Mail Merge Personalization Preview

Paste your email template with {{placeholders}} and a CSV of recipients. Preview every personalized email and catch missing fields before you hit send.

Email template

Recipients (CSV with header row)

Runs entirely in your browser. Nothing is uploaded or stored.

How it works

STEP 1

Paste your template

Write your email with {{first_name}}, {{company}} or any placeholder you like — one per column in your CSV.

STEP 2

Add your recipients

Paste a CSV (with a header row) or type values separated by commas. Each row is one recipient.

STEP 3

Preview & fix

Flip through each merged email. Any missing or empty field is highlighted in red so you can fix it before sending.
