# Send Email credentials

You can use these credentials to authenticate the following nodes:

- [Send Email](/integrations/builtin/core-nodes/n8n-nodes-base.sendemail.md)

## Prerequisites

- Create an email account on a service that supports SMTP.
- Some email providers require that you enable or set up outgoing SMTP or generate an app password. Refer to your provider's documentation to see if there are other required steps.

## Supported authentication methods

- SMTP account

## Related resources

Simple Message Transfer Protocol (SMTP) is a standard protocol for sending and receiving email. Most email providers offer instructions on setting up their service with SMTP. Refer to your provider's SMTP instructions.

## Using SMTP account

To configure this credential, you'll need:

- A **User** email address
- A **Password**: This may be the user's password or an app password. Refer to the documentation for your email provider.
- The **Host**: The SMTP host address for your email provider, often formatted as `smtp.<provider>.com`. Check with your provider.
- A **Port** number: The port depends on the encryption method:
  - Port `465` for SSL/TLS (implicit encryption)
  - Port `587` for STARTTLS (explicit encryption)
  - Port `25` for no encryption (not recommended)
    Check with your email provider for their specific requirements.
- **SSL/TLS**: This toggle controls the encryption method:
  - Turn **ON** for port `465` (uses implicit SSL/TLS encryption)
  - Turn **OFF** for port `587` (uses STARTTLS explicit encryption)
  - Turn **OFF** for port `25` (no encryption)
- **Disable STARTTLS**: When SSL/TLS is disabled, the SMTP server can still try to [upgrade the TCP connection using STARTTLS](https://en.wikipedia.org/wiki/Opportunistic_TLS). Turning this on prevents that behaviour.
- **Client Host Name**: If needed by your provider, add a client host name. This name identifies the client to the server.
