Benefits

Why send your campaigns from yavendió!

Besides sending, yavendió! answers whoever replies and shows what each campaign sold.

Your agent sells to whoever replies

When a customer replies, your AI agent answers right away: it finds the product, confirms the size and sends the payment link.

Your customers and their purchases are already in

Anyone who messaged or bought from you shows up in Contacts. Filter by purchases, order value or repurchase, no spreadsheets.

yavendió! CRM contact list with purchases and consent status

Recurring campaigns run on their own

Repurchase, abandoned cart, order confirmation and leads who never bought: turn them on once and each customer gets the message at the right time.

Create campaign: a one-off send or an automation

Guardrails that protect your number

Official API, Meta-approved templates and only contacts with consent, at most once a week. If opt-outs reach 2%, the campaign pauses on its own.

Advanced filters: at least 1 purchase and consent granted

You know what it costs and what it sold

Before sending you see the cost. After, each campaign shows delivered, read, replies and orders.

How do you send bulk WhatsApp messages the official way?

You need three things, and in yavendió! all three live in the CRM menu.

  1. 01

    Contacts who opted in

    Anyone who messaged or bought from you is already in Contacts, with consent marked.

  2. 02

    A Meta-approved template

    You write the message and Meta approves it before the first send.

  3. 03

    Balance per delivered message

    You only pay for what arrives, and see the cost before sending.

Use cases

Campaigns you can send

Repurchase, cart, confirmation and unconverted leads come ready: turn them on once and they go out on their own.

Automatic

Repurchase

Messages each customer when it is time to buy again, based on the product cycle. No purchase? A second nudge 3 days later.

Hi Ana 👋 Your serum must be running low. Want me to set another one aside?

Automatic · connect your store

Abandoned cart

When your online store reports a half-finished cart, the rescue message goes out with the product that was left.

You left the linen dress in your cart. Want help finishing the order?

Automatic

Order confirmation

As soon as an order comes in, the customer gets the confirmation. It is a utility template, cheaper than a marketing one.

Done, Ana. Your order #1043 is confirmed. We will let you know when it ships.

With your shipping system

Order on its way or ready for pickup

Tells the customer the order shipped or is ready to pick up. Goes out on its own if you connect your shipping system via API.

Your order #1043 has arrived and is ready for pickup from today.

Automatic

Leads who never bought

For people who messaged you and never bought: one message, a 2-day wait and another one if they did not reply.

Hi Luis, any questions about the styles you saw? I can set them aside for you.

One-off send

Launches and restocks

A new collection, a product back in stock or a date like Mother’s Day: pick the segment and send now or schedule it.

The Violet perfume is back 💜 Only a few left, want me to save you one?

FAQ

WhatsApp bulk messaging

You pay per delivered message, Meta fee included: US$ 0.0773 for a marketing message to Peru and US$ 0.0688 to Brazil. A promotion to 1,000 customers in Brazil costs US$ 68.80. The balance is prepaid and separate from your plan; each send to a customer without an open conversation also starts one from your plan, even if they do not reply.

With tools that send from WhatsApp Web, yes: WhatsApp says most bans come from unauthorized bulk messaging. On the official API, Meta can limit a number that gets many reports. So campaigns only reach contacts with consent, at most once a week, and pause on their own when opt-outs hit 2% or failures 10%.

Yes. From October 1, 2026 WhatsApp also charges the messages your agent sends when it answers customers, at each market utility rate. Conversations that start from an ad stay free for 72 hours.

Your AI agent answers: it finds the product in your catalog, confirms size or variant and sends the payment link in the same chat.
