New Email on IMAP

Description:Emit new event for each new email in a mailbox

IMAP Overview#

Using Pipedream's IMAP API, developers can automate interactions with their email inbox, enabling serverless workflows that perform actions based on incoming emails. This could include parsing email contents, triggering events upon receiving emails from specific senders, attaching labels, and much more. By leveraging IMAP, Pipedream can act as a bridge between your email and other services, streamlining processes that would otherwise require manual intervention.

Trigger Configuration#

This component may be configured based on the props defined in the component code. Pipedream automatically prompts for input values in the UI and CLI.

Label	Prop	Type	Description
IMAP	`imap`	`app`	This component uses the IMAP app.
N/A	`db`	`$.service.db`	This component uses `$.service.db` to maintain state between executions.

IMAP uses API keys for authentication. When you connect your IMAP account, Pipedream securely stores the keys so you can easily authenticate to IMAP APIs in both code and no-code steps.

Below are the required fields to connect your IMAP account to Pipedream:

host: Enter the host Pipedream should connect to. Refer to your email provider's IMAP instructions if you aren't sure what to enter.
email: Enter the email address you use to sign in to the account you'd like to connect.
password: This is the password you use to sign in to your email account. Note: in order to connect a Gmail account, you must use an App Password.
port: Specify the port number, either 143 (default) or 993. Refer to your email provider's IMAP instructions if you aren't sure which to use.

For Gmail accounts, refer to these instructions.
