Does email marketing still work — and for whom
The question usually comes from the same place: social reach is down from last year, ad costs keep climbing, results keep shrinking. Someone suggests going back to email, and the answer lands fast: "no, email's dead, everyone's on Instagram now." That answer rarely comes from data — it comes from looking at your own inbox.
Your own inbox is a bad sample. You get dozens of marketing emails a day; your average customer does not. The real question isn't "does email work" — it's "does it work for your business, with your list" — and the answer depends on both.
Why the question keeps coming up
Three things happened at once. Ad costs on Meta and Google climb year over year — the same result costs more each time. Organic reach on social platforms is set by the platform's own algorithm and can drop overnight with no input from you. And one or two emails landing in spam are enough to write off the whole channel, when the cause is usually a technical setup issue, not the channel itself.
Together, those three things produce the feeling that email is dead. Feeling and data are not the same thing.
What the data actually says
Mailchimp's latest cross-industry benchmarks put the average open rate at 35.63% and the average click rate at 2.62% (source). Those numbers swing hard by industry — some sectors run double that, some run lower — but the average itself does not support "nobody opens these."
Litmus's report on email marketing ROI puts the average return at $36 for every $1 spent, higher than any other channel they track (source). The mechanism is simple: paid ads charge per click, while a list, once built, costs close to nothing per additional send.
That figure is an average, not a guarantee. An email sent to an unsegmented list with nothing of value inside will not reproduce either number.
Who it works for, and who it doesn't
Email marketing works under one condition: a list of people who have already interacted with you. A buyer, someone who filled out a form, downloaded something, opened an account — someone who knows you and gave consent. If that list exists, the channel works, because the recipient is already interested and you're only reminding them.
Without that list — addresses bought or collected without consent — the result flips. Open rates drop, spam complaints rise, mailbox providers (Gmail, Outlook) start treating your domain as suspicious, and that can push even emails to people who did consent into the spam folder. A bad list doesn't just hurt its own send — it damages the whole channel's standing.
For businesses with repeat purchases — e-commerce, courses, a beauty salon, a real-estate agency, B2B services — email is especially strong, because the customer has already paid once and expects a next step from you. For a one-off product with no repeat contact, the upside is smaller, but not zero — it still helps move a hesitant buyer to a decision.
The one channel that doesn't answer to an algorithm
This is where the real difference sits. Your Instagram page, your ad account, your TikTok profile all live on someone else's platform, and that platform can change the rules tomorrow. Reach can drop, an account can get suspended, ad prices can climb — none of it under your control.
An email list works differently. You hold the names, the addresses, the open history yourself — in a spreadsheet or your sending tool's own database. The platform can shut down, the tool can change, and the list stays with you. It's the one audience channel you actually own; everything else is rented.
An ad account can get suspended, a page can get taken down — no platform can take your email list away from you.
Three steps to start with
If you have a list but aren't using it, or you send the occasional promo without tracking what happens next, these three are enough to begin.
1. Segment the list
Sending the same email to everyone is the most common mistake. A brand-new subscriber and a customer from three years ago shouldn't get the same message — one needs an introduction, the other a reminder. The minimum split: new subscribers, active customers, and people who've gone quiet.
2. Set up a welcome sequence
A short automatic 2–3 email series that fires the moment someone subscribes — who you are, what you offer, what the first step looks like. It consistently outperforms manual sends on open rate, because it reaches the recipient at the exact moment their interest is highest.
3. Promise one concrete outcome per email
"Here's our newsletter" doesn't get opened. "20% off until Thursday" does. Every email should carry one outcome and one clear action button — an email with two or three competing links confuses the reader into clicking none of them.
The bottom line
Email marketing isn't dead — but it isn't automatic for everyone either. With a consented list that actually knows you, and a clear outcome in every send, it's one of the cheapest, most stable channels available. Without those two things, build them first, and run campaigns second.
If you want help segmenting your list, setting up automated sequences, and measuring what each send actually does, our email marketing service starts by assessing the state of your current list.
