# Why transactional email providers cost more than SES

The gap at 100,000 emails a month is roughly 3x to 13x. Here is what it actually buys, and when paying it is the right call.

Sending 100,000 transactional emails through Amazon SES costs about $10. The same volume is $35 on Resend Pro, $34.95 on SendGrid Essentials, and $126 on the cheapest Postmark plan that reaches it.

That spread is not a markup on bandwidth. Sending an email is nearly free for everyone involved, SES included. The difference is paying somebody to have already solved a specific set of problems, and the useful question is which of those problems you actually have.

## The spread at 100K/month

| Provider | Monthly | What that is |
| --- | --- | --- |
| Amazon SES (à la carte) | $10 | $0.10 per 1,000. Sending only — no dashboard, no templates, no queue. |
| Amazon SES (Essentials) | $16 | $0.16 per 1,000. The plan AWS puts new accounts on by default since July 2026. |
| Resend Pro | $35 | 100K included. Logs are purged at 30 days on every plan below Enterprise. |
| SendGrid Essentials | $34.95 | 100K tier. Three days of activity history; longer is a paid add-on. |
| SendGrid Pro | $89.95 | 100K tier. Adds a dedicated IP, seven days of history, and subuser management. |
| Resend Scale | $90 | Also 100K. The step up from Pro at the same volume, not a bigger bucket. |
| Postmark Platform | $126 | $18 base for 10K, then $1.20 per additional 1,000. |
| Postmark Pro | $133.50 | $16.50 base for 10K, then $1.30 per additional 1,000. |

## What the difference buys

### IP reputation, warmed and watched

The largest line item, and the one you cannot buy separately. A provider runs pools of addresses with years of sending history, moves customers between them, and employs people who talk to mailbox providers when something goes wrong. You are renting a relationship with Gmail that took a decade to build.

### Somebody else on call

When a queue backs up at 3am it is their pager. On SES the equivalent failure is your Lambda, your dead letter queue, and your morning.

### Compliance and abuse work

Feedback loops with every major ISP, complaint processing, list scrubbing, and the team that catches an abusive sender before they poison the pool your mail is also in. Invisible until it fails.

### The product on top of the pipe

Dashboards, per-message event search, template storage, suppression, retries, sandboxes. SES gives you an API call and a firehose of events. Everything you would then build is what the difference pays for.

### Support with a human on it

AWS support is a paid add-on and its first tier will not debug your deliverability. A transactional provider's support answers email questions specifically, because that is the only product they have.

## The comparison is not $10 against $35

This is where the SES argument usually cheats. The $10 buys an API that accepts messages and emits events. It does not buy the queue that absorbs a retry storm, the consumer that writes delivery history somewhere you can query it, the suppression enforcement, or the dashboard someone in support opens when a customer says the invoice never arrived.

Build those and the AWS bill grows by a few dollars for Lambda, SQS, EventBridge and DynamoDB, which is a rounding error. The engineering does not. A first pass is usually a couple of weeks, and it is never finished, because bounce classification and reputation monitoring are the sort of thing you improve after every incident.

So the honest framing is not cheap versus expensive. It is whether you want to own that surface. A team with no AWS practice and no appetite for one should pay SendGrid and stop reading here — that is a real answer and it is right for a lot of companies.

## When the markup stops making sense

-   You already run on AWS. The account, the IAM discipline, and the on-call rotation exist. The marginal cost of one more serverless pipeline is much lower for you than for a team starting from nothing.
-   Volume is climbing. Provider pricing is per-email and SES is too, but the multiple is what compounds. At 5 million a month the same spread is thousands of dollars against a few hundred.
-   You need the data to stay put. Message content and delivery events living in your own account is a different compliance conversation from a vendor's retention policy.
-   You want the reputation to be yours. On a shared pool a neighbour's bad week is your problem. On your own SES account there are no neighbours, which cuts both ways.

## Where Wraps sits

We build the third option, so weigh this accordingly: the infrastructure deploys into your AWS account, AWS bills you for sending at its own rate, and we charge a flat monthly platform fee that does not move with volume. You get the product surface without the per-email markup, and you inherit the parts a provider was absorbing for you.

Those parts are real. Your SES account starts in the sandbox, your reputation starts at zero, and nobody at AWS is going to warm a domain for you. If what you were paying SendGrid for was somebody else owning deliverability, moving to any bring-your-own-cloud option means taking that back.
