Question 1

Do I need a WhatsApp Business API account?

Accepted Answer

No — Zellbox handles the Meta registration via the Embedded Signup popup. Bring an existing number or get a new one from Meta.

Question 2

How much does it cost to send reminders?

Accepted Answer

Meta charges per conversation initiated. Zellbox passes through the exact Meta price — no markup.

Question 3

Is there a free trial?

Accepted Answer

The free tier itself is the trial — no credit card required. 50 customers, 50 appointments per month, 100 WhatsApp messages on the shared Zellbox number. When you're ready, upgrade in one click. Paid plans are month-to-month, no annual lock-in.

Question 4

How long does the setup take?

Accepted Answer

Creating your account: about 2 minutes. Connecting your own WhatsApp number via Meta: about 10 minutes plus Meta's verification for any new templates (usually a few hours).

Question 5

What happens to my existing WhatsApp Business number?

Accepted Answer

If you bring an existing WhatsApp Business number, you migrate it to Meta's Cloud API during the Embedded Signup. Your customer history on Meta's side stays intact.

Question 6

Can I switch from my current system?

Accepted Answer

Yes — bulk-import your customers from a CSV or XLSX export. Most teams finish the migration in under an hour. We don't lock you in: you can export your data at any time in the same format.

Question 7

What channels does Zellbox bring together?

Accepted Answer

Google Calendar, Gmail, and WhatsApp Business — all managed from one screen in Zellbox. No more juggling separate tabs. Calendar sync is two-way: visits scheduled in Zellbox appear in Google Calendar, and changes in Google Calendar update Zellbox.

Question 8

How does this compare to using WhatsApp + a spreadsheet?

Accepted Answer

A spreadsheet doesn't fire reminders automatically, doesn't track delivery, doesn't route replies to the right operator, and doesn't scale past a few dozen customers. Zellbox handles all of that and treats WhatsApp as a first-class channel instead of a side-task.

Question 9

What about data protection (GDPR / LOPDGDD)?

Accepted Answer

Zellbox complies with GDPR and LOPDGDD. We use European host providers for customer data where required, sign a Data Processing Agreement on request, separate consent for operational versus marketing messages, and encrypt all data at rest and in transit. Every workspace is isolated from every other.
