What does the software or service do well? Imagine that your home and work emails, your LinkedIn contacts, and your Twitter connections shared a single database. Now imagine that database constantly checks the data to ensure that email addresses and links still work. And imagine that the database was available on all of your devices. That's the promise of Contacts+ (contacts plus), great web software that used to be known as Full Contact. The software solves a huge time suck for anyone with lots of contacts: how to keep everything updated and connected on all your devices? Before I began using Contacts+, I would often email someone and learn that they had moved on from the company. Or I would want to write someone that I knew personally but in a business context and have to log in and and out of different email accounts. Contacts+ allows users to sync up to 5 accounts and provides weekly reports and suggestions through its "assistant feature". You can accept all the assistant's suggestions or do as I do and scan it for a quick overview of your contacts and their movements. There is even a function that tells you who is celebrating birthdays next week.
What does the software or service not do well? When I first began using Contacts+, the service integrated with more social media platforms. Soon, Facebook disappeared. LinkedIn is available as a manual sync today, which is great, but a little more work. There are also still Twitter and Foursquare integrations. The Facebook issue isn't the company's fault, but has to do with Facebook's changing permissions over time. And there is a neat Chrome extension that allows you to tag a Facebook user and associate them with your account.
What do you wish you had known about the software or service before using? Contacts+ has almost always exceeded my expectations, and I've been a paying customer for more than 5 1/2 years. The company has a big focus on business card scanning and transcription into the database that seem people to really like. I've used the function, but thankfully don't get many business cards these days. There is also a nice sidebar for Gmail that allows you to view the most up-to-date contact information of the person you're interacting with in Gmail.
Have you used a competitor to the software or service? If so, how does it compare? I've used all sorts of contact managers from Contactually and Cloze to Rapportive (now Sales Navigator) to Zoho. Nothing has been able to match all of the functions available at Contacts+ for the low price point. Since then, I've done the one thing that ensure retention. I've stopped actively looking at competitors. The service met my needs years ago and saved me oodles of time while being darn near 100% reliable. Why should I look to replace it?
