Cost per email comparison and deliverability control differences.
The AWS SES vs SendGrid comparison is one of the most common questions for cold email senders choosing their sending infrastructure. Both are email delivery services, but they differ significantly in pricing, infrastructure control, compliance policies, and the level of abstraction they provide. Understanding the SES vs SendGrid tradeoffs helps you choose the right foundation before you build campaigns on top of it.
Amazon SES is a low level sending service from AWS. It provides raw email delivery at scale. SendGrid (now part of Twilio) is a higher level email platform that includes delivery infrastructure along with additional features like template builders, analytics dashboards, and webhook integrations. Both can send email, but they serve different levels of technical comfort and different budget expectations.
This is where the AWS SES pricing vs SendGrid gap is most visible. Amazon SES charges $0.10 per 1,000 emails with no monthly minimums. Sending 100,000 emails per month costs $10. SendGrid offers a free tier for up to 100 emails per day, but their paid plans start higher and scale with volume and features. At higher volumes, the cost difference between the two platforms becomes substantial. For cold email senders who send tens of thousands of emails monthly, SES is dramatically cheaper.
SendGrid's pricing includes features that SES does not offer natively, like analytics dashboards, template management, and deliverability insights. If you value those features and do not want to build or buy them separately, the higher SendGrid price includes that functionality. If you plan to use a separate cold email tool for campaign management anyway, those extra features matter less.
| Factor | AWS SES | SendGrid |
|---|---|---|
| Pricing | $0.10 per 1,000 emails | Free tier plus paid plans scaling with volume |
| Infrastructure | Dedicated to your AWS account | Check their site for shared vs dedicated IP options |
| Cold email policy | Allowed with compliance requirements | Check their acceptable use policy |
| Setup complexity | Technical (DNS, IAM, SMTP credentials) | Moderate (API key, DNS verification) |
| Built in analytics | Basic (via CloudWatch and SNS) | Detailed dashboard included |
| Campaign management | No, sending only | Basic marketing campaigns included |
With Amazon SES, your sending reputation is tied to your own AWS account. You control your domains, authentication records, and sending patterns. No other customer shares your sending reputation unless you explicitly use shared infrastructure. This isolation gives you full control over deliverability outcomes but also means you are fully responsible for maintaining that reputation through proper warmup, list hygiene, and content quality.
SendGrid cold email delivery works differently depending on your plan. Check their site for details on how they handle IP address assignment and whether shared or dedicated IPs are available on each tier. For cold email specifically, understanding how your IP reputation is managed matters because it directly affects inbox placement. SES gives you infrastructure tied to your own AWS account by default.
Choose AWS SES if you want the lowest per email cost, full control over your sending reputation, and plan to use a separate cold email tool for campaign management. SES is pure infrastructure, and it excels at that role. The technical setup is more involved, but the long term cost savings and reputation isolation make it the preferred choice for serious cold email operations.
Choose SendGrid if you want a more managed experience with built in analytics and delivery insights, or if your primary use case is transactional email alongside some outreach. SendGrid's higher level features reduce the amount of tooling you need to build or buy separately. For teams already on the Twilio ecosystem, the integration is straightforward.
EmailQo integrates natively with Amazon SES as a sending provider. You connect your SES SMTP credentials, and EmailQo handles campaign sequences, follow ups, sender rotation, and reply detection. AWS bills you directly at $0.10 per 1,000 emails with no markup from EmailQo. Every plan includes built in warmup for SES connected accounts and pre send inbox health checks that validate DNS, scan content, and check blacklists before each send.
