What do you like best?
PeopleImport does what Salesforce eliminated from Data Import Wizard in the 2016 Winter Release: the ability to upload lists of Leads and Contacts and bucket them together into a Campaign, all in one fell swoop. But it goes beyond those Salesforce basics to do advanced functions where you can choose the Salesforce fields to update, ignore, or even merge, and provides advanced matching functions, like matching to nicknames, fuzzy match, and even AUDIBLE match where words/names that sounds similar will match. It allows you to Alpha clean data also in one fell swoop, ignore rows...WOW. It is very powerful. You can even fix errors in a Review stage before the final upload (at least to a small degree).
What do you dislike?
The interface looks incredibly dated - and there are many buttons to click and choose from, many that do exactly the same thing but are just repeated on the various screens. Clunky is the best word for it - or like those children's toys that have a ton of levers and buttons and some of them produce sounds and lights, different buttons and levers oddly product the same sounds and lights, and some buttons don't do anything discernible. There are many steps and the end goal can be accomplished in several ways. Often you're not even sure what you're looking at when you're looking at the Match Results and what the tool is telling you you're about to. Error log files are not usable as is - they're not fixable in Excel and then re-importable. The tool exports a bunch of code that is mostly unusable, so it's best to fix errors as you Review them in the tool. It's not a tool you can jump into and just figure out - you have to watch their YouTube videos, the only form of documentation available. The videos do not cover all the use cases you may have...so you have to just guess or reach out to the company and I've found their help personnel to be inadequate. You can't purchase the software without having to email or talk to a rep, you are invoiced with an invoice you have to print out...unbelievable in the world of today...but perhaps just fine for 1998.
Recommendations to others considering the product
Be prepared for a steep learning curve in the software, and multiple failed imports if your data is ever-so-slightly not in the right format as your Salesforce instance. Be prepared for time spent in parsing through Error logs to try to figure out what went wrong with your imports, and eventually just throwing large logs away since they're too large to try and sift through. Be prepared for a painful old-school purchasing process, minimal support - and a clunky interface that takes time to wade through. (Hint: Save your Scenarios and field Mappings to expedite crawling through the PeopleImport interface!)
