Newsletter

Send newsletters directly from the editor using your own Resend API Key — no mail server setup required.

Resend Free Tier

3,000 emails per month, up to 100 recipients per send — completely free, no credit card required.

Setup Steps

1

Sign up for Resend and get an API Key

Visit resend.com and create an account. Go to "API Keys" in the left sidebar, click "Create API Key", give it a name, and copy the generated key (format: re_xxxxxxx). 

https://resend.com
2

Verify your sending domain

In the Resend dashboard, go to "Domains" → "Add Domain". Follow the instructions to add MX, SPF, and DKIM records at your DNS provider — these typically propagate within 15 minutes.

For testing, you can use Resend's built-in onboarding address: 

onboarding@resend.dev
3

Configure in the editor

Click the "Newsletter" panel in the editor top bar and enter:

  • API Key : paste the re_xxxxxxx key copied above — it is saved automatically to localStorage
  • From address : must be an address under a domain you have verified in Resend, e.g. hello@yourdomain.com
4

Enter recipients and send

Fill in the email subject and recipient list in the Newsletter panel (one address per line, or comma-separated, up to 100 recipients). Click "Preview Email" first to verify the HTML rendering, then click "Send" and confirm in the dialog.

Important Notes

  • Your API Key is stored in browser localStorage. Clearing browser data will erase it — store it somewhere safe separately.
  • Always click "Preview Email" before sending to verify how the HTML renders in email clients.
  • Maximum 100 recipients per send. For larger lists, send in batches to stay within Resend's free tier limits.
