Email Setup (Resend)

Set up transactional email via Resend — booking confirmations, tour reminders, review requests, and recovery emails.

Why Resend?

Resend is a developer-friendly transactional email service with excellent deliverability. The free tier allows 3,000 emails/month and 100/day — more than enough to start. Emails land in inbox (not spam) when your domain is properly verified.

Free tier

3,000 emails/month

Paid from

$20/month (50k emails)

Setup time

~15 minutes

Step 1: Create a Resend Account

Go to resend.com and sign up
Verify your email address
On the dashboard, click Domains → Add Domain
Enter bestphuketguide.com
Resend will show you DNS records to add to Cloudflare

Step 2: Verify Your Domain (DNS Setup)

Add these DNS records to your Cloudflare DNS panel for bestphuketguide.com:

SPF record (TXT):

Type: TXT
Name: @ (or bestphuketguide.com)
Value: v=spf1 include:amazonses.com ~all

DKIM record (TXT) — Resend provides the exact values:

Type: TXT
Name: resend._domainkey
Value: (provided by Resend — copy exactly)

Optional: custom MAIL FROM (improves deliverability):

Type: MX
Name: send.bestphuketguide.com
Value: feedback-smtp.us-east-1.amazonses.com
Priority: 10

Tip: DNS changes propagate in 5-60 minutes. Resend will automatically check and show a green "Verified" status once the records are live.

Step 3: Create an API Key

In Resend dashboard, go to API Keys → Create API Key
Name it bestphuketguide-production
Set permission: Full access
Copy the key (starts with re_)
Add it to your Cloudflare Worker secrets:

wrangler secret put RESEND_API_KEY
# Paste the key when prompted

Warning: Never commit the Resend API key to git. Anyone with the key can send emails from your domain.

Email From Address

Emails are sent from your verified domain. Configure the from address in Settings → Notifications:

From: Best Phuket Guide <bookings@bestphuketguide.com>
Reply-To: info@bestphuketguide.com

Tip: Use a subdomain like bookings@bestphuketguide.com for transactional email so replies to booking emails go to your main inbox.

Testing Email Delivery

Go to Settings → Notifications
Find the Test Email section
Enter your email address and select a template (e.g. Booking Confirmation)
Click Send Test
Check your inbox — should arrive within 30 seconds
Also check spam folder on first test — if it lands there, check DNS records

Check delivery logs in:

•Resend dashboard → Emails — see all sent emails and delivery status
•Admin → Emails — the email log page shows all notifications sent by the platform

Troubleshooting

Emails landing in spam?

• Check that SPF and DKIM DNS records are correctly set and verified in Resend
• Make sure the from address uses your verified domain
• Avoid spam trigger words in subject lines (FREE, URGENT, CLICK HERE)
• Ask a few early customers to mark the email as "not spam" — this improves domain reputation

Emails not sending at all?

• Check the Email Log page — if status is "dev mode", RESEND_API_KEY is not set
• Run wrangler secret list to verify the secret exists
• Check Resend dashboard for API errors
