Transmit

Overview

Most email services pool senders on shared IPs, so one bad actor can drag your domain into spam. Transmit eliminates that risk with truly isolated, dedicated sending infrastructure at the cloud level—your reputation stays yours. You can operate in Managed mode or Bring Your Own Keys (BYOK) with AWS SES, and switch between them without changing a line of code.

Key Features

• Isolated sending infrastructure: dedicated environment per customer to safeguard reputation and deliverability.
• Managed mode: go live in minutes with automatic domain warmup (1.5x/day ramp, auto-pause on high bounces), one-click DKIM/SPF/DMARC, and built-in validation to block invalid and disposable emails.
• BYOK with AWS SES: keep low SES pricing while adding campaigns, contacts, real-time analytics, automated warmup, inbound routing, and searchable message logs.
• Secure connections: IAM Role assumption using temporary STS tokens, or AES-256-GCM encrypted access keys stored at rest and decrypted only in memory.
• Results-driven: customers report 99.2% inbox placement across providers.
• Transparent pricing: Managed plans from $2/month; BYOK totals about $249 at 1M emails vs. $650+ on typical platforms.
