Amazon SES
Amazon SES uses simple pay-as-you-go pricing with no hidden fees or contracts. You only pay for what you use, making it affordable for any business size.
Free Tier: New AWS customers get 3,000 message charges free monthly for the first 12 months. This covers sending, receiving, or using Virtual Deliverability Manager features. Each sent or received email counts as one message charge.
Standard Pricing: After the free tier, outbound emails cost $0.10 per 1,000 emails sent, plus $0.12 per GB for attachments. Inbound emails cost $0.10 per 1,000 emails received, plus $0.09 per 1,000 chunks processed.
Add-on Features: Dedicated IPs start at $24.95 monthly per address. Virtual Deliverability Manager costs $0.07 per 1,000 emails for volumes under 10 million. Mail Manager open ingress endpoints cost $50 monthly, with email processing at $0.15 per 1,000 emails.
DoubleZero
DoubleZero offers two pricing options that stand out from typical subscription services.
The Free Version is completely open source and available at no cost. You can download the code, host it yourself, and use all core features including transactional emails, monitoring dashboard, multi-recipient tracking, SMTP endpoint, and REST API access. Your only costs are AWS SES fees, which are extremely low at around $0.10 per thousand emails.
The Pro Version costs $175 as a one-time purchase. This is not a monthly subscription. You buy it once and own it forever. Pro adds powerful features including a WYSIWYG email editor, contact management system, email lists, broadcast campaigns, team collaboration tools, activity feed, and automation workflows.
Both versions require you to provide your own AWS account and hosting, giving you complete control and keeping ongoing costs minimal.
