Acquisition Email is Marketing’s Unsung Hero

Prospecting in a privacy-first world? Harder than it seems. But with the right tools and channels  – like acquisition email marketing and modern acquisition email platforms – it can become much easier.

There’s a common misconception in the advertising world that we feel compelled to speak on. It has to do with email.

To some marketers, using email as a primary channel seems outdated. After all, email has been around longer than most other digital channels – including SEO, display ads, social media marketing, and (most obviously) CTV. The first email marketing campaign, if you can believe it, was sent in 1978 – preceding even the birth of the internet.

The legend goes like this: Gary Thuerk, a marketer at Digital Equipment Corporation, wanted to promote the company’s new DECSYSTEM-20 line of computers. Using ARPANET’s SNDMSG program, his assistant sent a message to roughly 400 recipients — the first known unsolicited mass email.

The email was clunky by modern standards: addresses bled into the subject line and body, and recipients immediately complained. An ARPANET representative told him never to do it again.

The campaign also generated $13 million in sales — and thus, email marketing was born.

Acquisition email marched onward. With the rise of consumer ISPs like AOL, Prodigy, and CompuServe, by the ‘90s, companies were rampantly sending out “spray and pray” emails before good spam filters even existed. 

Low implementation costs and the quick reach of email meant easy money for marketers. In fact, marketing emails generated by far the most ROI with the channel in the early 2000s. For advertisers, the appeal was obvious – and the strategy worked, for a while.

Disregard for their audience also meant marketers sending out annoying emails to the vast majority of (uninterested) prospects. These marketing email blasts led directly to regulations, including the 2003 CAN-SPAM Act in the US.

Today, all email platforms boast robust spam filters, the CAN-SPAM Act protects recipients from the worst actors in commercial email, Apple launched Mail Privacy Protection in 2021 to protect user IP addresses, and Google instituted new spam rules for bulk email senders in 2024.

Given all the effort to protect unsuspecting users from spam emails, marketers have developed another misconception: email is not an effective channel for acquiring new customers.

Block lists, spam traps, sad open rates, even sadder click rates – that’s what comes to mind when most people think of cold emails. Personalized, customer lifecycle emails? Sure. But acquiring new customers?

But not everything is as it seems when it comes to email.

After all, email still boasts the highest ROI of any channel – and it can be just as effective for acquiring new customers as it is for re-engaging old ones. When done correctly, acquisition email is still a powerful (and compliant!) way to reach new prospects. 

Once you focus on the importance of high-quality, ethically sourced data (like Stirista’s) – no purchasing cold email lists! – then you can truly find where acquisition email shines.

The real advantages of acquisition email

Many marketers are familiar with email’s typical strengths – high ROI for every dollar spent, lifecycle marketing efforts, almost-guaranteed appearances in inboxes – but don’t quite know about the benefits of acquisition email marketing solutions for growth and scalability

We’ll break it down for you.

Attribution that’s nearly totally see-through

Unlike social or paid ads that can rely on algorithms for placement – a lot of the time, marketers don’t even know where their ads have landed and who’s seeing them – emails boast clear, direct metrics.

You can choose (and know) in which exact inboxes you’ve landed. As a result, you also get a direct line of communication to your prospects. This is especially valuable in B2B, where buying cycles are long and multiple stakeholders are involved.

Hyper-segmented capabilities and enhanced personalization

Modern acquisition email platforms allow segmentation and personalization based on role, industry, or behavior – far beyond first-name tokens.

By tailoring content, you can generate demand more effectively than with generic outreach. And you can personalize both copy and creative – based on location, age, intent, and any other identifier.

Measurable data, enhanced attribution, better optimization

Every email interaction (open rates, click-throughs, conversions) provides measurable data. This lets marketing teams test subject lines, CTAs, and content formats, and then double down on what works, continuously improving demand generation ROI.

The most cost-effective solution

Compared with paid media, acquisition email can be cheaper per lead, especially if you have a high-quality prospect list. It’s essentially the fastest way to get to direct reach, and direct sales, too.

Best practices for acquisition email

As we’ve mentioned, spray-and-pray doesn’t quite work anymore – and by quite, we mean at all.

Let’s go over some acquisition email best practices for building targeted lists, personalizing outreach, and integrating acquisition email into a multi-channel strategy to warm up prospects before sending some emails they will likely resonate with.

Compliance comes first

• Emails might be “cold,” but your prospects should be warmed up.

• Use co-registration partners, gated content, or events to build lists ethically. And use data partners like Stirista to verify who may be interested – prospects who have been searching for you or your products.

• And of course, comply with Google’s bulk email sender requirements, the CAN-SPAM Act, and other regulations set out by email clients and general best practices. Nobody wants to be the one who mass-blasts an email that ends up bouncing or landing in the junk folder.

Don’t forget targeting and segmentation

Tailor emails to specific industries and use intent signals. Website traffic, ad exposures, social media engagement, and more can all be signals your prospects know about you – and are interested in what you’re offering.

These intent signals should guide your outreach efforts and also enhance your personalization.

Go beyond “first name” personalization

But don’t go too far. After all, in acquisition, these aren’t loyal customers (yet) – they’re prospects. 

Deliver immediate value

Whether that’s education material for an awareness campaign, or leaving your prospect with a discount code or a different perk. 

Testing and optimization

Always iterate on your process. A/B testing personalization, offers, different segments, and more can increase engagement over time.

Let’s go, email

As a channel, email almost feels like an afterthought, especially with so many other shinier channels to play with.

But there’s a reason email is the oldest digital channel that’s still around today. There’s a reason ID solutions rely on hashed emails. There’s a reason emails are the go-to for loyalty and lifecycle marketing.

They work.
