It would be difficult to implement async/await with forEach, but it would be easy with map() because map() returns an array of promises we can Promise.all()

const userRecord = await Promise.all(recipient.map(getAuth));
const promises = userRecord.map(async data => {
  if (data.email !== '' && data.email !== undefined) {
    console.log('created');
    try {
      const sendEmail = await SES.sendRawEmail(params).promise();
      console.log('email submitted to SES', sendEmail);
    } catch (error) {
      console.log('error');
      console.error(error);
    }
  }
});
await Promise.all(promises);

Put the promises on an array, then resolve it at once.

const userRecord = await Promise.all(recipient.map(getAuth));
const sentEmails = [];
userRecord.forEach(data => {
  if (data.email !== '' && data.email !== undefined) {
      console.log('created');
        try {
          sentEmails.push[SES.sendRawEmail(params).promise()];
          console.log('email submitted to SES', sendEmail);
        } catch (error) {
          console.log('error');
          console.error(error);
        }
  }
});

Promise.all(sentEmails).then(arrayOfResults => {
  // next step
});
