Connect IMAP (email inbox)

  1. In Neblex open Connect › Connections and click New Connection.
  2. Search for IMAP (email inbox) and give the connection a clear name.
  3. Fill in the fields. Secret values are encrypted and never shown again.
  4. Click Test, then Create Connection.
If the system is only reachable inside your network, choose an On-Prem Worker under Test from and run the flow on that Worker. See On-Prem Workers.

Use TLSOptionalTurning this off sends traffic and credentials without transport encryption. Use plaintext only for a customer-controlled endpoint that explicitly requires it.
Connection stringRequiredSecretPaste an imaps:// connection string for implicit TLS, or imap+starttls:// for a required STARTTLS upgrade. Append ?auth=oauth2 to treat the password field as an XOAUTH2 access token. Explicit imap:// sends credentials without transport encryption and should be used only when required by a private endpoint.

Use it in a flow

  1. Open a flow, open the node library and search for IMAP (email inbox).
  2. Drag it onto the canvas and choose an Operation and your connection.
  3. Map the operation's fields from earlier steps, or click Map with Matt.
  4. Use Test this step to see what it returns, then save.

To start a flow from IMAP (email inbox) without a ready-made trigger: a Poll for changes trigger can check one of its list operations on a schedule and pass on only what is new; if IMAP (email inbox) can send webhooks, a Webhook trigger receives them at its own URL.
