- Tension: Email remains consumers’ preferred marketing channel while simultaneously becoming the primary source of their marketing frustration.
- Noise: Marketers obsess over delivery rates and optimization tactics while missing why 40% of consumers now unsubscribe from brand emails weekly.
- Direct Message: Email’s dominance doesn’t grant permission—brands that treat preference as entitlement discover the difference when consumers start marking messages as spam.
To learn more about our editorial approach, explore The Direct Message methodology.
Back in 2014, a survey by Message Systems showed that 25% of respondents preferred marketing through email. Today, with 4.48 billion email users globally, that preference has become both an opportunity and a trap.
Email marketing now generates an average ROI of $36 for every dollar spent—making it the most effective digital marketing channel. Yet 40% of U.S. consumers now unsubscribe from brand emails at least once weekly, and nearly 20% skip the unsubscribe button entirely, simply marking messages as spam instead.
This contradiction defines the current state of email marketing: consumers want it, demand it, and increasingly hate it.
The channel everyone wants until they don’t
Sixty percent of consumers prefer receiving brand communications via email over any other channel. Nearly 93% check their email daily, with 42% checking three to five times per day.
Mobile devices ensure that inboxes travel everywhere consumers go—email marketing messages find their audience whether they’re commuting, working, or standing in line for coffee.
The numbers paint a picture of sustained dominance. B2C brands rank email as their top ROI channel, while 42% of B2B marketers report email produces better results than any other marketing channel. The 4.6 billion people using email in 2025 represents more than half the global population—a reach that social media platforms still envy.
Yet this ubiquity creates its own problem. The same consumers who prefer email also report receiving more than ten marketing messages daily, with 63% saying they only open a few of those emails and 8% opening none at all.
The gap between preference and practice reveals something marketers consistently misinterpret: choosing email as a preferred channel doesn’t mean consumers want more of it.
How marketers turned permission into presumption
When consumers say they prefer email, marketers hear “send more.” The industry response to email’s effectiveness has been volume—22% of marketers now send marketing emails two to three times daily, and brands collectively dispatch 361 billion emails every day. This approach assumes that channel preference equals infinite capacity.
The data challenges this assumption directly. Getting too many emails remains the primary reason consumers unsubscribe. Over half will unsubscribe after receiving just four or more marketing messages from the same company within 30 days.
Yet marketers continue optimizing send frequency, testing subject lines, and refining segmentation strategies—all while their messages increasingly land in spam folders or trigger immediate deletion.
The noise extends beyond frequency to relevance. Fifty-six percent of consumers unsubscribe because content is no longer relevant to them, yet brands continue treating email lists as assets to maximize rather than relationships to maintain. The industry celebrates open rates, click-through rates, and conversion metrics while consumers report frustration, lost trust, and the simple desire to be left alone.
The essential truth marketers avoid
Email’s effectiveness depends entirely on whether recipients actually wanted to receive the message.
Consumer preference for email as a channel isn’t permission to occupy their inbox—it’s a statement about which interruptions they’ll tolerate when brands earn the right to send them.
This distinction matters more now than ever. Gmail and Yahoo now enforce a maximum spam complaint rate of 0.3%, meaning just three complaints per thousand emails can trigger delivery restrictions.
More critically, 20% of consumers bypass the unsubscribe process entirely and simply mark unwanted emails as spam—a behavior that directly damages sender reputation and triggers algorithmic filtering across entire domains.
The winners in this environment aren’t the brands sending more emails or optimizing subject lines. They’re the ones who understand that “preferred channel” means consumers will check email when they choose, not that they’re waiting for brand messages to arrive.
What actually drives preference versus rejection
Consumers spend an average of eight seconds reading brand emails, yet 61% report spending at least that much time when the message earns their attention.
The difference between deletion and engagement comes down to whether brands understand the contract they’re entering when someone provides an email address.
The consumers who say marketing emails influence their purchase decisions aren’t responding to frequency or clever subject lines. They’re engaging with messages that arrive at relevant moments with content that matches their actual interests.
When brands ask consumers what frustrates them most about email marketing, the answers reveal systematic misunderstanding: 34% cite recommendations that don’t match their interests, 24% mention expired offers, and 51% report receiving content they never expected.
These aren’t technical problems requiring better segmentation algorithms. They’re relationship problems that emerge when marketers treat email addresses as distribution channels rather than invitations to specific conversations.
The brand that sends three highly relevant messages per month will consistently outperform the competitor sending three messages per day, regardless of open rate optimization.
The challenge isn’t getting messages delivered to inboxes. It’s recognizing that inbox placement means nothing if the recipient never wanted the message in the first place.
Email remains the preferred channel because consumers can control when and how they engage with it. Brands that respect this dynamic earn attention. Those that exploit channel preference discover their messages filtered, deleted, or worse—contributing to the rising tide of spam complaints that now threaten entire email marketing programs.
Preference isn’t the same as permission. And permission, once granted, doesn’t grant unlimited access.
