Email bounces are a problem for all email marketers and applications that send email. How do you prevent email bounce back effectively and protect your email spam ranking?

What are email bounces?

Email bounces occur when a mailserver sends an email to another server, who then rejects the messages and sends it back to the original sender with a rejection message.

Preventing bounces (keeping email lists clean)

Verifying emails on your marketing campaign lists is the key way to reduce bounce rates. Use services like MailSlurp's free email validator to filter email lists for valid email addresses only.

Verify email addresses in code

Use the MailSlurp javascript email client to verify email address lists in code:

const mailslurp = new MailSlurp(config);
const res =
  await mailslurp.emailVerificationController.validateEmailAddressList({
    validateEmailAddressListOptions: {
      emailAddressList: ['contact@mailslurp.dev', 'bad@mailslurp.dev'],
    },
  });
expect(res.resultMapEmailAddressIsValid['contact@mailslurp.dev']).toEqual(
  true
);
expect(res.resultMapEmailAddressIsValid['bad@mailslurp.dev']).toEqual(
  false
);
