Available channels: Email, SMS and WhatsApp

Last updated: August 15, 2026

We can reach your customers through three channels: Email, SMS and WhatsApp. Each notification offers the channels that suit it best, and you choose which ones to activate.

All three channels are included for every merchant, with no separate activation or contract.

WhatsApp: beyond email and SMS, you can reach your customers on WhatsApp at the three moments where a prompt response advances the operation — Renewal rejected, Renewal with cash or transfer and Card update request.

This table covers the notifications sent to your customers. The Members block contains Member invitation, which is sent by email to the people you invite to your organization.

Which channel to choose

  • Email reaches almost every notification and supports the most complete content: templates, links and receipts. It's the natural choice for anything informational.

  • SMS is plain text and concise. It arrives on the phone, which makes it effective for time-sensitive messages.

  • WhatsApp is available on three notifications, all of them moments where your customer needs to act: update a card, resolve a rejected renewal or complete a payment.

You can activate more than one channel for the same notification. Your customer receives it through each channel you enable.

Where you configure this

Go to Settings → Notifications in your dashboard. Each notification displays the channels available for it, and you decide which ones remain active. Remember to select Save to apply your changes.
