Flag numbers with no WhatsApp

Not every number on your list has WhatsApp. Wazzap detects which ones don't and stamps a tag on them so your workflows skip them, your bulk sends stay clean, and your delivery rate doesn't distort your reporting.

Overview

The No-WhatsApp tag watches every outbound send. If Wazzap detects that the destination number doesn't have an active WhatsApp account, it applies a designated tag (default no-whatsapp) to the contact in your CRM. The original message is not delivered, and your follow-up workflows can branch on the tag.

★

Pair this with an SMS fallback in your CRM workflow: when the no-whatsapp tag lands, fire an SMS instead so the contact still hears from you.

How it works

  1. You fire a WhatsApp send (one-off, bulk, or from a tag trigger).
  2. Wazzap attempts delivery. WhatsApp returns a status indicating the number has no account.
  3. Wazzap applies the configured tag to the contact and stops further WhatsApp attempts.
  4. The tag stays on the contact until you manually remove it. Future workflows can read it and route the contact elsewhere.

Setup

  1. Open the sub-account, then No-WhatsApp tag.
  2. Enable the feature.
  3. Choose the tag name to apply. The default is no-whatsapp.
  4. Save. The detection runs on every send from this number going forward.

Example

A bulk send to 1,000 contacts, 12 of which have no WhatsApp:

Send fires for all 1,000 contacts.
988 deliver successfully.
12 fail with "no WhatsApp account".
Wazzap stamps the tag "no-whatsapp" on those 12 contacts.
Your CRM workflow listens to that tag and fires an SMS fallback.

Result

  • You stop wasting bulk send credits on dead numbers.
  • Your delivery-rate reporting reflects only contacts that can actually receive WhatsApp.
  • Your team can choose to call, SMS, or email the no-WhatsApp segment without re-checking each number manually.

Important notes

  • The detection only fires when you actually attempt a send. Importing contacts does not pre-check them.
  • WhatsApp deactivations are not retroactive. If a contact deletes WhatsApp after you tag them, the tag stays. Remove it manually if needed.
  • The tag is local to your CRM, so your reports and segments treat it like any other tag.
  • You can rename the tag to anything you want, including emoji.

Troubleshooting

Some contacts get tagged even though they reply on WhatsApp

WhatsApp occasionally returns a false negative when the contact's app is mid-update or the number is on a multi-device setup that's not fully synced. Wait 24 hours and retry the send. If the contact replies, remove the tag.

The tag is never applied

The feature might be disabled at the sub-account level, or the chosen tag name conflicts with a reserved CRM tag. Re-check the setup screen and pick a unique tag name.
