How we use Resend

Resend sends the one-to-one email: receipts, alerts, password resets, support replies and the short notes our AI writes to customers. Kit is for lists, Resend is for one person at a time.

Resend's public homepage — Resend's own public page, captured Oct 30, 2026. We show the vendor's page, not our account.

The actual workflow

Each product sends from its own domain through the Resend API, with a copy to a shared inbox.
A delivery check runs on a schedule and flags bounces or anything stuck.
Templates live in code next to the product, so a change ships with the rest of the site.

What it replaced

Sending from a personal mailbox, which lands in spam and leaves no log.

Rough cost for a setup like ours$0–$20/mo. The free tier covered us for a long time.

List price (Oct 27, 2026)Free for 3K emails/mo (100 a day). Pro from $20/mo.

Tips

Set up SPF, DKIM and DMARC on day one. Deliverability problems are much harder to fix later.
BCC a shared inbox on everything. It is the cheapest audit trail there is.

Gotchas

There is no friendly editor. Every template is code.
The free tier caps daily sends, which bites during a launch.
