"Herramienta efectiva de marketing"

What do you like best?

Permite automatizar campañas de marketing y enviar los correos a un gran número de clientes potenciales. Se puede integrar con otras herramientas existentes, enviar correos basados en eventos.

Otra utilidad que me gusta es que puedo saber cuantos clientes han abierto un email, también la facilidad de distribuir la publicidad en un breve periodo de tiempo.

What do you dislike?

Los informes podrían ser más completos, por ejemplo poder ver analíticas y estadísticas sobre los correos enviados. Otra desventaja con respecto a otros programas pueden ser las plantillas, no son especialmente llamativas o atractivas, y no permite customizarlas del todo, lo que puede llegar a afectar a campañas de marketing.

Recommendations to others considering the product

Si buscas una herramienta con varias capacidades para enviar emails a numerosos contactos, publicitar tus productos, debes darle una oportunidad ya que cumple con estos requisitos y más.

What business problems are you solving with the product? What benefits have you realized?

"Customer.io—Powerful and Personal"

What do you like best?

Customer.io has two great things going for it. First, the platform is incredibly flexible. If you dream up an email campaign, there's a way to make it happen with Customer.io. Second, their customer support team is beyond compare. They provide rapid, personalized assistance and take your inputs to heart. I smile every time I see a new feature roll out that solves I problem I previously brought up with the support team.

What do you dislike?

I mainly create campaigns and don't deal as much with logging user data to Customer.io, so I have to turn to my own development team to get new information logged, which can take some time. Writing campaign triggers based on Liquid code also involves a bit of a learning curve.

What business problems are you solving with the product? What benefits have you realized?

Customer.io lets me automate all of our student-facing messaging, letting us provide accurate and timely information to our student body without the hassle of combing through endless streams of student data. With Customer.io, we're able to keep more students on track with their curriculum and improve student success. And whenever we need to add a new campaign or tweak an old one, Customer.io has the tools to make that possible.

"Very Powerful, but not always Intuitive"

What do you like best?

I like that you can pass custom data from your own product or users into Customer.io for use in segmenting users and in the copy of the emails you're sending. Even cooler is the ability to automatically trigger these campaigns based on a user's entrance into a segment or a specific action they take in the product. That's extremely powerful for our enterprise product.

What do you dislike?

The UI makes it somewhat challenging to navigate from start to finish through creating a campaign, the template editor has some big limitations, and there's no easy way of managing a larger number of campaigns (either with better previews or with grouping that's more specific than just "Triggered")

Recommendations to others considering the product

The competition set for this product really varies depending on your needs. I think customer.io is really powerful when compared with something like mailchimp or just sending gmail. But, I do think there are some strong contenders in the multi-channel automation outreach space that give customer.io a run for its money (Autopilot comes to mind).

What business problems are you solving with the product? What benefits have you realized?

Customer.io helps us send automated platform emails without having as much technical maintenance of our own. It also helps us scale our product-centric marketing efforts. I think we can actually realize even further benefits from the product, and we're working on review those opportunities as we speak!

"Email - done right."

What do you like best?

The seamless integration between Customer.io and Segment has allowed our company to send emails intuitively based on specific triggers, filters, and logic. They also provide the tools we require for internal communication within Slack, SMS, Trello and more!

With Customer.io emails are the product of logic, not assumption. What more can you want?

What do you dislike?

Would be very nice to include a built-in email template builder. A WYSIWIG editor alone could suffice. As of now I am having to have these templates coded and then input into the source code section.

What business problems are you solving with the product? What benefits have you realized?

Customer.io is re-defining the value of our emails. When you're a consumer and are identifying with a brand, it's important you aren't bombarded with emails at random, based on assumptions of the users journey. We also use Customer.io for internal notifications via Slack, SMS etc..

With Customer.io, I am able to sync real-time user data and setup email logic which is then used to communicate with users optimally. In understanding this, Customer.io has empowered us to setup campaigns for several key points in the user journey (e.g. onboarding, upselling, crosselling).

"An Effective Email Marketing Tool"

What do you like best?

What I like best about Customer. io is the possibility of personalization. There are many ways to personalize this email marketing tool. Segmentation is one of them: If you integrate Customer with your CRM or/ and other platforms it gets even more interesting. Let's say you have several campaigns for different products and specific audiences established in your CRM. By integrating Customer with your CRM you can send personalized campaigns to each audience and even pick which ones to track and how (converted rate, clicks, etc).

What do you dislike?

The biggest disadvantage that Customer. io has Vs. other email marketing tools is the fact that their templates are not especially attractive. The templates are just functional. They don't offer beautiful graphic options, not even the fonts have many possibilities. Which is in a way a limitation for marketing campaigns, but probably not a big problem for follow up emails.

What business problems are you solving with the product? What benefits have you realized?

I use Customer. io at least twice a week. We communicate with our customers in an effective way. We also review which campaigns, newsletters, etc. are working better. The options we have regarding the segmentation is key for us.

"Friendly and direct messaging to customers "

What do you like best?

Being automatic is necessary nowadays and with this software I have the information of my clients at hand to improve the interaction between the brand and them. What I like most is the ability to visualize the behaviour of each user in the face of the strategies implemented, the progressive change and so analyze what to improve.

What do you dislike?

I have tried other similar software more friendly when learning to use them. Also, I've had problems configuring it and setting up the right responses you need to send based on user behavior.

Recommendations to others considering the product

Pay attention to all the available options, it is important to know what you want to do before you enter the platform. When you have access you will have a lot of messages from your customers to handle and it can be a little overwhelming.

What business problems are you solving with the product? What benefits have you realized?

Interaction, brand loyalty and establishing new strategies to increase sales.

"Hard to Setup, Easy to Use Later"

What do you like best?

- Lightweight and powerful UI

- Very fast

- Good price

- Email Layouts easy to configure

- Easy to define goals, workflows, triggers...it's so "smart"

What do you dislike?

- Very hard to configure unless you are very technical. Not tracking anonymous users suck (we had to build a workaround on that)

- Stats could be improved, you won't get too far apart from standalone reports

- Exports are a bit poor

- Not that many integrations

Recommendations to others considering the product

Get ready to suffer on the setup. Is hard. If you want to track anonymous users, it's very complex and not elegant.

But beneath that, it's very powerful. For us, workflows have infinite ROI (well, not that much, but A LOT).

What business problems are you solving with the product? What benefits have you realized?

We use it to send behavioral emails (abandonment carts, welcome emails) and newsletter emails.

It's very easy to use, the cost per email and user is cheap, the interface is smart, fast and lightweight.

It is versatile, you have many options to segment. It's mainly an empty container with infinite options. It may seem overwhelming but for marketers it's the holy grail.

"E-mails made easy"

What do you like best?

This platform is WAY easy to navigate compared to what we were using beforehand. The UI is straightforward and creating a campaign with little time that looks sleek is not longer a task I don't look forward to. Their customer service is incredible, along with all of the resources available through their site to answer any questions you might have about information location or functionality.

What do you dislike?

The templates leave more to be desired than those from competitors, but the ease of creating and sending out these e-mails makes up for the limitation. You can always design your own email template and input the source code.

What business problems are you solving with the product? What benefits have you realized?

I use Customer.io about once a week to send out emails to our followers, and we are able to see which campaigns yield the best traffic results and sales. It's helped us tremendously with honing in and targeting our specific demographics while giving our company a professional look.

"Very powerful email automation tool"

What do you like best?

Customer.io has got some really powerful features such as advanced segmenting and liquid templating for email templates. The Slack integration is also really useful to get notifications about anything that's going on in your product/business.

On the top of that, the support is great!

What do you dislike?

Not much. I've already submitted my feedback to the support team about one or two little details and they have been very responsive about it.

What business problems are you solving with the product? What benefits have you realized?

Customer.io allows us to automate all of our users' email onboarding and nurturing. We can adapt our emails to every segments of users.

"Solid experience with Customer I/O"

What do you like best?

The customer support team was incredible, always offering quick advice and even custom engineering support.

What do you dislike?

Uploading custom email segments was not as easy as we would have liked and often resulted in emails to customer support. In reality, 80% of the emails we service are transaction and can be support with the pixel, but most systems can't support the super custom logic we use to power some lists.

Recommendations to others considering the product

Make sure you have clear use cases in mind and are biasing towards transactional email

What business problems are you solving with the product? What benefits have you realized?

Customer I/O was being used as both our transactional and email promotions platform. The integration was incredibly easy, as was onboarding. We were up and running within days of signing the deal.

"Great platform for custom emails based on sophisticated triggers"

What do you like best?

Customer.io is very easy to use. It has a graphical interface for programming email sending rules that is relatively self-explanatory.

What do you dislike?

So far, I haven't found anything about it to dislike.

Recommendations to others considering the product

The difficulty in setup will vary depending on how technical your implementation is - make sure you have a dedicated engineering resource to puzzle through the steps.

What business problems are you solving with the product? What benefits have you realized?

Customer.io allows us to automate and customize communications for enterprise clients of our white-label employee engagement product. It is fast, flexible, powerful, yet still simple enough that training new staff is relatively easy.

"Love it!"

What do you like best?

I love the Ruby API! https://customer.io/docs/api/ruby.html We have some custom events that are not available from the JS snippet, so being able to add our own events through the API has allowed us to set up some awesome drip campaigns through Customer.io.

Special mention for their adorable mascot.

What do you dislike?

I haven't run into anything that I didn't like so far!

Recommendations to others considering the product

Use the segment integration! It makes getting your users into the system take like 20 seconds and once you have Segment set up in your system, any new integrations (like Customerio) don't need to change your codebase.

What business problems are you solving with the product? What benefits have you realized?

We are running multi-touch campaigns as part of a customer advocacy program and their 'Triggered' campaigns work incredibly well for this. Their segments + a campaign makes this really easy.

"Great comms tool"

What do you like best?

I like the flexibility the service provide, nice and clear API and performance. The recent feature to copy items from one campaign to another is awesome.

What do you dislike?

There is some lack of retry policy configuration, campaign can not be logically grouped (directories/sub-directories).

What business problems are you solving with the product? What benefits have you realized?

I use customer.io to send significant amount of automatic comms to customers (~20K emails and SMS per day). The service is used to send marketing comms, reminder comms, etc.

"Gran aplicación"

What do you like best?

Es una herramienta digital que tiene todo lo que necesita. Ofrece automatización, sus mensajes se sentirán más personales cuando estén perfectamente sincronizados y activados con un avanzado motor de reglas. Crea grupos de personas similares usando información que usted sabe acerca de una persona, o características usadas para informarles de mejor manera. Customer.io ofrece además, información de perfiles de usuarios con un simple click usted podrá estar al corriente de todo lo que ese usuario ha hecho y como ha interactuado con los mensajes que le ha enviado. Por lo tanto, es fácil medir su éxito. Finalmente su diseño y personalización permite crear su propio código HTML o usar el de ellos con el uso de plantillas.

"Poorly Designed, Unwieldy Email Platform"

What do you like best?

Not much. It does have the functionality to set up email campaigns, including drip campaigns. And it does have a basic email editor, allowing you to play with the layout of your email. But beyond having the 'basics,' it is not user-friendly and overall not well-organized.

What do you dislike?

First, it isn't user-friendly. The UI is not intuitive, so it takes longer to find what you're looking for and accomplish what you're trying to do (compared to other email platforms I've used, such as MailChimp and Constant Contact). Secondly, the organization of 'environments' makes it difficult to manage one master list of email subscribers. Customer.io doesn't allow different 'environments' to interact with each other, nor share any data -- which can make it difficult to navigate subscriber lists, difficult to assess for duplicate subscribers, and difficult to report on email campaigns and analyze comparisons. The basic email editor is not user-friendly, and often slow to load. This platform does give you the ability to edit the HTML of an email directly, and I ended up directly editing the HTML nearly all of the time, in order to avoid using the clunky and confusing editor they provide. It seems like this platform can do the basic email functions a marketer would ask of it, but the organization, layout, and overall UI of the platform make it so cumbersome to use that it's far more frustrating to the user than helpful.

What business problems are you solving with the product? What benefits have you realized?

Benefits include being able to send emails, being able to see stats after email campaigns are sent. The benefits don't outweigh the flaws in the platform.

"Brilliant way to lighten the load for developers"

What do you like best?

I love the fact that, as an engineer, I'm not constantly having to build specific product for our growth team, sales teams, customer service team, etc etc.

What do you dislike?

There's not much that I dislike. I guess if I had to come up with something, it would be the steep cost. Well worth it, but the cheapest tier is currently $100.

Recommendations to others considering the product

Send your data to segment and have that forward along to customer.io

What business problems are you solving with the product? What benefits have you realized?

We use it to segment different email campaigns, notify members of bookings, receipts, pretty much any action based email trigger. It's been a time saver and engineering resource saver.

"Email platform "

What do you like best?

Customer.io is great because it allows us to be more of a multi-channel organization where we can broadcast over different platforms - email and SMS - while keeping all of our customer data in one place.

What do you dislike?

Some features are clunky and it feels like you have to do more manual work. There are more full features for email, but you can't apply them to SMS.

What business problems are you solving with the product? What benefits have you realized?

Being able to have one system in place for multiple communication channels, and it helped reduce cost by consolidating.

"Powerful, but not user friendly "

What do you like best?

I do understand that this tool has a lot of power. It can do a lot of things that competitors like MailChimp can't do.

What do you dislike?

However, I can't say that it's very user friendly. At least not at a high level. Once you get into the software and are comfortable with it, then it's manageable. But it's difficult to just pop right in and know how to use it.

Recommendations to others considering the product

Make sure you have one person on staff who knows the product really well. You'll have to have someone who is able to teach the software to others.

What business problems are you solving with the product? What benefits have you realized?

We're able to customize our email templates and create drip campaigns. Our favorite feature is the ability to A/B test email subject lines.

"Easy integration and setup"

What do you like best?

If you're looking to send emails based on user behavior this is one of the best implementations I've seen. It's also really easy to integrate with as a developer.

What do you dislike?

It would be nice if Customer IO supported pulling data from external sources also. It would save us lots of development time.

Recommendations to others considering the product

Switching to behavior based emails is excellent for conversion but it does require a good amount of engineering involvement to get the data you need.

What business problems are you solving with the product? What benefits have you realized?

Customer IO lets us send behavioral triggered emails that are just impossible with many ESPs.

"Better than mail chimp and cheaper "

What do you like best?

I like the ability to sort contacts easily by where they are and the ability to set contacts to different aspects of customers such as, repeat orders, customer service etc..

What do you dislike?

There isn't much to dislike. Maybe slow implementation of new features but it seems it takes longer to ensure quality. Quality over quantity

Recommendations to others considering the product

Split use with mail chimp to obtain all features at a low price. Soon enough this will take over mail chimp.

What business problems are you solving with the product? What benefits have you realized?

We used mail chimp which could get confusing for new employees in departments. With this constantly rolling it became a. Non issue and mail chimp is reserved for our seasoned professionals. This may very well fully take over with some work.

"The best non marketing automation marketing automation tool"

What do you like best?

I'm an early customer of Customer.io and am a big fan. While they don't necessarily bill themselves as "marketing automation", I have found that Customer.io can serve the role of a traditional marketing automation solution with trimmed down (but thoughtful) functionality at a great price.

What do you dislike?

It takes some time to get to know how to use it, but I guess it is just that triggered campaigns are not very easy to set up in general.

What business problems are you solving with the product? What benefits have you realized?

Increasing conversions, decreasing churn rate by making customers aware of the extent of our services

"Good tool for lots of email"

What do you like best?

pricing model lets us send an incredible amount of emails to our customers.

What do you dislike?

no html wizard to develop emails so it's difficult to create awesome visual emails without a lot of work

Recommendations to others considering the product

Customer.io lets you segment your database and create trigger campaigns so you can send the right email at the right time. The analytics are not robust enough so you have to do a lot of digging to find the answers you want.

What business problems are you solving with the product? What benefits have you realized?

connect with our customers and increase engagement. We can send many targeted emails to customers to encourage faster, and more successful on-boarding.

"It's fine - but really confusing to do basic tasks"

What do you like best?

Great APIs and automation potential, but doing small basic taks is tough

What do you dislike?

Because everything is tied to a customer.io ID, you cannot actually use email as a way to upload and send newsletters easily. You need to walk from email to customer.io ID, import that, then try to make an email newsletter.

Recommendations to others considering the product

There's a steep learning curve

What business problems are you solving with the product? What benefits have you realized?

We try and use it for all customer communication, but it's not just all programmed, sometimes it's ad hoc and this is unhelpful.

It works. There are no glitches and they have made an effort to update their backend systems.

Doesn't seem innovative and the WSIWYG capabilities are quite limited.

Recommendations to others considering the product

Lots of choices in this crowded marketplace.
