# Communications

Peach's communications system is how your platform talks to borrowers — payment reminders, statement notifications, hardship outreach, regulatory disclosures, and any custom messaging your product needs. It runs across eight channels — Voice, Email, Fax, Text (SMS), Chat, Mail, GUI (in-app), and Document — with a shared template engine that exposes approximately 50 template variables, and supports both transactional sends (one borrower at a time, driven by a loan event) and bulk campaigns (many borrowers at once, driven by a SQL query).

## In this section

- **[Editing Templates](/communications/editing-templates)** — Customize communication templates using the API or the Admin Portal template editor.
- **[Bulk Sender](/communications/bulk-sender)** — Set up and run borrower campaigns with Redash queries and scheduled sends.
