What I like best is how it turns physical mail into something developers can automate like any other API. You can programmatically send postcards, letters, checks, etc., without building the printing, addressing, and mailing infrastructure yourself. Review collected by and hosted on G2.com.

What I like least about Lob is that it isn’t very user-friendly for new users. When I first started using Lob, it took me a while to work through each layer of the interface to find what I was looking for. Review collected by and hosted on G2.com.
