# Email: tools in this layer of The Stack

> Transactional and marketing. 4 tools, from Nicolas Dao's defaults to what he would never use (Cloudless Labs, Sydney).

- Web page: https://cloudlesslabs.com/stack/layers/email/

## My default

- [Resend](https://cloudlesslabs.com/stack/resend/index.md), Transactional and marketing email: My email service. Transactional and marketing on one platform, built for developers and agents.

## Use when it fits

- [Amazon SES](https://cloudlesslabs.com/stack/aws-ses/index.md), Email when data must stay in AWS: The cheapest email at volume, and the only one that keeps data in Sydney. The sandbox is a pain.

## Skip

- [Postmark](https://cloudlesslabs.com/stack/postmark/index.md), Transactional email: The best deliverability reputation, but no marketing platform, no idempotency and unsigned webhooks. I picked Resend. Instead: Resend: transactional and marketing on one platform, with idempotency keys and signed webhooks.

## Never

- [Amazon Pinpoint](https://cloudlesslabs.com/stack/aws-pinpoint/index.md): Reaches end of support on 30 October 2026. Don't start anything on it. Instead: Resend, for transactional and marketing email on one platform.
