Cross-channel campaigns need a production home, not just a sequence
If you run marketing for a B2B company, you have probably already been thinking about SMS and RCS. Your buyers carry their phones everywhere, they read a text within minutes, and meeting people where they actually are is just good marketing. The instinct to add these channels is the right one, and plenty of tools will happily help you act on it. Your marketing automation platform can fire an email, wait a day, send a text if the email goes unopened, and drop an RCS message when things go quiet. That part works, and it works well.
Which is why the interesting question isn't whether you can reach someone across three channels. You can. The question that tends to get skipped is where those three messages get built in the first place, and whether they came from the same place at all.
Cross-channel sending is solved; cross-channel production isn't
None of what follows is a knock on sequencing. Deciding who gets which message, on which channel, in what order, and triggered by what behavior is genuinely hard, and the tools that do it have gotten good. That is the whole promise of meeting someone where they are: the email for the person who lives in their inbox, the text for the person who never opens one, the RCS card for the moment a richer message earns its place. The logic that routes all of that is real, and it is dependable enough to build on.
Think, though, about how a cross-channel message usually comes together today. The email gets designed in your email tool, reviewed by brand, and polished over a few rounds. The SMS gets written somewhere else by whoever owns texting, maybe in a spreadsheet, maybe against a deadline. The RCS card gets assembled by whichever person piloted RCS in the first place. Each one is fine on its own. Put them in the same customer journey and the seams start to show: the consent language doesn't quite match, the offer wording drifted somewhere between tools, and the card is still carrying last quarter's logo. Nothing in the sequencing layer catches this, because lining messages up in the right order was never the same job as making sure they belong together.
That is the gap worth naming, and it is nobody's fault in particular. You can coordinate the timing of three channels while building them in three separate places, to three separate standards. The sequence looks cross-channel. The production behind it isn't yet.
One production home for email, SMS, and RCS
This is where having a single home for campaign production changes the math. When your email and your landing pages already get built in one place, with shared content, shared brand controls, and one approval pass, adding SMS and RCS to that same place lets them inherit the same discipline without anyone reinventing it. The offer gets written once and reused. The consent language is defined once. The brand check the email passes is the same check the text and the card pass, because all three came off the same bench.
Picture one launch offer moving through that home. The headline, the value proposition, the consent line, and the brand assets get defined a single time. The email, the SMS, and the RCS card each draw from that shared set, so the words a buyer reads on their phone are the words your brand actually approved rather than a paraphrase someone retyped into a texting console under deadline. When legal updates the consent language, it updates in one place and every channel reflects it. When brand swaps the logo, the card is not the thing that quietly gets missed. The campaign runs on one source of truth instead of three, and the review that protects your email is the same review protecting everything beside it. That is what keeps not just the messages in sync, but the people building them.
The strain shows up in the teams as much as the campaigns. Enterprise marketing-ops teams already spend real energy keeping people aligned across tools, and it is telling that 61% of them name silos as their number one barrier, according to the 2025 State of the Marketing Ops Professional report. Standing up a new channel in its own separate tool is a reliable way to add one more silo. Bringing it into the home your email and landing pages already live in does the opposite: same criteria, same review, same source of truth, one more surface. What you get is a cohesive campaign rather than a set of parallel tactics quietly running their own strategies.
Why relevance now drives cross-channel campaign performance
There is a second reason this matters more this year than it did a couple of years ago, and it has to do with what happens to your message after it sends. The surfaces that carry email and notifications have stopped being passive pipes. They summarize, rank, and increasingly rewrite what lands on the screen. Apple Intelligence began summarizing Mail in late 2024, Gmail's Gemini summaries followed, and on-device models now condense what shows up before a person reads a word of your actual copy. As the writer Jacques Corby-Tuech puts it in his piece on push notifications, "volume kills permission, and relevance is the only reliable lever you control." He is writing about push, but email is a fair preview of where every intermediated channel is heading.
You can watch this happen in your own inbox. When a model writes a two-line summary of an email and the recipient reads that instead of opening the message, the value you delivered is real, but the open never fires and the interaction moves into a layer you cannot instrument. What the model rewarded was whichever message was clear and relevant enough to summarize well. That is relevance doing its work upstream of every metric you are used to watching.
Follow that into the cross-channel question and it gets clarifying. If a model is going to compress or reclassify your message the moment it arrives, then sequencing generic content perfectly across three channels doesn't buy you much. What earns a place on the screen is relevance: content genuinely worth surfacing, on brand, and shipped while the moment is still live. Relevance is something you build, not something you schedule. You cannot sequence your way to a message worth reading. You have to produce it, across every channel the campaign touches, from the same brief and against the same standard.
The channels themselves are getting easier to treat as first-class, which is part of why this is worth planning for now. Apple made RCS manageable on the iPhone in iOS 18, and that one change quietly turned a consumer curiosity into something a B2B team can reasonably build around. The rails are arriving whether or not our production practices are ready for them.
It is worth being straight about the state of play here. In B2B, cross-channel is still taking shape, and a lot of the eye-catching read-rate numbers for SMS and RCS come from B2C retail. That doesn't make them wrong, it makes them instructive. Consumer teams have been living in these channels for years, and there is a lot to learn from how they treat them. The through-line for B2B isn't chasing a retail open rate. It is the quieter advantage of producing relevant, on-brand content across channels as your buyers spread their attention over more of them.
Where Knak fits
Knak has spent its life on exactly this layer for email and landing pages: one place where distributed teams design, build with shared brand controls, and move through a single approval before the finished asset syncs to the platform that sends it. The Figma-to-MAP workflow was always less about any single email and more about keeping a whole team producing to one standard. That is the part that tends to break the moment a second and third channel show up without a shared home to hold them. Extending that same production model from email to SMS and RCS isn't a new idea for Knak so much as the next room in a house that was already built for it. Whether or not Knak is the tool you choose, the argument holds: give your channels a shared home and the campaign stays coherent.
The market handed us a way to line up messages across channels a while ago, and that job is genuinely done. The one still open is building those messages together, to one standard, fast enough to stay relevant while the moment lasts. If you are weighing what a cross-channel setup should actually do before you bolt SMS or RCS onto your email program, book a demo and start with where the messages get built, not just how they get sent.
