Top Tools & Strategies to Improve Email Deliverability Rates

Getting your messages to the primary inbox is much more than writing stellar emails and hitting the send button. This is because even when the emails get delivered, spam filters may drive them to other email folders your recipients cannot access easily.

Many businesses face this challenge despite their efforts to improve email deliverability rates – and it not only harms the brand reputation but ruins business growth, too.

This is why we’ve created this guide blog post. In this detailed article, we’ll show you what strategies and software tools can help you improve your email deliverability rates, and how you can get started today.

12 Strategies to Help You Improve Email Deliverability Rates

In this section, we go through essential strategies to land in the inbox every time, and in the next section, we’ll show you which tools can help implement these strategies.

1. Authenticate your email domain

Email authentication involves the preliminary steps to build the right email infrastructure and ensure security using defined protocols. It protects your emails and subscribers from spam and phishing attacks.

When cybercriminals use your emails for malicious purposes, affected users may get frustrated and mark your emails as spam. This sends negative signals to mailbox providers, causing them to reject or redirect your emails with spam filters.

Without proper email authentication protocols, you cannot prove your emails’ legitimacy, which can harm your deliverability. The three major authentication protocols include the following.

1. Sender Policy Framework (SPF): This protocol allows receiving email servers to accept incoming emails from authorized senders.
2. DomainKeys Identified Mail (DKIM): This protocol uses digital signatures in email headers to validate the integrity of a message.
3. Domain-based Message Authentication Reporting and Conformance (DMARC): This protocol enables domain administrators to publish policies for handling incoming emails. It combines both SPF and DKIM protocols.

Smart implementation of these email authentication methods reduces your spam, prevents phishers from hijacking your emails, and protects your brand reputation.

2. Use a dedicated IP address

A shared IP address may be ideal for low-budget or new senders, and it’s easier to maintain a good domain reputation if other domains have good records. The downside, however, is you have less control, and the activities of other domain administrators can affect your sender reputation and domain performance.

This can cause email servers to blacklist your emails since you’re likely sharing the same IP address with spam senders.

On the other hand, a dedicated IP address, though expensive, gives you more control over your sender reputation and prevents receiving email servers from blacklisting your emails. Although not all email senders with shared IP addresses have malicious intentions, you have more flexibility and customizability over your email domain management when you use a secure address not affected by other senders’ activities.

3. Keep your email list clean

Usually, your email list contains a variety of email addresses with real and fake users. And even among your true subscribers, some may no longer have interest in your brand over time, so sending emails to these groups may seem unnecessary.

Email list cleaning involves removing inactive or outdated contacts while keeping subscribers willing to continue with your brand. Sending emails to incorrect or invalid email addresses can lead to hard bounces. Moreover, users who have lost interest in your brand may move future emails from you to the junk folder since it no longer appeals to them.

So, cleaning your email list regularly ensures your emails are sent to the right recipients, thus reducing bounce rates and spam scores, and improving your deliverability. Here are a few tips to help you ensure a clean email list:

• Remove or merge duplicate email addresses
• Use simple opt-in forms with clear fields
• Delete spam email addresses
• Correct possible typos in the addresses
• Re-engage inactive users and remove those who no longer indicate interest in your brand

4. Write helpful and non-spammy content

Sending helpful, relevant, and engaging emails is one way to maintain high deliverability rates, as subscribers will receive emails that appeal to them. They can also move your emails from the junk folder to their primary inboxes, thus sending positive signals to mailbox providers.

So, even with a clean email list, capturing your existing customers’ attention with timely, relevant, and appropriate content is necessary.

Sometimes, spam filters can prevent your emails from getting to the inbox if they detect malicious patterns in your content. Therefore, you should always check your emails to remove spam trigger words or patterns that can cause these programs to flag your emails as spam.

Some tips for crafting helpful emails include the following:

• Avoid using too many exclamation points or special characters
• Correct grammatical or spelling errors
• Avoid using all-caps
• Create a balanced image-to-text ratio
• Do not use hard-to-read fonts or colors
• Avoid adding too many links

5. Use clear and engaging subject lines

Your email subject line is the first thing your recipients see before opening your email. It gives a concise overview of the email and compels your users to click and read through.

Poor subject lines can cause recipients to ignore or flag your emails as spam. According to stats from Gitnux, 69% of recipients report an email as spam based solely on the subject line.

So, if your subject line and preview text are not clear, compelling, and relevant, your recipients can move it to the spam folder, which can harm your deliverability rate.

6. Make unsubscribing easy

No matter how valuable your emails are, they may not always be the right fit for every user. Moreover, a segment of your audience may lose interest over time, and this is normal because as customers’ needs change, their desires and interests also change.

Moreover, your customers may not stay with you forever, so it’s important to create options that let them choose how to receive your emails. You can segment your customers based on how they prefer to receive your emails:

• Those who want to get all your brand updates
• Those who need only necessary updates
• Those who want to stop receiving updates from you

Adding an unsubscribe link or a preference center in your email – preferably in the footer – can help you filter out contacts whose priorities have changed, thus helping you create smart segments. When subscribers find it difficult to locate your unsubscribe link, they can move your emails to the spam folder out of frustration, so they don’t see future updates from you.

The unsubscribe option can also serve as a way to get customer feedback for improving your email marketing strategy. When inactive contacts can leave your brand easily, your emails will be less likely to be flagged as spam. This improves your sender reputation and, consequently, your deliverability rate.

7. Warm up your email account

Email warm-up is usually ideal for new or inactive email accounts, and it entails sending emails gradually and increasing your frequency until you get to your ideal sending volume.

Usually, recipients may not trust a new or dormant brand, so flooding your subscribers with too many emails can drive you to the junk folder.

Therefore, starting slowly – especially for cold email outreaches – is important until you have achieved a good sender score. You can pick a consistent sending schedule from here and stick to it. And since you’re using a new domain, it is advisable to have a consistent sender name to avoid confusing your recipients.

An improved sender score indicates your emails are from a legitimate source. As customers get familiar with your brand over time, your engagement rate will increase, thus increasing your sender reputation and, eventually, your deliverability rate.

8. Use a double opt-in subscription system

A double opt-in system involves sending a notice to new subscribers to confirm the validity of their email addresses before adding them to your contact database. It is a part of the strategies involved in cleaning your email list and ensuring only valid addresses are added.

This process prevents fake addresses that may increase your email bounce rates and hurt your sender’s reputation. Moreover, you have more qualified contacts who will engage with your emails and are less likely to flag you as spam.

9. Segment your email list

Email segmentation involves fragmenting your contact list into smaller groups based on pre-defined attributes or characteristics. Your customers have varying preferences, so putting them all in a single category and sending the same emails can make them lose interest in your brand, since most emails may be unwanted or unsolicited.

Proper email segmentation involves using certain attributes to craft personalized emails that appeal to different segments of your audience. Your email segments can be demographic, behavioral, geographic, or psychographic, depending on your business needs and customer preferences.

An excellent segmentation strategy can improve engagement rates and help you build healthier customer relationships. As customers interact with emails that appeal to them, mailbox providers perceive your emails as genuine and will prevent them from getting hit by spam filters.

10. Do not buy email lists

Having a large subscriber base is great. However, the quality of your contacts is more important than the quantity. In other words, 500 serious buyers are more important than 5,000 visitors who have no interest in your brand. Business owners who buy email lists bypass building qualified leads from the ground up, hoping to have a large contact list that will eventually increase sales.

While this may seem like a faster route, there are certain disadvantages with it:

• Your emails will be flagged as spam
• It can increase your unsubscribe rate
• Your email service provider may place restrictions on your domain
• You’re violating data protection laws
• It can reduce your sender’s reputation
• You end up sending emails to recipients who don’t trust you and won’t buy from you

These factors can create poor customer experiences, thus leading to low engagement rates and high spam scores. Eventually, your email address may get blacklisted since your emails are unwanted and don’t appeal to your contacts.

11. Comply with anti-spam laws

Generally, antispam laws do not directly impact your email deliverability. However, they provide certain requirements and regulations that enable you to create helpful and appropriate email content. They also protect your subscribers from receiving unsolicited emails, thus helping you build healthy customer relationships.

The major requirements of the anti-spam laws include:

• Don’t use deceptive subject lines
• Include a valid physical address that shows your location
• Identify clearly that your message is an ad (if it is)
• Avoid using false or misleading header information
• Include a clear unsubscribe link to help users opt out of your emails easily
• Honor all opt-out requests promptly

12. Use a reliable email service provider (ESP)

An email service provider is usually a software application designed to help you craft and send emails at scale. It supports robust email marketing features that enable you to run successful campaigns. These features may include marketing automation, email verifier, list segmentation, reporting and analytics, and customizable email templates.

There are several ESPs with varying functionalities, but your choice largely depends on your business needs and size, so it’s important to pick tools with unique features to meet your brand goals and needs.

A poor email service provider can hurt your deliverability, as it may lack advanced features to help you deliver your emails to your subscribers’ inboxes. It may also lack important functionalities enabling you to segment and merge your lists to create personalized campaigns.
