The Resend Dashboard

Resend gives you a dashboard where you can do all of this.

View sent emails. See every email your app has sent
Check delivery status. Know if emails were delivered or bounced
Monitor engagement. See who's opening and clicking (once tracking is on, more on that below)
Manage domains. Set up and verify your sending domains
View analytics. Understand how your emails perform

That visibility is HUGE. When somebody swears they never got your email, you can go check whether it was sent and delivered instead of guessing.

Setting Up Resend

Here's how you get going.

Step 1. Create Account

Step 2. Add Your Domain

Add the domain you'll send emails from. Resend hands you some DNS records to add.

Step 3. Verify Domain

Add those DNS records in your domain settings. That's how you prove you own the domain.

Step 4. Get API Key

Generate an API key to use in your app.

Step 5. Send Emails

Use the Resend SDK in your code and start sending.

Pricing

Resend keeps pricing pretty simple. Here's what it looked like as of October 2026 (check resend.com/pricing for the current numbers).

Free. 3,000 emails per month, max 100 per day, 3 domains
Pro. Starting at $20/month for 50,000 emails

For most apps, especially early on, the free tier is plenty. Just know about that 100 a day cap, because a busy launch day can hit it way before you hit the monthly number.

Email Best Practices

Step 1. Only Email People Who Expect It

Never send emails nobody asked for. Only email people who signed up and expect to hear from you.

Step 2. Include Unsubscribe Links

Every marketing email needs an easy way to unsubscribe. In a lot of countries it's literally the law.

Step 3. Keep It Simple

Don't cram your emails full of images and fancy designs. Simple emails often land better anyway.

Step 4. Test Before Sending

Send a test to yourself first. Check how it looks on mobile AND desktop... it's way less embarrassing to catch a broken layout in your own inbox.

TL;DR

Sending email reliably is surprisingly hard, so use a service like Resend
Resend handles spam filters, authentication and deliverability for you
You need your own domain to send emails
Common emails include welcome messages, password resets, notifications and receipts
React Email helps you build good-looking email templates
The free tier allows 3,000 emails per month
