InboxPilot
Send email campaigns from your own SMTP.
InboxPilot connects to any SMTP account. Import contacts, design templates, and send directly. No third-party service, no per-email fees. You keep your data and your deliverability.
Works with any RFC 5321 server

A full campaign toolkit
Four parts, one workflow — from connecting a server to reading back what it accepted.
Bring any SMTP account
Bring any SMTP account — Gmail, Outlook, Hostinger, Amazon SES, or your own server. Credentials are encrypted at rest and never shown again. We build an isolated transport per send, so one user’s SMTP can never bleed into another.
- Encrypted per-user credentials
- SSL (465) and STARTTLS (587)
- Automatic connection test
Import contacts and keep them clean
Upload a CSV and InboxPilot validates every row on the way in — checking columns, normalising addresses, and dropping duplicates. Unsubscribes are held in a per-user suppression list and enforced on every send.
- CSV validation with column mapping
- Automatic de-duplication
- Invalid addresses and unsubscribes filtered
Compose once, throttle the send
Design a template, preview it safely, then send. Sending is throttled per hour so you stay within provider limits, and you can send now or schedule it. Delivery runs in resumable batches — close the tab and it pauses, never corrupts.
- Reusable templates with merge fields
- Per-hour throttling
- Send now or schedule
Reports you can actually trust
See exactly what your SMTP server said for every message — the raw accept or reject response, per recipient. No invented “open rates” you can’t verify. Accepted means the server took it; nothing more is claimed.
- Per-message server responses
- Accepted vs rejected counts
- No fake open or click metrics
Test your SMTP in one click
Before a single campaign goes out, InboxPilot verifies your connection end to end. Connect, authenticate, send a real test, and read back exactly what the server said.
