If you’ve been told that beautiful image-heavy emails tank your open rates, that numbers in subject lines boost performance, or that you need to schedule sends on specific days at specific times, you might be working with outdated advice, according to a new report from Flodesk. A comprehensive analysis of over 14 billion emails reveals that much of what small creators have been told about email marketing is simply wrong.
We’re breaking down the real data from the Flodesk 2026 Email Marketing Trends Report so that you can stop guessing and start optimizing your designer newsletter.
The image-heavy email myth
Here’s what you’ve probably heard: emails need to follow the 80/20 rule 80% text, 20% images or they’ll tank. The Flodesk report analyzed actual performance data and found that this is mostly fiction.
The text-to-image ratio explains only 0.3% of the difference between campaigns. What matters far more? The actual content and who you’re sending it to. Two emails with identical text-to-image ratios can perform completely differently based on audience relevance and timing.
The real takeaway: design your emails in a way that’s best for your brand and your audience. Don’t force yourself into a formula that doesn’t work for how you want to communicate with makers.
Subject lines: shorter and smarter.
Subject lines matter far more than ratios, and the data is clear on what works. Keep subject lines concise. The sweet spot is 6-9 words. Subject lines with 12 or more words or 90+ characters see roughly 4-6% lower open rates.
Numbers used to seem like a safe bet, but here’s what actually works: skip plain numbers entirely. Subject lines without a number showed open rates up to 14% higher. If you must use a number, pair it with a currency symbol. Numbers with a dollar sign outperform plain numbers by up to 12%.
Timing: Tuesday and Friday for the win.
Forget trying to find the mythical perfect send time; the data is decisive: send Tuesday for clicks (up to 31% higher click rates) and Friday for opens (up to 10% higher). The best time to send is five to 8:00 a.m. Eastern Standard Time, which beats the rest of the day by up to 21% in opens.
For designers launching new patterns or announcing events, Tuesday sends will drive more clicks to your shop or registration page. Friday sends build awareness and get more eyes on your work
Segmentation changes everything: 4x opens, 3x clicks.
Here’s where dramatic improvements happen: Flodesk members who send to segmented lists see significantly better results than full list sends. How much better? Four times the opens and three times the clicks
Even better, Flodesk members who exclude unengaged subscribers see open rates about 11% higher, click rates about 30% higher, and bounce rates about 40% lower.
This means separating your audience matters. Email your engaged subscribers people who opened your last three newsletters differently than everyone else. Email people you recently purchased patterns differently than people who just joined your list. This segmentation drives real business results.
Weekly list cleaning boosts performance.
Clean your email list weekly and watch your numbers climb. Weekly cleaning boosts click rates up to 41% and cuts unsubscribers down by 31%.
Think of it this way: inbox providers look at engagement patterns from your audience. When you send to engaged subscribers, your emails land in inboxes; when you send to inactive people, your emails get flagged as spam. A clean list signals to email providers that your content matters to recipients.
Emojis are your ally when used right.
Emojis won’t hurt your open rate; in fact, they help lead with two emojis at the start of your subject line for up to an 11% open lift. Midline or bookend placement can cost you up to 31% in opens.
The winning Emoji of choice, sparkles (✨), leads the pack with over 230, 0000 uses, followed by party popper (🎉) at 126, 0000+ uses. Both are proven in-box scene stealers that build anticipation before the click.
Most “spam words” aren’t actually guilty.
You’ve probably been warned against certain phrases: “work from home,” “make money,” “limited time,” “guaranteed,” “hurry,” “don’t miss out.” “act now.” The report tested over 70 phrases blamed for triggering spam filters and found only seven actually hurt your open rates, and each one only cuts open rates by 5 to 20 points.
Most of the advice about spam words was built on data from large companies sending to massive lists, not creators like you. Use language that’s authentic to your voice; if saying limited time reflects your actual release strategy, say it.
Forms and full-page experiences convert.
Full-page email sign-up forms and social forms are the highest-performing sign-up vehicles with average sign-up rates ranging from 31% to 47%. If you’re trying to grow your newsletter using your existing website form, this is worth testing.
Workflow templates that deliver results.
Two template types consistently outperform the rest. Lead magnet delivery: getting a freebie into someone’s hands instantly sees click rates 13.5 * higher than the rest. Plain text purchase follow-ups also crush it; open rates are 3.5 times higher than other workflows.
This means if you’re giving away a free pattern or guide in exchange for an email sign-up, deliver it instantly and make it easy. If someone buys a pattern, follow up with a plain-text note, not a designed email thanking them and suggesting what to make next; this approach works.
Design emails for your audience, not the rules
The biggest takeaway from this data is this: stop following formulas that were built for Fortune 500 companies. You’re a designer building community with makers. Give yourself permission to approach email differently.
Your email list is your most direct connection to your customers. It’s the one place where platforms and algorithms can’t get between you and the people who support your work. Treat it with the care it deserves.
