What Users Say

Reviews from Trustpilot, linked to the source

Trustpilot

“Issue with subscribers not getting confirmation emails. Support on chat was pushed to a "senior" support agent who suggested a few things and then ghosted me not responding to any questions.”

Trustpilot

“This has been the worst email and webinar platform I have ever used. Their customer service is unresponsive and ineffective. I created my webinar so people could register, but the day of my event, they restricted my account without warning.”

When to Consider Sequenzy Instead

SaaS-Focused

Neither is built for SaaS. Sequenzy offers SaaS email with Stripe-triggered automation at $49/month.

Overview

MailUp and Kit (formerly ConvertKit) serve entirely different audiences. For our take on each, see our MailUp comparison and Kit comparison.

Kit for Creators

Kit is purpose-built for creators. Paid newsletter subscriptions, digital product sales, a creator network for cross-promotion, and a sponsor marketplace. MailUp has none of these. If you're building an audience and monetizing content, Kit has the ecosystem.

MailUp for Business Volume

MailUp's strength is unlimited contacts with the BEE editor and SMS. For businesses sending campaigns to large lists with professional design needs, MailUp is the practical choice at half the price of Kit's paid plans.

The Sequenzy Alternative

For SaaS founders who don't need creator features or unlimited contacts, Sequenzy combines transactional email and marketing campaigns with Stripe integration at $49/month.

Email Design Philosophy Comparison

MailUp and Kit have fundamentally opposite design philosophies. MailUp's BEE editor encourages rich, visually complex emails with images, buttons, and multi-column layouts. Kit intentionally keeps emails simple and text-focused, believing that plain-looking emails feel more personal and drive higher engagement in newsletter contexts.

Both approaches have merit. Data consistently shows that simple, text-like emails often outperform heavily designed ones for newsletter content. However, branded businesses with e-commerce or B2B audiences often need polished visual emails. Your choice should depend on your content type and audience expectations.

Monetization and Revenue Models

Kit's monetization features are unique in the email space. Paid newsletter subscriptions, digital product sales, the creator network for cross-promotion, and the sponsor marketplace create a complete revenue ecosystem for creators. No other email platform offers this combination. MailUp has no monetization features whatsoever.

If you are building a media business or personal brand, Kit's ecosystem can directly generate revenue. If you are running a traditional business that sends marketing emails to customers, these features are irrelevant. For SaaS companies specifically, Sequenzy's Stripe integration provides subscription-aware email that neither Kit nor MailUp offers.

Audience Growth and List Building

Both platforms offer tools for growing your email list, but they approach it differently. Kit provides landing pages, signup forms, and the creator network which can expose your newsletter to new audiences through cross-promotion with other creators. MailUp offers landing pages with 42 templates and basic signup forms.

Kit's creator network is a genuine differentiator for list growth. When other creators recommend your newsletter, you get qualified subscribers who are already engaged in your niche. MailUp has no equivalent. However, for businesses that grow their list through paid advertising or website traffic, MailUp's tools are sufficient and more cost-effective.

Use-case matchups

Need Better fit Why
Flat-rate campaigns, polished email design, SMS, and client previews MailUp MailUp is cited for unlimited contacts, BEE editor, SMS, previews, A/B testing, and lower cost at 10k.
Creator newsletters, paid subscriptions, products, and creator network growth Kit Kit is cited for creator monetization, paid newsletters, digital products, sponsor marketplace, and creator network.
Businesses outside the creator economy MailUp Kit's own tradeoffs note it is not suited for every business outside creator-led publishing.
SaaS lifecycle and transactional email Sequenzy Sequenzy is listed at $49/month with transactional plus marketing and Stripe integration.

Best Fit by Audience Model

Best email marketing tool for non-creator business campaigns

MailUp fits businesses that need polished email design, SMS, previews, A/B testing, and flat-rate sending outside creator-led publishing. It is strongest when campaign production quality matters more than creator audience monetization.

Best email platform for creators and paid newsletters

Kit is the better fit when paid subscriptions, digital products, sponsor marketplace, creator network growth, and audience monetization drive the workflow. It works better when the creator wants to sell directly to an owned audience.

Best email platform for SaaS lifecycle and transactionals

Sequenzy fits when subscription lifecycle, transactional email, and Stripe integration matter more than creator monetization or broad campaign design. It is more relevant when product events and billing state should drive automated messages.

Pricing reality

MailUp is listed at about $47/month for Starter with unlimited contacts and emails. Kit is listed at $100/month for Creator at 10k subscribers. Sequenzy is listed at $49/month for 60k emails (unlimited subscribers), with transactional plus marketing email and Stripe integration.

MailUp is less than half the cited Kit price at 10k subscribers. Kit can still justify the premium when paid newsletters, creator network growth, and digital products are central to the business.

Review signals

MailUp reviews cited here highlight large-list value, professional email design, and the BEE editor. The cautions are a functional but uninspiring interface and weaker creator-specific features.

Kit reviews cited here highlight paid subscriptions, creator network growth, automations, and tagging. The cautions are higher paid-plan pricing and a narrower fit outside creator businesses.

Migration checklist

  • Export subscribers, tags, forms, landing pages, products, paid subscriptions, sequences, sponsor settings, SMS settings, templates, and suppressions.
  • If moving to Kit, rebuild paid products, lead magnets, creator-network settings, tags, and visual automations.
  • If moving to MailUp, decide how paid newsletters, product delivery, and creator discovery will be replaced.
  • Reconfigure SPF, DKIM, DMARC, sender identities, tracking domains, signup forms, and unsubscribe handling.
  • Test paid flows, forms, automations, templates, and deliverability before switching acquisition traffic.

Decision checklist

  • Choose MailUp if this is general business email with a large list and design needs.
  • Choose Kit if creator monetization and audience growth tools are the core business.
  • Avoid MailUp if paid newsletter operations are central.
  • Avoid Kit if the business just needs lower-cost campaigns.
  • Choose Sequenzy if the creator business has become SaaS and email should follow Stripe events.

Founder, LandingBoost

It’s the first tool where I’m actually willing to keep working on email without it turning into one giant scary blast. Favorite part is still what I said, being able to split stuff. Drafts vs campaigns vs a single-person send. I can park a lot of “don’t send this yet” work with labels and not feel like it’s one click away from going to everyone. Sequences later. Consent / lists first. I’m slow on purpose.

We used Sequenzy to replace a generic onboarding flow with coordinated lifecycle journeys covering signup, connecting Google Search Console, discovering SEO opportunities, upgrading, and paid-customer retention. Event triggers, conditional branches, personalization, and enrollment cancellation gave us precise control over who receives each message - and when someone should exit a journey. We backfilled eligible users into the appropriate journeys. The initial emails went out without bounces, complaints, suppressions, or unexpected recipients. Future users now enter the relevant journeys automatically based on their activity in CrawlRaven.

Codex basically one-shotted the migration for syncing our audience from SendGrid to Sequenzy. Sequenzy is fully observable, so agents can just set everything up. The net impact is saving $45/mo, plus 2 hours of my time every time I need to repurpose a newsletter. That's 8 hours a month. My consulting rate is $550/hr, so every hour automated is super valuable.

Solo founder, Moxie Docs

Lifecycle email was the kind of thing I knew I would need eventually, but have never had to build it out myself and had no idea where to start. In literal hours I had a fully working (but basic) flow for onboarding new users, detecting churn, and re-engaging people who have trials lapsing to hopefully convert. Sequenzy let me offload the entire “keep users engaged and recover the ones who are slipping” workflow to something that just runs. Every hour I'd have spent building and babysitting lifecycle emails went into shipping the actual product instead.

It helped me grow to $100 MRR, get #1 on Uneed, make more sales, get acquired. I literally love Sequenzy, it's so simple, I love the dashboard. I also saw the integrations and was shocked. 3 sales today, all thanks to Sequenzy. Honestly, thanks.

Loving the Sequenzy app so far due to the affordability and large subscriber limits. Planning on this becoming my main email app. Campaign + flows setup with the help of their AI took less than 30 minutes.

I've used 2 other email marketing tools. They were supposedly "market leaders". Both were clunky, unnecessarily expensive and horrible support. When I tried Sequenzy I thought there'd be trade-offs compared to the others. But there weren't, it had everything I needed, there was no bloat, emails delivered extremely fast, and the founders shipped anything I asked in a day. The best part is that Sequenzy is AI native, I rarely do stuff in the dashboard, just use my AI to create campaigns, sequences and segment customers which saves me a ton of time. Never been happier with an email marketing tool.

$600 revenue in 30d from email automations. Very happy I migrated to Sequenzy. Before I was making zero from email automations.

Sequenzy's most powerful feature is probably those campaigns. It seems useless at first but they are one of the most important things to send to your users. I get to talk to my users 1:1 and help them set it up for their use case. The owner is really active on X, really nice and helpful. He's the type of person to go out of his way to help you, so you get really good support!

After using Loops and Resend, I was looking for an email infrastructure service that had MCP support, Affonso and Dodo Payments integrations, and was affordable. Came across Sequenzy, and the support from Nic has been unbelievable. Migration was done in 24 hours without any issues, and I can run all of my products from a single account.

Jim

Jim

Founder

I run a SaaS, and found Nic on X where I kept seeing posts about his email marketing tool, Sequenzy. I decided to try it for email marketing. Literally on the first day, I used it to send a marketing campaign and I got 5 sales. What I like most is the ai assistant because it actually writes emails that feel real instead of the usual ai slop chatgpt returns, so they do not end up in spam. It also has a 2.5k free email limit which is way better than most tools that only give you around 1k. The best part though is that it handles everything for me, tags, subscribers, sequences and all of it. Without it i would probably be managing a database and a bunch of cron jobs just to make email automation work. Sequenzy just makes my life a lot easier. it can also be set up with 2-3 clicks! Give it a try!!

I love everything about Sequenzy and also the kind of support I get from Nic. It's already the best choice for campaigns & Sequences. Specially the integrations with payment providers, auth providers & analytics etc.. is really spot on. Best in terms of features & pricing in the email segment 100% recommend it for SaaS emails :)

The setup was fast and simple. It synced customer, product, and order data quickly. Generating automated flows was simple, and it improved my monthly bottom line by about 7%.
