As deliverability experts, we know how important a healthy email list is. It’s crucial to get emails into your recipients’ inboxes and to ensure you’re building a successful email program. That’s why we’re excited to announce a new bulk preview feature addition to our email verification service.

Why should you validate your email list?

Validating your email list is a known best practice — it weeds out risky email addresses that affect your sending reputation. Yet, not everyone does it. Why? Here at Mailgun, we’ve discovered that there are three key questions people ask when it comes to validating their email list. Let’s explore these questions and see how validation positively impacts your email program.

Does my email list need to be cleaned?

It’s estimated that 20% of your email list “goes bad” every year. This includes addresses that change, stop engaging, or unsubscribe altogether. Left unchecked, an email list that seems pretty engaged can quickly turn into a list of dead ends. To answer the first question, yes—for the best emailing results, clean your list. 

How often should I validate my email list?

Knowing when to validate your email list seems complicated. Every 3 months? Every 6 months? Depending on who you talk to, the range can vary widely. However, the answer is actually quite simple: as often as financially possible, which ties us to the third key question...

Is it worth the cost to validate my email list?

Without trying to sound overly philosophical, what is the value of a clean list? Often, unengaged and unresponsive email addresses drive down your open and click-through rates, which hurt your email program’s engagement metrics and lessen consumer interest. In today’s world, email is a vital marketing tool. Ensuring that you have a clean list of engaged, interested customers helps you deliver your messages directly to those who are interested in your products and services.

So, here comes the big question–how can you assess and improve the health of your email list quickly and easily AND without financial risk? 

Announcing Mailgun’s new bulk preview feature
