# Use Send Time Optimization

## Overview

We’ve all been there: the carefully crafted email lands with a thud, the SMS gets buried under a notification avalanche, and the WhatsApp message sits unread in a sea of group chats. But what if there was a way to ensure your important messages get seen and acted upon? Enter the magic of Send Time Optimization (STO).

STO is like a personal assistant for your communication channels, analyzing user behavior data to predict the golden hour when they’re most likely to engage with your message. Whether it’s an email promotion, an important SMS alert, or a friendly WhatsApp reminder, sending it at the right time can significantly boost open rates, click-throughs, and overall engagement.

## How it Works

{% tabs %}
{% tab title="Email" %}
Imagine your emails landing in inboxes at 8 AM on a Monday morning, competing with a tsunami of work emails. Not ideal. STO analyses past open rates and engagement patterns to send each email at the recipient’s preferred viewing time, be it during their lunch break or evening wind-down.
{% endtab %}

{% tab title="SMS" %}
The immediacy of SMS requires a different approach. STO considers factors like past response times, location, and even time zones to ensure your message arrives when the recipient is most likely to have their phone handy and be receptive.
{% endtab %}

{% tab title="WhatsApp" %}
Unlike emails, WhatsApp messages often get lost in the constant flow of conversations. STO takes advantage of individual activity patterns to identify the moments when users are most active, maximizing the chances your message gets seen and responded to.
