# Function to send emails using Oracle Cloud Infrastructure Email Delivery
Function to send emails with [Oracle Cloud Infrastructure Email Delivery](https://docs.cloud.oracle.com/iaas/Content/Email/Concepts/overview.htm). It just uses the plain old [SMTP package in Go](https://golang.org/pkg/net/smtp/)
## Pre-requisites
### Configure OCI Email Delivery
- [Generate SMTP Credentials for a User](https://docs.cloud.oracle.com/iaas/Content/Email/Tasks/generatesmtpcredentials.htm) - you'll have to configure these user credentials in the app (`OCI_EMAIL_DELIVERY_USER_OCID` and `OCI_EMAIL_DELIVERY_USER_PASSWORD` variables)
- [Add approved sender](https://docs.cloud.oracle.com/iaas/Content/Email/Tasks/managingapprovedsenders.htm) - use `OCI_EMAIL_DELIVERY_APPROVED_SENDER` parameter to configure this in the app
- [Note down value for the SMTP server](https://docs.cloud.oracle.com/iaas/Content/Email/Tasks/configuresmtpconnection.htm) - it'll be used in the `OCI_EMAIL_DELIVERY_SMTP_SERVER` configuration attribute

### Switch to correct context
- `fn use context `
- Check using `fn ls apps`
### Create app
`fn create app --annotation oracle.com/oci/subnetIds= --config OCI_EMAIL_DELIVERY_USER_OCID= --config OCI_EMAIL_DELIVERY_USER_PASSWORD= --config REGION= --config OCI_EMAIL_DELIVERY_SMTP_SERVER= --config OCI_EMAIL_DELIVERY_APPROVED_SENDER= fn-email-app`
e.g.
`fn create app --annotation oracle.com/oci/subnetIds='["ocid1.subnet.oc1.phx.aaaaaaaaghmsma7mpqhqdhbgnby25u2zo4wqlrrcskvu7jg56dryxt3hgvkz"]' --config OCI_EMAIL_DELIVERY_USER_OCID=ocid1.user.oc1..aaaaaaaa4seqx6jeyma46ldy4cbuv42q4l26scz5p4rkz3rauuoioo42qwmq@ocid1.tenancy.oc1..aaaaaaaaydrjm77otncda2xn7qtv7l3hqnd3zxn2u6siwdhniibwfv4wwhta.3n.com --config OCI_EMAIL_DELIVERY_USER_PASSWORD='s3cr3t:-)' --config OCI_EMAIL_DELIVERY_SMTP_SERVER=smtp.us-phoenix-1.oraclecloud.com --config OCI_EMAIL_DELIVERY_APPROVED_SENDER=test@test.com fn-email-app`
**Check**
`fn inspect app fn-email-app`
## Moving on...
Deploy the app...
`cd fn-email-app` and `fn -v deploy --app fn-email-app`
Test it out
> change the email contents as per your requirements (*don't forget to provide a valid email address*)
`echo -n '{"To": "test@gmail.com", "Subject": "Hello from Fn", "Body": "Have fun with Fn at fnproject.io"}' | fn invoke fn-email-app sendemail`
If all goes well, you should see the email (*don't forget to check your spam folder*) and a response from the function - `Sent email successfully!`
