In short, the online verifier investigates the domain name, and legitimacy of the input addresses. Then, you can identify the reliability of each of the addresses on the contact list. Thus, you find categories such as safe to send, disposable, invalid, role-based( [email protected]), and so on.

Now, that you hold the power of knowledge, you can reassess your mailing contacts. There are mainly 3 steps that online verifiers act upon:

Syntax Check

When designing your professional email content, you want correct spelling, grammar, and punctuation. In most cases, writing tools like Grammarly help you create the perfect outline. Similarly, syntax check algorithms ensure the same correctness in terms of email information.

The syntax check assures standard correspondence, the accuracy of (@) symbols, dot-symbols, and any other such detail. Alongside, it checks the accuracy of special characters and symbols.

Domain Check

As you might have noticed, the domain name is found right after the “at the rate” (@) symbol. The purpose is to indicate which domain the email is attached to. For instance, [email protected], where outward is the domain name. Online verifiers cross-reference the spelling of the domain name, as well as its authenticity and activity status.

Now you might wonder, why do I need a domain check? Well, because no one works at one place for their entire lives. Or they might not use the same email address anymore. Websites may not exist anymore, thus, making the tied-up email address invalid. Companies may also switch their hustle, migrating to new domains. Thus, with a simple check, you can vastly boost your deliverability rates.

Email Address Ping

Also known as SMTP authentication, email address ping is an important aspect. It authenticates the active status and safety of email addresses. The online email verifier pings the given address( or sends a signal). Subsequently, it checks if the email is actually receiving the message and responding to it. If the request has reached the address, the email marks itself as real and safe for exchanges.

Breaking Misconceptions

More often than not, the hunt for online verifier tools brings a distaste towards the service. However, what often surrounds such encounters are misconceptions, that we aim to break:

1. Email Lists Do Not Require Regular Cleaning

Far from the truth, this controversy of time is pretty common. First of all, regularity is a subjective matter. How often you verify your campaign prospects, is completely up to you.

Since verification is almost mandatory before you start any new campaigns, there is no preset time period of regularity. However, keeping a tab on the strategies turnout is important. The reach and growth of your marketing campaign determine the frequency of verification. In any case, the greater the number of malfunctioning emails, the higher the cost of your investments. Hence, design your time frame in accordance.

2. No Bounces, No Verification Required

Though the notion of zero bounce rate is great news, it does not determine the end of your verification process. This is because bounce rate control is solely a part of the whole process, online email verifiers perform multiple other functions simultaneously. By believing in this misconception, you are leading your campaign to suffer from poor deliverability rates and the sender’s reputation

3. Very Expensive

Quite the contrary actually. The hidden cost of failed deliveries, poor lead generation prospects, and collapsing sender reputation is a greater expense. And deep cleaning email lists even regularly is not extremely expensive. For instance, VerifyBee lets you verify 2500 emails for $19 only! Plus, they have various other price bundles to follow as well.

Final Thoughts

By reducing the cost of failed deliverability and ensuring lower bounce rates, you are saving $20 every day with a cleaned email list.

This is something you can expect when done right. And if you are looking for platforms, that are simple to use, but highly encouraging in results, we have VerifyBee for you. Remember, it's pay-as-you-go, so nothing to lose right?
