Marketing and Sales are not two departments trying to tolerate each other

I started in sales long before I worked in marketing. Not corporate sales, either. I was on shop floors selling clothes and trainers, learning how to read customers, ask better questions and understand when someone genuinely wanted help and when they wanted me to leave them alone.

Years later, I found myself leading marketing teams, building strategies, managing pipelines and sitting in meetings where people discussed concepts like lead qualification, conversion rates, attribution and sales enablement. The language had become considerably more sophisticated, but something always bothered me: companies had managed to turn marketing and sales into two completely separate worlds.

Marketing generated the leads. Sales closed the deals. Somewhere between the two, everyone got frustrated with everyone else.

Having worked on both sides, I’ve never really understood why we accept that as normal.

Inside a business, we create departments because we need ownership and specialist skills. That makes sense.

Customers don't experience those departments.

They see a LinkedIn post, hear about you from someone, Google your company, visit your website, attend an event, download something, receive an email or speak to a salesperson. Maybe they disappear for three months. Then someone mentions your name again and they come back.

To them, that is one relationship with one company.

Inside the business, however, that same journey might involve several teams, systems and handovers. Every handover creates an opportunity for information to disappear.

Marketing knows what attracted the person but may never learn why they didn't buy. Sales knows what happened during the conversation but may have no idea what the person saw before they arrived. Customer Success eventually discovers what customers actually value, but those insights don't always make their way back to either team.

That isn't a marketing problem or a sales problem. It's a business problem.

One of the most dangerous metrics in marketing is a number with no context.

“We generated 300 leads” sounds great.

But what happened to them?

If almost none became genuine opportunities, I want to know why. Were we reaching the wrong people? Was the message misleading? Did the offer attract curiosity rather than buying intent? Were leads contacted quickly enough? Did anyone contact them at all?

Marketing can't improve properly if its visibility stops at the point of conversion.

This is especially important in B2B, where buying journeys can be long and messy. A campaign might introduce someone to your business months before they are ready to speak to sales. Equally, a campaign that generates fewer leads might produce significantly better opportunities.

If Marketing is optimising only for the number at the top of the funnel, it can end up getting very good at generating something the business doesn't actually need.

The reverse is just as important.

Salespeople spend their days hearing what the market actually thinks.

They hear the objections. They know which competitors appear in conversations. They know what prospects misunderstand about the product, what questions appear repeatedly and which problems make someone suddenly pay attention.

That information is gold for Marketing.

If ten prospects ask the same question during sales calls, perhaps the website should answer it. If one objection appears constantly, maybe Marketing should address it before the first conversation. If customers consistently use completely different language from the company, perhaps the messaging needs another look.

Some of the best content ideas I've ever seen don't come from a content calendar. They come from listening to sales conversations.

But that only works if someone creates a way for that information to travel back.

Then the deal closes and another strange thing happens: many organisations treat that as the end of the revenue journey.

It isn't.

Customer Success has access to an entirely different set of information. They discover whether the promise made during marketing and sales matches the experience of becoming a customer. They know what customers struggle with, what they value, why they stay, why they leave and what else they need.

That information should influence positioning, content, sales conversations, product decisions and future growth.

If your best customers consistently value something you barely mention in your marketing, that's interesting.

If customers leave because they misunderstood what they were buying, that's interesting too.

Revenue doesn't stop when the contract is signed.

Whenever people talk about sales and marketing alignment, the solution somehow seems to involve putting another recurring meeting in everyone's calendar.

Sometimes that's useful. Often it isn't.

Real alignment is much more practical.

Do we agree on what a good opportunity looks like? Does everyone understand what happens when a lead arrives? Can Marketing see whether the opportunities it generates become revenue? Can Sales easily tell Marketing what it is hearing from the market? Are we looking at compatible information? Does Customer Success feed what it learns back into the rest of the business?

Most importantly: are we making decisions based on the same commercial objective?

You don't need Marketing and Sales to become one department. They require different skills and have different responsibilities.

But they do need to behave as parts of the same business.

I don't think Marketing exists to make things look nice or collect impressions. I also don't think its job is simply to deliver a bucket of leads to Sales and walk away.

Marketing creates and captures demand. Sales turns opportunities into business. Customer Success turns that business into value, retention and, when appropriate, expansion.

The interesting part is what happens between those functions.

Because sometimes each individual department is performing reasonably well and the business still isn't growing the way it should.

That's usually when I start looking at the gaps.

The bottleneck might not belong to Marketing. It might not belong to Sales. It might be sitting quietly between them.
