User Testimonials

Likelihood to Recommend
Constant Contact
Constant Contact is an excellent tool for sending out flyers and newsletters. However, I feel the content's appearance is typically all the same. When I receive an email from Constant Contact, I can immediately identify it - the templates usually all look the same. When sending out communications with images, it is easy to use Constant Contact and link webpages. However, the email layout is always vertical and can get very lengthy. I prefer a more flip-book approach with options to flip the page.

Talking from the perspective of a marketer at a SaaS with average. 50K email subscribers, Customer IO has been an excellent tool for us. Our requirements include sending users newsletters, marketing emails, and transactional emails, running lead-nurturing campaigns, and more. For a comprehensive use case like ours, CustomerIO is great. While it also has a learning curve, when you have such requirements, it’s worth it. I don’t think CustomerIO is the best fit if you have basic requirements like only weekly newsletter emails.

Pros
Constant Contact
  • Market segmentation is great: my main segmentation is by region because that's how our sales team is divided.
  • Lists: making customized email lists is easy and intuitive; the custom fields allow some flexibility in case our fields don't exactly line up with Constant Contact's.
  • Campaigns: creating campaigns is quick and simple. I especially appreciate the 'resend to non-openers' option. I am constantly using this feature.
  • Subject line generator: I like using the recommended subject lines. I'm able to plug in their recommended ideas, or sometimes, this feature helps me generate my own ideas.

  • 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.

Cons
Constant Contact
  • It would be nice if we had more customizable options for emails - like moving around pictures and text boxes, rather than a set spot for everything to go.
  • I would like it if multiple people could work on a document at one time. So if I'm in charge of graphics, I can get those updated while someone else is entering content, etc.

Customer.io
  • Price is quite expensive for Premium or once you get into high volumes of contacts.
  • Depending on how you'll use it, it may require some help from developers to set up.
  • Despite the support being great, you have to email them, there's not chat feature.

Likelihood to Renew
Constant Contact
There is no doubt that we are going to renew Constant Contact. We have not just invested a lot of time in learning and creating a great looking product but we have developed a strong database of information that allows us to track how we are doing for each newsletter. This supports our goals of creating products that residents desire and are excited to receive.

Usability
Constant Contact
There is always room for improvement. I don't know how they test their systems, but they should invite not-so computer savvy people to test it. If I, as an expert have problems, they need to think like the technophobe. Since I've used Constant Contact in the past as part of my former employment, I have not viewed any of the tutorials and just jumped in to work on my client's newsletter. With that said, I found some areas easy and some a bit cumbersome

Customer.io
Super intuitive and easy interface to start off with. There are not a lot of guides and the documentation is helpful but not super extensive, but even if you're a little technical, you can easily figure most of the things out by yourself. Everything is super easy to start with and the platform does not overwhelm you with a lot of options, or data.

Performance

The system seemed quite slow sometimes. Specifically, there was sometimes a delay in sends if it was during a high traffic period. There were time-outs when uploading new code for an email, and a lag in reporting analytics which was sometimes as long as 72 hours

Constant Contact
I think the overall support for Constant Contact has always been incredible; I have nothing negative to say. Our customer support representative was attentive, easy to understand, and very knowledgeable. I never felt like I wasn't a priority of his and my issues, while very small, were fixed in a very short time frame.

My experience with their support team has always been great. Very quick to respond, have an online chat, and are very helpful. They helped me resolve any issues I've had every time in a professional and knowledgeable manner. We've now switched to another tool, and I can't even compare the service level we get there to customer.io

Implementation Rating
Constant Contact
Implementation is very easy for someone who wants to send out the “batch and blast” type newsletters. If you want to use their templates with no customizations, the product works fine. However, the more customizations you get into involving link color, etc, that’s where things can get tricky for someone who may not be familiar with coding

Alternatives Considered
Constant Contact
Constant Contact is much more intuitive for people who are not tech-savvy. Also, while sendgrid offered more options in it's drag and drop interface, it displayed differently across different email clients, which made it very cumbersome to use. It also took much longer to upload contact lists and it was harder to manage existing contacts. Performance in sendgrid was much slower as well, and the Preview feature was quite buggy. Our team initially chose sendgrid because of the integration options that it's API offered, but we ultimately switched to Constant Contact because it was much easier to build campaigns and better suited our requirements.

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 any other drip email provider because they really have all the key elements you need to make it work.

Very reliable in sending email campaigns and controlling the recipients so that no contact is sent the same email more than once, even if they are on a resent list

Return on Investment
Constant Contact
  • I have had nothing but positive impacts from using Constant Contact.
  • The church is large, and there are many subgroups and axillary groups within the church. Setting up specific groups based on responsibility, interest, member goals, and service needs allows me to send information quickly, saving valuable time for other tasks.
  • Constant Contact allows leadership to stay personally engaged with the members I work with, without over-taxing my time. It feels so seamless.

  • Positive impact on the sales side. I'm not sure about the specific ROI (you have to include the designer and the time it takes to set up) but you certainly get back the investment in a few months, once you are able to scale your email marketing.
  • Customer experience is way better by having more segmented, contextual and accurate messages sent to them.
  • Integration is costly and it will take several days or weeks to be fully achieved. Expect to invest some money on this.
