Constant Contact
Chose Constant Contact
Constant contact is the winner. It has all the features & functionality we want, and it is very user friendly.
Chose Constant Contact
Much easier to use than Vertical Response, a little less easy to use than Emma but also much simpler to customize
Chose Constant Contact
Constant Contact has long been an industry leader for email campaign and list management. It's reliable and a great go-to for many of our clients. MailChimp is most likely its biggest competitor in my opinion, giving Constant Contact a literal run for its money with equivalent …
Chose Constant Contact
Constant Contact and Vertical Response were on my shortlist. Ultimately I chose Constant Contact because of budget and functionality.

VerticalResponse
Chose VerticalResponse
I think Vertical Response is a lot more user-friendly than Constant Contact and allows for more features that Constant Contact does not. I like the email WYSIWYG feature better on here and it allows us to preview our emails before we send them out to our entire customer base.
Chose VerticalResponse
Vertical Response is most akin to Constant Contact. No frills, agile, easy to use. The one advantage that it has over Constant Contact is that you don't need to be locked into a month-to-month plan, which is what I needed. Salesforce and HubSpot aren't fair comparisons--these …
Chose VerticalResponse
In addition to using Vertical Response personally I also manage email marketing for clients that already use Mailchimp, Robly and Constant Contact. While most of these platforms all offer similar features I choose Vertical Response first if the client does not have a platform …
Chose VerticalResponse
Vertical Response was already in use when I joined the organization. It was selected for affordability. In comparison to other email marketing platforms, it was harder to use for an end user, but we were able to hire a developer to create some custom templates, and that worked …
Chose VerticalResponse
VR, MailChimp and Constant Contact all provide similar experience and provide the same function. I use many different tools.
Chose VerticalResponse
Constant Contact, MailChimp. Vertical Response covered our basic needs - contacts management, newsletter and marketing email activity analysis, templates/wizards, etc. and was free for non-profits up to 10,000 contacts/month.

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.

Optimizely
I think it can serve the whole spectrum of experiences from people who are just getting used to web experimentation. It's really easy to pick up and use. If you're more experienced then it works well because it just gets out of the way and lets you really focus on the experimentation side of things. So yeah, strongly recommend. I think it is well suited both to small businesses and large enterprises as well. I think it's got a really low barrier to entry. It's very easy to integrate on your website and get results quickly. Likewise, if you are a big business, it's incrementally adoptable, so you can start out with one component of optimizing and you can build there and start to build in things like data CMS to augment experimentation as well. So it's got a really strong a pathway to grow your MarTech platform if you're a small company or a big company.

For businesses requiring advanced email marketing features like sophisticated automation, in-depth analytics, and extensive customization, VerticalResponse might fall short due to its limited featuresVerticalResponse is ideal for small businesses or freelancers who need a simple, straightforward email marketing tool. Its ease of use and basic features make it suitable for those without extensive technical expertise in email marketing

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.

  • The Platform contains drag-and-drop editor options for creating variations, which ease the A/B tests process, as it does not require any coding or development resources.
  • Establishing it is so simple that even a non-technical person can do it perfectly.
  • It provides real-time results and analytics with robust dashboard access through which you can quickly analyze how different variations perform. With this, your team can easily make data-driven decisions Fastly.

  • I love the ease of list builder because we often times have a lot of data to import. It would be simply impossible without this tool, considering the amount of customer data we have for any one given email.
  • We really enjoy the ease of use of the HTML wizard as well. It helps even a novice be able to make a beautiful and attention grabbing email.
  • The dashboard is functional and easy to find when you need with a quick search.

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.

  • JavaScript is hard to implement sometimes especially for JQuery elements
  • ROI reporting should be part of the overall experimentation reporting
  • CMP integration: where we can easily show status of test on the HPT request
  • CMS integration
  • More widgets like social proof banners, etc.

  • The type face is small. Not sure if this is to avoid overwhelming the reader, but I could see this being an issue with vision-impaired people or people who don't see small print well.
  • Sometimes I find it takes multiple clicks to make one simple change. I wish there was a search field at the top of the screen that allowed me to jump directly to a client's entry to update it there.

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.

I rated this question because at this stage, Optimizely does most everything we need so I don't foresee a need to migrate to a new tool. We have the infrastructure already in place and it is a sizeable lift to pivot to another tool with no guarantee that it will work as good or even better than Optimizely

Product is easy for both technical and non-technical people to use. A cost effective solution for sending out large number of messages. We can manage unsubscribes by individual accounts, so we can have multiple multiple accounts combined to maximize our buying power on credits. Effective API for sending/receiving data makes tool a valuable asset.

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

Optimizely Web Experimentation's visual editor is handy for non-technical or quick iterative testing. When it comes to content changes it's as easy as going into wordpress, clicking around, and then seeing your changes live--what you see is what you get. The preview and approval process for sharing built experiments is also handy for sharing experiments across teams for QA purposes or otherwise.

I truly love this product. We are moving to an all-in-one system next year and my greatest fear in doing so is how much I will miss this platform. Although we are excited for things ahead, I will always keep Vertical Response in my back pocket incase I don't love the new platform as much

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

In retrospect: - I think I should have stressed more demo's / workshopping with the Optimizely team at the start. I felt too confident during demo stages, and when came time to actually start, I was a bit lost. (The answer is likely I should have had them on-hand for our first install.. they offered but I thought I was OK.) - Really getting an understanding / asking them prior to install of how to make it really work for checkout pages / one that uses dynamic content or user interaction to determine what the UI does. Could have saved some time by addressing this at the beginning, as some things we needed to create on our site for Optimizely to "use" as a trigger for the variation test. - Having a number of planned/hoped-for tests already in-hand before working with Optimizely team. Sharing those thoughts with them would likely have started conversations on additional things we needed to do to make them work (rather than figuring that out during the actual builds). Since I had development time available, I could have added more things to the baseline installation since my developers were already "looking under the hood" of the site.

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.

In addition to using Vertical Response personally I also manage email marketing for clients that already use Mailchimp, Robly and Constant Contact. While most of these platforms all offer similar features I choose Vertical Response first if the client does not have a platform in place.

  • I have had nothing but positive impacts from using Constant Contact.
