What is WhatsApp broadcast?

A WhatsApp broadcast sends one approved message template to many contacts at once through the official WhatsApp Business API.

Read the full explanation

Unlike the WhatsApp Business app (256 contacts per list, only people who saved your number), ConvoBox broadcasts reach any opted-in contact, carry images, videos, documents and buttons, and report delivery, read and click rates per campaign. Broadcasts are used for product launches, sale announcements, festival offers, event reminders, newsletters and re-engagement campaigns. In ConvoBox you choose an audience by tags, CRM stage, imported list or Google Sheet, personalise each message with variables such as the customer's name, schedule the send for the best time, and follow up automatically with anyone who taps a button. Replies land in the shared team inbox so your team can close sales from the same campaign. Each number has a daily sending limit set by Meta that rises as customers engage, and a built-in unsubscribe option keeps opted-out contacts out of marketing sends.

Broadcast templates, as your customers see them

Every broadcast is an approved WhatsApp template. Pick a format to see it on the phone.

WhatsApp broadcast questions

Short, direct answers. Still unsure? Message the team on WhatsApp.

How many contacts can I broadcast to on WhatsApp?

With the WhatsApp Business API there is no fixed list size. Meta assigns each number a daily limit on how many unique customers it can message, which starts low for new numbers and rises step by step, up to unlimited, as customers keep engaging with your messages. The current tiers are published in Meta's WhatsApp Business Platform documentation. ConvoBox sends within that limit and shows it in the dashboard.

Will my number get blocked for broadcasting?

Blocks happen when unofficial tools send unapproved messages. ConvoBox uses the official API and Meta-approved templates, includes an unsubscribe option, and lets you segment so people only get relevant offers, which keeps your quality rating healthy.

Can I schedule a WhatsApp broadcast?

Yes. Choose a date and time when creating the broadcast. You can edit or cancel a scheduled campaign until it starts sending.

What does "retry failed numbers" do?

After a campaign finishes, ConvoBox lists the numbers that failed (for example, a phone that was off for days). Retry resends the same template only to those numbers, so nobody receives it twice.

Can I see who read or clicked my broadcast?

Yes. Broadcast analytics show sent, delivered, read, clicked and failed counts for the campaign, and the status for each contact.

How much does each broadcast message cost?

ConvoBox plans are a monthly subscription. Meta charges a per-message fee for marketing and utility templates at its published rate for India, billed alongside.

What is the difference between a WhatsApp broadcast list and a ConvoBox broadcast?

A broadcast list in the WhatsApp Business app reaches up to 256 people, and only those who saved your number. A ConvoBox broadcast uses the official WhatsApp Business API and approved templates, so it can reach any opted-in contact within your Meta messaging limit, with images, buttons, scheduling and analytics.

Can I send images, videos and PDFs in a broadcast?

Yes. Templates can have an image, video or document header, plus up to three buttons such as a website link, a phone call or quick replies.

Can each message be personalised?

Yes. Template variables fill in each contact's name, order ID, coupon code or any custom field you have.
