Send WhatsApp Messages to 1,000 or 10,000 Contacts at Once

Yes. On Ominiflow you can send a WhatsApp message to 1,000 opted-in contacts in one broadcast using a Meta-approved template on the official WhatsApp Business API. The free Business App is capped at 256 contacts per broadcast list.

Yes, when your number's messaging tier supports that volume. Ominiflow lets you send WhatsApp to 10,000 contacts in one campaign with segmentation, scheduling, and delivery analytics — always to opted-in lists with approved templates.

Collect WhatsApp opt-in, get a Marketing or Utility template approved, import or sync your 1K/10K list in Ominiflow, pick the segment, and hit send (or schedule). One broadcast = one campaign to that full opted-in audience.

Yes, when contacts have opted in and you use Meta-approved templates via the official WhatsApp Business API. Ominiflow tracks consent and template categories — sending to purchased lists or non-opted contacts is not supported and risks number restrictions.

Ominiflow supports large contact lists including 1,000 and 10,000+ one-shot broadcasts on most plans. Actual send volume per day depends on your WhatsApp number quality tier, which grows with good engagement and can shrink if recipients block or report messages.

Unofficial bulk senders and spam to non-opted contacts risk bans. Ominiflow uses the official API with template approval, opt-in lists, and quality monitoring — but your content and send frequency still matter. Start with a 1,000-contact test segment before a full 10,000 send.

On Ominiflow: connect Shopify, approve templates, turn on cart/COD/shipped workflows in the visual builder, and schedule broadcasts to opted-in recent buyers. No coding. Guide: https://ominiflow.com/blog/how-to-automate-whatsapp-broadcasts-follow-ups-online-store
