How Bounced Emails Affect Your Bottom Line

Bounced emails do more than just prevent your message from reaching recipients — they also impair your company’s sender’s reputation. This damaged reputation impacts your email deliverability, or your percentage of successfully delivered emails. A bounce rate of above 5% will negatively affect your email campaign’s success as well as that of future campaigns. That’s because email networks monitor a sender’s bounce-back trends to determine whether they will accept their emails. The fewer emails that reach your recipients’ inboxes, the less chance they have of being opened.

How To Verify If Email Addresses In Your List Are Valid

Verifying valid email addresses ensures that your email campaigns reach their
intended recipients. Without recipient validation, your emails may end up in
receivers’ spam folders. You can verify email validity in various ways:

Validate syntax

You can evaluate the local and domain parts of each email to verify that the syntax is valid. The local part of the address may contain alphanumeric characters, printable characters, and a dot, while the domain may contain alphanumeric characters and a hyphen.

Check for typos

A message won’t send if the recipient’s email address includes any typos. Scan your email list to pinpoint common typographical errors.

Look for disposable emails

Disposable emails are temporary addresses that are only valid for a designated amount of time. Look out for email addresses generated by services like Mailinator and Nada to eliminate disposable emails.

Perform a DNS lookup

Domain Name System (DNS) lookups allow you to request a DNS record from the DNS server. You can use a DNS lookup to generate a mail exchange (MX) record, which identifies a domain name email server and enables you to choose one with the highest priority.

Ping the SMTP server

After performing a DNS lookup, you can connect to the Simple Mail Transfer Protocol (SMTP) server to query whether a recipient address exists. A server response of “250 OK” indicates that the address is valid, while negative responses indicate that it does not exist.

Send a test email

You can verify valid email addresses by sending a test email and observing whether it bounces or delivers. However, this process can be tedious and time-consuming.
