5 Important Reasons to Validate Your Email Lists

Rebecca Felker

We learned in Part 1 of the blog series about what email verification is and how it works. In part 2 of this blog series, let’s talk about why email validation is so important to your email marketing efforts and to your brand.

Email verification is a process that cleans your email list to verify the email addresses you’re sending to exist, are active and are accepting mail. Typically, this service is provided as online software as a service. And this is where ZeroBounce comes in – the email validation system to validate email lists, improve deliverability, and in-turn improve your sender reputation.

Here are 5 reasons why you should use an email validation service:

1. Protect sender score

A sender score is a number based on the reputation of every outgoing mail server IP address (the higher the number, the better the score). The credibility of your IPs and domains are attributed to your ISPs and spam filters. If people report spam or frequently unsubscribe, both of these actions will affect your sender score. If you are using a service like ZeroBounce to validate your email list, it will remove invalid emails, spam traps and known email complainers from our list and help protect your sender reputation. Protecting your sender score through email validation will help to improve your email deliverability and campaign success.

2. Increase deliverability

The average inbox placement rate, in all industries is 85%. By managing bounce rates and complaints, more of your messages will make it to the inbox of your customers; therefore increasing your deliverability rate. This will result in higher open, click and response rates.

3. Reduce bounce rate

The percentage of sent messages that cannot be delivered represents bounce rate. According to data from Campaigner, larger lists experience lower bounce rates. If you look at the average bounce rate with a list size of 25-499 the bounce rate is 2%. For a list size of 500-999, the bounce rate is 1.6 and for 1000 or more, the bounce rate is 1.2%. Anything above 2% is something to be aware of. Using email validation to clean out undeliverable email addresses means a larger percentage of emails sent will be delivered, in turn lowering your bounce rate.

4. Save money

The larger your list gets, the more likely you are to have invalid email addresses on it. In a study performed by SiriusDecisions, they found that 10% to 25% of customer and prospect data contained inaccuracies. Since every message sent serves as a dollar spent, removing bad email addresses from your list will lower your sending costs and in turn send to a more current email list.

5. Protect against fraud

Email validation can help combat against fraud. Spam trap emails look like real email addresses, but they are fake. If you inadvertently send email to a spam trap, the impact can be disastrous with consequences ranging from making your sender reputation plummet to permanently blacklisting your sending domain.

Now that we have an understanding of why email validation is key to deliverability and sender reputation, in part 3 of the blog series we’ll talk about how ZeroBounce can help remedy these issues. And in case you missed part 1 of this blog series, check it out here.
