Pros & Cons from Real Users Pros Very easy to use and simple to generate emails. Uploading lists and organizing is flawless. It's almost perfect! The calendar view aids in tracking deployments by date, promoting collaborative work among team members. The message editor is user-friendly, and custom field-based subscriber search is a valuable feature. Deployment-specific message metrics are neatly organized and offer exportable one-page reports. Additionally, data/list exports are significantly faster compared to our previous platform, taking less than a minute, even for large exports. The reporting options on Critical Impact are incredible! The email editor is very user friendly and allows you to create custom emails or customize well done templates. This email marketing platform is very easy to use and includes a plethora of features that make my job as an editor much easier. This is an exceptional drag and drop platform that allows myself to be creative because of the advanced software in place. - Critical Impact is an extremely easy to use marketing platform, that allows our customers to manage and execute on their marketing plan. - Critical Impact offers fantastic support to us when troubleshooting through new workflows like SMS, and giving feedback in helping us improve how we utilize the software as a company. Cons Uploading images takes forever and sometimes dynamic lists take very long to generate. I believe you need a better server. Until this point, I have not faced any issues with Critical Impact. It performs well in every aspect of email marketing. I honestly do not have any major cons, Critical Impact has been easy to learn with an informative help center/ customer service when I do have an issue Occasionally, Critical Impact will have issues loading from page to page which can be frustrating, but Critical Impact's customer service team is very responsive and will help work through any issues you have. - The SMS registration process initially was a very long and drawn out process, with little to no insight into whether we were going to be able to offer this product to our customers. We eventually put together a workflow that worked, but it took months to get to that point.
