Almost every adult has an email address. This makes it one of the most effective means of communication between companies and their customers. 50% of all media planners use email marketing. And, why not, email marketing is budget friendly and offers an impressive $36 ROI against every $1 spent.

There are many ways companies build an email database – surveys, free eBook downloads, tutorials, newsletters, contests and so on. Some companies even buy email databases. Data collection is easy, the real challenge lies in verifying emails. No company wants email addresses like john@gmail,com or in their database. Neither do they want to be sending emails to invalid or out-of-use email addresses.

The most efficient way to keep a clean email database is by using real-time email verification APIs.

What Are Real-Time Email Verification APIs?

These verification tools instantly check email addresses entered into a form against reliable third-party databases to validate them. They check that the email addresses are valid, formatted in the correct syntax and linked to the right person. Simple domain name typo errors and syntax errors can be corrected on the spot to maintain email list hygiene. These APIs also keep disposable email addresses out of the database and minimize the risk of fake registrations.

Benefits Of Verifying Emails

Working with a verified mailing list offers many benefits.

  • Protects Your Sender Reputation

Sending emails to invalid email addresses puts you at the risk of a higher bounce rate. If this crosses a certain threshold, there’s a high chance of your domain being blacklisted. This would keep you from sending out email campaigns in the future and Categorizes Your Emails As Spam.

Verifying mailing lists before you send out emails protects your sender reputation and lowers the risk of having emails bounce back.

  • Improves Response Rates

Relying on verified emails increases your email open rate. You’re also more likely to get a response from customers. This opens up business opportunities and maximizes the potential for marketing opportunities.

  • Optimizes Campaign Costs

When you eliminate invalid emails, you may be sending out fewer emails but you’re assured that these emails will reach the intended recipient. Thus, the resources you have will be used to their full potential. This offers you the best ROI.

  • Makes Email Marketing Analysis More Reliable

Let’s say you send out 100 emails and get responses only from 20 recipients. This would give you a 20% response rate. But, what if only 80 emails were valid and you were successfully able to identify and eliminate rest 20 invalid email IDs. Emails now will be delivered only to 80 valid ones. Your response rate would then increase to 25%. Thus, working with verified emails makes your campaign metrics and analysis more reliable. In turn, this helps build confidence in data and inspires your team to make data-driven decisions.

Email Verification Use Cases

Let’s look at a few instances when email verification APIs can be used.

  • Customer Onboarding Forms

Customers often make typographic errors when creating an account with a new website. Studies show that 0.06% of commercial email is directed to typo domains like or because of typographic errors. These errors can be avoided by using email verification tools.

  • Newsletter Subscription Forms

If you collect emails by giving customers and site visitors the option of signing up for newsletters or product launch notifications, using an email verification API ensures that you include only valid, verified emails in your database.

  • Online Order Placement

Entering an email address is a must for customers placing online orders. Even if customers aren’t creating an account, they need to enter their email addresses. This email will be used for order confirmation and messaging about delivery timelines as well as for future marketing communication. Verifying emails at this stage ensures that the company can communicate easily with their customer.

Choosing the right email verification API

There are a number of email verification tools available today. Hence, it is important to choose the right tool. Look for an API that can verify email addresses by pinging the email. Expecting a customer to click on a link in an email to verify the existence of an email isn’t always the best idea.

It should also be able to check the email address against reliable third-party databases to ensure deliverability and maintain CAN-SPAM compliance. And it should also be able to correct simple typographic errors, remove illegal characters and standardize casing and syntax.

In addition to verifying email addresses at the time they enter the database, you should also ensure that the verification tool you choose can regularly check emails in your existing database. This is important because when people switch email mailbox providers, they don’t necessarily update their details on business accounts. An email database can decay at the rate of 22.5% annually!

Businesses in all industries can benefit from using real-time email verification. It’s time you start verifying the emails in your customer database.
