AI is reshaping how agencies and marketing teams work. Smaller, technology-enabled teams are doing more, and email has quietly become the most effective channel for several brands. It lets them educate and promote at once while building long-term relationships. At Breaker, our TruSend™ technology is built around that shift. It turns email from a broadcast tool into a precision engagement engine, so brands can get more from the spend they already have without adding budget or complexity.

Here is how I see the biggest changes playing out.

Rising acquisition costs are forcing better measurement

When acquisition costs go up, experimentation gets more expensive, and that tends to make organisations, especially smaller ones, fearful and impatient. The upside is a sharper focus on efficiency. Teams are moving from cost per lead to cost per qualified lead.

The math is simple. Divide your cost per lead by the percentage of leads that match your ideal customer profile (ICP). A $10 lead with a 20% ICP match rate is really a $50 lead. Metrics like this sit closer to the truth, and vendor platforms rarely report them. Tracking them is where the efficiency gains come from.

Personalisation means understanding intent

Adding someone’s first name to a subject line was never personalisation. Real personalisation is understanding intent, meaning messaging based on what a person has actually done with your brand. If someone clicked your demo link and didn’t book, they should get a phone call, not another generic email.

Authenticity comes from expertise and relevance. If you provide great products and services, understanding intent connects the two. AI can help you get there, but it doesn’t replace customer empathy.

AI has collapsed the cost of output, not the cost of knowing what to say

A team of three can now produce what used to take ten or more. But output was never the biggest bottleneck in B2B marketing. The hard parts are knowing who to reach, what to say and when to say it.

AI is also an underrated tool for targeting. Connect your marketing data to it and ask the right questions, and you can reach findings that once took days or weeks. This is where great agencies and marketers still matter. If AI is a 2X force multiplier for the average marketer, it’s closer to 10X for a true expert. Impact rises in both cases, but skill still creates the leverage.

What “precision engagement” means in practice

Conventional email marketing starts with “who wants my emails?” and then segments by “who engaged?” That’s useful, but it’s far less precise than starting with “who matches the profile of people who buy from us?”

TruSend™ is what we call email intelligence. It evaluates a wide range of variables to understand ICP, intent, interests and probabilities, so distribution starts with your ideal customers. On the other side, advanced algorithms filter out machine-generated engagement, so the numbers you see reflect real people.

Connected data turns signals into revenue

Most companies already have the data they need. It’s just scattered. Marketing sees opens and clicks, sales sees calls and contracts, and that gap is where deals quietly die.

If a subscriber clicks “book a demo” but never books, and that signal stays in the email platform, it’s a missed opportunity. If it lands in your CRM and a salesperson calls that day, that’s revenue on the books. When your subscriber list and pipeline talk to each other, you can answer the questions that shape a budget: how long subscribers take to buy, how many issues they read first, and which ones look like your best customers. As with skill and AI, connected data plus AI is a force multiplier.

Where email goes next

I think email splits into two camps. One uses AI to send more: more content, more sequences, more noise, a race to the bottom. The other uses AI to decide who should get a message, what they need to hear, and whether they need to hear from you at all.

I also expect more B2B companies to operate like niche media brands. Buyers increasingly research without a salesperson in the room, and they buy from vendors they already know. A great weekly newsletter is how you get on the shortlist before the budget is approved.
