ready-made automations: repurchase, cart, order and unconverted leads

How do you send bulk WhatsApp messages the official way?

On the official WhatsApp Business API you need three things: contacts who agreed to hear from you, a template approved by Meta and a balance that pays for each delivered message. Tools that send from WhatsApp Web run your number outside the rules, and WhatsApp says most bans come from unauthorized bulk messaging.

In yavendió! all of that lives in the CRM menu. Your WhatsApp and order customers are already in Contacts, each one with their consent status. You build the audience with filters for purchases, order value or expected repurchase, pick the template and see how many people get it and what it costs before you send. Recurring campaigns, like repurchase or abandoned carts, run on autopilot. When someone replies, your AI agent answers with your catalog and a payment link.

Use cases

The campaigns your agent sends for you

Repurchase, cart, order confirmation and unconverted leads come ready in Campaigns: turn them on once and they go out when it is time. If the customer replies, your agent keeps the chat going and charges.

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.

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?

What it looks like

From your customer list to the send, in 5 screens

1

Your customers are already in Contacts

Anyone who messaged you on WhatsApp or bought from you shows up on their own, with their consent status. Have another list? Upload a CSV with name and phone. Importing does not grant consent: those contacts still need to opt in.

2

Filter who you message

Combine number of purchases, average order value, last purchase, expected repurchase, tag or country. Save the filter as a segment and it updates itself as new customers come in.

Advanced filters: at least 1 purchase and consent granted

Build the send in 3 steps

Name, Meta-approved template and audience. Send now or schedule it, and see the message exactly as the customer will. The preview tells you who gets it, who is left out and why, and the cost against your balance.

Pay only for what gets delivered

The balance is prepaid and separate from your plan. To Peru, a marketing message costs US$ 0.0773, and from October 1 a utility one costs US$ 0.0330, Meta fee included. If the balance hits zero, the campaign waits and resumes when you top up.

Or let it run on its own

Ready-made automations win back people who never bought, remind customers to repurchase on the product cycle and confirm every order. A contact leaves the sequence as soon as they buy or reply.

  • Doesn't know who bought or who opted out
  • Replies land on your phone and someone has to answer them

  • Only contacts with consent get it, and opt-outs stay out
  • Filter with your orders: purchases, order value, last purchase, repurchase
  • When a customer replies, your AI agent sells and charges in the chat

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.

Meta can limit a number that gets many reports, on the official API too. 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.
