# Share Blocks
## Overview
The share blocks allow your app's users to distribute content or information from the app across different platforms or communication channels. These blocks enable users to easily share text, images, or links via messaging apps, social media, emails, or other sharing options available on their device.
## Text to Phone Number
The "text to phone number" block opens the device's default text messaging app and populates the text message's content and phone number. It will not send a text message without the app user's knowledge.
## Send Email To
The "send email to" block opens the device's default email app with an email and populates the subject, message body, and email address. It will not send an email without the app user's knowledge.
You can email multiple recipients by separating the unique email addresses with a comma in the block's 'send email to' section.
{% hint style="info" %}
For iOS, you can use HTML formatting to customize the emails you send with the share blocks.
{% endhint %}
## Call Phone Number

## Share Message

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:
```
GET https://docs.thunkable.com/blocks/app-features/share.md?ask=&goal=
```
`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.
The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.
Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
