# Custom Email Domain

> Customize the emails that are sent by the Tight API to match your domain

## Overview

Tight can send emails on your behalf (e.g. if your user wants to email a financial report to their advisor) from any domain.

## Domain Configuration (SMTP)

Tight uses SMTP to send emails from your domain. Simply, provide your:

1. SMTP Username
2. SMTP Password
3. SMTP Host URL (e.g., smtp.mandrillapp.com for Mandrill)
4. SMTP Port (generally 465 for SSL or 587 for TLS)
5. Preferred address for the available email types:
   1. Reports: e.g. [reports@yourcompany.com](mailto:reports@yourcompany.com)
   2. Invoices: e.g. [invoices@yourcompany.com](mailto:invoices@yourcompany.com)
