The best software for Customer Marketing E-mails
Comments: 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.
Highly recommend!
Comments: The customer success and support team at CustomerIO have been a massive factor in my experience. I cannot express my appreciation enough. They are prompt, amiable, and always willing to go the extra mile whenever I reach out to them. I really value the CSM assigned to our account. He has not only taught me how to use Customer.io, but he's also doubled as a strategic partner in helping me bring my ideas to life through Customer.io.
Pros:
I find the product to be user-friendly and enjoyable. The campaign builder is my favorite feature as it allows me to create intricate journey flows with ease. The 'wait until' action block has been a game-changer for me as it has minimized the need for engineering resources.
Cons:
I've been using Customer.io for 6 months now and honestly, I don't have any complaints. Seems like for every issue I've had, the support team is dedicated to unblocking me. There are always ways to improve a product, but in terms of important game-changing features, they really thought of everything.
Alternatives Considered: Klaviyo and Marketo Engage
Reasons for Choosing Customer.io: Customer.io saved us money and engineering resources. It was easier to use at our current size.
Switched From: Braze
Reasons for Switching to Customer.io: Cost and level of support
Email automation tool
Comments: I don’t find this product very easy to use but it’s one of the best so far I’ve used in the email automation space.
Pros:
I liked that I could run my drip campaigns on this tool. The complexity of the drips could be managed.
Cons:
It requires a dedicated developer which might not always be possible. There should be a few automated codes.
Smooth experience
Comments: Extremely positive
Pros:
The UI/UX is very smooth and clean, and customer service is spectacular. As someone who has used many ESPs, it's very important to me that I can work smoothly without interruptions. In my career, CIO stands alone in UI/UX among competitors. Our account representative is always available for help and consultations, and is always bringing value to our relationship.
Cons:
It would be nice if there was an out-of-the-box solution for opt-in forms, but it integrates well with our third party app so this isn't a big deal. What they lack here is completely made up for in the quality of their platform and their integrations
Very powerful tool for everything related to email marketing
Comments: I'm happy with the tool and feel confident sending transactional emails or marketing newsletters.
Pros:
The platform has a steep learning curve, but once you get past that phase, it's truly powerful. Things that seemed impossible with other email clients are feasible with Customer.io. The drag and drop editor is also much better and runs much more smoothly than others I've used.
Cons:
I'd say the biggest con is that it's a bit pricey. It can also be a bit overwhelming at first because there are so many features, but you just have to push through the learning curve.
customer.io for saas
Pros:
customer.io is easy to use and very versatile. It has met all of our email marketing needs for both our web and mobile app.
Cons:
customer.io has a bit of a learning curve at first with some of the advanced/pro features like customizing email messages, deploying api triggered messages, etc.... but the interface is very easy to use and when I had questions I could always get a hold of support for help.
Good for non tech savvy user
Comments: Everything is perfect
Pros:
I like going to customer.io to crease sub segment of our users. The ability to filter user by attributes is very simple to use.
Cons:
User filtering options can be more flexible
Great software for event triggered marketing campaigns
Comments: We've been able to convert more sign-ups from trial to paid users using customer.io
Pros:
Getting set up and using customer.io was an easy experience. All our user attributes came straight via segment and we were able to target users based on their event behaviours within our product immediately.
Cons:
The one thing I dislike is the load times between pages - compared with our other platform (Hubspot) its night and day with how quickly each page loads.
This is my main email platform now
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.
The best product for email marketing
Pros:
It is very easy to use and the features are very intuitive.
Cons:
Can't think of any. But i wish they could launch new product features faster
One of the best email marketing tools I've used!
Comments: I've been using Customer.io for almost two years and couldn't be happier with our experience! It was super easy to transition from our previous email client and integrate and connect with our other software. It's been an important piece of our marketing strategy and has helped us generate upsells and new leads.
Pros:
I've worked in many email marketing tools over the years and Customer.io is by far the easiest to use for every member on our marketing team! The drag and drop tool has really helped us achieve the same brand look across every email we send - and it's easy enough that even our copywriters can create emails. No designers or developers needed!
Cons:
The only limitation is that I wish the dashboard and interface was a bit more user friendly. I feel like the image library is buried. I feel like there's so many impressive C.io features get hidden. I also wish you set your "Email Settings" in your Team Profile and those settings could be applied to every email instead of manually inputting them each time.
Alternatives Considered: HubSpot Marketing Hub, Mailchimp and Intercom
Reasons for Choosing Customer.io: We were not happy with the usability of Intercom for our Marketing Emails. The functionality of C.io was seamless and so easy to use for our entire team. As a designer, I was able to create a library of row designs tailored to our brand library so now anyone on the team can throw together a branded, well-designed email. C.io has made my job SO much easier!
Switched From: Intercom
Reasons for Switching to Customer.io: We had various demo calls with the alternative products listed above and C.io stood out to our entire team. The ease of use was unmatched. It was exactly the platform we had been looking for.
Would recommend for other health tech start ups
Pros:
Easy to use! SSO is great. Very user friendly and support is very kind.
Cons:
The HIPAA version was very expensive to sign for a small start up
Great product for Growth, Marketing and Product teams
Comments: The experience has been great
Pros:
1. Ability to customise communications using events and segments2. Responsive customer support
Cons:
1. Very expensive for a start up2. Flow for within branches still need optimisation as users can not move from one branch to another if their status/attributes changes.
Easy to learn tool, amazing support
Pros:
Despite never using Customer.io before, it was relatively easy to learn. Some features have a learning curve for sure, but I'm always able to figure them out plus the support from our CSM (shout out to [sensitive content hidden]!) and the deliverability team has been amazing. So grateful for them!
Cons:
I'd love to have more customization in the email builder, and the ability to add a drop-down question in the subscription preferences center.
Messaging savvy platform
Pros:
Email marketing has become a big thing now, where people find it more aesthetic and relevant due to it's reach on a genuine platform. Customer.io plays a crucial I'm providing a messaging platform for all such sectors to work on.
Cons:
UI/UX plays a crucial role in for any customer to find a platform easily usable and making it more interactive, so here is where it can improve it's quality
Customer.io is great! Customer service from our vendor is awesome too!
Comments: Very happy
Pros:
It just does all of the things I need it to do and most are intuitive.
Cons:
Sometimes there's weird quirks that you have to learn and figure out, but its not frequently.
Great Customer Email Tool - Content Creation Needs Improvement
Comments: 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
Customer.io for Weekly Newsletters
Comments: Overall, very happy with the user experience. It’s saved me a lot of time in developing our newsletter.
Pros:
I love using Customer.io for our weekly newsletters because it allows me to replicate the same format each week. This saves me time each week because I can just make individual tweaks to content each time, rather than having to redo the entire process. I also appreciate the metrics on open and click rate, to know what content sparks our audience’s attention and what doesn’t hit so strongly.
Cons:
I don’t like that it is difficult to copy a message from one “workspaces” to the next. I wish there was a possibility to duplicate a template across workspaces without having to recreate the whole thing. We use different workspaces to separate different audiences, but often want to send them similar emails.
Flexible but lacking some functionality
Pros:
Good user interface that's intuitive. Easy to get up and running without prior knowledge. Creating segments is quick and simple.
Cons:
Reporting tools are not very robust. For example, within Customer.io you can't sort or aggregate email campaigns to see roll-up metrics. Rather you'll need to export and sort in a spreadsheet or connect with 3rd party tools like MixPanel or Periscope.
Good for segmentation and all forms of email, SMS, and push notification campaigns
Pros:
I like how the drip campaigns are very simple to set up and implement. The segmentation tool helps to identify which customers to put into these campaigns and when they should exit the campaign.
Cons:
I like how easy it is to build emails, though there could be better design/templates for this. Additionally, setting up segments might be confusing for someone without a data background, which I have.
Customer.IO makes life so much easier with email tracking, Saved my butt multiple times!
Pros:
Customer.IO has allowed me and my company to feel confident that the correct information is being sent to the people who need it the most, our customers. The ability to view all emails that have been sent and to ensure they were received by the customer is a huge benefit to us. being able to see if a email was suppressed or bounce give the ability to ensure you can deal with the issue in a timely manner and get the info into the right peoples hands. it has also assisted us in dealing with difficult customers that claim they never received a email, however the application allowed us to show the customer that no only did they receive it they opened it!
Cons:
the only negative i could see is that the application only allows you to send 50 emails at a time and for a large customer base this makes it more time consuming.
Automate your marketing campaigns with ease
Comments: An excellent tool for Automated Marketing campaigns and the product and support teams are extremely helpful
Pros:
- Customer profile management - Hybrid HTML and Text Editor tool - Workflow set-up for Campaigns
Cons:
Uploading Customer lists manually is slightly complicated
Top Email and Push automation software
Comments: Overall great email and push notification automation software, that constantly develops.
Pros:
Customer.io is great since it easily allows you to set up and automate promotional emails , but also allows to run transactional emails at the same time. This is a huge advantage over most email automation products, b/c you can trigger a promotional email without interfering with your system emails.
Cons:
Unlike Pardot or Marketo, Customer.io doesn't have a solid automation builder. The builder is nice, but you can never see the tree of emails in a flow chart. It can easily confuse the user as you have to have a third-party software to organize the set up. It's highly recommended to put one full-time employee behind it.
Great Software
Pros:
I love customer.io! It keeps our company organized and allows us to send emails easily.
Cons:
Nothing! Everything has been very easy to use.
Extremely handy email communications
Comments: An excellent product worth its money and reputation. We use it weekly for external marketing communications.
Pros:
I loved its compatibility and easy to use system. You can sign off an email marketing campaign with a few clicks.
Cons:
Perhaps its limited design options in some cases, but its automation is still high end.
