Considered Multiple Products
Constant Contact
Chose Constant Contact
Along with Constant Contact, I've also used Mailchimp, Klaviyo, HubSpot, and others -- but these are the main email tools I felt that it could compare to overall.
Chose Constant Contact
Mailchimp is pretty comparable in a lot of ways to Constant Contact, but Constant Contact just continues to win when it comes to deliver-ability and user-interface. It's clean, simple, and intuitive.
There are other platforms like ActiveCampaign and Klaviyo that have some …
Chose Constant Contact
Constant contact was perfect for our needs for many clients, it wasn’t overly robust, but powerful enough to see strong ROI. With regards to the competitor tools, amongst standard ESP there’s not a huge difference as they all essentially work the same, it’s just about pricing …
Klaviyo
Chose Klaviyo
Klaviyo is very user friendly compared Mailchimp, Privy, and Constant Contact though there is a learning curve for some aspects of it especially the automation aspects it is well worth learning the ins and outs of Klaviyo. We are pretty happy with Klaviyo which does everything …
Chose Klaviyo
For ecommerce, MailChimp and Constant Contact do not compare with Klaviyo. While their builders are not different, and the ability to create pleasing emails are similar, the targeting, segmentation, and data available are worlds apart. That said, I have not used MailChimp or Con…
Chose Klaviyo
Klaviyo is more robust that Constant Contact and AWeber, yet no less easy to use. It's also every bit as feature-rich as Active Campaign, but easier to use. (in my opinion) They're customer support isn't as good as Constant Contacts, but the tradeoff is a more sophisticated ESP …
Chose Klaviyo
Klaviyo compares favorably to other similar products but really stands out when looking at specific integrations. If you're running Shopify then Klaviyo makes too much sense when deciding on a CRM system. It's literally built to work with the Shopify platform and makes life …
Chose Klaviyo
We selected Klaviyo in 2018 when they were disrupting the space. They provided a lot of offerings for a value price.
Chose Klaviyo
Klaviyo provides much more insight into customer data than other email marketing software. For this reason, they are much stronger for e-commerce businesses as the data it provides is very beneficial for e-commerce businesses.
Chose Klaviyo
Better UI and functionality (segmentation, campaign builder, reporting)
Chose Klaviyo
Klaviyo is an excellent resource for aspiring marketers who want to be more data-driven.
Chose Klaviyo
I have used several platforms and by far the one with the most design features is Klaviyo. It lets you edit both desktop and mobile versions which is a must considering most people look at their emails on their phones. It is also great at segmenting and creating flows. I do …
Chose Klaviyo
Honestly Klaviyo is far better than the others. Having worked with others they don’t provide half of what Klaviyo does. Klaviyo provides better reporting, better analytics and helps us reach the customers we want to reach at all times. When you want to work and step up email …
Chose Klaviyo
Klaviyo is much more advanced than the other ones we evaluated. From the user interface to the triggers and segmentation. It also integrates with far more apps than the other two platforms. We are able to do some unique things with Klaviyo just because it integrates so well …
Chose Klaviyo
Klaviyo has been recommended to us by a customer who was working with the company for a month. The company who has recommended us to the service has reached the same conclusion - do not even bother with Klaviyo as on the other side of the screen there's a company you cannot …
Chose Klaviyo
We selected Klaviyo primarily for its e-commerce automation capabilities. It was the best platform we evaluated for sending out targeted and personalized emails and SMS campaigns based on Customer online purchase history and interactions with online products.
Chose Klaviyo
I've mostly used Mailchimp in the past for email marketing campaigns, albeit very basic ones. I did look into what options there were for automation, and there were some very basic options like transactional emails and welcome series flows, but there was very little …
Chose Klaviyo
Klaviyo makes a/b testing drip campaigns very intuitive to the average, non-technical user, which is something that other platforms fail to do. While more expensive, it more than pays for itself due to the ease of testing. You can test and deploy content faster and in a more …
Ontraport
Chose Ontraport
We initially selected Ontraport based on the seemingly quality reviews. While they are priced much higher than their competitors, we initially took that as a positive. Perhaps the price tag hinted at better service, more robust features and superiority deliverability.

None of …
Chose Ontraport
I really liked the robust features presented in a way that made sense to me. I needed a higher level system that I could understand how to use with little or no ramp-up time.
Chose Ontraport
Infusionsoft - I chose ONTRAPORT over Infusionsoft because I could make it match up to my clients processes easier. I value the flexibility. On the flip side, Infusionsoft has some eCommerce integration and pre-configured solutions that are appealing.

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.

Klaviyo
If you are a big business, with thousands of customers, Klaviyo can be the thing that really kicks up your marketing. The amount of data you can collect and use can be invaluable. But if you don't have the time or money to devote to the marketing team, then you might waste money on data that you might not ever act upon

Ontraport
Here are some cases where Ontraport is well suited : - When writing emails, you can easily access to preview, manage the changes and go back to what you did before - When using automations, if there's an error, you can go back to a previous version of it. There are also some super tools that allows to see where a clients is on an automation without having to go through the all automation. It is less appropriate when you are several colleague that are addressing an issue on an email/automation as it doesn't allows you to be multiple person on the item.

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.

Klaviyo
  • Very easy to setup Klaviyo with Bigcommerce for email & SMS capture, comes with templates that are simple to edit and publish.
  • Very easy to set up Klaviyo with other 3rd party apps like Yotpo Reviews and Loyalty, giving you easy access to send emails based on loyalty points or asking for a review.
  • Automated campaigns are a breeze! They come with preset templates to get started quick. Including a Welcome Series, Cart Abandonment Series, Lost Customer Series, and Browse Abandonment Series among others.
  • The platform is easy to navigate and use without having to spend time learning from videos or help files, we were able to just jump right in and use it.
  • Great features like targeting based on anything available in your data, including products purchased, loyalty standing, interactions, etc.

  • Dashboards for our daily stats.
  • The email follows up and broadcasts are simple and easy.
  • Sales and marketing can now see the impact they have working together. Nobody can point finger anymore.
  • They have the best customer support. I can't tell you how many times they have walked me through the problems that I created.
  • Amazing email inboxing.

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.
Read full review
Klaviyo
  • At times the platform isn't as intuitive as you would like. Take the time to be onboarded and play around in the platform to get the hang of things. Utilize Klaviyo's resources and attend their live training sessions to help navigate the platform and implement best practices they recommend.
  • Can be pricey depending on company and email list.
  • Customization is limited at times. The brand font we utilized on all branded content wasn't available through Klaviyo. Previously we would have to go through the back end to implement our branded font, import our font, or create content on another platform to utilize our font.

  • Wish they had more options for their forms. Would really like to use multi-step forms.
  • A lot of times their forms load slowly on the website. Would like to see them speed up their services.
  • Their broadcasting options are legacy. There are better options out there for sending broadcast messages.

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.

Klaviyo
Klaviyo is simply a great solution for e-com email marketing & customer relationship management:
  1. User journey visibility: We can see our clients' customers on their individual user journeys (open email, site visits) to better understand and accommodate your customers.
  2. Flow automation: Creating automated emails that follow up with new leads, those who abandoned carts, purchased.
  3. Email design: So easy to use, and more friendly than some other visual builders that we've used.
  4. Metrics visibility: We can see our clients' metrics very easily and adjust efforts accordingly.

My client was already using Ontraport and had a decent investment in the tool. As soon as we turn around the revenue situation with my client's products, we will be ditching OAP immediately, despite the significant re-implementation cost we are going to face moving to a new system. I am part of a high-end, professional marketing group, and the overwhelming sentiment with these other professionals is that one should run away from this as fast as humanly possible. I thought their words were just ungrounded opinion, and I deeply regret that I did not heed them more closely before sinking still more time and effort into OAP.

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

Klaviyo
The only reason why I did not give it a 10/10 is that it cannot distinguish purchases that came through subscription recharges instead of purchases that were driven directly by email sends. Other than that, the automation qualities, design features, and segmentation options make this an incredible email platform, and I am very happy with it

Ontraport
The software is just easy to use. The UI is fairly intuitive. The help system is pretty good. I find it is pretty quick to get my work completed and if I don't document my things well, I can always figure out how I did something when I need to make changes. When I have a problem the tech support is easy to deal with and when things need to get escalated they are resolved quickly.

I think the overall support for Constant Contact has always been incredible; I have nothing negative to say.

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.

MailChimp was adequate for basic email marketing, but Klaviyo offers a far superior experience with its advanced segmentation, automated flows, and deep integration with Shopify. Klaviyo’s behavioral data analysis and A/B testing provide more precise targeting, while its robust reporting tools help us understand customer preferences better. Overall, Klaviyo’s features are more tailored to our needs, making it a more powerful and effective platform.
