Three Email Marketing Myths Nobody Bothers to Debunk

Key takeaways:

• The email marketing myths that get debunked endlessly (send time, inbox placement, list size) are tactical distractions, the real myths are about what email is actually for.
• Most email marketing advice is written for e-commerce businesses. If you sell services or deep knowledge, the benchmarks, metrics, and playbooks were not designed for you.
• For professional services, email reaches people who already chose to hear from you, the warmest possible audience. Treating it as an acquisition channel instead of a relationship channel is the mistake that makes it feel like it doesn’t work.

The myths everyone debunks are the wrong myths

There is a whole industry of content dedicated to debunking email marketing myths. Is Tuesday better than Thursday? Does your subject line need an emoji? Will five exclamation points trigger a spam filter?

These are real questions. They are also almost completely irrelevant if you run a professional services business.

I have been watching clients use email as part of their business development for long enough to notice a pattern. The ones who feel like email marketing doesn’t work for them are almost always following advice designed for a different type of business entirely. The benchmarks they measure themselves against, the metrics they chase, the frequency strategies they follow, all of it comes from a world where you are selling a $49 product to someone who found you through a Facebook ad.

If you sell deep knowledge, strategy, or a service that costs thousands of dollars and takes months to close, that framework is not just unhelpful. It actively produces the wrong behaviour.

Is open rate the right metric for a service business?

For e-commerce, open rate is the starting point because you need volume. A 0.3% click-through rate on 50,000 subscribers still generates 150 sales. The maths works because of scale.

For a professional services business with 300 people on your list (all of whom have worked with you, referred you, or specifically asked to hear from you) open rate tells you almost nothing useful. The number that counts is how many replies you got. How many conversations started. How many times someone forwarded it to a colleague with a note saying “this is exactly what we’re dealing with.”

Those are not trackable in most email platforms. They show up in your inbox. They are the actual signal that email is working for a service business, and most people stop sending because their open rate dropped from 42% to 38% and they concluded the channel wasn’t performing.

Does email marketing help you reach new people?

This is the framing that causes the most damage. Email marketing in the e-commerce sense is partly an acquisition channel, retargeting lapsed customers, running promotions to people who abandoned their cart. Reach is part of the model.

For service businesses, your email list is not an acquisition channel. It is the people who already decided they want to hear from you. That is your warmest possible audience. People who have worked with you, people who met you at a conference and liked what you said, people who read something you wrote and subscribed.

Sending them a promotional newsletter treats them like they need to be sold. They don’t. They need to be reminded that you exist and that you still think clearly about the things they care about. That is a completely different job, and it requires completely different content.

The moment you start writing for “subscribers” rather than for the specific people you actually want to work with, the quality drops and the replies stop.

Does sending frequency determine whether email marketing works?

The advice to send every Tuesday at 10am, or twice a week, or on a “consistent schedule above all else,” comes from a media and publishing mindset. If you are running a newsletter as a product, frequency and habit-formation matter. Readers need to know when to expect you.

For most service businesses, this creates a different problem. The pressure to fill a Tuesday slot produces content that exists to fill the slot. Weak observations. Repackaged advice. Things you would not say out loud in a client meeting because you’re not sure you actually believe them.

I send a monthly dispatch. Not weekly. Once a month, when I have something worth saying. The people who receive it are the ones I want to have conversations with, and I would rather send them one genuinely useful observation a month than eight things I wrote because I had a publishing schedule to keep.

The “consistent frequency” advice is correct for media businesses. For most professional services firms, it produces the wrong outcome.

A useful test: if you removed your logo and sent that email as a plain-text message from your personal address, would it still be worth receiving? If the answer is no (if it only makes sense as a branded newsletter from a company) it is probably not doing the relationship work you need it to do. The goal is for someone to read it and think about a problem they’re dealing with, not to click through to a service page.

At Chillybin we work with a lot of professional services firms on their website and digital presence, and email consistently comes up in those conversations. The businesses that use it well are almost never the ones with the most sophisticated automation or the best open rates. They are the ones who have something to say and say it clearly to the right people.

The email marketing industry is built almost entirely on e-commerce data. The benchmarks, the A/B testing frameworks, the open rate obsessions, they reflect a world where you are moving products at volume. If that is not your business, most of what gets written about email marketing is not wrong exactly. It just does not apply. Knowing the difference is most of the work. The three myths worth debunking are not about send time or spam filters. They are about whether you have correctly identified what email is for in your specific business context. Once that is clear, most of the tactical questions answer themselves.
