Customer.io had the best suite of features and - most importantly for us - was willing to sign a BAA with us so we could maintain HIPAA compliance. Mailchimp was fine but we felt Customer.io had a cleaner interface and was easier for general marketers who aren't dedicated email …

Chose MailerLite
Selected MailerLite for the features + price. They blow the competition out of the water on price... and back it up with the best customer service.

Moosend specifically is overpriced for very few features, and zero support.

I've researched over a dozen and used a few different email marketing services (I have several websites using email marketing) and have yet to find an email marketing tool offering automation workflows in the free version of the product. Others almost force you to purchase a …

Customer.io
Talking from the perspective of a marketer at a SaaS with average. 50K email subscribers, Customer IO has been an excellent tool for us. Our requirements include sending users newsletters, marketing emails, and transactional emails, running lead-nurturing campaigns, and more. For a comprehensive use case like ours, CustomerIO is great. While it also has a learning curve, when you have such requirements, it’s worth it. I don’t think CustomerIO is the best fit if you have basic requirements like only weekly newsletter emails.

I didn't have much luck when testing other similar tools and since we tested with free plan, we couldn't commit to something else if we couldn't get basic stuff fixed. That's when we switched to MailerLite, and their support was great and super helpful all the way (during our free plan, especially). Plus, they're super budget-friendly for startups, so I highly recommend.

UI presented by this application is not only unique but also important to implement for further creation. Hence a proven and tested application for tracing the developments at all places to check the capability of the developmental process. It’s a powerful email marketing tool and helps to maintain the client’s relationship with full support.

Pros
Customer.io
  • Managing users, attributes and events. You are easily able to modify any user, based on their ID, and add or remove attributes, assign events to them. That makes it very easy to segment later and to assign them to several campaigns based on behavior. Just a warning: this integration isn't so easy (at least it wasn't for us).
  • Creating workflows of campaigns is very easy. You can quickly create behavioral campaigns based on attributes, segments and add elements to the workflow. You can send an email, then wait, then send another, then exit the campaign if they converted, etc. The workflow is easy to configure and very powerful for automation.
  • We don't use many email templates (we make them in MJML) but it's very easy to add senders, to change templates and in general to test designs.
  • Deliverability works very well, at least for us. It sends emails pretty fast and without issues.
  • Exporting is very quick and easy. Importing wasn't a feature until recently, but it works well too.
  • Seeing activity it's also useful. In general, logs are awesome (be it of a customer, of activity on the site, email sends, etc.).
  • We don't use environments, but it might be very useful for a bigger company.

  • Offers a user-friendly interface, making it simple to create beautiful forms, group subscribers, and automate emails.
  • Includes email automation workflows in their free plan - the only provider I know of that doesn't charge you after one month or hit you with "transaction fees".
  • Excellent video tutorial library so you can learn email marketing as a beginner without feeling overwhelmed.

Cons
Customer.io
  • Price is quite expensive for Premium or once you get into high volumes of contacts.
  • Depending on how you'll use it, it may require some help from developers to set up.
  • Despite the support being great, you have to email them, there's not chat feature.

Mailerlite
  • EVERYONE should be allowed to at least use the AI bot chat feature. This doesn't take a person and is such basic customer service that it should be offered at all levels.
  • It would be nice if MailerLite worked better with AddEvent icons
  • When emailing support it took days to get a response (after an agent escalated the issue). Some concerns are more urgent and email support shouldn't mean bad support.

  • If you have more than 1000 subscribers you will be required to upgrade to the Pro plan.
  • Free plan users have limited customer support.

Mailerlite is awesome and it does everything I need and then some. They're always innovating and adding new features, and their team is flippin' amazing. Can't see myself ever switching. They may not have everything, but looking at how well their team works, they'll get there for sure and I'm willing to wait.

Usability
Customer.io
Super intuitive and easy interface to start off with. There are not a lot of guides and the documentation is helpful but not super extensive, but even if you're a little technical, you can easily figure most of the things out by yourself. Everything is super easy to start with and the platform does not overwhelm you with a lot of options, or data.

I find it very easy to use, intuitive with a clean interface and drag and drop functionality where that adds value. It's quite configurable for our brand and the template and duplication options are very useful as we reuse a lot of content.

My experience with their support team has always been great. Very quick to respond, have an online chat, and are very helpful. They helped me resolve any issues I've had every time in a professional and knowledgeable manner. We've now switched to another tool, and I can't even compare the service level we get there to customer.io

Whenever I contact Support, either via email or through online chat, I always get a speedy response that gives me the answer I need. The AI Agent on the online chat is excellent and has helped me so much on numerous occasions.

Customer.io was really the first pure, full-featured drip email program on the market and as far as I know, it's still the simplest and best overall for that specific function. SendGrid has also added drip campaign features, but I would seriously evaluate Customer.io against any other drip email provider because they really have all the key elements you need to make it work.

MailerLite has similar features to the tools mentioned above. The main advantage is that it is very complete in its free version. This is ideal for those who are starting out and want to try a complete email marketing platform.

Moosend is known as more of an industry standard than BuzzStream (which is a more budget tool), and it shows. BuzzStream has clearly cut corners in areas of usability and general UI, where Moosend, on the other hand, seems to have done it right from the beginning. Moosend is so much less clunky than the other tools we evaluated.

Return on Investment
Customer.io
  • Positive impact on the sales side. I'm not sure about the specific ROI (you have to include the designer and the time it takes to set up) but you certainly get back the investment in a few months, once you are able to scale your email marketing.
  • Customer experience is way better by having more segmented, contextual and accurate messages sent to them.
  • Integration is costly and it will take several days or weeks to be fully achieved. Expect to invest some money on this.

Mailerlite
  • Gives us the ability to track the popularity of content in our email as well as who has read the content.
  • The customizable layout gives us the opportunity to be creative and have our culture shine through our company communication.
  • The ability to see who has un-subscribed helps our HR department to see who isn't receiving important company information so we can ask them to re-subscribe.
  • Helps our company to be more transparent and communicate more effectively.

  • Moosend is quite affordable (500,000 emails for $500), so it's easy to see an ROI. It only takes a few recipients converting to make a campaign worth the spend.
