Best Email Marketing Tools for Creators in 2026

Quick Verdict

Last Tuesday I accidentally sent my entire 3,000-person subscriber list a test email with the subject line "test test ignore pls" and then spent three hours frantically trying to unsend it through a customer support chat that answered in Sanskrit. That’s when I realized my email tool was garbage. So I went on a manic hunt testing nine different platforms in two weeks. Here’s who survived.

Mailchimp *** (3/5) – still the default but it’s gotten bloaty and expensive
ConvertKit **** (4/5) – great for creators who actually write
Beehiiv ***** (4.5/5) – the new hotness for newsletters, actually earns it
Substack *** (3/5) – simple but you’re stuck in their walled garden
MailerLite **** (4/5) – boring and reliable, which is a compliment
Brevo (Sendinblue) *** (3.5/5) – good transactional, lousy for newsletters
Flodesk **** (4/5) – if you care more about aesthetics than deliverability

I burned $120 on a ConvertKit plan last March and sent exactly three emails. That was the month I learned that shiny automation sequences don’t write themselves. Anyway.

The worst part about testing email tools is that you have to actually send emails to test them. And every email you send is a permanent record of your stupidity. I have a subscriber named "Dave" who’s gotten six different welcome sequences from me because I kept importing my list into new tools and forgetting to exclude him. Dave, if you’re reading this, I’m sorry. Please open something.

I’ll go through the ones that didn’t make me want to throw my laptop into the Hudson.

Mailchimp

Used to be the only game in town. Now it’s like that bar that was cool in 2015 and still plays the same playlist. The free tier is fine if you’re under 500 people, but the moment you cross that line they send you a very polite but menacing invoice. I once had a client on their Premium plan paying $299/month for basically the same features as the $59 plan, but with a phone number you can call. I called it once. The hold music was a dead parrot.

Thing I hated most: Their Drag & Drop builder is like playing Jenga blindfolded. One wrong move and your entire layout shatters. And the email analytics? They count "opens" based on a pixel that most email clients block now. So you’re basically guessing.

ConvertKit

If you’re a serious creator who writes long-form content, ConvertKit gets you. It’s built for people who have actual sequences and tags and segments. I used it for six months and the tagging system alone saved me from manually sorting people into "interested in dog training" vs "just here for the freebies." But the visual automation builder is like learning a third language. I built a two-step sequence, published it, and somehow sent the same email to my entire list three times. Good times.

Thing I hated most: Their landing page builder looks like a hostage note that’s been redesigned by a committee of square fetishists.

Beehiiv

I’m biased because I’m writing this on Beehiiv’s public editor right now. Yes, you can embed blog posts and grow your audience inside their platform. The whole "write once, publish everywhere" thing actually works. The referral program is surprisingly effective – I got 200 new subscribers last month just from people sharing my link because I offered a free PDF about bad email subject lines. But the free plan limits you to 2,500 subscribers and the upgrades are sneaky.

Thing I hated most: The growth tools are great but they also feel a tiny bit spammy. You know, like "refer 5 friends to unlock this secret article" energy. I felt dirty doing it. Then I saw the dopamine hit of new subscribers and I felt less dirty.

Substack

The simplest option. You write, people subscribe, they get an email. If you want to charge money, they handle payments. That’s it. There’s no tagging, no automations, no A/B testing, no "maybe send on Tuesday instead of Wednesday." It’s a blunt instrument. Perfect if you’re a writer who just wants to write and not think about deliverability metrics. Problem is, you can’t take your subscribers with you if you leave. They’re Substack’s subscribers, not yours. And the suggested-post algorithm is creepy – it keeps recommending articles from people I explicitly unsubscribed from.

Thing I hated most: I had a piece about my dog that accidentally went viral and Substack’s algorithm started showing it to everyone, including my therapist who unsubscribed after reading about my anxiety. Thanks, algorithm.

MailerLite

The Walmart brand of email tools. Doesn’t look fancy, doesn’t feel fancy, but it works for $10/month. I’ve used it for small projects and the deliverability is surprisingly solid. Their customer support once answered my email in 11 minutes at 2am. That’s either terrifying or admirable. The drag-and-drop editor is basic but I never broke it, which is more than I can say for Mailchimp.

Thing I hated most: The templates look like they were designed in 2012 and no one’s told them yet. I spent an hour making a template that didn’t look like it was promoting a garage sale.

Brevo (formerly Sendinblue)

I tried Brevo because it’s cheap and has good transactional email. If you run a store and need order confirmations, great. For newsletters? Please. The builder is sluggish, the automation rules are confusing, and the contact management gave me a headache. I deleted my account after two days. The only reason I’m including it is that someone might need it for transactional emails and be tempted to use it for newsletters. Don’t.

Thing I hated most: The interface feels like it was translated from French by someone who learned English from bad subtitles. "Your email is sent with success. A report shall be generated." Okay, okay.

Flodesk

This is for creators who care more about aesthetics than function. The templates are gorgeous. But the deliverability is a known issue – some email clients just dump them in spam. Also no free tier, it’s $38/month from day one. I signed up for the trial, designed a beautiful welcome email, sent it, got a 12% open rate. My MailerLite emails get 45%. Hard pass for me, but if you’re a designer who needs pretty and doesn’t mind low opens, go for it.

Thing I hated most: The popup forms are beautiful but they load so slowly on mobile that visitors have already left before they appear.

I started this whole mess because I wanted a tool that didn’t make me feel like I was yelling into a void. Then I realized that every tool has a void issue because email is inherently one-way. So I asked myself: what do I actually need? I need decent deliverability, a tagging system that doesn’t require a PhD, and a price that doesn’t make me question my life choices. And maybe a way to not accidentally email my entire list "test test ignore pls."

Here’s what I actually use now. Beehiiv for my newsletter. MailerLite for my transactional stuff. And a prayer every time I hit send.
