AWS SES is the cheapest email sending service at scale — $0.10 per 1,000 emails with no per-month base fee. At 100K emails/month, SES costs ~$10 vs SendGrid's $90 or Postmark's $105. The trade-off: SES requires significant setup (sandbox exit, SNS configuration, bounce/complaint handling), has no visual tools, and offers minimal support. Best for technical teams sending high volume where cost optimization matters most.
AWS SES Review 2026: The Cheapest Email at Scale
The Cost Leader
AWS SES pricing is simple: $0.10 per 1,000 emails. No monthly minimum. No per-contact charges. No tier pricing. Just volume.
| Volume/Month | AWS SES Cost | SendGrid Pro | Mailgun Scale | Postmark |
|---|---|---|---|---|
| 10,000 | $1 | $89.95 | $90 | $15 |
| 50,000 | $5 | $89.95 | $90 | $55 |
| 100,000 | $10 | $89.95+ | $90+ | $105 |
| 500,000 | $50 | $249+ | $275 | $525+ |
| 1,000,000 | $100 | Custom | Custom | $850 |
Additional costs:
- Dedicated IP: $24.95/month per IP
- Attachments: $0.12 per GB
- Inbound email: $0.10 per 1,000 emails
Strengths
Cost at scale. Unmatched. The savings compound with volume. At 500K/month, you save $200-475/month vs competitors. That's $2,400-5,700/year.
AWS ecosystem. Native integration with Lambda, SNS, SQS, CloudWatch, S3. Build sophisticated email processing pipelines entirely within AWS.
Scalability. SES scales to millions of emails. No volume caps, no negotiation needed. Request a sending quota increase and it's done.
Dedicated IPs. $24.95/month per IP — cheaper than any competitor. SES also offers managed dedicated IPs that auto-warm following a proper IP warming schedule.
Infrastructure quality. This is Amazon's email infrastructure. The same systems handling Amazon.com's transactional email.
Weaknesses
Setup complexity. The most complex setup of any email service. Sandbox exit, IAM credentials, SNS topics, CloudWatch alarms, feedback loop processing — all manual.
No visual tools. No email builder. No campaign management. No contact lists. No analytics dashboard (beyond CloudWatch metrics). SES is pure infrastructure.
Support. Basic support is free but minimal. Developer support starts at $29/month. Business support at $100/month. Actual human help costs extra.
Sandbox friction. Production access isn't guaranteed. AWS reviews your request and may deny it if your use case isn't well-described. Some accounts wait days for approval.
Self-managed reputation. SES monitors your bounce and complaint rates. If you exceed thresholds (10% bounce, 0.5% complaint), SES suspends your account automatically. No warning, no grace period.
Who Should Use SES
Ideal for:
- High-volume senders (100K+/month) where cost optimization is significant
- Technical teams comfortable with AWS
- SaaS products already on AWS infrastructure
- Application email where you need API integration, not marketing tools
- GoHighLevel agencies at scale (cheapest SMTP option)
Not ideal for:
- Small senders (under 50K/month — savings don't justify complexity)
- Non-technical teams (too much manual configuration)
- Anyone who needs marketing tools (no builder, no campaigns)
- Teams without AWS experience (learning curve is steep)
For detailed comparisons, see SendGrid vs AWS SES, Mailgun vs AWS SES, and Resend vs AWS SES.
Practitioner note: SES is the right answer for cost-conscious high-volume senders who have the technical chops. For a full overview of transactional options, see our best transactional email service guide. I configure SES for clients sending 200K+ monthly where the $200-400/month savings over Mailgun or SendGrid adds up to real money. Below 50K/month, the setup complexity isn't worth the $30-80 monthly savings.
Practitioner note: The auto-suspension on high bounce rates catches people off guard. SES will pause your sending without notice if bounce rate exceeds 10%. Set up CloudWatch alarms at 5% bounce rate to give yourself a warning buffer. And validate your list before every import.
If you want SES configured with proper monitoring, bounce handling, and authentication, schedule a consultation — I handle the AWS complexity so you get the cost savings without the headaches.

Frequently Asked Questions
How cheap is AWS SES really?
At 100K emails/month: ~$10. At 500K: ~$50. At 1M: ~$100. Plus $24.95/month per dedicated IP. Compare to Mailgun at $90-275 or SendGrid at $90-249+ for the same volumes. SES is 5-10x cheaper at every tier.
Is AWS SES hard to set up?
Harder than any managed ESP. You need: AWS account, SES configuration, domain verification, sandbox exit request (24-48 hour approval), SMTP credential creation via IAM, SNS topics for bounce/complaint handling, and CloudWatch for monitoring. Budget 4-8 hours for initial setup.
Does AWS SES have good deliverability?
Yes, when properly configured. SES supports dedicated IPs, custom authentication, and feedback loop processing. The infrastructure is the same Amazon uses for its own email. But you're responsible for reputation management — SES gives you tools, not hand-holding.
What is SES sandbox mode?
New SES accounts start in sandbox: you can only send to verified email addresses. To send to anyone, submit a production access request through AWS Support. Include: your use case, expected volume, bounce/complaint handling plan, and compliance measures. Approval takes 24-48 hours.
Should I use SES or SendGrid?
SES if: cost is primary, you have AWS expertise, you're sending 100K+/month, you don't need marketing tools. SendGrid if: you need a visual email builder, want simpler setup, need marketing campaigns, or don't have AWS experience.
