Resend (email)

Send transactional and marketing email from your own domain. SeldonFrame uses Resend under the hood — fast, deliverable, modern API.

Setup

1

Get a Resend API key

Go to resend.com, create an account, and create an API key.
2

Add a sending domain

In Resend's dashboard → Domains → "Add domain." Enter your domain (e.g. yourbiz.com). Resend gives you DNS records (SPF, DKIM, DMARC) to add at your registrar.
3

Add the DNS records

Three TXT records typically — exact values come from the Resend dashboard. Example shape:
TXT  send._domainkey   <DKIM record>
TXT  resend._domainkey  <DKIM record>
TXT  @                  v=spf1 include:resend.com ~all
4

Connect Resend to SeldonFrame

Settings → Integrations → Resend → paste your API key and the domain you verified.

Don't skip DKIM

Email deliverability without DKIM is rough. Gmail and Microsoft will quietly route you to spam. Always verify DKIM before sending marketing email.

What sends through Resend

  • Booking confirmations and reminders.
  • Forms confirmations.
  • Customer Portal magic-link logins.
  • One-off and broadcast emails.
  • Agent-triggered follow-ups.

From-name and reply-to

Default from-name is your workspace's display name. Default reply-to is your account email. Override per-template or per-send.

Costs

Resend bills you directly. The free tier covers 100 emails/day — enough for booking reminders for a small operation. Paid tiers scale up from there.
