically building your database of consented subscribers. Use opt-in forms on your website, social media channels, and during sales transactions to collect email addresses from individuals who genuinely want to hear from you. Provide valuable content or incentives to encourage sign-ups, such as discounts, exclusive offers, or informative newsletters tailored to their interests. This strategy not only ensures compliance with email marketing laws but also builds a more engaged and responsive audience, leading to better open rates, click-through rates, and conversions.

4. Deliver the Content You Promised

One of the key elements in maintaining a healthy email marketing campaign is delivering the type of content you promised to your subscribers during their sign-up. This builds trust and keeps your audience engaged. If users subscribed to your list expecting newsletters about a specific topic, such as marketing tips, then ensure your emails align with that subject. Likewise, if they signed up for discount offers, provide them with timely and relevant promotions.

Staying true to your initial promise enhances your credibility and encourages higher engagement metrics. When subscribers receive the content they expect, they are more likely to open your emails, click through, and take the desired actions, whether it’s making a purchase or sharing your content. Consistency in the quality and relevance of your email content helps build a loyal audience that looks forward to receiving your messages, ultimately leading to higher retention rates and a stronger return on investment for your email marketing efforts.

5. Reevaluate Your Content Approach

If you find your email performance metrics stagnating despite following best practices, it might be time to reassess your content strategy. Start by personalizing your email campaigns; use data such as past purchase behavior, browsing history, and user preferences to tailor your content. Personalized emails resonate more with recipients, making them feel valued and understood, which significantly increases engagement.

Conducting A/B tests is another effective method to refine your approach. Test different elements of your emails, such as subject lines, images, copy, and call-to-action buttons, to identify what resonates best with your audience. A/B testing allows you to make data-driven decisions and optimize your emails for maximum impact. Focus on one element at a time during these tests to isolate its effect on your metrics, analyze the results, and then implement the best-performing strategies across your campaigns. Continuous testing and optimization help keep your content fresh, engaging, and aligned with your audience’s evolving preferences.

6. Maintain Consistent Sending Patterns

Consistency in your emailing schedule is a cornerstone of effective email marketing. Sending emails at regular intervals helps inbox providers recognize your patterns as legitimate and not as suspicious behavior often associated with spammers. It also sets the expectation for your audience, making them more likely to engage with your content. Avoid long hiatuses between sends, as irregular sending can cause your audience to forget about you, increasing the chances they will mark your subsequent emails as spam.

Sudden increases in email volume can also trigger red flags with email service providers. For example, if you typically send weekly emails and suddenly ramp up to daily emails, it can appear as erratic behavior, affecting your deliverability. Find a sending frequency that works for your audience and stick to it. This steady approach builds trust with both email service providers and your subscribers, fostering a reliable communication channel that enhances the overall performance of your email campaigns.

7. Adjust Sending Intervals to Match Audience Needs

Monitoring your unsubscribe rates is crucial to understanding whether your email frequency aligns with your audience’s preferences. The primary reason people unsubscribe from mailing lists is because they are inundated with too many emails. If you notice a high rate of unsubscribes, it’s a clear signal to reduce your email frequency. Sending fewer but more valuable emails can help retain subscribers and improve engagement.

Finding the right balance in your sending schedule requires close monitoring of your engagement metrics. Use data to determine the optimal frequency that keeps your brand top of mind without causing email fatigue. Regularly analyze open rates, click-through rates, and feedback from subscribers to gauge their comfort level with your email frequency. Adjusting your sending intervals in response to these insights ensures your emails remain a welcome and anticipated part of your subscribers’ inbox rather than an annoyance, enhancing their overall experience with your brand.

8. Summarize Your Email Marketing Strategy

In conclusion, creating a successful email marketing strategy involves ongoing efforts and adherence to best practices that adapt to evolving industry standards. Regularly updating your email list and avoiding the purchase of contact lists help maintain a strong sender reputation. Authenticating emails and providing easy opt-out options ensure compliance and build trust with both email providers and subscribers. Delivering the content you promised and personalizing your emails can significantly improve engagement metrics.

Consistently sending emails at regular intervals, avoiding long breaks or sudden volume increases, and adjusting your sending frequency based on audience feedback are key factors in maintaining a healthy and effective email marketing program. Each of these steps, while they may seem overwhelming at first, ultimately boils down to common sense and ethical marketing principles. A thoughtful, data-driven approach to email marketing not only yields better results but also builds a loyal and engaged subscriber base, paving the way for long-term success.
