The number
Start with your own number
Connect through Meta in a few clear steps. The number, WhatsApp Business account and Meta payment method stay under your company; Masar manages the sending workflow.
Your messages, from your number
Send WhatsApp campaigns from your number. See every message and every charge.
Connect your number and upload your list. Meta bills WhatsApp usage directly to your business, while Masar shows its management fee before you send. The two charges stay separate.
The Masar team reviews your account before enabling sending. You can prepare your data while you wait, and we will notify you when a decision is made.

A simple start
Three steps to send a campaign
Three ordered steps. At each one, you can see what happened and what needs your decision.

The list
Upload your list and review the import results
After a CSV upload, you see what was accepted, what was refused, and the line number that needs fixing. We do not guess ambiguous numbers.

03
Send
Review the fees, then send
You see Masar’s management fee before launch. It is reserved once, then sent messages draw it down and unsent fees return. Meta bills WhatsApp usage separately and directly.
Two clear bills, no double charge
Meta bills WhatsApp usage. Masar bills management only.
WhatsApp message charges go directly to your Meta business account. Your separate Masar balance covers management and operations, and every balance change is itemized.
Campaign statement
Every balance change is linked to the campaign that caused it
-
1 Before sending
A clear Masar fee
We calculate the management fee over your actual audience and show it beside the send button. It never bundles what Meta bills to your account.
-
2 At launch
One reservation
The management fee you approve is reserved in one movement, then drawn down as messages go out.
-
3 Automatically
Fees returned for messages not sent
Masar’s fee for anything WhatsApp refuses or confirms as failed returns to your Masar balance. Meta’s charges remain visible in your Meta billing account.
-
4 Always
Every balance change is itemized
Masar top ups, management fees, refunds and settlements appear on one statement, clearly separate from Meta’s invoice.
Protect your number
Someone who asked you to stop will not receive the next campaign.
Number health does not begin after reports arrive. It begins with clear proof of consent and a check that runs for every send.
What Masar checks before and during a campaign
- Real proof of consent
- When, where and how the person agreed. A row claiming consent without evidence is refused with the reason.
- Checked at send time
- If someone opts out after the campaign is prepared but before their turn, Masar skips them.
- STOP works in Arabic and English
- An opt out reply is applied automatically on the number that received it and survives a later reimport.
- The campaign pauses when failure rates rise
- If more than a third of attempts fail, the campaign pauses and tells you instead of consuming the rest of the list.
This protection is part of the sending path, not a setting you have to remember to turn on.

Questions about WhatsApp Business campaigns
Answers about connecting your number, customer consent, campaign costs, and integrations.
Can I send from a WhatsApp Business number I already own?
Yes, when the number is eligible to connect. The Masar team reviews the account and number first, then shows the connection status and the next required step before sending is enabled.
Can I send bulk messages to any contact list?
Campaigns are for customers who agreed to receive messages through WhatsApp or the selected sending service. Masar keeps the consent evidence, checks it at send time, and respects opt-outs before another message leaves.
How do I know a WhatsApp campaign cost before launch?
Meta shows and bills WhatsApp usage in your business account. Masar shows its separate management fee before confirmation, then returns the fee for anything unsent to your Masar balance. You never pay Meta’s charge twice.
Do I need approved message templates?
Business-initiated messages need a usable template under WhatsApp rules. Masar shows each template status and will not send one whose current state does not allow it.
Can I connect Masar to my website or CRM?
Yes. The platform provides a scoped REST API, an OpenAPI specification, and signed webhooks for message status and event updates inside your own system.
