Terrible Experience **Rating:** 0.0/5.0 stars **Reviewed by:** Nathan C. | Small-Business (50 or fewer emp.) **Reviewed Date:** October 30, 2024 **What do you like best about Epsilon Services?** Customized list modeling, availability of lists **What do you dislike about Epsilon Services?** After jumping through many hoops to launch our latest direct mail campaign, we were continually strung along until finally, Epsilon stated they would not be able to deliver the list. This delayed our campaign by over 4 weeks. This company is not the high quality performer it was in the past. **Recommendations to others considering Epsilon Services:** I found out later that Epsilon is a resller, not a top tier list broker. You would be better served going higher tier with a company like Data Axle or some other provider. Epsilon is simply a middle man for other companies list data **What problems is Epsilon Services solving and how is that benefiting you?** We were using Epsilon for direct mail and some online marketing. ### 2.

Archaic system, not very adaptable to 2020 marketing need for speed **Rating:** 0.5/5.0 stars **Reviewed by:** Verified User in Sports | Mid-Market (51-1000 emp.) **Reviewed Date:** January 16, 2020 **Describe the project or task Epsilon Services helped with:** I use Epsilon Harmony to orchestrate all of my business's email marketing communications (1.7M audience). Despite our large audience, we are a lean digital marketing team and I am the only person running day-to-day operations in the platform. We use an on-prem Data Warehouse that stores our purchase data and CRM which does not integrate with Epsilon. We have an ongoing contract with them including monthly check-in calls to talk strategy, optimization, and innovations we can implement into our marketing strategy. **What do you like best about Epsilon Services?** The platform has a nice report highlighting your engaged, high-risk, not-active, and never emailed contacts as well as a report for when your emails are getting opened (time of day and days of the week). Aside from that, I have to build pretty much all of our other reports in Excel to get accurate measurements around each of our segments over different time-periods. Their account management team is pretty innovative, especially Marlene and Polina. They've come up with many creative solutions to work around the platform's weaknesses and are pretty knowledgeable about the product. We had some communication friction when getting started, but since setting up regular check-in calls the process and experience has drastically improved. **What do you dislike about Epsilon Services?** Taking into account the load times and the multi-step processes required for a simple request (exporting all contacts from a segment, creating dynamic content, running segment counts, and saving/deploying emails), I waste a lot of my time waiting on page loads and count updates. Few to no systems have integrations with Epsilon so you will need your own developer to integrate data feeds into the system, otherwise you need to devote 10-30 minutes to manipulate the CSV data from your data feed to correspond to Epsilon's finicky importing needs. The software has the ability to do advanced projects if you have the time to set them up and the development resources to set the appropriate API integrations to use as a trigger. The biggest frustration is the lack of control you have over your business and preference pages. All Epsilon Harmony forms (including your sign-up form and preference center) must be hosted on the Epsilon server and you will not have any ability to make updates as a user. Instead, you will need to pay upwards of $2,000 to make minor changes to this page, based on their time and scope estimates. Even with these scopes, it took over 12 weeks from request to completion to get a form field removed from our form. Heaven forbid we wanted to update the form fonts, colors, and images to better match our branding we likely would have been quoted well over $20,000 for the update. While it may be the cheapest option for an ESP of its caliber, you make up those costs in ad-hoc projects or software to support a multi-channel marketing program. If you run your lead-collection through several different sources that are not linking to the Epsilon sign-up or Manage Preferences form, you'll have a challenge adhering to subscriber preferences if you have several preference channels (i.e. Newsletter, Sales/Offers, Special Events, etc.) As they do not keep records of when someone opted out to a specific channel. **Recommendations to others considering Epsilon Services:** This platform is best for businesses that have programming and developer resources to help with API integrations in addition to those familiar with email code and best practices. I do not recommend using if one person needs to execute all campaigns from start to finish in addition to reporting, database management, etc. If you run your business and data through one site with only a couple of partners, you won't face as many challenges. We have data and information and subscribers coming in from 15 different partners and do not have the developer manpower to write the appropriate APIs needed for all of this data to sync together so we have to manually do it in Excel and import into Epsilon which creates a time inefficiency and leaves room for errors. It can take upwards of 30 minutes just to format the data into the format Epsilon needs in order to accept it. **What problems is Epsilon Services solving and how is that benefiting you?** Our POCs at Epsilon are really helpful and strive to help solve our problems in creative ways, but it seems they are basically trying to bandaid the platform rather than update the platform to adapt to today's digital communications capabilities and expectations. Some interesting solutions they've mentioned include automating our regular newsletter using an RSS feed from our website, reactivation campaign to re-engage lapsed subscribers and clean out deadweight contacts, and consulting around setting up email drip sequences around our giveaways and partner data collection. ### 4.
