What is Resend?
Resend is a professional email delivery service. We use it to ensure your emails are delivered reliably. Creating an account is free and takes less than a minute.
Create a Resend Account
Visit Resend.com and sign up for a free account. You just need an email address to get started.
Go to Resend Sign UpVerify Your Email
Check your inbox for a verification email from Resend and click the verification link.
Navigate to API Keys
After logging in, click 'API Keys' in the left sidebar menu of your Resend dashboard.
Go to API Keys PageCreate a New API Key
Click the 'Create API Key' button. Give your key a name like 'Email Platform'.
Important: Select "Full access" Permission
When creating your API key, you must select "Full access" permission, NOT "Sending access". The "Sending access" option only allows sending emails, but features like Sync Contacts require full API access to work properly.
If you see the error "This API key is restricted to only send emails", please delete your current API key and create a new one with "Full access" permission.
Copy Your API Key
After creating the key, copy it immediately. The key starts with 're_' and will only be shown once!
Paste It Above
Paste the API key you copied into the 'Resend API Key' field above, then click 'Save Settings'.
Keep Your API Key Private
Your API key is like a password. Never share it publicly or with anyone you don't trust. If you think your key has been compromised, delete it in Resend and create a new one.
Testing Without Your Own Domain
If you don't have your own domain yet, you can use delivered@resend.dev as the sender email for testing. This allows you to test the platform before setting up your own domain.
For syncing contacts with Resend Segments. Find it at resend.com/audience → Segments → Your Segment → ID
