    Chose Litmus from Validity
    I’ve used Sailthru’s testing feature in the past, however it was always in conjunction with Litmus as they have features that Sailthru doesn’t , such as reviewing inline, and a design library that was used as a repository.

    I think CheetahMail, being one of the main ESPs in the market, is a quality choice. However, I would suggest that it's really only valuable for a bit larger of an organization, generally having staff of 100+ and revenues in tens of millions -- this is mainly to justify the amount of investment required, so may be cost-prohibitive to some. You also need to make sure that you understand the entire "level of support" you will gain through your specific contract.... the key is understanding what types of resources are within your organization (who's doing the coding? who comes up with the next campaign? What's the overall strategy?) Depending on these questions and resources, may help determine your final needs from a services point of view. CheetahMail can provide a wealth of various services specific to needs (and changes over time as your business changes), but a clear understanding of what you have before you bring them on will really help getting up and running quickly. Also be sure to truly understand the costs for the initial integrations, setups, IP senders, etc.

    Proofing your emails is necessary. This is a tool that allows you to see how your email not only renders on multiple devices but how it performs. Some email building platforms will tell you their drag and drop templates are ready to go, however they stop short of analyzing accessibility, checking links, load speed among other things. I've also experienced drag and drop template issues as new email clients are released. Litmus provides peace of mind that you did your due diligence on crafting your email. While Litmus does provide some reporting you will not see every typical analytic an email report offers. However, you can use your Litmus data to enhance your email reports which in turn creates a robust view of email performance.

    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

    • Internal management - This is a great web-based tool that allows our users to see what emails go to whom.
    • Organization - Many layers of organization for templates since there are many types of remarketing emails that we send out.
    • Historical Records - CheetahMail sends us the raw text files of all email actions so we can upload them to our database.

    • We haven’t explored the personalization features in depth yet, aside from using the Add-to-Calendar option, but we're excited to dig in further. Tools like live polls offer an easy way to boost engagement in our product marketing emails, and we see a lot of potential in using these templates to enhance personalization moving forward.
    • Litmus’ continuing education resources have been really helpful. I recently read an article on email deliverability that offered practical insights my team can apply moving forward. I especially appreciate how Litmus uses real examples and stats from the brands they work with—it makes the content feel actionable and relevant.
    • Online Training.

    • 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

    • The organization of CheetahMail could at times be better, as you create more and more mailings, they just pile up in a long list. It would be useful to be able to create folders to store specific mailings in. (ex. editorial, newsletters, marketing, etc.)

    • I've not seen many limitations but I have noticed that sometimes emails sent from our CRM take too long to land in Litmus, or sometimes don't land at all.
    • As a beginner it was quite difficult for me to make my way around the platform - I thought "Create new" CTA was actually creating something new, maybe "Import from CRM" would have been more understandable. There were a few others but I remember this one.
    • In the Emails section, whenever I hover over an email, I want to be able to copy the subject line instead of getting the different CTAs appear intrusively (Summary, Builder, Previews & QA, Proof, Analytics, Monitor) - maybe these could appear on the bottom of the textbox, instead of them being imposed on top?

    • 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.

    As I have begun exploring competitors, I've come to realize that every competitor offers so much more functionality and integration than CheetahMail does. When we first signed our contract, CheetahMail was much more innovative and at the forefront of email. Since being bought out by Experian, we've seen a huge decline in service and innovation. They have laid off much of their staff and moved their account representatives to Costa Rica. They also heavily rely on on third parties which you will have to pay large amounts of money for while other Email Service Providers have integrated new technologies into their platform. You will get more for your money going to a different email service such as Responsys, Silverpop, Listrak and the like,

    It's one the best tools that we've found for this type of tool but we would like some additional features like spell check so if there's a platform that features that with everything else Litmus has, then we'd potentially look to move over to that platform instead.

    Litmus has integrations that make the software an integrated part of my work every day. Being able to test right within my email builder is just brilliant.

    As with all technology, there are inevitably use-cases where you are unable to get to your original goal without some good old-fashioned experimenting. Some situations will (and are) more urgent which complicates an effective integration of a new process or a new team using an existing process but the "issues" are regularly resolved by re-starting the process specific to when Litmus is introduced to a project. If it doesn't come out the way you're anticipating, run it again and verify there is an issue before declaring all is lost

    Absolutely fantastic support. It runs circles around the competition. They regularly reach out and chat, even if it's just to see if there's any issues we need to discuss. They clearly want the business and don't forget you once you sign the contract which is an issue with other similar services.

    I didn’t really personally participate much in the implementation of Litmus, but from what I observed during the process, it was a smooth process with minimal disruptions. The team was able to get up and running quickly, and the platform’s user-friendly interface made onboarding fairly easy for everyone involved from the start.

    I believe Cheetah DMS is a bit more complete and a lot more complex to use than Mailchimp. Mailchimp was born as a mail marketing service while Cheetah has always worked across the whole online advertising spectrum making it a better solution for clients that need a certain level of service and sophistication.

    This is not applicable to my role as I have used Litmus to test emails since I have started. Because of the ease of use, timeliness, consistent quality, and affordability that Litmus offers, I haven't found the need to look at similar products or organizations. If all of these features continue to stay strong, I don't plan on changing providers

    • Our efficiency has decreased with CheetaMail actually. Too many service calls to find out why something isn't working as expected, account setup questions, issues with PiP, takes too long to get a simple form built, customer service response time, etc...
    • Reporting is not very streamlined. This has caused us to take our reporting offline and use a method with better visibility.

    • We often send out campaigns out to thousands of members, and Litmus gives us the assurance and peace of mind that everything is working as it should before it gets sent out.
    • Decreases the number of email review cycles we go through.
