Strengths and weaknesses
Amazon SES- +Lowest-in-class price at $0.10 per 1,000 emails with no monthly platform fee or minimum commitment
- +Scales to millions of emails effortlessly on AWS's proven sending infrastructure
- +Deep native integration with Lambda, S3, SNS, SQS, CloudWatch, and IAM
- –No built-in dashboard for opens/clicks/bounces/complaints, you must wire up SNS/Lambda yourself
- –Sandbox mode (200/day, verified recipients only) plus a manual production-access request before real sending
- –No templating UI, campaign management, or marketing automation, purely sending infrastructure
- +Strong, industry-respected deliverability via the Adaptive Email Network with real-time adaptive delivery and automated IP warmup
- +Built for very high volume/scale (customers collectively send ~20B+ emails per month)
- +Mature REST API plus SMTP relay, with official SDKs for Node, Python, PHP, Go, and Java
- –Generous free tier (formerly 100k emails/month) has been discontinued; paid plans now start at $20/month
- –Acquisition by MessageBird/Bird has folded the product into a larger CRM platform, creating branding/strategy uncertainty (some sites mark it 'discontinued')
- –Recurring reports of abrupt account suspensions, sometimes without clear explanation
