How To Optimize Email Deliverability For Your Business

Ever hit “send” on an amazing email campaign, only to wonder if it actually reached your subscribers’ inboxes? 

That’s where email deliverability comes in…

Email deliverability is the magic of getting your emails to land where they belong, not disappearing into the spam folder. 

But it’s not always so simple. There are many factors that can affect email deliverability, from your subject line to the content of your emails.

So, what steps should you take to ensure your emails get delivered, opened, and clicked on? 

In this blog, we’ll delve into the world of email deliverability. From best practices to avoid spam filters to optimizing your content for the inbox, we’ve got you covered.

Why Email Deliverability Matters 

So, you’ve poured your heart and soul into crafting an email campaign – catchy subject line, engaging content, and a call to action that compels. 

But if your emails aren’t reaching their destination, all that effort goes to waste. 

Here’s why email deliverability is crucial for your business:

The Cost of Low Deliverability

Lost Revenue: Email marketing boasts a stellar return on investment (ROI). For every $1 spent, you can expect an average return of around $36. Now, let’s factor in open rates, which typically hover between 30-40%. One major culprit behind low open rates? You guessed it – email deliverability. Emails landing in spam folders or promotional tabs are easily overlooked, significantly decreasing the chances of engagement. Maximizing open rates and ensuring every email reaches the inbox is key for a high ROI. 

Wasted Resources: Low deliverability isn’t just about missed opportunities; it’s about wasted resources. Every bounced or undelivered email represents time and effort spent on content creation, design, and list management that ultimately goes unseen.

Loss of Trust With Email Providers: A string of emails landing in spam can trigger a red flag for email providers. They might start filtering your future emails even more aggressively, creating a vicious cycle that’s tough to break.

Building Trust and Brand Reputation

On the flip side, good email deliverability fosters a healthy relationship with your subscribers. When your emails consistently reach their inboxes, you build trust and strengthen your brand reputation. 

People appreciate it when you respect their time and inbox space. This positive experience translates into higher open rates, increased engagement, and ultimately, a more loyal customer base. 

Factors Affecting Email Deliverability

Now that you understand the importance of email deliverability, let’s delve into the key factors that influence it.

Sender Reputation 

Your sender reputation is essentially your email-sending history report card. Email providers use various tools to assess your reputation, including:

  • SPF (Sender Policy Framework): This authentication protocol verifies that your emails are coming from authorized sources.
  • DKIM (DomainKeys Identified Mail): DKIM digitally signs your emails, ensuring they haven’t been tampered with during transit.
  • DMARC (Domain-based Message Authentication, Reporting & Conformance): DMARC takes things a step further by giving you insights into how effectively SPF and DKIM are working for your emails and helps identify potential misuse of your domain.

If you don’t have these protocols set up correctly, your emails could end up in the spam folder or not get delivered at all.

Email List Hygiene 

Your email list is your most valuable asset in email marketing. 

By maintaining a clean and healthy list, you ensure your emails reach people who are genuinely interested in your content. This can improve overall engagement and deliverability rates.

Email Content

The content of your emails plays a significant role in reaching inboxes and engaging subscribers. 

Focus on crafting compelling, informative emails that provide value to your subscribers. This not only keeps them engaged but also tells email providers your emails are relevant and desired.

Sending Frequency and Timing

How often and when you send emails can also influence deliverability. 

Bombarding subscribers with constant emails can overwhelm them and trigger spam filters. Find a sending frequency that strikes a balance between staying relevant and respecting subscriber preferences.

By implementing a strategic sending schedule, you ensure your emails reach subscribers when they’re most receptive, ultimately boosting engagement.

Email Design and Mobile Friendliness 

In today’s mobile-first world, how your emails look and function on different devices matters. 

By prioritizing a clean, responsive email design, you guarantee a positive user experience across all devices. This can increase engagement and maintain a good sender reputation.

Strategies to Improve Email Deliverability

Now that we’ve identified the key factors affecting email deliverability, let’s explore actionable strategies to optimize each one and ensure your emails land where they belong: inboxes, not spam folders.

Authentication Techniques

Remember the importance of sender reputation? Setting up these authentication protocols is a must-do:

SPF (Sender Policy Framework): Work with your domain provider to configure an SPF record that specifies authorized email servers for your domain. There are several online tools and guides to help you set up SPF.

DKIM (DomainKeys Identified Mail): Set up DKIM to digitally sign your emails. Most email marketing platforms offer built-in DKIM functionalities, or your domain provider might offer instructions.

DMARC (Domain-based Message Authentication, Reporting & Conformance): Implement DMARC to receive reports on how well your emails are authenticated and what happens to those that fail. DMARC is a bit more technical, but many email marketing platforms offer integration or can provide guidance.

Building a Clean Email List

A healthy email list is the foundation of successful email marketing. Here’s how to ensure yours is top-notch:

Permission-Based Opt-Ins: Always use confirmed opt-in methods, like double opt-in, where subscribers need to verify their email address after signing up. This ensures you have valid addresses and consent from those who want to receive your emails.

List Hygiene Practices: In order to keep your list clean, you must regularly remove inactive subscribers. Many email marketing platforms offer tools to identify inactive subscribers based on open rates or click-through rates. You can also set up automated campaigns to re-engage inactive subscribers or offer them an unsubscribe option.

By maintaining a clean list, you not only improve deliverability but also ensure your emails reach engaged recipients. This can lead to better overall campaign performance.

The content of your emails directly impacts how subscribers interact with them, which in turn affects deliverability. Here are some tips for creating engaging email content that commands attention:

  • Personalization: Use subscriber data to personalize your emails with greetings, product recommendations, or content tailored to their interests. This increases relevance and engagement. Most email marketing platforms offer built-in personalization features.
  • Avoiding Spammy Language: Steer clear of excessive exclamation points, ALL CAPS, misleading subject lines, or overly promotional language. Focus on clear, concise communication that provides value to your subscribers.

By prioritizing valuable, engaging content, you encourage subscribers to open and interact with your emails. This can send positive signals to domain providers and boost email deliverability.

Optimizing Email Design 

The design of your emails can also impact email deliverability. Here’s what to keep in mind:

  • Mobile-Friendly: Ensure your emails render flawlessly on smartphones and tablets. Use responsive design templates or test your emails across different devices with tools offered by many email marketing platforms.
  • Clean Layout: Maintain a clean, uncluttered layout with a healthy balance between text and images. Too many images can trigger spam filters, so prioritize clear messaging and readability.

By creating mobile-friendly emails with a clean design, you ensure a positive user experience across all devices. This can encourage engagement and improve sender reputation.

Measurement and Tracking

So you’ve implemented strategies to optimize email deliverability, but how do you know they’re working? The answer lies in measurement and tracking. 

Monitoring key email deliverability metrics is essential for understanding the health of your email marketing efforts. These metrics act as a compass, guiding you toward continued success.

Here are some crucial deliverability metrics to keep a close eye on:

  • Open Rates: The percentage of subscribers who open your emails. A healthy open rate indicates engaged subscribers and a good sender reputation.
  • Click-Through Rates: The percentage of subscribers who click on links within your emails. High click-through rates show that your content is relevant and interesting.
  • Bounce Rates: The percentage of emails that are undeliverable due to invalid addresses or full mailboxes. A high bounce rate can negatively impact deliverability.
  • Spam Complaints: This metric tracks the number of subscribers who mark your emails as spam. A surge in spam complaints can significantly damage your sender reputation and hinder deliverability.

By regularly monitoring these metrics within your email marketing platform, you can identify potential issues early on. For example, a spike in bounce rates might indicate a problem with your list hygiene practices, prompting you to remove invalid addresses. Similarly, an increase in spam complaints might necessitate a review of your email content or sending frequency.

So, make data your friend! By consistently monitoring and analyzing your email deliverability metrics, you can fine-tune your strategies and ensure your emails reach the inbox.
