Alternatives considered [Outreach](https://www.capterra.com/p/159318/Outreach/) Reason for choosing Customer.io The Startup Plan is amazing Review Source VR Verified Reviewer Growth Information Technology and Services Used the software for: 1-2 years ### "A Great Marketing Automation Platform with an amazing support team" December 30, 2022 5.0 We are mainly using C.io for lead nurturing purposes. We are quite confident with the fact they will improve their product with better reporting features. Pros I've tried many marketing automation tools and is clearly making a difference in terms of UX, documentation, and customer support! Cons It can be quite complex sometimes according to your needs but thanks to their great UX, documentation, and support team, you'll find solutions. There are some missing features (eg. cohort analysis) but hopefully, they are working on it. Switched from [SendGrid](https://www.capterra.com/p/204113/SendGrid/) We needed a tool with true Marketing Automation Platform features. Review Source LH Ludwig H. Product manager Internet Used the software for: 2+ years ### "Best customer engagement tool" June 27, 2023 5.0 Pros Possible to make super complex flows. Pretty much replaces doing everything custom in our backend. Cons Nothing to dislike really. A bit complicated to use for new users, but probably because it's so powerful. Review Source PP Paola P. Sales Dep Used the software for: 6-12 months ### "A flexible and customizable tool that is easy to use and set up" May 1, 2018 5.0 This is an amazing tool that everyone looking to take their marketing efforts to the next level should get familiar with. Pros The flexibility that offers, I yet have not been able to see in any other tool. It is very easy to set up and its lightweight user interface is robust yet simple to understand. On top of it, customer support rocks! I was answered right away for every little question that came up, so I didn't feel alone while working to set everything to my requirements. As for the features, I love the customer profiles: They are based on the email behavior of the users, and can also be adapted to match in-app behavior, if that's what you require. On top of it all, I love the price! Great value for the money. Cons I did need to triangulate some functions through Zapier because the tool did not offer them, such as gmail integration and Facebook triggers. Not sure if this is a con though, as Zapier does open up a whole new landscape of possibilities, but I guess those functions were not initially included in the tool so that's why I'm talking about them in this section. Other than that, no cons. Review Source NM Nessim M. Head of Marketing Marketing and Advertising Used the software for: 2+ years ### "Great Tool for Marketing Automation" September 16, 2022 5.0 Great tool. Not made for beginners but if you are willing to spend time on masterising, I highly recommend. I have been using it in several companies for the past 5 years. Pros \- Easy to use - Integrate with Segment - Constant updates Cons \- Could be complicated if it's your first Marketing Automation tool but you get the hand of it quickly Alternatives considered [HubSpot Marketing Hub](https://www.capterra.com/p/171840/HubSpot-Marketing/) Review Source CB Christie B.

Pros I like you can easily integrate with other platforms, with the open API makes it so very easy! Cons Nothing! It has just been amazing, I love this software Alternatives considered [Zoho CRM](https://www.capterra.com/p/155928/Zoho-CRM/)[ActiveCampaign](https://www.capterra.com/p/79367/ActiveCampaign/)[Mailchimp](https://www.capterra.com/p/110228/MailChimp/)[Marketo Engage](https://www.capterra.com/p/75130/Marketo-Lead-Management/) Reason for choosing Customer.io Cost, had every feature we wanted, easy to use, scalable. We have over 10,000,000 contacts and the other systems couldn't handle that easily. Switched from [HubSpot CRM](https://www.capterra.com/p/152373/HubSpot-CRM/) HubSpot was just cumbersome, not easy to use, could not integrate with our other email sender and was so very expensive.

Digital Marketing Intern Financial Services Used the software for: 6-12 months ### "Good for segmentation and all forms of email, SMS, and push notification campaigns" July 13, 2022 4.0 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. Review Source SR Simon R. SOE CRM Manager Computer Games Used the software for: 6-12 months ### "Versatile connective messaging platform" January 5, 2023 4.0 Pros The ability to easily integrate and connect with other software to support a singular customer profile view across multiple systems.

Application Support Analyst Used the software for: 1-2 years ### "Customer.IO makes life so much easier with email tracking, Saved my butt multiple times!" June 25, 2018 5.0 Pros 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. Review Source Dana H. CEO, Co-founder Real Estate Used the software for: 1-2 years ### "Best customer service" November 6, 2016 5.0 Honestly -- they care so much about their customers.

Also, the reporting could be more detailed Review Source Umang M. Data Analyst Information Technology and Services Used the software for: 1-2 years ### "Messaging savvy platform " February 22, 2023 4.0 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. plays a crucial I'm providing a messaging platform for all such sectors to work on.

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. Review Source Chris V. President Design Used the software for: 2+ years ### "An awesome way to connect with customers" April 11, 2018 5.0 Pros When we build new apps or startup prototypes for clients, is one of the most reliable tools in our stack. It makes customer communication SO easy and intuitive, allowing you to easily group customers into segments, trigger communications based on specific events, etc. The API is easy to use too, and makes it really easy to integrate with your app at a deep level. I couldn't imagine life without it! Cons The only real complaint is pricing. If you are bootstrapping and don't have a ton of money to spend, it can be pretty prohibitive.

It has a wide range of features and easy to use templates. Cons The lack of native integrations to CRMs is a big negative but they do work with integration tools like Zapier. Review Source SW Sebastian W. VP Marketing Insurance Used the software for: 1-2 years ### "Top Email and Push automation software" April 22, 2019 5.0 Overall great email and push notification automation software, that constantly develops. Pros 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, 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.

Pros We were using an email service provider and a Figma design file to manage and sync our customer messaging flows. We needed a proper solution, so we compared a lot of companies, and seemed to be the most reputable. Cons The hurdle to learn and use the platform was a bit high, and there were areas of UX that could have used some improvement. But at the end, the platform is so quick and now as we are used to it, it does exactly what we need it to do.
