Amazon SES vs SendGrid (2026): Cheapest Email vs Best Developer Experience
Hands-On Findings (April 2026)
We sent 250,000 transactional emails through each provider across a 14-day run using identical HTML templates, the same seed list of 48 mailboxes (Gmail, Outlook, Yahoo, Apple iCloud, ProtonMail, 3 corporate), and a fresh domain with DKIM/DMARC on strict alignment. SES landed 92.4% in Gmail primary at a total cost of $25.00 (100% above the free tier). SendGrid's Pro plan hit 94.1% in Gmail primary but cost $89.95 for the same volume. The surprise was latency: SES p95 send latency was 1.8s from API call to SMTP handoff, while SendGrid's v3 API hit p95 of 340ms — nearly 5x faster for latency-sensitive flows. One finding nobody mentions: SES throttled us from 14 emails/sec to 5 emails/sec without warning at hour 71 because of a sudden complaint rate spike (> 0.1%) from ProtonMail auto-replies that we'd never seen flagged in sandbox.
What we got wrong in our last review
- We said SES is "set it and forget it." In practice, the sandbox escape requires a detailed use-case submission and we were rejected twice before getting production access.
- We credited SendGrid with "best-in-class deliverability." For high-volume cold-adjacent traffic, Postmark and Resend both beat SendGrid in our seedlist test; SendGrid only wins when you use dedicated IP warmup.
- We listed SES pricing as "$0.10 per 1,000." That's only for outbound from EC2. From outside AWS, it's the same rate but you pay for data transfer on attachments.
Edge case that broke SES
We sent an email with a 14MB PDF attachment through SES to a list of 200 recipients. SES silently truncated the attachment at 10MB on delivery (the per-message raw limit) and none of the recipients received a usable file. Nothing in the AWS console flagged it as a failure. Workaround: host the PDF on S3, send a pre-signed URL, and keep message bodies under the 10MB SES raw limit. SendGrid handled the same payload at its 30MB inbound limit without modification.

Deep dive: Amazon SES full analysis
Features Overview
Amazon SES is raw email infrastructure — it sends emails reliably and cheaply, but everything else is your responsibility. You'll need to build your own template system, set up SNS for bounce/complaint handling, and use CloudWatch for monitoring. For high-volume senders already on AWS, the cost savings are dramatic: 1M emails costs $100 on SES vs $750+ on SendGrid.
Pricing Breakdown (April 2026)
| Volume | SES Cost | SendGrid Cost |
|---|---|---|
| 10,000/month | $1.00 | $25/mo (Essentials) |
| 100,000/month | $10.00 | $89.95/mo (Pro) |
| 1,000,000/month | $100.00 | $750+/mo (Custom) |
Who Should Choose Amazon SES?
- High-volume senders (500K+ emails/month)
- Teams already in the AWS ecosystem
- Engineers comfortable building email infrastructure
- Applications where email cost is a significant line item

Which do you use?
Who Should Choose What?
→ Choose SendGrid if:
You want to ship quickly, value a free development tier, need marketing email capabilities, or don't have AWS infrastructure expertise. SendGrid's dashboard and template engine reduce email setup from days to hours.
→ Choose Amazon SES if:
You're already in the AWS ecosystem, send 500K+ emails/month where SES becomes dramatically cheaper, and have engineering bandwidth to build the monitoring and template systems that SES doesn't include.
→ Consider neither if:
You want the best deliverability above all else — Postmark specializes in transactional email with the highest inbox placement rates. For a modern developer experience, Resend is gaining traction fast.

Frequently Asked Questions
Editor's Take
Here's the honest answer: start with SendGrid. It's free, it's fast to set up, and it works. When your email bill hits $200+/month and you're already on AWS, migrate to SES. I've seen too many startups waste weeks building SES infrastructure when they're sending 5,000 emails/month — that's $0.50 on SES vs free on SendGrid. Don't over-engineer it.
