Why Personalization Makes a Difference

Studies show personalized messaging can increase open rates by up to 50% and boost reply rates by over 70%, making it essential for driving customer engagement and loyalty.

Organize Your Contact List

Before you personalize messages, prepare your contact data:

Collect phone numbers and names in a spreadsheet, ensuring each number includes the correct country code and no spaces or special characters.

In Excel, choose File → Save As → CSV (Comma delimited).

In Google Sheets, select File → Download → Comma Separated Values (.csv).
Properly formatted CSV files guarantee seamless data import.

Map Your Data

RocketSend.io’s field feature lets you dynamically personalize each message:

Open WhatsApp Web and click the RocketSend sidebar.

Click Upload CSV and select your prepared file.

In the mapping interface, map the column that has the phone numbers.

Draft your message in the RocketSend editor. Use Insert Variable to add placeholders:
Hi {{first_name}}, we’re excited to invite you to our upcoming webinar on June 10. RSVP here: {{rsvp_link}} (if you have this already)
These automatically populate with each contact’s details, delivering a personal touch.
