A common mistake: the business picks a favorite channel and sends everything through it. Everything by email (and half of it never gets opened), or everything by WhatsApp (and it overwhelms). Each channel has a different strength, and using them well makes your messages get delivered, get read, and not annoy anyone. Here's what each one is for.
SMS: for the urgent and critical
SMS has the highest and fastest open rate of all —almost everyone reads a text within minutes— and it reaches the customer even if they don't have WhatsApp or check their email.
- Use it for: appointment reminders, confirmations, last-minute alerts.
- Don't use it for: long content or frequent promotions. Its power is that it gets read right away — don't wear it out with noise.
It's the channel that saves appointments: an SMS reminder cuts no-shows like few others.
WhatsApp: for conversation and sales
For most Latino customers, WhatsApp is where they prefer to communicate. Extremely high open rates, natural back-and-forth, personal.
- Use it for: customer support, lead qualification, closing sales, answering questions.
- Its superpower: with an AI agent, WhatsApp responds, qualifies, and books on its own, 24/7. It's your conversion channel.
Email: for long content and sequences
Email doesn't compete with WhatsApp — it covers what WhatsApp doesn't do well.
- Use it for: longer content, automated sequences (welcome, nurturing, reactivation), and messages the customer reads at their own pace.
- Its strength: it's cheap, automatable at scale, and perfect for nurturing relationships over time.

The key: everything in one place
Choosing the right channel is useless if each one lives in a separate app and conversations get lost. A CRM unifies WhatsApp, email, and SMS: every message —whatever the channel— gets logged in one place, and you automate through the right channel without jumping between apps. One customer, one history, three channels working together.
