The best software for Customer Marketing E-mails

Customer.io is one of my favorite tools at work, so easy to use that I don't even have to teach new people on my team on how to use it, they just do. I check it every day and use it as the main tool in communicating with our clients about new feature releases, new products, important changes in our software, customer marketing etc. Also it's our main tool for onboarding new users through email campaigns that are very easy to setup, with a lot of functionalities that helps us filtering the customers and offering a personalized experience. I really recommend it

Pros

I really like how easy it is to setup an email campaign and automate it according to users different attributes. We have a lot of onboarding campaigns going on in all languages and it is the best software we have with this kind of funcionality. Also, broadcasts are very simple to create and easy to track. The UX/UI of the platform is perfect, definitely the best one we have among the e-mail senders we use.

Cons

The template creation is very limited, forcing us to use other softwares and exporting the HTML code to customer.io. Also, the contact database is kind of messy, not very easy to find people, organizing contacts or filtering them.

Great Customer Email Tool - Content Creation Needs Improvement

Reviewed on 2016/03/22

We have been using Customer.io for nearly three months, and it has revolutionized the way our SaaS...

We have been using Customer.io for nearly three months, and it has revolutionized the way our SaaS business communicates with its customers. From multi-part onboarding of new customers to re-stimulation of lapsed users to announcements of new features, Customer.io has been a dream come true for our subscription business.

Building a sequence ("workflow") of emails, triggered by a particular event (like SIGN-UP or UPGRADE or CANCELLATION) is a snap. And applying it to individual customer segments is easy, though you'd better brush up on your logic (AND/OR/NOT etc.) before you construct a more exotic segment.

So, too, is the ease of constructing one-time mailings ("newsletters") to an entire group of customers meeting a certain set of criteria. Once the segments are defined, sending newsletters is quite straightforward.

In this regard, Customer.io runs circles around MailChimp, which we used to use for this purpose.

Integration with a software product like ours is quite straightforward, and Customer.io offers a nice API for updating customer profiles and posting events for those customers.

Customer.io currently falls short in the content creation department. Its text editor doesn't measure up to the rest of the application, and requires quite a bit of hand-manipulation of HTML to get newsletters and emails looking just the way you'd like them. Getting email text to wrap around a right-justified image, for example, requires knowledge of and hand-coding in HTML. And even then, the HTML produced by the text editor is not clean.

Missing, too, are functions like being able to duplicate a workflow in order to launch a slightly different communication flow to a different customer segment. Onboarding customers to two different product tiers, for example, requires that the entire workflow be created from scratch for each segment, rather than allowing the user to duplicate the workflow and make changes to suit the second segment.

Those shortcomings aside, Customer.io is a tool that shows a great deal of promise for any company that wants to communicate on a regular basis with its customers, especially when those communications need to be sequenced over a customer lifecycle.

For a recurring-revenue business, where ongoing communication is key to retention and referral, a tool like Customer.io is essential to success.

Pros

- Customer data base is very flexible, and easy to keep up to date via API
- Very powerful segmentation tool that can use customer profile fields, events, and even interaction with email to segment customers for subsequent communication
- Easy, intuitive construction and management of triggered, multi-part communications workflows
- Attractive visual reporting of emails sent, opened, clicked
- Reasonably priced, automatic scaling of pricing based on actual volume used (emails, customer profiles)
- Built-in A/B testing of email copy

Cons

- Text editor lacks power features; requires HTML in order to optimize emails
- Minimal pre-packaged layouts; layout design requires knowledge of CSS
- Lack of workflow cloning or replication creates unnecessary work

Pros

Customer.io is a pretty good, capable tool. Easy to get data in and easy to create communications and journeys for your customers.

Cons

I pay monthly and they will not allow me to right-size my usage to a lower amount until a year has elapsed. Really odd.

A game changer

Reviewed on 2023/06/05

Pros

We love to be able to act based on everything that our customers do on our platform and our website. Campaign workflows are easy to build and maintain and UI is very intuitive.

Cons

We basically manage all our customer data in C.io and not being able to having KPIs and analytics related with customer actions and events is a little bit frustrating.

This is my main email platform now

Reviewed on 2023/06/03

Pros

Customer.io is an excellent email marketing platform. I made the switch from a lesser-known (and cheaper) platform that I had been using for a few years. I can clearly see the difference now, and I'm happy to pay more for the ability to engage my customers more effectively and access a wider range of marketing features, all in one place.

Cons

Customer.io is not yet the ideal platform for my projects. One limitation, for instance, is its restricted template language.It also lacks the ability to filter and count incoming events and dynamically insert these values into emails.
