    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.

    Email Elastic is best suited in cases when we need to send bulk emails and campaigns. It provides features such as scheduling campaigns and automating fast delivery of emails; the trial version also provides many features that can be used by a new user. Email Elastic is less suited for small companies with a smaller number of clients or contacts.

    WhoisXML API
    We use WhoisXML Email Verification API for the additional value it provides to our corporate email security, and we recommend that most organizations do the same. Disposable email services may help protect the privacy of their users, but in the corporate setting, receiving emails from these domains may not be safe. So, aside from flagging emails from domains categorized as spam, we wanted our spam filtering system to be stricter and include disposable email addresses.

    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.

    WhoisXML API
    • WhoisXML Email Verification API obtains its disposable email detection capabilities from a disposable email domain database that monitors most disposable email providers regularly.
    • WhoisXML Email Verification API is compatible with most spam filtering solutions and other email security systems. It is also available as a Splunk application, so compatibility wasn’t an issue for us.

    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.

    • I wish they didn't have such a strict requirement regarding their "opt out" links in emails. I totally understand why they do this, but there are use cases, such as one to one personal emails between individuals, where this is annoying. However, it's something I'm willing to live with for the greater good.

    • We had to avail ourselves of the custom plan because we have a pretty large user base, and each user receives hundreds of emails per day. We were able to come up with a reasonable agreement, in any case.

    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

    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

    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.

    I have not had any issues with Elastic Email that have required reaching out to support, so I can't speak to the quality of their customer support. The help documents were well written and presented, though, and I would imagine that anyone with issues would receive satisfactory assistance in a timely manner.

    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

    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.

    Email elastic is a cost-effective, fast, and reliable platform for sending bulk emails and promoting campaigns, it provides good features even for the new user, while Blaze Verify pricing is a bit high, and a new user would not be able to access all the features. Hence clearly, Elastic email leads the position when compared to Blaze Verify.

    • 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.
