What Does This Feature Do?
As an agency, you often have a list of potential clients — local businesses, leads from a directory, or prospects from an event. The fastest way to win them over is to show, not tell: send each prospect a personalized website demo along with a professional outreach email. Batch Generation and Cold Email let you do exactly that at scale:- Upload a spreadsheet (CSV) of your prospects
- Auto-generate a tailored website for every single one
- Send personalized cold emails with each prospect’s website link
Part 1: Batch Generate Websites
Step 1: Prepare Your CSV File
A CSV file is a special spreadsheet format that you can create with Excel or Google Sheets.Fill in the header row
The first row contains column names. You must include an
email column. You can add other columns as needed, for example:| name | description | phone | address | |
|---|---|---|---|---|
| Baker Shop | Handmade baking for 10 years | zhang@example.com | 13800001111 | No.1 Happy Road |
| Flower Store | Fresh flower delivery | li@example.com | 13800002222 | No.2 Sunny Road |
Fill in the data (starting from row 2)
From the second row onward, each row represents one client. Each row will generate one website.
