Push and SMS traffic, explained

Push and SMS are two of the highest-volume, most direct channels in performance marketing, and two of the most misunderstood. Both deliver a message straight to a device the user already checks constantly. Both can produce enormous reach at low cost. And both come with rules that, if ignored, turn a promising channel into a liability. Here is what advertisers should understand before they run either.

What push traffic actually is

Push traffic comes from users who have, at some point, allowed a website or app to send them notifications. Those subscriber lists are built across thousands of sites and can reach into the millions. When a campaign runs, a short message with a headline, an icon and a link appears on the user's screen, and a fraction of them tap through. Because the subscriber base is so large and the cost per send is so low, push can generate volume quickly, which makes it a natural fit for testing offers and finding scale.

The tradeoff is intent. A push subscriber was not searching for your product; they simply agreed to receive alerts. Like native, push traffic is colder than search, so it rewards strong hooks and a landing experience built to warm the visitor rather than demand an instant purchase. Volume is easy; quality is where the skill lives.

What SMS traffic adds

SMS reaches the user in the single most personal inbox they own: their text messages. Open rates for SMS are famously high because almost everyone reads their texts. That intimacy is exactly why SMS is also the most tightly regulated channel of the two. Used well, it drives immediate, measurable response. Used carelessly, it generates complaints and legal exposure fast.

The compliance basics

Different regions have different laws, but the principles are consistent. The audience must have agreed to receive messages. The message must not misrepresent who is sending it or what the offer is. Recipients must be able to stop receiving messages easily, and that request must be honored. For SMS in particular, rules around consent and content are strict and enforced, so serious operators keep their sending lists clean and their claims accurate. This protects your brand as much as it protects the recipient.

Running push and SMS on performance

Both channels lend themselves well to performance pricing. Because sends are cheap and volume is high, media teams can afford to be paid on results, structuring on CPA or CPS so you only pay when a real action occurs. That alignment matters even more here than elsewhere, because the temptation to chase raw volume is strong; tying payment to outcomes keeps the focus on quality traffic rather than sheer send count.

The practical workflow mirrors native. Start with a controlled test, measure which segments and creatives actually convert, then scale the winners. The channels can move fast, which is a gift when something works and a warning when it does not, so tight tracking is essential from the first send.

When to use them

Push and SMS shine when you need volume and speed, when your offer has broad appeal, and when your funnel can convert a colder, impulse-driven visitor. They are less suited to narrow, high-consideration products that need lengthy evaluation. For the right offer, though, few channels can match how quickly they reach a large, reachable audience.
