Postmark

Postmark has one focus: getting transactional emails delivered. While others try to do everything, Postmark does one thing exceptionally well—ensuring your important emails reach the inbox.

Key Features:

• Elite Deliverability - Consistently top-rated inbox placement
• Transactional Focus - Built specifically for app-generated email
• Message Streams - Separate transactional and broadcast sending
• Templates - Server-side templates with variables

Why Postmark for transactional:

• Deliverability First - Strict anti-spam policies protect reputation
• Fast Delivery - Average delivery in seconds
• Transparent - See exactly what's happening with every email
• 45-day Retention - Full email history for debugging

Postmark capabilities:

• Inbound Processing - Parse incoming emails
• SMTP & API - Flexible integration options
• Webhooks - Delivery, bounce, and spam notifications
• Analytics - Delivery stats and trends

Postmark is ideal when email deliverability directly impacts your business—password resets, order confirmations, security alerts. The premium pricing reflects the premium deliverability, which is justified when email failures mean lost customers.
