Simple, powerful, and a stellar team.
What do you like best?
The APIs are simple. The business model is very clear and concise: send an API request, things get printed. We've been using Lob for years and have had no issues at all. Uptime and availability have been great. And I can't express enough how happy I am with the team, both support and management.
What do you dislike?
I haven't encountered anything that fits this question. This product does exactly what it says, exactly how they say it does. There's nothing to complain about at all.
Recommendations to others considering the product:
Don't be afraid to reach out to them if you get into a pickle during implementation. The service has grown a bunch since I built our implementation. Use all of the features :)
What problems are you solving with the product? What benefits have you realized?
On-demand API driven printing is the core of my business. It can certainly be done without Lob, but the breadth and depth of the service are beyond any local solutions I've found. From the simple print API to the real-time postal updates and address verification - the whole thing's a dream for me.
