How Do You Improve Email Deliverability?

Aside from testing your email deliverability, your email marketing campaigns and efforts can benefit much from improving your email deliverability rate. Improving your email deliverability involves several key strategies and best practices that you can implement to increase the chances of your emails reaching your audience’s inboxes and avoiding being marked as spam.

Here are some great ways on how to improve your email deliverability:

Maintain a Clean Email List

A clean email list ensures your emails are sent to the right recipients. You can regularly clean your email list by removing inactive or invalid email addresses and using double opt-in methods to ensure subscribers genuinely want to receive your emails.

Create Quality Content

Content is at the heart of every marketing strategy. Hence, craft engaging and relevant content that provides value to your subscribers so they will often open your emails, bringing you to the forefront. Furthermore, do away with “spammy” language, excessive punctuation, or misleading subject lines.

Authenticate Your Emails

Implement email authentication protocols such as SPF (Sender Policy Framework), DKIM (DomainKeys Identified Mail), and DMARC (Domain-based Message Authentication, Reporting, and Conformance) to verify your domain’s legitimacy and protect against spoofing and phishing.

Use a Consistent Sending Schedule

Optimize Email Design

Your recipients access their emails via different devices, although statistics show that most of them use their phones to check emails. Ensuring that your emails are mobile-responsive, visually appealing, and easy to read makes it more convenient for your recipients, increasing the possibility of them engaging with your emails.  

Manage Complaints and Stay Compliant with Regulations

The law forces you to provide your subscribers a way to stop receiving emails from you. So, familiarize yourself with and adhere to email marketing regulations, such as the CAN-SPAM Act or GDPR (General Data Protection Regulation). Then, provide clear unsubscribe options and honor unsubscribe requests promptly.

Additionally, managing customer complaints effectively can help your brand maintain a positive reputation.

What Affects Your Email Deliverability Rate?

Several factors can significantly affect your email deliverability rate, determining whether your emails successfully land in your audience’s inboxes or get flagged as spam or blocked by email servers. 

First and foremost, the quality of your email list plays a crucial role; having a clean, engaged list with valid and active email addresses increases the likelihood of higher deliverability rates. It’s important to avoid purchasing email lists or using outdated contacts, as these practices can negatively impact deliverability.

Another critical factor is your sender reputation, which is assessed based on various metrics like email engagement rates (opens, clicks, replies), spam complaint rates, bounce rates, and overall sending behavior. Maintaining a positive sender reputation is essential for improved deliverability. Moreover, emails with relevant, valuable, and engaging content are more likely to reach the inbox. In contrast, those with spammy language, misleading subject lines, or excessive promotional content may be filtered out.

Recipient engagement is also a key factor; low engagement rates, such as low open or click-through rates, can signal to email service providers that your emails may not be relevant or desired by recipients, potentially leading to lower deliverability over time. So, you must provide your recipients with quality content and respect them by maintaining a positive tone that enables you to boost your engagement rates. 

Regularly monitoring and optimizing your email campaigns based on the mentioned factors can help you achieve better email deliverability rates and maximize the effectiveness of your email marketing efforts.

What Are Email Deliverability Test Tools?

Email deliverability test tools are software applications or online services designed to help email marketers assess and improve the likelihood of their emails reaching recipients’ inboxes rather than being filtered out as spam. These tools typically offer a range of features and functionalities to evaluate various aspects of email deliverability.

Some standard features found in email deliverability test tools include:

Inbox Placement Testing

These tools simulate the delivery of your emails to different email providers (e.g., Gmail, Yahoo, Outlook) to determine whether they land in the inbox, spam, or junk folder or are blocked entirely.

Authentication Checks

These tools verify that your email authentication protocols, such as SPF (Sender Policy Framework), DKIM (DomainKeys Identified Mail), and DMARC (Domain-based Message Authentication, Reporting, and Conformance), are set up and configured correctly. Ensuring proper authentication can improve deliverability and protect against spoofing and phishing attacks.

Blacklist Monitoring

Some email deliverability test tools monitor public and private email blacklists to check if your domain or IP address is listed. Being on a blacklist can significantly impact deliverability, so timely detection and resolution are crucial.

Delivery Speed Testing

These tools assess the speed at which your emails are delivered and flag any potential issues that affect delivery rates. They may also recommend optimizing delivery times based on recipient behavior and preferences.
