My inbox is sort of a field of goodies: You by no means know what you’re gonna get (with apologies to Forrest Gump).
Simply right now I acquired:
- A e-newsletter from Monumental Sports activities Community celebrating the profession of Nicklas Backstrom, a beloved participant from the Washington Capitals who simply departed the NHL. I’m a fan. I engaged; I clicked by way of and skim the article.
- A promotional electronic mail providing accounting providers for a company that may be a shopper of mine, from an organization I’ve by no means heard of. I dislike chilly electronic mail, particularly when it’s completely irrelevant to me. I didn’t interact.
- An electronic mail from Sephora. I perused it and wasn’t actually serious about any of the merchandise featured. However, I remembered that I wanted a brand new mascara so I clicked by way of and bought one for in-store pick-up. I engaged.
- An automatic message from SAP CloudSupport about an IT safety replace. I began receiving these years in the past out of the blue. The content material is transactional, not promotional, so there’s no unsubscribe hyperlink (it’s not required below CAN-SPAM), however they’re completely irrelevant to me. I didn’t interact.
I’ll wager your inbox is sort of a field of goodies too — as a result of just about everybody’s is. And that features your electronic mail subscribers.
How are you going to ensure that your emails are ones they interact with? Let’s focus on.

4 Forms of Emails With the Highest Engagement
There are various types of marketing emails, but these are the four with the highest engagement.
1. Welcome Emails
There’s a moment right after someone signs up for your list where they’re still curious. Still paying attention. Still wondering if they made the right decision.
That moment? It’s the honeymoon period.
And a well-timed, well-crafted welcome email (or even better, a short welcome series) doesn’t just capitalize on that moment – it can become the highest-performing message in your entire program.
Case in point: I worked with a B2C client that sells professional training courses. Their welcome email didn’t just beat the performance of their regular sends, it crushed it.

You can get the details on the case study here.
Sure, the revenue-generated-per-thousand-emails-sent (RPME) for the welcome message was thrice that of the corporate’s common handbook ship. And the conversion price? Greater than 5 instances their handbook ship common.
And this wasn’t some fluke or one-time promo. It was their automated welcome electronic mail. The quiet overachiever that runs within the background and by no means takes a break day.
So why does it work so effectively?
As a result of the welcome electronic mail hits when consideration, intent, and goodwill are at their peak. Your new subscriber is anticipating to listen to from you. They need to know what they simply signed up for. They’re open to your message … perhaps greater than they’ll ever be once more.
A powerful welcome electronic mail:
- Delivers fast worth. Not “thanks, right here’s our homepage” however one thing that makes the subscriber really feel like signing up was the proper transfer.
- Units expectations. Allow them to know what’s coming and after they’ll hear from you subsequent.
- Drives motion. Makes use of a clear format and clear, low-friction CTAs to put out the trail in your reader.
Consider it this manner: If somebody reveals up in your metaphorical porch and rings the bell, a welcome electronic mail is you opening the door and saying, “Hey, glad you’re right here. Let me present you round.”
It’s not simply well mannered. It’s highly effective.
Welcome emails aren’t non-compulsory. They’re foundational. If you happen to’re not optimizing this a part of your program, you’re leaving straightforward income and long-term relationship fairness on the desk.
2. Automated Emails Triggered by a Recipient’s Motion
If welcome emails are the honeymoon, triggered emails are the “You left your keys on the counter” textual content that brings somebody again earlier than the door absolutely closes.
These automated sends – issues like cart abandonment and browse abandonment emails – aren’t simply well mannered reminders. They’re workhorses. Silent performers. All the time-on income turbines.
And so they work as a result of they’re behavior-based. You’re not guessing what the subscriber is likely to be serious about — you know. They advised you with their actions.
Take deserted cart emails. I labored with a DTC ecommerce model the place the abandonment message was outperforming the shopper’s common promotional emails by a large margin. Open charges have been 50%+ above common. Click on-throughs? Greater than double. Conversion price? Greater than 2.0%. Income-per-email-sent? Via the roof (like “$18 in income for each electronic mail despatched” by way of the roof) – see under.

Why? As a result of timing and relevance are baked in.
These kind of triggered emails, particularly after they’re thoughtfully written, designed with intent, and despatched promptly, routinely outperform the remainder of this system.
They really feel private. They’re well timed. And so they’re straight tied to the recipient’s habits, which makes them extremely efficient.
So in case you’re not but leaning into triggered sends as a part of your electronic mail technique? That’s a niche price closing.

3. Emails That Provide Worth to Readers With out a Buy
These are my favourite emails. They’re those that present up with one thing pleasant, informative, or simply plain entertaining – and don’t instantly attempt to promote you one thing.
I name them value-first emails, and so they’re a cornerstone of any long-term nurture technique.
As an alternative of pushing a product, you’re providing a second. A recipe. A pet video. A unusual vacation tie-in that sparks curiosity or offers your reader a motive to smile.
And that’s the important thing: They open as a result of they need to. Not as a result of they’re prepared to purchase, however since you’ve skilled them to anticipate one thing worthwhile, even when there’s no CTA to obtain or demo or schedule a name.
These emails are particularly helpful when:
- You’ve gotten a protracted gross sales cycle.
- The prospect isn’t fairly able to convert.
- You’re attempting to construct belief (or re-earn it).
- You need to hold deliverability wholesome with out burning your listing.
I’ve used value-first emails to assist purchasers reverse engagement slumps, scale back unsubscribes, and hold their model welcome within the inbox for months (typically years) between main campaigns.
One of the best ones supply one thing of standalone worth – like a enjoyable truth, a instrument, or a video – whereas weaving in simply sufficient model presence to maintain you high of thoughts.
No exhausting promote. No desperation. Only a quiet reminder that we’re nonetheless right here, and nonetheless helpful.

4. Emails that Adhere to Design Greatest Practices
E-mail is a visible medium. Even those that really feel like plain textual content.
So it is smart that how your electronic mail appears – the way it’s structured, how straightforward it’s to scan, how effectively the design helps the content material – can have a big influence on engagement.
And but, too usually, design choices are made based mostly on inside opinions or model aesthetics alone. Not on what really drives efficiency.
Right here’s what I’ve discovered in 20+ years of optimizing electronic mail campaigns: The emails that get probably the most clicks and the very best engagement general are those that adhere to design finest practices.
Not overdesigned. Not fancy for the sake of being fancy. Simply clear, clear layouts that make it straightforward for the reader to soak up your message and act on it.
A couple of key finest practices that persistently drive outcomes:
- Respect the attention path. There’s a pure manner we scan content material: high to backside, left to proper. The best electronic mail designs information the attention by way of the message logically: brand, headline, subhead, picture (if in case you have one), CTA. If one thing interrupts that circulate, engagement drops.
- Use hierarchy to sign significance. Headlines ought to seem like headlines. Buttons ought to stand out from the remainder of the textual content. Hyperlinks ought to be straightforward to seek out and simple to click on, even on a cell gadget. Don’t make your reader work to determine what issues.
- Embrace whitespace. It’s not wasted house, it’s respiratory room. Cramming each pixel with content material makes your message tougher to learn (and fewer prone to convert). See the instance under.

If you happen to’re undecided how your present designs stack up, I broke down some extra real-life examples on this article. You’ll see before-and-after examples that spotlight how just some easy design tweaks can flip an underperforming electronic mail into one which delivers.
As a result of on the finish of the day, good electronic mail design doesn’t simply look good, it performs.
4 Forms of Emails With the Lowest Engagement
On this part, I’ll focus on the 4 varieties of emails with the bottom engagement charges.
1. Irrelevant Automated Emails
Let’s clear one thing up.
Sure, three of the 4 emails in our “highest engagement” class have been automated. But that doesn’t mean any automated email is automatically effective.
Automation doesn’t guarantee relevance. It just guarantees that the email will be sent.
The most successful automated emails, like welcome messages, abandoned cart reminders, and triggered follow-ups, are all responses to something the recipient did. Someone signs up for your list. Adds an item to their cart. Requests a download or fills out a form.
There’s intent. There’s context. There’s a clear next step.
But when automation is used without regard for relevance? That’s when things fall apart.
Maybe it’s a birthday message sent to someone who never gave you their birthdate. A win-back email to someone who just made a purchase last week. A “We miss you!” nudge to a subscriber who never actually engaged with your emails in the first place.
Not only do these emails not perform, they can actively damage the relationship. Best case, they’re ignored. Worst case, they drive unsubscribes or spam complaints.
The lesson here is simple: Automation is a tool. Relevance is the strategy.
If your automated email doesn’t match where the subscriber is in that moment – what they’re thinking, doing, or expecting – it won’t engage. It won’t convert. And it won’t build trust.
Automation should feel personal. Contextual. Useful.
If it doesn’t, it’s just noise.
2. Emails That Are Over-the-Top Promotional
Let’s talk about the “promote, promote, promote” approach to email.
Yes, email can (and should) drive sales. It’s a high-ROI channel. It moves the needle. I’m not here to deny that.
But if every email you send is just a coupon, discount, or “last chance!” promo … you‘re training your list to ignore you until you’re giving something away. And that’s a tough habit to break.
Email isn’t just a transactional tool. It’s a relationship channel.
Think long-term. You’re not just looking for a one-time purchase — you’re building familiarity, trust, and relevance. That means mixing in value: useful tips, insider info, even a little brand personality. The kind of content that makes your readers glad they opened your message even if they don’t click (this time).
The truth is, consistently helpful content earns attention. And attention is the gateway to action.
So yes, promote. But don’t make every email a pitch. Otherwise, the only engagement you’ll get is unsubscribes.
3. Deceptive Emails
When someone signs up to receive email from you, it’s the start of a relationship. And deception has no place in a healthy relationship. For instance:
- That friendly from address stating that the email is from a beloved brand, when it’s actually from an unknown ecommerce company that is a reseller.
- The not-quite-true subject line (You won a Ferrari!) that resolves to a pitch about entering a contest to win a car.
- That “free” offer in your body copy, which neglects to mention that you have to provide a credit card to take advantage of it.
You might get an increase in your open and/or click-through rates the first time you do this, but it’s unlikely they’ll take the action you actually want them to take once they realize they’ve been deceived.
And it’s unlikely they’ll open future emails from you, ending the relationship.
4. Emails That Recipients Haven’t Explicitly Opted In to Receive
If your email recipients are in the United States, an opt-in is not required under CAN-SPAM. Regardless, you should ALWAYS get an explicit opt-in before sending email to someone.
Here’s why.
Being a consultant based in the United States, I’ve worked with organizations whose lists are opt-in, not-opt-in, and a mix. Here are the data points to consider.

Bottom-Line Performance
Opt-in lists just perform better. Period. Here’s a client case study, one of a few that I’ve done over the years, that proves it.

Yes, both lists got the exact same email. Yes, we sent the emails at the same time.
The only difference was how the email addresses were acquired. The subscribers on the opt-in list had explicitly asked to receive email from this not-for-profit. The email addresses on the not-opt-in lists had been acquired without the knowledge of those on the list.
Read the full case study.
Spam Complaints
If the particular person receiving your electronic mail doesn’t understand how you bought their electronic mail tackle, you’re placing your self at an elevated danger of spam complaints and deliverability points.
The non-profit featured within the case research above was minimize off by their electronic mail service supplier. They have been not allowed to ship, as a result of the spam complaints they have been receiving on their sends have been too excessive. They have been so excessive that the IP they have been on, which they shared with a few of the ESP’s different purchasers, was liable to being blocklisted.
How excessive is just too excessive? Listed below are the thresholds as outlined by Google’s Email Sender Guidelines:

Years in the past I consulted for a writer. Their total listing was not-opt-in; along with scraping names off of the web (which is an aggravated violation below the U.S. CAN-SPAM Act) that they had a company-wide mandate that each worker present them 25 new electronic mail addresses a month.
After I acquired there they have been trying to incorporate finest practices to enhance efficiency. They have been additionally having critical deliverability issues. There was no manner I might assist them with the previous with out fixing the latter.
They have been sending from their very own servers and so they had their very own inside deliverability workforce, as a result of the respected advertising and marketing platforms and deliverability distributors wouldn’t work with organizations whose lists have been producing this degree of spam complaints.
It was a foul state of affairs. The one factor that may repair it, not in a single day however finally, was going opt-in. However that was a non-negotiable for them. They felt like the chance, and the price of addressing the results of taking the chance, was price it. I didn’t agree. I didn’t work with them for much longer, however we parted amicably.
Discovering the Proper Forms of Emails for Your Advertising and marketing Technique
When electronic mail advertising and marketing was in its infancy, folks would ask me whether or not they need to ship promotional messages or newsletters. I’d say “sure,” as a result of, like a field of goodies, selection can also be an excellent factor in electronic mail advertising and marketing.
The important thing to success is getting the right combination in your model – and for every of your recipients.
Listed below are the non-negotiables:
- Permission-based, opt-in messages. Don’t send emails to people who haven’t explicitly said they want to receive it
- Well-designed emails. They should be easy to skim with high readability.
- A benefit-oriented welcome message to begin the connection off on the proper foot.
- A daily newsletter that gives worth with no buy, to place your model as one which understands your viewers’s wants.
- Related automated emails triggered by key recipient actions like cart abandonment, browse reminders, and so on.
- Promotional emails that embrace social proof, like buyer testimonials, benefit-oriented content material, and a powerful CTA.
Getting Began
Does that appear like rather a lot? Don’t be overwhelmed. Nice electronic mail advertising and marketing packages aren’t constructed in a single day. Begin with one electronic mail. Then one other. Then one other. And earlier than you realize it you’ll be an electronic mail advertising and marketing skilled.
