WhatsApp marketing

Message your customers. From your phone.

Add your contacts, write once, tap send. No agency. No software to learn.

Works on your phone and in any browser. Sign in with your number.

How it works

Three steps. That's it.

If you can send a WhatsApp message, you can run a campaign.

01

Add contacts

Import a list, pick from your phone, or add one by one.

  • The wallet never expires
Permission first

Only people who said yes.

You choose who to message and you are responsible for their consent. Anyone who replies STOP is skipped from then on. Your contacts are yours: we never sell them or use them for our own marketing.

Questions

Good to know.

Do I need a WhatsApp Business account?

To send automatically, yes. Open Send helps you connect one through Meta's own sign-up window. Without it you can still use the manual queue.

Who owns my contacts?

You do. We hold them to run the service for you, and never sell them. See the Privacy Policy.

What stops people being messaged who don't want to be?

Anyone who replies STOP, or uses the stop button on a message, is marked unsubscribed and skipped from then on.

Is there an app?

Open Send runs in your web browser, and there is an iPhone app.

How do I sign in?

With your phone number. A one-time code arrives on WhatsApp.

How do I delete my data?

Follow these steps, or write to [email protected].
