# SendPit

> SendPit is an SMTP sandbox for email testing during development. It captures emails sent from your application before they reach real users, allowing developers and QA teams to inspect HTML rendering, headers, attachments, and links in a safe environment.

## What SendPit Does

SendPit provides SMTP credentials that developers configure in staging and development environments. When applications send emails to SendPit's SMTP server, emails are captured and stored — never delivered to real inboxes. Teams then view, inspect, and debug emails through SendPit's web interface.

Setup takes under two minutes:

1. Create a mailbox in the dashboard to get SMTP credentials
2. Point your application's SMTP settings to smtp.sendpit.com
3. Send emails normally — they appear in SendPit's inbox instead of reaching real recipients

No SDKs, no code changes, no vendor lock-in. Standard SMTP works with every language and framework.

## Key Features

- SMTP capture with STARTTLS encryption (ports 1025, 587, 2525)
- HTML email rendering preview
- Raw header and MIME inspection
- Attachment viewing and download
- Team collaboration with shared mailboxes
- Organization-level multi-tenancy with role-based access
- Webhooks for CI/CD automation (Pro plans)
- Smart rules for automatic email labeling (Pro plans)
- Shareable email links for non-technical stakeholders (Pro plans)
- Email forwarding (Pro plans)

- Not a log viewer — renders and inspects emails with full HTML preview
- Not self-hostable — SaaS only (for self-hosted alternatives, see MailHog or Mailpit)
