The Secret to Email Performance - Data Quality Tactics

Feb 25, 2025

Imagine sending out invitations for a grand event, but half the addresses are wrong. You would end up wasting your efforts, and your guests would never arrive.

That is basically what happens when, in email marketing, one neglects to take care of data quality.

Email performance, therefore, is defined as the extent to which your emails successfully engage recipients, solicit sufficient responses, and, in turn, help you attain your marketing goals. Email success is measured by open rates, click-through rates and conversion rates, and poor quality of data can be a sure killer for the latter.

So, what strategies guarantee your emails will get to the right people and get the results you need?

Let us go through data-driven strategies enhancing email performance and contributing to better engagement, conversion, and deliverability improvement.

Email Verification:

We all have a habit of checking the mail a lot to ensure there are no errors. Like that before you hit "send," make sure that your emails reach real people. This can eliminate fake, inactive, or mistyped emails from your list in order to minimize hard bounces and create a favorable impression on the sender's reputation.

“Your email list is your biggest asset. Treat it with care.” — Neil Patel, Digital Marketing Expert

Let's make it in scenario

A company that sends out weekly newsletters saw a sudden slump in engagement. In their investigations, it was found that due to invalid email addresses, they had a 30% bounce rate. On implementing an email verification tool, the open rates improved by 20%.

List Cleaning: Quality Comes Before Quantity

You have a great big list of emails, but if half of those contacts never engage, their time for cleanup is now! The act of list cleaning includes getting rid of old or inactive subscribers in order to achieve better targeting and higher engagement.

“A small, engaged list is better than a large, indifferent one.” — Rand Fishkin, Moz Founder

Ways to Clean Your List:

Sweeping out inactive subscribers after they have sat quiet for six months.

Engage those contacts in re engagement campaigns before letting them go.

Make separate lists of users according to their past actions.

Campaign Optimization: Data-Driven Decision Making

Optimization of the campaign means not guessing, but using data to perfect subject lines, content, and sending times. Track email metrics like open rates, CTR, and bounce rates to determine a course of action.

For instance,

One e-commerce brand discovered that Tuesday sending emails boasted an engagement rate that was 40% higher than their engagement rate for Friday-sent emails. After moving their timing, there was a 15% increase in conversions.

Deliverability improvement: Get across the spam filters

A good approach to engaging interests would, of course, stand no chance if it finally makes it into spam. There are several ways to guarantee that your emails make the inbox:

Use a reputable email service provider.

Avoid spam words, like "free money" or "urgent offer."

Example:

After struggling with email engagement, this startup found a missing piece-their domain did not have proper authentication set up. Once DKIM and DMARC were set up, the placement in inboxes increased by 25%.

Customer Insights: Personalization That Works

People tend to ignore generic messages. Leveraging the offer of data helps target each person with solid-aimed dispatches.

“The best marketing doesn’t feel like marketing.” — Tom Fishburne, Marketoonist

What's the Use of Customer Data?

Suggest products based on previous offers made to customers.

Send birthday or anniversary emails.

Customize subject lines to guarantee better access.

Digital Optimization: Keeping Up With Trends
