What Are The 5 Proven Strategies To Enhance Email Deliverability

Asha Sharma on June 24, 2024 in Campaign Management

In the current race of talking to each other, email still prevails as an indispensable means of communication for businesses and users. Whether you’re sending out newsletters, special offers, or important news, the success of your email’s deliverability depends on one main thing: singling out whether or not they reach the people you wanted to send them to.

ReturnPath reports that 1 in 5 emails doesn’t make it to the inbox, which can seriously affect how well your marketing works. However, what does the process of sending an email look like? The essence is that your email is delivered to a recipient’s inbox successfully instead of being tagged RE as spam or not getting to them. Sounds simple, right? Well, not really.

The fact that email deliverability issues keep changing and spam filters are becoming more perceptive makes it challenging to ensure that your emails go through smoothly and do not end up in people’s junk or spam folders.

What is email deliverability?

Email marketing deliverability ensures that your messages indeed reach your subscribers’ inboxes. It’s similar to the measure that some marketers apply to ensure that their email campaigns can be delivered to their subscribers` inboxes without any obstacles like ISPs rejecting them, too many bounces or spam tools, or even without looking at them by the user because of a spam tray.

However, some factors may damage your email deliverability issues, such as using the free email address, not having proper authentication, not confirming when people sign up, not getting any response from the subscribers, using short links, or not making subscribers unsubscribe effortlessly.

How to increase email deliverability?

The success of your email marketing campaign ultimately depends on how you improve email reputation and build a strong, long-term relationship with your audience.

Here are some five email deliverability tips and best practices:

  1. Implement domain authentication through SPF, DKIM, and DMARC.

    Support protocols such as SPF (Sender Policy Framework), DKIM (DomainKeys Identified Mail), subscribers main-based Message Authentication, Reporting, and Conformance) can be used to conclude that the sender authorizes the messages and are not counterfeit or contrasting emails. SPF takes care of ensuring just the servers that are authorized to send emails on behalf of your domain.

    At the same time, DKIM adds a digital signature to your emails to assure their integrity, and DMARC, as an extra precaution, contains policies for handling any emails that fail the authentication test. This way, you keep your email with a chance of being seen, and you don’t have the probability that it might be ‘marked as spam.’

  2. Monitor sender reputation and blacklist status regularly.

    Your sender reputation, assessed using metrics like email resonance, constrained rate, and spam trap touches, drives a great deal of email deliverability. Constantly observing your sender reputation and blocklist status makes it possible for you to detect any anomalies faster and find strategies that solve them.

    Apply aids that increase email deliverability or services that can show your impact across various email networks and react immediately to the negative tendencies and the decline in the reputation.

  3. Eliminate spammy language from your email content.

    Content is important in inboxing the right info from which your mailing lists can benefit. When SPAM emails have been designed bashing, excessive amounts of promotional phrases, and misleading subject lines, these are more very forward-looking to put spam filters off.

    Well-done mail delivery can be achieved by creating well-composed and simple content in the message and tailoring it to make it relevant to the recipient, which adds value. There is no need to use all caps every time or exclamation marks. Rather than this, determine your ultimate goal, focus on teaching useful information to your audience, and foster unique relationships with your community.

  4. Organize your email list into segmented groups.

    Segmentation enables you to spend wisely and has the potential to create a heightened level of personalization that improves email deliverability to resonate with specific audience segments. By splitting your email list into targeted segments according to demographics and customer purchase history or engagement rates, you will guarantee that you are sending more individual and relevant content that, in retrospect, creates a higher percentage of open rates and clicks. Besides, segmentation assists in minimizing the risk of submarines receiving emails unrelated to them, reducing the chance of them marking your messages as spam.

  5. Continuously track performance metrics

    You can track how far your email campaigns have achieved their objectives by monitoring open rates, click-through rates, unsubscribe rates, and bounce rates. Hence, through monitoring these data, key performance indicators can be determined, from which a shift in strategies can be sought, and marketing campaigns could be optimized for better results.


Implementing domain authentication, monitoring sender reputation, optimizing content, segmenting your email list, and tracking performance metrics will help improve email deliverability and, thus, maximize the potential of your communication processes. Recognize that email deliverability is a continuous duty, not a one-time check, which demands regular observation, adaptation, and improvement.
