What makers say

Makers on using it for transactional email, from Product Hunt and Starter Story interviews, each linked to the source. Products with a page of their own and fuller notes first.

On Postmark

We use Postmark not only for our emails, but also to power Ply's built-in dynamic email capabilities. It's reliable, well documented and most of all - comes with awesome human support.

Ply, the makerSep 2026 ↗

We use some integrations that nowadays have become basic for our business like Postmark (for transactional emails) or Sift (to detect users with not very good intentions).

LabsMobile, the makerDec 2021 ↗

Once you get familiar with Postmark's layouts and templates, the service is great for quickly creating email templates and sending them out using their simple API. The UI is simple and intuitive.

On Resend

SendGrid and Mailgun still work but feel like 2015. Resend has the cleanest API and React-based email templates, so all my transactional mail took an afternoon instead of a sprint.

VC Boom, the makerSep 2026 ↗

Resend handles all of MusicLib's transactional emails — verification, password resets, reservation confirmations. Clean API, great deliverability, took about 15 minutes to integrate.

Loved and watch-outs

Themes that recur in makers' words and Hacker News comments, each linked to what it summarises.

Postmark

Most loved

Its reputation for transactional mail gives strong inbox deliverability. PH HN HN 2
The API is simple enough to use with plain curl, and templates and layouts speed up building emails. PH HN HN 2
Inbound email processing is built in, so apps can receive and parse replies. PH HN HN 2

Watch-outs

Opening up to broadcast mail and ActiveCampaign ownership worry some that its deliverability edge will erode. HN HN 2
There is no built-in idempotency, so preventing duplicate sends needs locks and metadata checks. HN

On Product Hunt: 5.0★, 22 reviews · mentioned most: reliable email delivery, fast performance, human support

Resend

Most loved

The API is clean and TypeScript-first, simple enough to call with a plain fetch and no SDK. PH PH 2
Transactional email goes live within a day, with DNS setup and deliverability basics handled. PH PH 2
The free tier is generous enough to build and test before paying. PH PH 2 HN HN 2

Watch-outs

It runs on AWS SES, so an AWS us-east-1 outage stopped both its dashboard and email sending. HN PH
API gaps remain, such as the broadcast API not returning email content and no stored copy of sent threads. HN HN 2
