If you are evaluating Amazon SES and SendGrid for email marketing, you are comparing two different layers of the email stack. The answer depends on which layer you actually need.
Amazon SES is delivery infrastructure. It accepts email and delivers it. SendGrid is a platform that includes delivery infrastructure plus a marketing interface, subscriber management, and analytics. That is not a subtle difference -- it changes what you are buying and what you are responsible for.
What Amazon SES actually is
Amazon SES is an AWS service that accepts email via SMTP or API and delivers it. What it does not include: subscriber list management, campaign scheduling, a visual email builder, marketing automation, unsubscribe handling, engagement analytics, or any front-end interface. You get delivery, bounce and complaint notifications via SNS, and sending statistics via CloudWatch.
Getting SES working correctly requires meaningful setup: exiting the sandbox, configuring SPF, DKIM, and DMARC on your sending domains, setting up SNS topics for bounce and complaint feedback, and deciding whether to use shared or dedicated IPs. None of this is particularly difficult for a developer, but it is non-trivial and requires ongoing attention.
The pricing is attractive -- around $0.10 per 1,000 emails. At volume, that is substantially cheaper than any bundled platform. The trade-off is that SES is infrastructure, not a product you use directly for marketing.
What SendGrid actually is
SendGrid is a complete email platform. It includes delivery infrastructure plus a marketing interface, list and subscriber management, campaign builder, automation workflows, and analytics. You can use it for marketing email through Marketing Campaigns or for transactional email through their API.
That abstraction is valuable for teams that want to focus on email marketing rather than email infrastructure. It is less valuable for teams already invested in AWS, who want ownership of their sending reputation, or who are sending at volumes where per-contact pricing becomes significant.
The honest comparison
| Capability | Amazon SES | SendGrid |
|---|---|---|
| Message delivery | Core function | Core function |
| Subscriber list management | Not included | Included |
| Campaign builder | Not included | Included |
| Marketing automation | Not included | Included (basic) |
| Unsubscribe handling | Must build yourself | Automatic |
| Bounce suppression | Via SNS -- must implement | Automatic |
| Dedicated IPs | Available add-on | Available add-on |
| Infrastructure ownership | Your AWS account | SendGrid's infrastructure |
| AWS ecosystem integration | Native | Via API only |
| Pricing model | Per email (~$0.10/1k) | Per contact + volume tier |
| Setup complexity | Moderate -- dev required | Low -- self-serve UI |
Deliverability: what actually matters
Both services can deliver email reliably when configured correctly. The deliverability differences that matter in practice are not about which service you use -- they are about how your sending program is set up and managed.
Authentication moves the needle. SPF, DKIM, and DMARC alignment determine whether major inbox providers trust your mail. Both SES and SendGrid support full authentication on custom domains. The difference is who configures it.
Bounce and complaint handling is critical. Gmail, Yahoo, and Microsoft apply bulk sender requirements including keeping complaint rates below 0.1% and bounce rates below 2%. Both services expose this data -- but with SES you are responsible for building the suppression logic yourself unless you put a platform on top.
Reputation travels with your domain, not your IP. Gmail and other major providers have shifted significant weight toward domain reputation over IP reputation. Your sending domain is increasingly the thing that matters. This means the provider underneath matters less than the practices on top of it.
When SES makes more sense
SES is the better infrastructure choice when:
- You are already running infrastructure on AWS
- You need full ownership of your sending reputation and IPs
- You send at volume where per-contact pricing is significant
- You have a platform already handling the marketing layer
- You want portability -- your SES account and reputation stay yours
SendGrid is the better choice when:
- You want a single vendor for delivery and marketing UI
- You do not have AWS infrastructure already in place
- Your volume is low enough that per-contact pricing is acceptable
- Your team is non-technical and needs a fully managed interface
The case for SES with a platform on top
A pattern that works well for serious sending programs is using Amazon SES as the delivery layer with a dedicated email marketing platform above it. You keep the cost efficiency and infrastructure ownership of SES, while the platform handles the things SES does not: subscriber management, campaign scheduling, automation, unsubscribe processing, bounce suppression, and analytics.
This is the model AledaMail supports. Your SES account -- including your sending domains, dedicated IPs if you have them, and accumulated sender reputation -- stays under your control. If you ever move platforms, you take your reputation with you.
The honest answer
For a sending program that is established, has meaningful volume, and values infrastructure ownership, Amazon SES with a platform on top is almost always the better long-term decision. The cost efficiency at volume is real, and the portability is genuinely valuable.
For a new sending program that does not have AWS infrastructure and needs the lowest possible setup friction, SendGrid is a legitimate starting point. You can migrate later if volume and cost become drivers.
The decision is rarely about deliverability or features at a technical level. It is about operational model, infrastructure ownership, and where your volume and budget puts the cost curve.
Use Amazon SES with a proper marketing platform.
