beehiiv
Best marketing-focused newsletter platform
Best marketing-focused newsletter platformBeehiiv is one of the best modern-day marketing newsletter platforms for businesses and creators.

What is beehiiv?
What is beehiiv?beehiiv is one of the best newsletter platforms out there if you're trying to build, grow, and actually make money from your audienceIt's built around marketing features and ROI in a way most traditional email tools just aren't.
Unlike tools like Mailchimp, Klaviyo, or ActiveCampaign, beehiiv feels much more purpose-built for newsletters, especially if referrals, sponsorships, paid subscriptions, and audience growth are part of the plan.
A lot of that comes back to why it was created in the first place. beehiiv was co-founded by former Morning Brew team members, including Tyler Denk, who was Morning Brew's second employee. Morning Brew for context was a dedicated newsletter business that exited for $75M.
And Tyler? He worked across product, engineering, and growth. He literally redefined what a newsletter could be, using viral growth tactics like a powerful referral system, which led to Morning Brew becoming one of the largest newsletter exists ever. They got very good at growing newsletters.
So this is why beehiiv actually feels different. Most email marketing software has bolted on newsletter growth features because customers asked for them, but beehiiv was built from the ground up by a team that actually understood the needs of a newsletter business at the deepest level.
They knew referrals, analytics, monetization, and audience growth needed to be core to the product from day one. And to them, it was super clear that there was a massive gap in the market as none of the existing platforms actually gave them what they needed. So Tyler and the team ultimately left Morning Brew to build the newsletter platform they wished they had.

Kit
creators looking to send emails to their audience and communities
creators looking to send emails to their audience and communitiesKit (formerly ConvertKit) was built primarily for small businesses and creators, and does marketing emails and basic email flows super well.
While it's more basic than many other options, it gets the job done especially if you're a smaller team with less complex needs.

What is Kit?
What is Kit?Kit (formerly ConvertKit) is one of the oldest email marketing providers on the market (in-fact, I used them for 7 years in my prior consultancy business back in 2015), and while that is normally a huge red flag to us, they have actually done a good job at staying relevant over the years.
They've focused heavily on being the best solution for creators and small businesses, and have managed to capture a lot of the creator economy especially.
And this shows itself when looking at what tools Kit integrates with. Unsurprisingly, all the growth and marketing tools in our Creator stack.

Loops
Best for startups who need deep product email functionality
Best for startups who need deep product email functionalityLoops sends marketing and transactional emails with a super simple, modern interface that avoids the clutter and complexity of tools like Mailchimp, Hubspot, or ConvertKit, making it easy to create campaigns, sequences, and segment audiences without getting lost in extra features.
If you want an email tool that just works, stays out of your way, and lets you automate or trigger emails from your CRM with minimal hassle, this is the one to pick, especially if you're tired of bloated pricing and confusing workflows.

What is Loops?
What is Loops?We've used just about every single marketing and transactional email sending tool on the market, and we believe that Loops is the most simple and modern solution, poised to take much of the market share in time.
You're probably exploring tools like Mailchimp, Hubspot (Marketing Hub), ConvertKit, and even Postmark, and you're probably banging your head against the wall because you're overwhelmed with options and not quite sure of the difference.
And that's totally fair! Believe us, we've used them all and more. Dive into Mailchimp and you'll be introduced to what feels like 20 different areas to accomplish basic things—they used to be the most user-friendly solution on the market, but with growth has come complexity and segmented products (like why are they trying to get me to create a website...?)—sending email shouldn't be so complicated.
I mean come on, you have contacts (an audience), and then one-off bulk emails (campaigns) you want to send to your contacts, and sequences (Loops) which are re-usable emails (e.g. like a newsletter or customer onboarding sequence):
Screenshot of Loops
The main differentiation point of Loops is that it is just super simple and straightforward to use. You can easily segment down your audience (contacts) by defining in the campaign or sequence whatever filtering criteria you'd like specific to the actual one-off email or sequence you are sending out—super straightforward:
Example of how to build a segment within an email sequence
What we like to say is the best email tool is one you rarely need to open up. Wait, what? Yeah create your email sequences once, and then use their flexible API to easily pass these contacts from your CRM to Loops.
While they advertise themselves as "better email for SaaS", we've been able to use them for our evergreen newsletter, which has nothing to do with integration into our products, it really just means that they have a robust API, allowing you to easily trigger one-off or sequences of emails (Loops) to go out at various points in the process.
These other email sending tools like ConvertKit, MailChimp, and Hubspot have just added so many additional "features" to try and extract more money (with the blink of an eye you'll be spending $20k/yr with Hubspot to unlock all of their marketing automation features). Loops on the other hand just has simple pricing and "gets out of the way", with a clean email editor, powerful API, and a great user-experience.
P.S. We use and love Postmark for sending transactional via our Communicate app, but that's only because it's more of a product, in most cases, companies shouldn't really be looking at an email sending tool like Postmark for marketing automation. Not to mention, Loops has actually just added transactional (one-to-one) email support, which should be able to take care of most transactional emails (like password reset emails, etc.)
Klaviyo
Best eCommerce email marketing platform
Best eCommerce email marketing platformWe spoke to a few friends running e-commerce stores across different niches, and every single one was using Klaviyo for their email flows. At this point, it's basically become part of the default e-commerce tech stack.

What is Klavyio?
What is Klavyio?Klaviyo is one of the best email marketing tools for e-commerce stores, especially if you want to build out things like different sales sequences, upsells, or abandoned cart flows.
Klaviyo gives you templates that are based on best practices from across the e-commerce space, which is why they tend to perform well. When speaking to friends in the e-commerce space, they all said they use Klavyio, it’s pretty much become the default tool e-commerce stores rely on.
While Klaviyo started as only email marketing flows, they now call themselves a B2C CRM where your customer data, messaging, and automation all live in one place. That’s what allows you to personalize flows based on real behavior (e.g. you can email someone if they added a product to their cart and didn't check out, or send them an email sequence if they haven't re-purchased in the past 60 days. Klaviyo also seems to be better than Shopify for A/B testing these flows.).

Customer.io
For onboarding communication flows
For onboarding communication flowsCustomer.io handles segmented onboarding funnels and lets you manage communication flows with customers visually, plus it connects well with tools like Slack for updates and event pushes. If you need a full-featured email marketing tool, this is not the right choice.

What is Customer.io?
What is Customer.io?Customer.io is great for building segmented onboarding funnels within your product (e.g. a series of emails and push notifications based on the onboarding flow).
It allows you to manage all of your communication flows with the customer in a visual way.
We've been seeing more and more companies switch over to this due to their flexibility of native integrations.
You can also do things like push app sign-ups and in-app events to a shared channel in Slack, or even use it to automatically push out updates to shared Slack Connect channels.
Mailchimp
Legacy email marketing tool
Legacy email marketing toolMailchimp buries you in confusing options and makes even basic email sending feel complicated, while pushing flashy templates that actually hurt engagement. If you want straightforward, effective marketing emails that feel human and aren't a mess to set up, skip Mailchimp entirely, look for something simpler.

What is Mailchimp?
What is Mailchimp?You're probably exploring tools like Mailchimp, Hubspot (Marketing Hub), Kit, Loops, and even Postmark, and you're probably banging your head against the wall because you're overwhelmed with options and not quite sure of the actual differences.
You're probable checking "does it integrate with my CRM?" and the most confusing bit of it all is that what you think integrating with your CRM and what the marketing sites list as integrating are two totally separate things.
Mailchimp is the 800lb gorilla in the space—has been around the longest, has the most "integrations" out of the box, but as they've grabbed more and more of the market, they've had to expand their product offering to generate more revenue. Even expanding to offering websites, stores, and appointment booking (only to get worse with their recent acquisition by Intuit—how do you become a $100bn email sending company? You don't, you expand to everything but the kitchen sink):
The sheer number of options and products available is overwhelming
So dive into Mailchimp and you'll be introduced to what feels like 20 different areas to accomplish basic things (even just on the sending email front)—sending email shouldn't be so complicated.
They also focus heavily on "beautiful email templates that match your brand", well the open-rates and click-through of highly templated/branded emails have fallen off a cliff in recent years. Would you believe that with so much automated emails, people actually prefer receiving emails that feel like they were sent by a human? Big shocker, right? 😅
We highly recommend checking out a more simple tool like Loops to build out and manage your marketing emails (it's what we use for our newsletter).

What is Postmark?
What is Postmark?Postmark is a transactional email service, used for password reset emails for example. They've always been great, but they got acquired by ActiveCampaign, and have been going downhill ever since.
