Why Batch Emails and Brochures Aren't a Strategy Anymore

Somewhere in the last decade, "we send a monthly email" became shorthand for "we have a customer communication strategy." It doesn't mean that anymore, if it ever really did.

This isn't a criticism of institutions that are doing it. Batch emails and printed brochures made sense in a world where those were the best tools available. They were better than nothing. In some cases, they were quite good. But the world customers live in now is different, and the expectations that come with it are different, and an institution that's still running the same playbook is falling further behind every quarter.

Here's why.

Batch Communication Was Built for a Pre-Personalization World

The logic of the batch email is: we have a segment of customers, we have something to say, we say it to all of them at once. It's efficient. It's scalable. And it assumes that what you have to say is relevant to enough of them that the effort is worth it.

That assumption used to hold. When the alternative was saying nothing, a broadly-targeted email about a new savings rate or a CD promotion was better than silence. It got the message in front of people. Some percentage engaged.

But customers now live in an environment where nearly every digital interaction they have is personalized. Their streaming service knows what they like. Their retail apps know what they've been looking at. The notifications they get from their phone are timed to when they're likely to be paying attention. That's the baseline.

Against that baseline, a batch email that addresses them as "valued customer" and promotes a product they already have, or don't need, doesn't just underperform. It actively signals that the institution doesn't really know them.

The Open Rate Is Not the Metric That Matters

There's a trap in email marketing analytics. Institutions see a 25% open rate and feel good about it. People are opening the emails. The communication is working.

But open rate measures attention, not action. It measures whether someone clicked the email, not whether anyone's financial behavior changed. It doesn't tell you whether any customer who opened that email actually had a CD mature, or actually needed a loan, or was actually at a decision point when the email arrived.

The question that matters is: did this communication reach the right customer at the right time with something that was actually relevant to where they are in their financial life right now?

A batch email almost by definition can't answer yes to that question, because the content was built for a segment, not a moment. The timing was built around a send schedule, not a customer event. The message was built to avoid irrelevance for most people, which means it's usually not deeply relevant to anyone.

Brochures Have the Same Problem, Amplified

Printed brochures are the extreme version of the same failure mode: a message built weeks in advance, designed to be broadly applicable, delivered to someone at a moment you cannot predict or control.

They have their place, a lobby display about current rates, a product overview at account opening. But as outreach instruments? As a way to deepen customer relationships or drive revenue at a meaningful scale? They don't work, and the economics of printing and mailing them have made them increasingly hard to justify.

More importantly, they ask the customer to do everything. The customer has to notice the brochure. Read it. Find it relevant. Decide to act. Initiate the next step. Every friction point in that chain is a dropout opportunity.

Modern customer communication should work in the opposite direction: the institution identifies the moment, initiates the contact, makes the message specific, and makes the next step frictionless. That's the inversion batch communication cannot perform.

What's Actually Required Now

Effective customer outreach in 2026 has a few non-negotiable characteristics:

It's triggered by customer events, not calendar dates. A loan payoff, a CD maturity, a new direct deposit, a large balance change… these are the signals that indicate a customer is at a moment worth reaching. Calendar-based send schedules will always miss most of those moments.

It's specific to the individual. Not just "Dear [First Name]" personalization, actual relevance. The message references something real about the customer’s account and their current situation. That's what makes it feel like service rather than marketing.

It reaches the customer where they are. Not everyone prefers email. Text messages have dramatically higher open and response rates for time-sensitive communications. Voice outreach is right for certain customers and certain situations. A channel strategy that defaults to batch email because it's familiar is leaving engagement on the table.

It makes responding easy. A customer who gets a relevant text about their CD renewal shouldn't have to call in, navigate a menu, and wait on hold. They should be able to respond to the text. Ask a question. Get an answer. Decide. Done.

It's compliant. This is where many institutions get stuck. TCPA regulations and opt-in requirements create real friction around text and phone outreach. But compliance is a problem to solve, not a reason to stay with batch email. The institutions that figure out how to run compliant, personalized outreach at scale will have a significant structural advantage over those that don't.

The Stakes Are Higher Than They Appear

When the marketing team sends a batch email and gets a 22% open rate, the cost of that approach isn't visible on any report. What's not visible: the 78% who didn't open it, including the ones who were at a financial crossroads when it arrived and didn't realize the institution had something to offer them. The customers who renewed a CD elsewhere because no one reached out when the timing was right. The loans that went to a fintech because no one made a relevant offer when the customer needed one.

Batch emails and brochures aren't causing obvious harm. They're just quietly failing to do what customer communication is actually supposed to do: reach people at the moments that shape their financial decisions, with something relevant enough that they choose to stay, borrow, save, and grow through their community institution.

That's not a high bar. It's just a different one than the one most institutions are currently clearing.

The tools to clear it exist. The question is whether "we have a monthly email" continues to feel like enough of an answer. Learn more about the Outreach tool that calls, texts, emails and sends personalized micro-sites for less than the cost of a direct mail brochure.
