AWS Billing Alerts: Send email and trigger Lambda function

What I'm trying to implement is that on the AWS billing alarm I want to send an email and invoke a lambda function written in python from where I want to update something in the database. So how can I get these both, I know that against alarm you can send an email to the user but how to do both when an alarm is triggered?

            }

}

When configuring an Amazon CloudWatch alarm, you can specify an Amazon Simple Notification Service (SNS) topic. Messages relating to the alarm will be sent to this topic.

Amazon SNS is a 'publish-subscribe' model, meaning that recipients need to subscribe to the topic to receive a notification. Subscription types include:

• Email
• AWS Lambda functions

All subscribers to a topic will receive messages sent to the topic.

When a subscribed AWS Lambda function receives a message from an SNS topic, it is provided with details of the alarm that triggered the message. You can use this information to store relevant data in the database.
