How to send multiple emails using Amazon SQS and SNS?

In my JAVA application, I am using Amazon SQS and SNS; I am doing the
below steps:
Step 1: I am pushing the message to SQS like,
SendMessageResult aSendMessageStatus = Amazon_SQS_Client.sendMessage(new
SendMessageRequest().withQueueUrl(AWS_SQS_URL).withMessageBody(theRequestString));
Step 2: Created topic in SNS like,
CreateTopicResult createRes = Amazon_SNS_Client.createTopic(createReq);
Step 3: I am trying to send email by receiving the messages from SQS to
100 of customer.
Can someone advice me on how to subscribe the topic in SNS and send the
emails to multiple email addresses.
