How to Enhance Your Cold Email Deliverability with Spintax

In today's fast-paced digital world, cold emailing remains an effective strategy for cold email outreach and networking. However, one challenge that persists is email deliverability—ensuring your message actually reaches the recipient's inbox and not their spam folder.

To improve email deliverability, many marketers and business professionals are turning to Spintax, a versatile email tool that improves email content.

In this article, we will explain what Spintax is and how it improves cold email deliverability, especially when sending spintax cold emails.

How Does Spintax Improve Email Deliverability?

What is Spintax?

Before diving into the benefits of Spintax, it's crucial to understand what it is. Spintax, short for "spinning syntax," allows you to create multiple versions of text by placing options within curly braces {}. These versions are separated by a vertical bar |.

For instance, you might write a sentence like:

{Hello|Hi|Hey}, how are you today?

Depending on your spintax program, one of the three greetings will be selected randomly for each email sent. This capability for variation makes Spintax an invaluable asset for anyone looking to improve email deliverability.

Key Benefits of Using Spintax for Email Deliverability

Now, let's delve into the specific advantages of using Spintax to enhance your email deliverability rates.

Avoiding Spam Filters

One of the main hurdles in improving email deliverability is bypassing the spam filters employed by Email Service Providers (ESPs) and other email providers. These filters scrutinize incoming emails for common spammy behaviors; one red flag is identical content sent to multiple recipients. Falling into the spam folder is risky when your emails appear too similar.

Utilizing Spintax in your email campaigns allows each email to have slight variations, tricking the spam filters into thinking each email is unique. This increases the likelihood of your emails avoiding the spam folder and landing in the recipient's inbox instead.

Enhancing Personalization

Personalization goes a long way when it comes to engaging the recipient. You can personalize email content at scale by employing spintax in your cold emails.

For example, the email body text can include spintax such as:

I came across your {company|organization|business}, and I'm impressed with {what you do|your operations|your work}.

Each version speaks to the reader slightly differently, increasing the likelihood of them engaging with your email.

A/B Testing for Effectiveness

Spintax also offers the advantage of easy A/B testing. Using different variations in your emails lets you determine which versions garner the most responses, opens, or click-throughs. This data-driven approach can be crucial for continually improving email deliverability over time.

How to Use Spintax in Your Cold Emails

Incorporating spintax into your cold email campaigns isn't just about adding a set of curly brackets and vertical bars; it's an art that requires strategic thinking.

Let’s learn how to craft compelling spintax variations for different parts of your email, such as the email subject lines, opening lines, body content, greetings, and calls to action (CTA).

Crafting Spintax for Subject Lines

The subject line is the first thing your recipient sees, significantly impacting your email open and response rates. Use spintax to create subject lines that capture attention yet feel personalized.


{{Hello|Hi|Hey} {First Name}, {Interested in a partnership?|Looking to collaborate?|Open for business opportunities?}}

This way, you have three different greetings and three different hooks, leading to nine unique subject line possibilities. It's a simple but effective way to improve email deliverability by avoiding spam filters that flag identical subject lines.

Spintax in Opening Lines and Greetings

Your opening line and greeting set the tone for the rest of the email. Use spintax to diversify how you greet your recipient and introduce your reason for reaching out.


{{Hello|Hi|Hey} {First Name}, {I came across your LinkedIn profile|Your work caught my eye|I'm impressed by your recent project}}.

By crafting such variations, you sidestep spam filters and engage your audience with a personalized opening line.

Body Content Variations

The body of your email should carry the meat of your message. Here, you explain why you’re reaching out, what you’re offering, and how it benefits the recipient.

Example of Nested Spintax:

I {read|came across} your {article|post} about {subject}. {I found it {enlightening|insightful}|It gave me {new perspectives|fresh ideas}}.

Nested spintax allows you to create even more variations by placing spintax within spintax. This increases the chances of your emails appearing unique to spam filters, further helping to improve cold email deliverability.

Crafting a Compelling CTA

The call to action is where you invite your reader to take the next step. Your CTA should be specific, direct, and action-oriented.


{Could we schedule a {call|meeting} for {this week|next week}?|Would you be {interested|open} to {discuss|chat} {further|more} about this?}

Each segment offers different options, making the CTA more personalized and encouraging action from the recipient.

Best Practices for Using Spintax

Utilizing spintax to improve cold email deliverability in cold email campaigns is a clever email strategy, but it's not a one-size-fits-all solution. To effectively employ spintax and reap the rewards of improving cold email deliverability, consider these best practices:

Keep It Natural

The primary objective of using spintax is to make your cold emails appear more organic and less automated. Therefore, your spintax variations should be coherent and conversational.

👎 Bad Example:

{Hi|Hey|Hello} {Sir/Madam|Customer}, {Buy|Purchase|Get} our {item|product|good} {now|today|immediately}.

👍 Good Example:

{Hi|Hello|Hey there} {First Name}, {Are you interested in|Would you like to know more about} our new {product|service}?

The second example not only reads more naturally but also serves to improve cold email marketing deliverability by evading spam triggers.

Choose Variations Wisely

Your spintax should be as relevant and targeted as possible. Aim to alter phrases that could mean the same thing but are phrased differently. This is especially crucial in the body of your spintax cold email, where the bulk of your email content resides.

👍 Good Example:

We offer {a range of solutions|multiple options|various services} to {address|tackle|solve} your {business needs|business challenges}.

Message Context

Keep sight of the message you are trying to convey. Your spintax variations should always remain aligned with the overall context of your cold email.

Perform A/B Testing

Always test your spintax variations to gauge what's resonating with your audience. A/B tests can provide invaluable data on which spintax combinations are most effective for achieving high open and click-through rates, and response rates.

Don't Overcomplicate

While inserting spintax for every other word is tempting, this could confuse your readers and make the email feel robotic. The best practice is to strike a balance: enough variations to improve cold email deliverability, but not so many that you compromise readability.

Know Your Audience

It's important to deeply understand your target audience before employing spintax. Variations that may work for one demographic may not work for another.


As we wrap up this comprehensive guide on how to improve cold email deliverability using spintax, it's essential to remember that the end goal is to make your cold emails as personalized and engaging as possible. Spintax allows you to do just that, offering flexibility in your messaging while ensuring you steer clear of spam filters.

Utilizing spintax effectively in your cold emails can make all the difference in whether your emails end up in the recipient's inbox or the junk folder. By incorporating spintax in the subject lines, body content, greeting, and call-to-action, you can increase your email's chances of getting noticed and acted upon.

To summarize, understanding what spintax is and how it can aid in improving cold email deliverability can go a long way in making your cold email campaigns successful. Always abide by best practices, test different variations, and, most importantly, ensure that your email content remains engaging and offers value to the recipient.

By employing these techniques and best practices, you're well on your way to mastering spintax cold email strategies and enhancing your cold email deliverability rates.

Incorporating spintax is not just a tactic; it's a strategy for long-term email success. So, start experimenting with spintax variations in your next cold email campaign and measure their differences!
