WhatsApp messaging guidelines

What WhatsApp requires before you message registrants: permission, what you can and can't send, and how to keep your messages delivered.

WhatsApp has strict rules for business messages, and Meta, which runs WhatsApp, enforces them. Following them keeps your reminders delivered and your registrants glad to hear from you. Because every EasyWebinar host sends from shared EasyWebinar numbers, they also protect delivery for everyone.

At a glance

PermissionRequired before you message anyone on WhatsApp
Reminders and confirmationsAllowed for webinars people registered for
Offers and promotionsAllowed only with permission; charged and limited as marketing
Restricted topicsSome products can't be promoted on WhatsApp at all
Stopping messagesPeople can opt out at any time, and you must respect it

Get permission first

You can only message people on WhatsApp if they gave you their number and agreed to hear from you on WhatsApp. A phone number on a registration form isn't, on its own, that agreement.

  • Say on your registration page that you'll send reminders by WhatsApp, next to the Phone field or with a consent checkbox.
  • If you'll also send offers or replay promotions, say so too. WhatsApp recommends asking separately for reminders and for promotions.

You're responsible for how you collect permission and for the laws that apply where you and your registrants are.

What you can send

  • Confirmations and reminders for a webinar the person registered for.
  • Follow-ups after the webinar, such as the replay link.
  • Offers and promotions to people who agreed to receive them. These are marketing messages: charged at the highest rate, limited per person, and not currently delivered to US numbers.

What you can't send

WhatsApp doesn't allow messages that:

  • are spam, misleading, or pretend to be someone else;
  • ask for full card numbers, bank account details or government ID numbers;
  • promote products WhatsApp restricts, such as certain financial products, adult products, real-money gambling, dating services and multi-level marketing;
  • promote regulated products such as alcohol or medicines without WhatsApp's permission, or to anyone under 18.

If your webinar is about a restricted topic, keep WhatsApp to plain reminders and use email for promotion.

Let people stop

People must be able to stop your messages, and you must respect it, including when they ask by email or anywhere else. Someone who blocks the sender or opts out won't receive further messages.

Keep your messages delivered

When people block or report messages, WhatsApp lowers the sending number's quality rating and can limit how many people it can reach.

  • Keep reminders short and expected: the time, the topic, the join link.
  • Send only what's needed. A welcome message and one or two reminders is plenty.
  • Keep promotions out of reminders. It keeps them at the lower-cost utility rate and outside WhatsApp's marketing limits.
  • Test first with Send Test Message, so merge fields show real values.

Common questions

Is a phone number on my form enough permission?

Not on its own. Tell people you'll message them on WhatsApp, ideally with a consent checkbox.

Can I send offers on WhatsApp?

Yes, to people who agreed to receive them. They're charged at the marketing rate, limited per person, and not delivered to US numbers at the moment.

What if someone asks me to stop?

Stop messaging them, wherever they asked.

Can I promote anything I sell?

No. WhatsApp restricts some products and services. Use email for those.

Why do these rules matter if messages come from EasyWebinar's number?

Blocks and reports lower the number's quality rating, which affects delivery for every host who sends from it.
