Mail Merge
Everything runs in your browser. Your file is never uploaded.
1. Load spreadsheet
Choose an Excel file and pick the sheet with your recipients. The first row must hold the column names, and one column must contain the email addresses (named Email, E-mail, Mail or Correo). Each row after that is one recipient.

2. Write the email
Write the subject and the body. To personalize them, choose a column and click
+ Insert: this adds a tag like {{Name}} where your cursor is, and each
tag is replaced with that recipient's value. When you're done, click Generate.
3. Send
Go through the list one address at a time. Clicking an address copies that person's email to your clipboard and opens your mail app with the recipient and subject filled in. Click into the empty body, paste (Ctrl+V), check it and press Send. A ✓ marks the addresses you've already opened. Nothing is sent until you press Send in your mail app.
