The biggest email marketing trends for 2026

We’ve witnessed significant changes in email marketing over the last two years. AI-powered responses and machine learning-fueled filtering, the explosion of newsletters, and much more that we’ll get into soon. But it’s also clear that email marketing isn’t going anywhere. Revenue generated from email marketing is expected to continue to grow, with current estimates saying it’ll surpass $15 billion in 2026 (That’s more than double from just five years ago!).

With that huge revenue pie growing every day, email marketing could be a lucrative part of your marketing strategy over the next 12 months. But since it’s also changing so rapidly, it’s worth paying attention to what’s on the horizon.

Here are the email marketing trends we’re expecting to see in 2026.

1. There will be a greater awareness of email marketing laws

To designate this as a trend might seem odd, but there’s renewed awareness of what is okay for email marketing with AI inbox assistants—which we’ll talk more about soon—and some recent news-worthy blunders.

Celebrity-owned suitcase brand Beis sent out a Black Friday email with an egregious subject line that alerted the recipient to ongoing fraud. If you clicked the link, you learned that the fraud was actually non-existent and the sale was extended.

Copywriter Shiri Friedman has a great breakdown of how this email breaks the law and why it’s also a bad campaign. Fraud is at best annoying and at worst catastrophic. No one who clicks to learn more is in a good mood to make a purchase.

The good news is that you’re probably following the guidelines, but it’s always good to refresh your memory and review the specifics of the CAN-SPAM Act. Especially when consumers are becoming more and more aware. (And if you’d like some ideas for effective and safe email subject lines, you’ll find a bunch here.)

2. Everything in email gets personalized…

A few years ago, McKinsey & Co. found that recipients not only respond to personalization in email but also expect this from brands. 71% of consumers expect personalization, and 76% get frustrated when they don’t see it. And this was before AI tools made personalizing your email structure and your messaging to your email recipients even easier.

Many email marketing platforms—including ActiveCampaign, Mailchimp, and more—offer AI-powered tools to help build segments or set up automated personalization, whether it’s a one-off email about the last product page viewed or a newsletter version for event attendees. If you’re not already leveraging these features, it’s time to start in 2026.

But while you’re getting that set up and testing it out, don’t sleep on the basic personalizations, like first name or location. These simple, effective tweaks can help you with light personalizations. The key is to keep going—which we’ll get into next.

My name jumps out when I’m scanning my inbox, even if I know it’s automated.

3. … even the email creative

Chase Mohseni, CEO of Creative OS, predicts that when it comes to personalization, 2026 will be “the year retention marketing finally catches up to paid.”

“We’ve had segment-level targeting forever, but now we’re getting segment-level creative,” Chase explained. “Same product, same offer, completely different story depending on whether you’re talking to a first-time buyer vs. a lapsed subscriber vs. your VIPs. Tools like Clay are making this actually executable without a 10-person ops team.”

In a promotional email like this, personalized creative could mean that the shirt colors or sizes shown change depending on the subscriber’s purchase history.

“The brands that figure out how to deliver relevant creative to the inbox are going to make everyone else’s emails look like the grocery store circulars I threw out when I checked the mail this morning,” Chase added.

4. Humanizing content becomes table stakes

AI is amazing for making complicated tasks quick to execute and, in lots of cases, possible for small businesses with tight budgets and slim teams. But it’s bad for building trust between brands and consumers, especially when it comes to using generative AI to create marketing materials.

Now, we’re all getting used to reading content and wondering whether or not this was written by a person or generated by AI (N.B., I’m typing this out with my real human hands). Even this consideration puts distance between the recipient and your brand personality. That’s why we’ll see more brands humanizing their content in 2026. Think less “relatable grammar errors for engagement” and more “peek behind the unfiltered scenes” charm.

Take the newsletter from Homebody, a brick-and-mortar lifestyle store in Concord, NH, that’s a go-to for gifts.

In each monthly edition of Homebody Happenings, there are new product round-ups, details for upcoming events, and first-person anecdotes or descriptions.

For example, the owner will share her favorite flavor from the local tea company that the store now stocks, recommendations for apple-picking spots around town, books she’s read about being a small-business owner, or cookbooks with must-try recipes.

Adding these light human touches lets your readers know there’s a person behind your brand—and this will go a long way in 2026. To get you started, we’ve curated a list of newsletter ideas and examples.

5. Marketers will contend with inbox filters

In 2026, marketers will have to contend with new email inbox algorithms. The way email providers decide what reaches a user’s inbox is rapidly evolving from simple tried-and-true spam rules to complex, AI-driven relevance and engagement models.

Since 2024, Google has required bulk senders to have SPF, DKIM, and DMARC set up for their domains. Yahoo has similar requirements to ensure deliverability. Keeping an eye on these technical authentication methods is a good place to start.

Major mailbox providers like Gmail, Outlook, and Yahoo are increasingly using machine learning to assess not just this technical compliance but also how recipients interact with messages. This includes opens, replies, and forwards. And it also includes how quickly a user opens an email or whether they move it to their primary tab. Emails that don’t generate consistent engagement can see deliverability drop sharply or be routed to spam or relegated to secondary tabs, like Gmail’s Promotions, reducing visibility and ROI.

Starting 2026 with a renewed focus on deliverability and engagement can go a long way toward ensuring your contacts actually receive your emails. And email strategies that consistently underperform might be worth rethinking or scrapping entirely. Which leads us to the next email marketing trend.

6. Cold email will become less attractive

While personalization will go deeper and make email marketing more meaningful, Allen Finn, director of marketing at Skio, doesn’t think it’ll save cold emails in 2026.

“Everyone’s running the same playbook now. Pull some intent data, scrape a LinkedIn post, drop it into a template that opens with ‘Hey {first_name}, saw {company_name} just {recent_news_event}…’ and call it personalization,” he said. “It’s not personalization. It’s a mail merge with better inputs. And because the tooling made this so easy, every B2B inbox is now flooded with emails that feel personalized but obviously aren’t. Recipients can smell it.”

So, some of those tactics to make emails more relevant may work for mass sends, but in cold emails directed at individual prospects, they may actually have a negative impact.

“I got one last week,” Allen continued, “that opened with ‘Would reaching 20-30% more prospects needing subscription management software for Shopify brands that your competitors aren’t contacting be valuable to you?’ That’s not personalization. That’s a robot doing a keyword search on my LinkedIn.”

The bar for personalization in these individualized outreach emails is significantly higher, and more of us are aware of the plug-and-play style of personalization. This makes large-scale cold emails less effective.

Finn’s prediction for 2026 is a change in strategy: “The best outbound teams will abandon cold email entirely and shift to signal-driven LinkedIn outreach or pick up the phone and provide REAL VALUE. At Skio, our BDRs sign up for subscriptions at brands that use competitors, document the process from the customer perspective, then reach out to key decision makers with a free game. Is this more work than playing plaintext template madlibs? Of course. But effort that can’t be faked is what actually converts.”

7. Omnichannel marketing strategies will need better integration

Another way to engage authentically with your audience is to consider all of the interactions a person has with your brand in an omnichannel marketing strategy. This integrated approach ensures that all touchpoints—email, social media, SMS, website, and in-store interactions—work together to create a seamless customer experience rather than disconnected messages.

In 2026, it’ll be more important than ever to integrate email with other marketing channels.

I don’t know about you, but I find the disconnected messages annoying and intrusive. Whenever I get a push notification, a text message, and an email in quick succession with completely different tones and offers, it’s a reminder that I have too many open forms of communication, and I unsubscribe from one or all of them.

This kind of abrasive messaging and opting out is what you want to avoid with an integrated marketing strategy, especially in 2026, as the bar for personalization and a smooth experience gets higher.

8. Influencers are coming for email marketing

The influencer marketing industry is worth over $30 billion. It’s been growing steadily, and for good reason. Influencer marketing is effective.

In 2026, Social Snowball VP of marketing Clint Ross expects to see influencers in our inboxes.

“Influencer whitelisting is coming to email,” he said. “Creator-fronted ads are already crushing it on IG and LinkedIn, but email is still stuck in brand voice purgatory. And newsletter sponsorships? Oversaturated, generic, and the ROI has cratered. This is the next evolution.”

Clint explained how this will work.

“Picture this: Marques Brownlee, tech reviewer extraordinaire with 20 million YouTube subs, is one of your affiliates,” he said. “Instead of buying a blurb in someone else’s newsletter, you send an email from him to your list. His name in the sender field. His voice. His product picks are based on what he actually uses.”

Clint said this is the same playbook that’s working with thought leaders and UGC content, it’s just applied to your email marketing strategy. “And this isn’t just an open rate play. You’re layering creator trust directly into the channel with the highest purchase intent. Someone who already opted in, already bought, now getting a recommendation from a creator they follow? That’s a conversion engine.

There’s even a low-tech version, Clint said. “Spin up an alias for your creator on your domain and start testing. No new tools required. I’m surprised more brands aren’t already doing this.”

Whether you’re working with influencers already or not, leveraging influencers for email campaigns is something to consider for this year. And remember, influencer marketing works well for small businesses, too.

9. Depth takes over for volume

No one wants more email, exactly. But lots of people do want updates from brands about new offerings, notifications about significant sales on products they’re interested in, even periodic updates about events or happenings. Square even found that 60% of consumers prefer to get updates from brands they frequent or follow via email.

But with marketers leveling up their email marketing game, what you send needs to be impactful. “Email marketing in 2026 is about depth over volume,” according to brand and marketing consultant Denise Reid.

Meaningful messaging will deliver better results than a tidal wave of fluff in 2026.

The key will be sending the same or fewer emails that are better at engaging subscribers. “I’m leaning into AI not just to send smarter messages, but to analyze what’s actually working so we can predict subscriber behavior and replicate the content they care about most,” she said. “To outsmart spam filters and land in real inboxes, I’m asking subscribers to save our email address in their contacts while keeping our list healthy through preference forms and welcome sequences,” Reid explains.

“Shifting to fewer, more intentional emails builds trust, keeps subscribers engaged, and leads to conversions because they’re receiving tailored content they actually care about.”

Stay on top of email marketing trends in 2026

There’s a throughline of focusing on quality that runs through this year’s email marketing trends. While sending engaging and relevant messages has always been important, it’ll be even more so this year as some brands opt to “flood the field” with large quantities of impersonal AI-generated content.

Tell real stories. Offer peaks behind the curtain. And most of all, know who your customers are so you can deliver on a promise of not clogging their inbox with generic outreach (which are also great tips for social media in 2026).

Keep these trends in mind, and you’ll keep those email clicks and conversions rolling throughout the year.
