Understanding Email Deliverability Tools

Before we get to the email deliverability tools, let’s get on the same page. We have to understand email deliverability and why tools are important. 

What are email deliverability tools?

Email deliverability tools are software or services that help businesses ensure their marketing emails reach their intended recipients’ inboxes. Email deliverability tools typically offer features such as email verification, spam testing, and analytics to optimize email campaigns. 

By using email deliverability tools, businesses can improve their sender reputation, increase the chances of their emails being delivered, and ultimately enhance their email marketing effectiveness.

What do email deliverability tools do?

Email delivery tools are designed to optimize the delivery of marketing and sales emails. 

These tools offer a range of features to improve deliverability, including:

  • Email authentication
  • Email validation
  • List management
  • Spam testing
  • Email warmup 

By using these email deliverability tools, businesses can give their emails a leg up and reduce the likelihood of them being marked as spam. 
Additionally, email delivery tools can provide data and insights to help businesses understand how their email campaigns are performing and identify areas for improvement.

What Makes an Email More Deliverable?

The defenses forged by email servers use a lot of factors to determine how deliverable your email is. 

These make up your sender reputation. Think of it like your report card. You’ve gotta do well in every facet if you want to maintain a stellar GPA! 

do you pass the email deliverability tools test? 

Are you sending from an authenticated account? 

Is your content relevant? 

Are you sending consistently? 

Are you respecting opt-outs?

So, what are you being graded on?

Authenticated Senders

Email authentication is a set of techniques and protocols designed to do two things: 

  1. Prove that sender is who they say they are 
  2. Prove that the email wasn’t messed with on its journey from point A to point B. 

Emailing your leads without these authentications set up is like trying to board a plane without your ID. 

Authentication techniques include: 

  • SPF (Sender Policy Framework): This allows the owner of a domain to specify which IP addresses are authorized to send email on behalf of the domain.
  • DKIM (DomainKeys Identified Mail): This is a digital signature to authenticate the sender of an email and ensure that the message has not been altered during transit.
  • DMARC (Domain-based Message Authentication, Reporting, and Conformance): This allows domain owners to specify how email servers should handle messages that fail SPF or DKIM authentication checks.

You can get these set up in your email client and DNS settings.

Relevant Content

Your emails have to actually be interesting to the people you’re sending them to. 

This is a surefire way to increase your open and engagement rates and reduce your spam complaints. 

Figuring out who on your big list of leads is interested in what can seem like a tough task. Keep reading to learn how easy it actually is with Customers.ai’s tools!

Consistency

You want to be a familiar, friendly presence in the inboxes of your leads. 

Sending emails on a consistent basis ensures you stay on their mind.

Email Volume

Consistency doesn’t mean flooding their inbox everyday. Overwhelming people with tons of emails gets you a one-way ticket to the spam folder.

Respect Opt-Outs

When somebody unsubscribes, just let ‘em go! Continuing to email people who have asked you to stop is only good for one thing: destroying your send reputation.

Best Practices for Improving Email Deliverability

Email marketing is a potent tool for businesses. However, the real challenge lies in ensuring that your emails successfully land in the inboxes of your target audience. Let’s look at five fundamental best practices for improving your email deliverability:

  • Maintain a Pristine Email List: Regularly cull your email list to remove dead or fake email addresses. This proactive upkeep ensures that your messages find their way to engaged recipients who are more inclined to interact with your content, elevating your sender reputation and bolstering deliverability.
  • Harness Email Authentication: Incorporate robust email authentication protocols such as SPF, DKIM, and DMARC to authenticate your domain and thwart email spoofing. These authentication measures help Internet Service Providers (ISPs) recognize you as a legitimate sender and improve the chances of your emails landing in the inbox.
  • Craft Irresistible Email Content: Make your content resonate with your target audience and focus on personalization. Personalized emails don’t just add value to your recipients, but they also can amplify engagement and signal to ISPs that your emails are trustworthy. But be aware of spam-like language or deceitful tactics, as these can trigger spam filters, jeopardizing your deliverability. 
  • Vigilant Monitoring and Data Analysis: Regularly scrutinize your email performance metrics – open rates, click-through rates, and bounce rates. This analysis enables you to unearth potential issues within your campaigns and helps you to make informed, data-driven decisions aimed at improving your deliverability over time.
  • Adhere to Email Regulations: Adherence to email marketing regulations is essential. Conform to stipulations such as the CAN-SPAM Act (for the United States) and GDPR (for the European Union). Ensure there are transparent opt-in and opt-out mechanisms for recipients and honor their preferences concerning email communication. Compliance with these regulations not only ensures legal compliance but also nurtures trust with your audience and garners favor with ISPs.

By diligently implementing these best practices, businesses can elevate their email deliverability, intensify engagement with their target demographic, and ultimately augment the efficacy of their email marketing endeavors.

Choosing the Right Email Deliverability Tool

When it comes to optimizing your email marketing efforts, selecting the perfect email deliverability tool is a critical decision for businesses. With a multitude of options at your disposal, you want to make a well-informed choice that suits your unique needs and goals. 

Here are some key factors to consider when evaluating and choosing the most suitable email deliverability tool:

1. Budget Considerations: To kick things off, it’s important to take a close look at your budget. Email deliverability tools come in a wide range of pricing models, ranging from affordable or even free options to premium solutions with advanced features. Assess how much you can allocate to this aspect of your marketing strategy.

2. Size of Email List: The size of your email list is a crucial factor in making the right choice. Some tools are better suited for smaller to medium-sized lists, while others are designed to handle larger-scale email campaigns efficiently. Make sure that the tool you select can comfortably handle your current list size and has room for growth as your audience expands.

3. Feature Set: Email deliverability tools offer a variety of features, including email verification, spam testing, analytics, A/B testing, and more. Pinpoint the specific features that align with your objectives. For instance, if improving open rates is a top priority, opt for a tool that provides robust A/B testing and analytics capabilities.

4. Integration Compatibility: Consider whether the email deliverability tool can seamlessly integrate with your existing email marketing platform, customer relationship management (CRM) software, and other crucial tools in your tech arsenal. Integration simplifies data flow and streamlines your marketing processes.

5. Deliverability Reputation: Take the time to research the tool’s reputation for email deliverability. A reputable tool should have a track record of helping businesses maintain high sender scores and successfully get their emails into recipients’ inboxes. Look for user reviews and real-world case studies to gauge its effectiveness.

6. Customer Support: Evaluate the level of customer support and training provided by the tool’s vendor. Reliable customer support can be invaluable when you run into technical challenges or need guidance on maximizing the tool’s potential.

7. Trial Period: Whenever possible, opt for a tool that offers a trial period or a free version with limited features. This allows you to test the tool’s compatibility with your specific needs and workflow before committing to a subscription.

8. Scalability: Keep an eye on your long-term goals. Ensure that the chosen tool can adapt and scale alongside your business as your email marketing campaigns grow and evolve.

The process of selecting the right email deliverability tool can and will significantly influence the success of your email marketing strategies. By carefully considering your budget, list size, desired features, and other essential criteria, you can make an informed choice that aligns with your business goals and enhances your email deliverability.

The Top 7 Email Deliverability Tools for 2024

Email Deliverability Tool #1: Targeted Customer List Generators 

You don’t want to waste your time and risk your send reputation emailing just anybody. 

You want to email people who are actually interested in what you’re selling. 

Casting a wide net made some sense in the past when it was really difficult to tell who was a real-deal potential customer and who wasn’t. 

But now, thanks to Customers.ai’s Unicorn X-Ray technology, all you have it takes is a few clicks. 

Learn how to turn on X-Ray

Here’s how it works: 

  1. Create an automation 
  2. Click email
  3. Pick X-Ray Website Visitor as your input Trigger
  4. Set your conditions

And there you go! 

The URL could be a pricing page, a specific item page, or any other high intent page. 

This lets you send extremely relevant emails to people who are extremely interested in your business! 

Email Deliverability Tool #2: Email Validators

High bounce rates are a huge 🟥red flag🟥 to email service providers. 

If a lot of your emails are constantly bouncing back, Google and the rest of the email clients will think you’re just tossing spaghetti at other people’s inboxes and seeing what sticks. 

Email validators are an essential email deliverability tool. 

Launching an email campaign without a validator is like driving in the rain without your wipers on.

That’s why we built one into our automation. 

Some validators only look for negative signals. This leaves you vulnerable to high bounce rates. 

Our validator looks for actual confirmation that an email is live. This offers your reputation the best protection. 

Email Deliverability Tool #3: Customers.ai’s Signs of Life Detector 

Starting with a targeted list and filtering it with an email validator are great steps towards protecting your domain reputation and finding the right customers. 

But one more filter is key to stratospheric success. 

That’s why we built our newest email deliverability tool: the Signs of Life Detector

This groundbreaking tool automates the best strategies for getting your emails into your customers’ inboxes. 

Here’s how it works: 

  1. We send out an ice-breaker email
  2. If someone engages, we detect that and automatically follow-up
  3. If they don’t engage, we don’t bother sending anymore emails

It sounds counterintuitive but it’s true. 

Unlike other marketing channels, less really is more. There are huge potential downsides to sending too many emails to the wrong people. This is a chart of one customer’s email performance last year:

Chasing after people who don’t engage with or open your emails is the wrong strategy. 

S.o.L.D. helps you focus on the people that demonstrate interest in your emails. Those are the people that actually matter

They’re the hot leads you can close fast!

Email Deliverability Tool #4: Round Robin Senders

Email Service Providers try to relegate bulk-sent emails to the promotions folder. 

That’s not where you want to be. You want to be in the inbox. The best way to avoid the cautious gaze of the ESP is to not send too many emails from any one account. 

That’s why a Round Robin Sender is an essential email deliverability tool. With Customers.ai, you can set it up so your campaign sends the email from several different accounts!

This way you avoid tripping the signals that stop your emails from getting to the promised land!

Email Deliverability Tool #5: Interval Sender

Sending too many emails too fast is like standing outside the ESP’s office with an “I’m Spam!” sign. 

People often make the mistake of doing too much too fast. Using an email deliverability tool like an interval sender does two things: 

  1. It helps your accounts go unnoticed by ESPs. 
  2. It gives you a steadier stream of leads for your sales team. 

It’s easy to set your intervals in Customers.ai’s system. 

  1. Click on the “Integrations” tab on the navigation bar. 
  2. Click the pencil icon in the actions column.
  3. Select the interval you’d like. We recommend 10 minutes between emails!

Email Deliverability Tool #6: Paid Email Domain

You might like free email accounts like yourname@gmail.com or yourname@yahoo.com because, well, they’re free.

But email service providers will shut those accounts down the second they catch a whiff of bulk sending.

Google and other providers will give users who pay for accounts, like Google workspace, much more leeway.

This is one instance where you get a lot for paying more.

Email Deliverability Tool #7: Automatically Customized Email Content

Avoid getting flagged for sending the same email too many times by, well, not send the same email too many times! 

That doesn’t mean you have to reduce your sending even further. Instead, use one of Customers.ai’s email deliverability tools: easily customizable email templates and our AI email writer.

Personalization email deliverability tool

Putting these customizations in prominent places like the subject line, preview, or beginning of the email helps to convince the ESP that every email is unique and individual. 

Even better, that’s because each email is unique and individual. Your potential customers will feel the same way.
