Chose Customer.io
We used Autopilot in the past. It worked well but the integration wasn't very good, considering they only used cookies. We have a very complex system right now to be able to track every customer, and it was expensive but worth it. Autopilot worked very well when we were …
Chose Customer.io
Customer.io is much more comprehensive and powerful. It takes some getting used to but once you understand how it works, you have a ton of control when it comes to email marketing.
Chose Customer.io
I found Customer.io much easier to navigate than any of the other email platforms out there, and the pricing is MUCH better as well.
Chose Customer.io
Customer is much more flexible and enables a greater amount of personalization.
Chose Customer.io
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 …

Customer.io
This tool is well-suited for companies looking to run email marketing campaigns or send out newsletters regularly to their users/customers. The workflow setup is especially useful for companies who want to send specific emails based on user behavior - i.e. they've not logged in recently, have bought a specific product, haven't opened any emails, etc. This could also be useful for freelancers like me since you can create different workspaces within Customer.io. I have configured it this way to handle email marketing for a few of my clients, and the software keeps everything organized and separate. This might not be the best tool for small businesses, considering the price. It may be better to start out with a cheaper email marketing tool, and then if/when necessary, scale-up with a tool like Customer.io.

With Mailchimp we are able to revive and enhance our personal connect with the customers. The easy-to-use tools allows us to personalize the email content, segregate and target important leads & send relevant messages. Also, it offers interactive analysis on the performance of a particular campaign. We can judge the effectiveness of our mailers in real time.

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.

  • Mailchimp allows you to manage your mailing list really well. You can subscribe people, unsubscribe people manage the mailing list directly into segments, and what not.
  • Mailchimp has features where you can create campaigns based on your mailing lists and send out newsletters to your subscribers based on a multitude of parameters that you can setup. Such as send email daily, weekly, monthly and they also have event based mails that you can send out.
  • Mailchimp also has a feature where you can design your emails. The look and aesthetics are very important when sending emails to your subscribers and all those needs are addressed here.

Cons
Customer.io
  • Push notifications are very rudimentary. Everything has to be done by hand unless you're sending an extremely simple message.
  • A bit too email centric.
  • Lacks an ability to schedule messages on a daily, weekly, etc. basis.

Mailchimp
  • The interface remains a cluttered, non-intuitive mess. That's true from the haphazard way features are organized to the actual email layout.
  • Analytics have never been a priority, and I don't see that changing with Intuit's new ownership. I'm very frustrated over the limited choices for reporting, even when using third-party solutions. If I needed that function, I would not use MailChimp.
  • I would love to develop a workflow screen that lets me focus on the things that I use all the time. Customizing the interface where the content actually goes into the software would help.
  • I never understood why we couldn't import a document into a MC template. At best, we're spending time copying-and-pasting from one app into MC.

We've had Mailchimp for about ten years, I want to say. I started with the company about four years ago, and I don't see us ever diverting to another source. It's easy for us to use, and we have all our clients already built into the database. I imagine we'll use them for as long as we have the company.

Our team use Mailchimp almost every week. Overall UI is simple for anyone to get started with it. The resource library around using particular features is also there, so we don't have to train our team on this product. We also used a lot of other features as well.

I have, in the 4+ years that I've used Mailchimp, never seen an issue that restricted the use of their software/tools. I don't know of a single time when they're system crashed or went down. I could be wrong, but I honestly haven't experienced any issues with outages, errors or unplanned downtime

I haven't noticed any slow speeds from Mailchimp or their tools. I think the landing pages load quickly and look nice. The email reports and editing operates smoothly and doesn't take time to load. Additionally, when I use Mailchimp in conjunction with Zapier + Hubspot I don't notice any drag between any of these tools

Website tools were easy to use and understand so a novice can easily meet or exceed their client's expectations! Loved that we were able to totally customize so that the e-mail we created conveyed our client's overall messaging consistent with their branding!

It's pretty easy to get up and running! There's a slight learning curve on a few things, but once you find where everything is located, you can import your list and send your first email. It really makes our clients feel great to see how quickly they can get that first email out.

Mailchimp is a means to an end and a way to stay within GDPR laws. We may not use it if this wasn't a requirement. Other platforms are better for design or management of contacts, but Mailchimp offers that secure storage of data that is required. I have not tried other bulk mail applications, so am unable to compare these.

Mailchimp over the years I've used it has grown in leaps and bounds. They have added so many additional features than were previously available. They are truly an all-in-one marketing platform now. If you're a small operation and just want to add email to your marketing efforts, they're there for you. If you're a larger operation and want to start sending postcard advertisements, they can do that. If you'd good with that and want to kick up your marketing by going social, you can do that on their platform. They are truly able to be as small as you need, but also get quite large in whatever it is you'd like to do through their system.

  • Mailchimp has allowed us to communicate effectively with thousands of customers with ease.
  • Mailchimp's use during our second year of business helped us expand our list of brands considerably (almost 30% YTD) because of regular interactions that we've launched.
  • Mailchimp ramp-up time is minimal for new users so I can turn things over to junior staff - saving me time and money.
