可以使用AWS SDK for Python（Boto3）将电子邮件发送到SNS主题。

以下是示例代码：

import boto3

# Create an SNS client
sns = boto3.client('sns')

# Create a topic with name 'MyTopic'
response = sns.create_topic(Name='MyTopic')

# Get the topic ARN (Amazon Resource Name)
topic_arn = response['TopicArn']

# Subscribe an email address to the topic
response = sns.subscribe(
    TopicArn=topic_arn,
    Protocol='email',
    Endpoint='email@example.com'
)

# Print out the subscription ARN
print(response['SubscriptionArn'])

# Send an email to the topic with subscriptions pending confirmation
response = sns.publish(
    TopicArn=topic_arn,
    Message='Hello World!',
    Subject='Test message'
)

# Print out the message ID
print(response['MessageId'])

使用此代码，您可以创建一个名为“MyTopic”的主题并将电子邮件地址“email@example.com”订阅到该主题。然后，您可以使用“sns.publish”方法向主题发送电子邮件。如果有等待确认的订阅，电子邮件将发送到这些地址以进行确认。
