Wish you smooth sailing on your email deliverability journey—a place that comes with its own set of rules, tips and tricks, and dynamics to keep learning about all the time. When you apply these deliverability best practices, you will ensure your email always gets delivered to the recipient’s inbox and create engagement.

Understanding Email Deliverability

When it comes to email deliverability, it’s not just about sending out messages. It’s about ensuring that your well-crafted emails end up in your subscribers’ inboxes. This involves using specific strategies tailored to your target market, constantly improving your approach, and focusing on engaging your audience.

Evaluating email deliverability is crucial for the success of your campaigns, as it determines how well you can connect with your audience and drive conversions.

What Is Email Deliverability?

Email deliverability is about ensuring your emails land in the recipient’s inbox and not their spam folder. This is vital for email marketing success. One way to measure this is through the inbox placement rate (IPR), which shows the ratio of your sent emails that reach the inbox versus those marked as spam. A high IPR leads to better open rates and engagement for your email marketing efforts.

Email Deliverability vs. Email Delivery.

There’s a difference between “email delivery” and “email deliverability.” Email delivery means the email leaves your server and reaches the recipient’s email server, but it doesn’t guarantee that it will end up in their inbox; it could go to the spam folder.

Email deliverability refers to the percentage of emails that land in the recipient’s inbox. Email delivery focuses on getting the message to the server, while email deliverability asks whether the message has made it to the recipient’s inbox or ended up in the spam folder.

The Email Deliverability Puzzle

Getting high deliverability is not as easy as one might think, and it’s not just about avoiding the spam folder. It’s about how to be more trusted by users, how to make them open the letters excitedly, and how to meet all the new technologies and rules in emails.

The Technical Foundation: Email Infrastructure

To ensure that your emails are delivered properly, it’s important to have the right technical framework in place to confirm that the emails you receive are authentic. This involves several elements that, when properly coordinated, help rebuild trust between your domain and the ISPs.

• Dedicated IP Address: It’s important to have a dedicated IP address for email marketing, as it gives you full control over your sender’s reputation. Gradually increase activity on the IP to avoid being blacklisted or marked as spam.
• Sender Policy Framework (SPF): SPF is like an email passport. It specifies which IPs can send mail to a domain, minimizing spoofing and enhancing deliverability.
• DomainKeys Identified Mail (DKIM): DKIM acts like a signature for emails, ensuring they remain unchanged and haven’t been tampered with. The recipient’s server checks the DKIM signature to confirm the message’s integrity.
• Domain-based Message Authentication, Reporting, & Conformance (DMARC): This paper explains how DMARC addresses the issues of SPF and DKIM. It allows you to set a policy for handling mail that fails SPF or DKIM checks and provides detailed reports on your domain’s email usage.

The Reputation Game: Building Trust with ISPs

Your sender reputation greatly impacts your email’s success. ISPs monitor this reputation, and poor ratings can lead your emails to end up in the spam folder, despite other factors being perfect.

• Consistency is Key: Maintain a consistent sending frequency to avoid triggering alarms with ISPs. Start with a specific sending frequency and gradually increase the volume as confidence is built with ISPs.
• Engagement Metrics Matter: ISPs consider how recipients interact with emails. High open rates, CTR, and low spam complaints improve your reputation. Deleted or marked as spam emails harm your sender’s reputation.
• List Hygiene: Regularly clean your email list by removing bounced addresses and inactive subscribers to maintain your reputation.

How the ISPs Block Spam Emails

ISPs decide where your email goes, using filters to block spammers and ensure real messages reach the right inboxes, helping email marketers improve deliverability.

1. Spam Filters: ISPs search for specific words, phrases, and content types in emails to identify spam, like “free,” “guaranteed,” or excessive use of symbols.
2. Blacklisting: If your IP address or domain is labeled as a source of spam, it is put on a blacklist, which ISPs use to stop emails from reaching the recipient’s inbox.
3. Authentication Checks: SPF verifies your permission to send emails, DKIM confirms the email’s authenticity, and DMARC ensures the “from” field is genuine. Missing these checks could lead to your email being marked as spam.
4. Spam Complaints & Feedback Loops: When emails are marked as spam, ISPs recognize that recipients don’t want them. Managing spam complaints is crucial for maintaining good delivery rates and sender reputation.

Crafting Emails That Deliver

When you are ‘squarely planted’ on the technical side of things and have a sound reputation established, it is now time to focus on profit mechanics, of course. Any fully authenticated message originating from the most reputable source can still land in the spam inbox due to the contained material.

Subject Line Optimization

Your subject line is your first message that the recipient sees, so it must be attention-grabbing but not too over-the-top spammy. Here are some tips:

• Do not use capital letters very often, and do not use a lot of punctuation.
• Avoid phrases such as ‘free,’ ‘limited time offer’ or ‘guarantee.’
• Get to the point—preferably in 40 characters or underneath.
• Personalizing bulk emails with the recipient’s first name or specific names can increase open rates, but too much personalization may come off as ‘creepy’.

Content That Converts

The body of your email should match the promise of your subject line and resonate with your audience:

• Balance text and images: Having many images can cause spam issues. It is recommended to use supplementation with both approaches.
• Alt text for images: Another best practice is to always include alt tags so that at least you get some sort of results if images are not being shown.
• Avoid embedding forms: Oh no, what do you do when customers want to fill out forms in their e-mail? The answer is, don’t do that; link to a landing page instead.
• Personalize the content: Segment your emails according to the data captured from the subscribers and their level of activity to raise the level of personalization.

Make It Mobile-Friendly

The open rate for email now reveals that over 50% of these emails are opened and read on a mobile device. Make your e-mail optimizable for every possible device, and always place the key information—the main message and the CTA button—right at the top of the message.

Segmentation and Personalization

Gone are the days of mass emails. Subscribers now expect personalized content tailored to their interests, which boosts email campaign effectiveness and reduces spam complaints.

• Segment your audience: Segment your email list by age, region / geo-location, or previous and current purchases, as well as the level of activity.
• Personalize beyond the name: Rather than just {{First_Name}} why not create dynamic content based on the purchase history, behavior, or preferences?

Advanced Personalization

• Recommend products based on the recipient’s previous purchases.
• Send triggered emails: For example, a cart abandonment reminder is a highly effective, personalized follow-up.
• Adjust send times based on subscriber interaction history to maximize engagement.

Testing and Optimization: A Continuous Process

Deliverability is not just a one-time process that you can perform and forget about it. It needs constant practicing and fine-tuning to insistently enhance your chances of success. Here are some testing strategies to implement:

A/B Testing

Experiment with different aspects of your emails—such as subject lines, sender names, content formatting, CTA buttons, and timing—to see what elicits the right response from subscribers. Reflect on these factors to continuously improve your strategy.
