Why the 98% Number Holds Up
Across the industry, SMS open rates are consistently reported in the 95–98% range, with the large majority of messages read within minutes of delivery. The reason is simple: a text message arrives in the same place a person receives messages from family, friends, and coworkers. There is no separate marketing folder for it to be filed into, and no algorithm deciding whether it deserves to be seen.
Email open rates, by contrast, average around 20% across industries — and that figure is generous. It counts an “open” when a tracking pixel loads, which means a message previewed for half a second in a crowded inbox can register the same as one that was actually read. The gap between SMS and email is not a difference in degree. It is a difference in how the two channels work.
Why Email Open Rates Are Softer Than They Look
Email open tracking depends on a tiny invisible image loading when the message is viewed. Apple Mail Privacy Protection, launched in 2021 and now widely adopted, pre-fetches that image for many users whether or not they ever open the message — inflating reported opens. Other privacy tools and corporate mail servers block the pixel entirely, hiding real opens. The result is an open-rate number that is simultaneously too high for some senders and too low for others, and unreliable for everyone.
Layer on top of that the structural filtering email faces: spam folders, the Gmail Promotions tab, sender-reputation thresholds, and the simple fact that the average professional receives well over a hundred emails a day. Even a well-crafted message is competing for attention against that entire pile. SMS faces none of those filters.
It Is About the Channel, Not the Copy
Marketers often try to close the open-rate gap with better subject lines, send-time optimization, and list hygiene. Those tactics help at the margins, but they cannot overcome the structural disadvantage. The inbox an email lands in is shared with newsletters, receipts, notifications, and other promotions. The inbox a text lands in is reserved for people the recipient has chosen to hear from.
That is why TextingOnly treats SMS as the channel for moments that matter now — appointment confirmations, time-sensitive offers, qualification follow-ups, and re-engagement — and treats email as a complement for longer-form content. The point is not that email is obsolete. The point is that being reliably seen, immediately, is a property only SMS provides at scale.
What 98% Changes About Campaign Design
When you can assume a message will be read within minutes, you design differently. Time-sensitive offers can carry real urgency because the audience will actually see them in time. Qualification and follow-up conversations can happen in near real time. And a single send reaches almost the entire list, rather than the fraction email reaches, which changes the math on every campaign.
It also raises the bar on relevance and consent. A channel with 98% open rates is a channel where every message is genuinely seen — so frequency and value matter. TextingOnly’s structured opt-in, OTTO qualification, and per-contact data exist precisely so that the messages you send into that high-attention channel are wanted and relevant, not noise.
Speed: The Second Half of the Story
Reach is only half the advantage. Response speed is the other half. SMS replies, when they come, arrive in minutes; email replies — when a recipient replies at all — typically arrive in hours or days. For any workflow where timing affects the outcome, such as connecting with a high-intent lead before a competitor does, that latency difference is decisive.
This is why SMS pairs so naturally with qualification and callback workflows. A contact who replies within minutes can be routed, qualified, and prepared for a call while their intent is still fresh — something email’s slower rhythm cannot support.
Use Both Channels for What They Do Best
None of this means abandoning email. Email remains strong for long-form storytelling, detailed nurture sequences, and content that benefits from rich layout. The mistake is using email for the moments that require certainty of being seen, and assuming a 20% open rate is just the cost of doing business.
The highest-performing programs use both deliberately: email to build and educate over time, SMS to reach and convert when timing matters. TextingOnly makes the SMS half measurable and owned — every contact captured with consent, every interaction attributed, every list reusable.
Reach the Audience Email Misses
If your most important messages are landing in a channel where four out of five recipients never see them, the channel — not the copy — is the constraint. SMS removes that constraint, and TextingOnly makes the channel structured, compliant, and attributable.

98% vs 20% is not a marketing claim — it is a structural property of the two channels. Design your most time-sensitive messages around the one that actually gets seen.
