# The Customer Communications Stack

> A landscape look at six companies that quietly run the customer communications and document automation stack. Optimove decides who to message and when, Twilio and Lob handle delivery over text and physical mail, and Newgen, Windward, and Experlogix turn structured data into the statements, contracts, and quotes that land in your inbox and mailbox. Different categories on the analyst charts, one shared job: convert a database record into a message a person reads.

## Achievements

- Twilio turned messaging and voice into a few lines of code, becoming default infrastructure for app-to-person communication.
- Lob proved physical direct mail could be programmable and measurable, wrapping print and postal delivery in an API.
- Optimove raised $75M to scale AI-driven CRM journey orchestration for consumer brands.
- Newgen Software grew into a publicly traded (NSE: NEWGEN) digital transformation platform used by banks, insurers, and governments.
- Windward Studios built document generation on top of Microsoft Office templates, serving 2,000+ customers before its Apryse acquisition.
- Experlogix pairs CPQ (configure, price, quote) with document automation to generate accurate quotes and contracts at the point of sale.

## Latest updates

- **2023-01** — Windward Core rebranded as Fluent by Apryse after joining the Apryse family.
- **2025-06** — Lob published research arguing direct mail still breaks through digital noise for marketers.
