Domain authentication

Generate SPF, DKIM (2048-bit) and DMARC records, then verify them with live DNS lookups before you send.

โœ…

Consent & suppression

Every contact carries opt-in status, source and timestamp. Suppression is automatic and enforced on every send.

๐Ÿ“ง

Graph API & SMTP

Connect Microsoft Graph (OAuth2) or Office 365 SMTP (STARTTLS 587). Secrets are stored server-side and masked.

๐Ÿ”ฅ

Warm-up & throttling

Gradually ramp new domains with a daily-cap schedule and per-domain rate limiting in the sending queue.

๐Ÿšช

One-click unsubscribe

RFC 8058 List-Unsubscribe headers, a working unsubscribe page and automatic suppression โ€” required on every message.

๐Ÿ“Š

Deliverability dashboard

Delivery, bounce, complaint and unsubscribe rates, auth status, warm-up progress and a spam-score checklist.

Simple, transparent pricing

Built for compliance

InboxPilot is designed as a legitimate Email Service Provider. It refuses to send to contacts without recorded consent, blocks templates without an unsubscribe link and physical address, and auto-suppresses hard bounces and spam complaints. Read our Acceptable Use Policy.
