Next year, over 420 billion emails are expected to be exchanged around the world every day. Evidently, in a world flooded with messaging apps and social media platforms, email is still a popular communication medium. Yet, as inboxes overflow, even the best-crafted emails can miss their mark if they never reach a valid recipient.
As a business, validating email addresses is essential for reaching customers effectively and supporting their journey from awareness to purchase. So, while email is a direct, convenient, and versatile marketing channel, using decayed databases hamper deliverability and outcomes. Let’s explore the pitfalls of working with defunct email addresses and how 10 industries can leverage email validation for multiple benefits.
Why Working with Obsolete Email Lists Is Costly
In business, people shift from old to new email addresses often, which means email databases degrade over time. And obsolete data in your system causes:
- Budget Leak: You spend on storing invalid email addresses and communicating with people who won’t ever receive your messages.
- Decreased Deliverability: Mailbox providers note when your emails bounce often or aren’t opened. This hampers your reputation as a sender and the probability of your future emails ending up as spam increases.
- Poor Decision-Making: Invalid or incorrect email addresses make your database unsuitable for performance tracking or campaign optimization, thereby affecting decision-making.
- Damaged Reputation: Not validating customer emails at the entry point means you cannot send updates or alerts on time. The resultant frustration can spark poor brand impression.
In short, poor-quality email data erodes campaign effectiveness, damages sender reputation, and inflates costs — all of which can be avoided with proper validation.
Data Decay: How Email Validation Addresses the Problem
Email validation helps you remove bad data (mistyped, invalid, inactive, or risky emails) from the database automatically, in real time. The absence of manual effort translates to savings in terms of time and resources.
Modern email validation tools like Melissa’s leverage syntax checks, domain verification, and mailbox ping to ensure every address in your database is real, active, and safe to send to.
Hence, by validating emails with advanced tools, you can confidently reach out to real individuals (and prospective buyers) and run marketing campaigns smoothly.
