Photo above text

WhatsApp shows the picture of the first link in a message above the text. Blitzchat makes a small page for your photo on your own free Netlify website and adds its link to the end of the message. Wait a second for the photo to appear in WhatsApp, then press Send.

Open Netlify → User settings → Applications and sign in.
Under Personal access tokens, click New access token, name it Blitzchat, choose no expiry, and copy the token.
Paste it below, choose a link name and click Connect.

Netlify access token

Link name (customers see this)

Photo pages are public: anyone with the link can see the photo and title. Your leads are never uploaded there. The token is kept on this device only.

Passcode lock

Ask for a 6-digit passcode every time Blitzchat opens. Your leads are encrypted on this device, so no one can read them without the passcode. If you forget it, the leads on this device can't be recovered, so turn on Google Sheet backup too.

Google Sheet backup

Create a new Google Sheet to be your master file, named something like Blitzchat Master Leads.
Click Copy script below. In the sheet, open Extensions → Apps Script, delete what's there and paste.
Click Deploy → New deployment, pick Web app, set Execute as: Me and Who has access: Anyone, then Deploy. Allow access when Google asks.
Copy the Web app URL, paste it below and click Connect.

Web app URL

Your leads are backed up automatically to Blitzchat Backup, a Google Sheet in your own Google Drive. Only you can see it. Sign in with the same Google account on your phone, iPad or computer and your leads follow you.

New imports and status changes are backed up automatically a few seconds after they happen. Leads are matched by phone number, so the master sheet never has duplicates. Clearing data here never deletes rows in the sheet.

Connect another device (iPad, phone)

Copy this code, open Blitzchat on the other device, go to Backup and paste it into the Web app URL box.

Your leads are saved in your own Google account. Keep the Web app URL private: anyone with it could add rows to your sheet.

Mark replies

Paste the numbers of people who replied, from WhatsApp or anywhere. Any format works, one or many per line. They're marked Replied with today's date, a remark is added, and they're left out of future sends.

Add to remarks (optional)

Import leads

Choose a .csv or Excel .xlsx / .xls file, or drag it anywhere on the page. With Excel, every sheet tab is imported, and the tab name is saved as the lead's source.

Paste the link to your Google Sheet. First set it to Share → General access → Anyone with the link (Viewer). Open the tab you want before copying the link, because only that tab is imported.

One number per line. You can put a name in front, like Ahmad, 012-345 6789. Numbers starting with 01… are treated as Malaysian, and 8-digit numbers starting with 8 or 9 as Singaporean.
