A client of mine sells building products that are installed through a network of contractors. These contractors are never at a desk. They’re on job sites, in trucks, walking through warehouses. Email open rates were dismal. Not because the content was bad, but because the channel didn’t match how these buyers actually work.
So the team tested something simple. They offered opted-in contractors the option to receive updates, order confirmations, and product alerts via SMS instead of email. No app download. No portal login. Just a text they could read in 10 seconds and reply to on their terms.
Engagement didn’t just improve. It changed the relationship. Contractors started replying with questions, reorder requests, and job-site photos. A one-way marketing channel became a two-way conversation, because the company finally met buyers where they actually spend their time.
The question most teams are really asking
Most B2B marketing teams, when they talk about “mobile strategy,” mean one of three things: a responsive website, mobile-friendly emails, or maybe a dedicated app.
Those are fine. But they answer the wrong question.
The question is not “is our content mobile-optimized?” The question is: are we reaching buyers in the channel they actually use during their workday?
For buyers who sit at desks and check email throughout the day, mobile-friendly email is probably enough. But for buyers who are on job sites, driving between appointments, managing warehouse floors, or running field operations… email is not where they live. It is where messages go to sit unread.
Think about it. If your buyer checks their phone between jobs but never opens a laptop until 9 p.m., it does not matter how clean your responsive design is. You are still trying to reach them in a channel they do not use during the hours when they make decisions.
What actually changed
Back in 2013, I reviewed how several Fortune 500 B2B companies were handling mobile. Most did not have a mobile site at all. The ones that did (Caterpillar, Grainger, a few others) stood out because they designed for how their buyers actually worked. Caterpillar built its mobile experience around field needs: finding dealers, checking specs, starting quotes from a job site. Grainger separated mobile site for prospects and app for existing customers, with quick reorder features for repeat buyers.
The principle was right. Design for the buyer’s context, not for your internal workflow.
What has changed is where that principle points. In 2013, “mobile” meant making your website usable on a smaller screen. In 2026, it means asking whether your buyers even use a browser during their workday. For a growing number of B2B buyers, especially in field-based industries, the answer is no.
SMS. Text-based order confirmations. Messaging apps. Push notifications for reorders. These are not trendy additions to a marketing stack. For non-desk buyers, they are the primary communication channel.
The system gap nobody talks about
Here is what makes this a system problem, not just a channel preference.
When my building products client started getting SMS replies from contractors, something interesting happened. Contractors replied with questions. They sent reorder requests. They texted photos from job sites asking about product fit.
But the system was not ready for it. Those replies were not captured in the CRM. They did not create activities or update contact records. The buyer experienced a responsive, personal interaction. The system recorded nothing.
The fix was routing those SMS replies through Salesforce Omni Channel. That turned each contractor text into a tracked activity in the CRM, visible to the right person, actionable.
This is the part most teams miss. You can open a mobile channel and get great engagement. But if your GTM system cannot capture what happens in that channel, you are creating demand you cannot track, route, or follow up on.
When a contractor texts a reorder request and it sits in someone’s phone instead of entering the order system, that is not a mobile win. That is a new leak in a new place.
The real work is not just choosing the right channel. It is connecting that channel to your lead management, routing, and follow-up system so the engagement actually goes somewhere.
Where to start
Start with one question: how do your buyers actually communicate during their workday?
Not how you wish they communicated. Not how your CRM assumes they engage. How they actually work.
If the answer involves trucks, job sites, warehouses, field offices, or anything that keeps them away from a desk and a browser… then your “mobile strategy” is not about design. It is about channel.
And if you open a new channel without connecting it to your system (routing, follow-up, tracking), you will get engagement you cannot convert. Which is just a more modern version of the same old problem.
That building products client figured this out. They did not just add SMS. They routed replies through Salesforce Omni Channel so a contractor’s text became a tracked activity in the CRM, not a message sitting in someone’s phone. The channel matched the buyer. And the system matched the channel.
That is what mobile actually means in B2B.
No hype. No noise. Clarity your team can actually use.
