    Ceros is fantastic for companies who can afford it. It's not ideal for startups who don't have the budget for it. If your company or agency is interested in creating interactive content, but you don't have the skill sets in-house to develop or code them properly, Ceros is for you

    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.

    If you have Marketo or Pardot and have emails that might be somewhat simple to slightly complex, without the budget for a developer, Knak is the right solution for you. If you have complex emails that require a lot of code or customization and have the in-house resources, Knak might not be the perfect solution

    Pros
    Ceros
    • Easy to use and adopt user interface. If you know basic Photoshop, you can use this.
    • Encouraging roadmap - the product has gotten better every year. The company obviously listens to client feedback.
    • Smart, dedicated client team - always checking in, comes with new ideas, generally nice people. We always love our meetings with them!

    • 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.

    • 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.

    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.

    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

    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

    Our CSMs have always been 100% and their support team typically responds within an hour or two. Their design/build team also worked with us on perfecting several experiences and are always mindful of how a project is going. One of their designers didn't really understand one of our requests and the project took more rounds of revisions than in previous projects, but they rectified the issue and the project came out well in the end. That outcome probably only happened in the time it did due to our CSM consistently checking in and getting feedback throughout the project - unfortunately, not something that happens enough with all our partners.

    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.

    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

    Ceros takes what would be difficult to accomplish in the Adobe suite of products and makes it easy. When it comes to user experience, user interface and customization options, Ceros is a much better alternative than Adobe. However, Adobe is the trusted name and some may be more comfortable with Adobe products

    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.

    • 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.
