Reply to Gmail emails within a threaded conversation
This block fits into workflows that involve automated email communication, such as responding to support inquiries, sending follow-ups based on AI-generated content, or routing replies through conditional logic. Because it threads replies under the original message, it is suited for workflows where conversation continuity in Gmail is important.
What you can build
Real-world workflows powered by the [Gmail] Reply to Email block.
Automated Support Replies
When a support ticket arrives via Gmail, an AI block generates a response and this block sends it as a threaded reply to the original message.
Lead Follow-Up Emails
After a prospect emails a sales inbox, a workflow generates a personalized follow-up and replies directly in the same Gmail thread.
AI-Drafted Email Responses
An AI model drafts a reply based on the content of an incoming email, and this block sends the draft as a threaded Gmail reply.
Approval Workflow Notifications
When an internal approval request is processed, the workflow replies to the original email thread with the approval status.
Scheduled Email Follow-Ups
A workflow monitors unanswered emails and sends a follow-up reply in the original thread after a defined time period.
HTML Newsletter Replies
A workflow replies to inbound email inquiries with a formatted HTML message, using the messageType field set to 'html' for rich content.

What parameters are required to use this block?
The block requires a messageId (the Gmail message ID of the email to reply to), a message (the body content of the reply), and a messageType specifying the format of the body — either 'plain', 'html', or 'markdown'. A connectionId for the Google OAuth connection is optional but needed to specify which Gmail account to use.
What does the block return after sending a reply?
The block returns a single output field: messageId, which is the Gmail message ID of the sent reply. This can be used in downstream workflow steps for logging, referencing, or chaining additional actions.
How is the reply threaded in Gmail?
The reply is threaded under the original message identified by the provided messageId, keeping the conversation grouped in Gmail as a single thread.
What message formats does the body support?
The messageType field accepts three values: 'plain' for plain text, 'html' for HTML-formatted content, and 'markdown' for Markdown-formatted content. This controls how Gmail renders the reply body.
What kinds of workflows commonly use this block?
This block is commonly used in automated email response workflows, customer support pipelines, lead follow-up sequences, and approval notification systems — any workflow where a reply needs to be sent within an existing Gmail thread.
