5 Best Email Validator Tools You Need To Know

Are you planning a top-notch email marketing campaign for your business? Then you need a high-quality email validator. Without keeping your email list clean, it’s impossible to build an efficient email marketing strategy at a reasonable cost.

It’s hard to underestimate the importance of email marketing. Something as seemingly simple as the wrong email address could undermine the entire strategy. Without an email validator, you may face additional expenses, campaign downtime, and unhappy clients.


What is an email validator?

An email validator is a tool, which checks your email list for typos, errors, invalid addresses, and the like. By running your email list through a validator on a regular basis, you can make sure you are sending your promotional materials to your target audience.

By taking advantage of an email validator, you can forget about bounced emails, spam folders, IP blacklisting, and much more.

Real-time email validators can check the email address while it’s being typed into the contact form so the wrong address never ends up on your list in the first place.

The email validator makes sure your email list is clean before you send your first message. It can keep your domain from being flagged by Internet Service Providers or Email Service Providers, which can cause permanent damage to your reputation.

Email validators use AI, multi-layer testing, and complex algorithms to check for syntax errors. These programs can figure out how likely the email is to end up with a hard bounce. They can identify invalid email format, catch a spelling error, ensure the accurate status of every email domain, determine if the email will deliver, hard bounce or soft bounce, and report the last time a user opened the mailbox.

Failing to employ an email validator could lead to irreversible consequences. That’s why the majority of business owners take advantage of this tool.


How to choose the best email validator for your company?

Today, you can find a variety of email validators to keep your email list clean. Which one should you take advantage of? Below are several factors you need to consider before choosing a validator for your business.


1. Necessary features

What type of validator do you need? Do you want it to keep your email list clean on a regular basis or provide real-time validation? The most demanded features of a validator are:

  •         Syntax checks
  •         Bulk verification
  •         Risk assessment tools
  •         Domain confirmation
  •         Mailbox verification
  •         Formatting checks

When choosing a validator, make sure it has all the options needed for your email list to stay clean without any additional checks.


2. Cost

Of course, the cost is often a deciding factor when it comes to choosing any product or service. Email validators may have different pricing policies. Some charge per email checked, others offer monthly subscription fees.

Depending on which services you need and how many email addresses you need to check, you can choose the most convenient payment plan.


3. Trustworthy company

Since you are sharing valuable email list information with the company, you need to make sure it’s trustworthy. If you want to keep your data safe, do some research.

  • Visit the company’s website. If it’s well-designed and easy to navigate, the company cares about its clients and reputation.
  • Read reviews. If the company has at least a few reviews, you can form an opinion about it.
  • Check details. Does the company offer its address and phone numbers on the website? Do representatives pick up the phone?
  • Read the terms of service. Is your data protected when you share it? Does the company have HTTPS/SSL connections?


4. Verification time

The time it takes to validate the email list could affect your marketing campaign. Make sure to ask about the validation speed before choosing the company for your needs. Ideally, it shouldn’t take more than several minutes.


5. Customer support

Even though email verification may appear straightforward, you may still need the company to offer customer support for some of its services. Meanwhile, the validation service provider should carefully watch the security of its products and offer regular updates.

    Such a full detailed article. The interesting point of email validation services is that they must build new methods to validate email servers every day. Mail servers are creating more complex ways for message authentication and combating spam emails which makes it difficult for email verifiers to validate emails. One of these methods is anti-greylisting technology which simulates the behavior of a well-configured email server.
