Lob review

Lob is the infrastructure pick on this list: an API-first platform for postcards, letters and checks that also offers a no-code design suite and address verification. Plans are sized by annual mail volume. Developer is free for up to 6,000 mailings and 1 user, Startup costs from $260 per month for up to 75,000 mailings and 3 users, Growth from $550 per month for up to 150,000 mailings and 5 users, and Enterprise is custom for larger programs. Print and postage are billed on top, starting at $0.905 per postcard on Developer and $0.615 on Growth. Every plan includes in-transit tracking and an analytics dashboard, while no-code integrations start at Startup and custom envelopes, specialty formats and HIPAA support are Enterprise only. Marketers who do not have engineering help will find Postalytics or Thanks.io quicker to start with, but teams sending tens of thousands of pieces a month get volume pricing and tooling few rivals match.
