The importance of email ID validation
Stop bad emails from ruining your sender reputation with email ID validation
What’s the easiest way to tank your email marketing program? Bad data.
The best responsive email designs, exciting subject lines, cool color scheme, and snappy copy won’t save an email marketing campaign that’s built with invalid email addresses.
Sure, the occasional hard bounce will happen with every send. But the higher your bounce rate, the more likely your sender reputation is at risk. That’s because major inbox providers watch for spammy behavior – including sending to invalid email addresses.
Stop bad email addresses before they ruin your email list. When someone signs up for your list, Mailgun’s email ID validation service double and triple-checks that you’re adding a real person to your list.
What's an invalid email address?
An invalid email address is either improperly formatted or just doesn’t exist. A valid email address, of course, is one that’s properly formatted and does exist. Sometimes the difference is just a matter of filling out a form incorrectly (hey, it happens to the best of us!)
Let’s look at five examples of valid email addresses:
email@domain.com
firstname.lastname@domain.com
email@subdomain.domain.com
email@domain-one.com
firstname-lastname@domain.com
Now, here are five examples of invalid email addresses:
@domain.com (missing username)
email.domain.com (missing @)
email.@domain.com (leading dot is not permitted)
email@domain (missing top-level domain like .com or .net)
email@-domain.com (leading dash in front of domain is invalid)
These are simple email ID mistakes that can easily be avoided when you verify email addresses with an email checker directly within your email forms.
Why every great email marketer needs email ID verification
One-fifth of legitimate business emails never appear in the targeted inbox. All that time spent on acquisition, lead generation, email marketing design and execution...gone in an instant.
Using an email validator, you can build an email list free of invalid email addresses and have a better chance of being in the 80%.
When Email Validation verifies an email address actually exists, you won’t waste money sending to temporary or disposable mailboxes, role-based email addresses (like info@), or bad email formats. Over time, this protects the reputation of your domain and IP address, reduces bounces, and offers a higher delivery rate.
