What is a email & messaging cybersecurity company?
A firm whose primary offering sits in email & messaging. This index lists companies, not SKUs — products live on the company profile.
Is the order paid?
No. Companies are alphabetical by default. You can sort by team size or date added. Promoted shelves are labeled and separate.
How do I get listed in Email & messaging?
Submit a company. We review before anything is public. Paid plans buy a labeled shelf, not a silent bump in this list.
Why is this a Market focus rather than a tool category?
Buyers shortlist firms. Tools change names; the company is the contract.
