Email Overview
Connecting Email
When using the respond.io platform for email messaging, it's important to understand what email is and how it works. Email is short for electronic mail and is a way for users to exchange information over telecommunications. This can include text, files, images, or other attachments that are sent through a network to a specified individual or group of individuals.
Message Status Availability
The message status availability for different Email Channels is shown in the table below:

Supported File Types
Google Workspace supports images with a maximum file size of 10 MB.
Metadata Received by Channel
Different channels provide different sets of Contact's metadata to the respond.io platform. The list of Contact's data you’ll be able to obtain from different Email channels is shown the table below:

Text Formatting
For email channels, the platform provides a rich text editor in the message composer to assist you in formatting your message by making text bold, underlining it, embedding links, adjusting alignment, changing color, and more.
Channel Limitations
Email Channels have a distinctive communication style that differs from messaging Channels. In particular, content style in email is typically expected to be more formal, long, and slow compared to instant messaging Channels, which tend to be short, casual, and quick. Therefore, when using the email Channels on the respond.io messaging platform, there are certain limitations that users should be aware of.
- Email broadcasting is not supported on respond.io as the broadcast module is designed for sending broadcasts over messaging Channels. Email broadcast has a different infrastructure as well as requirements and rules to avoid domain being flagged. Thus, consider using messaging Channels for broadcasts.
- Dialogflow's chatbot is not supported for email Channels on respond.io due to Dialogflow's intent text input limit. For more advanced and user-friendly automated replies to conversations, consider using Workflows.
- When using the Ask a Question step in Workflows, you may experience some limitations such as a new email thread you created will have a blank subject and each question you ask will be sent as a separate email instead of in a single email thread. This is because email and the Ask a Question step feature are not compatible technically. We do not recommend using the Ask a Question step with the email channel.
