Email not recieved after attempting to send through SES via Lambda

I've been trying to send email through SES, however i was unable to receive the email. When the function is run it does return a response instead of an error:

{
  "ResponseMetadata": {
    "RequestId": "e88074e6-8316-464d-98fa-5407b4fc4652"
  },
  "MessageId": "0100017ed4cc35ac-514b6cf0-2eee-4246-baf6-a75c1dfb3cd8-000000"
}

But the atual email doesn't seem to be sent. I've made sure the email is varified and is outside of the sandbox. The code looks as follows:

  var params = {
    Destination: {
      ToAddresses: ["Sender's Email", 'Another Varified Email', 'Non Verified email']
    },
    Message: {
      Body: {
        Text: {
          Charset: "UTF-8",
          Data: "Test"
        },
      },
      Subject: {
        Charset: "UTF-8",
        Data: "Test email"
      }

    },
    Source: "Sender's Email",
  };

  await SES.sendEmail(params).promise().then(data => { callback(null, data) }).catch(err => callback(err))

I've also checked the cloud watch, it is reflecting as if I've send those emails. Just at the end I've not received any email I've supposedly sent out both through SES test, and the lambda function above.
