What Is An Email Verification Tool?

It is a software or a SaaS application that helps you determine the validity of an email address. In simple terms, email verification software will tell you if the email exists or not.

Apart from determining if the email address exits, it also helps you find out spam traps and malicious email addresses. In addition to this, email verifiers help email marketers reduce bounce rates by checking the deliverability of email addresses and ultimately keeping email lists clean.

Types Of Email Verification

With the current technological advancement, most users prefer online or SaaS email verifiers. They are simple but robust enough to handle all kinds of email validation needs.

Not to forget but you can access these tools from anywhere. You simply need your laptop or a computer device with an internet connection.

That being said, email verification tools offer two modes to clean your email lists –

  • Real-time verification via API
  • Bulk email verification

Real-time Email Verification

This mode of email verification usually involves you integrating your software, SaaS application, or email marketing service with the email verifier. Once integrated, the email verifier API will verify your email lists in real-time and remove all invalid email addresses.

To help you better understand this method, let’s assume you have a SaaS application with a sign-up form with an integrated email verification API at the backend. In the sign-up form, once the user enters his email address, the API will identify if the entered email address is valid or not.

Similarly, when you integrate it with ESPs, the email verifier will clean your email list in the ESP itself.

Bulk Email Verification

The bulk email verification is usually carried out in the email verifier dashboard. In this mode, you can either copy-paste email addresses or upload a file containing email addresses.

Once uploaded, the email verifier will perform various checks and removes invalid email addresses from your list.

Later, you will also have the option to download your verified email lists in different file formats.

How Do Email Verification & Validation Work?

After importing or uploading your email lists, all email verification tools pass it through a set of different verification processes.

Yes, it is important to point out that every email validation service has its own proprietary algorithm for verifying emails. This also weighs up in the accuracy level achieved while cleaning an email list.

Besides these, there are some common parameters like email deduplication. In this process, all the duplicate email addresses are automatically removed from the email list. Furthermore, it also performs syntax checks where the email verifier checks if the syntax of email addresses is correct and does not contain any typos.

Next, the email validator performs checks for temporary or disposable email addresses. These types of email addresses belong to free mail servers and have a lifespan of merely a few days.

The tools then perform domain checks wherein the email addresses belonging to inactive, invalid, parked, and bad domains are removed.

Lastly, almost all the email verification tools perform real-time SMTP handshakes with the email addresses to determine their validity status.

Benefits Of Using An Email Verification Software

Here are some of the most notable ways in which an email validation software will benefit you –

  • Cleans Your Email Lists – The primary benefit of using an email verifier is to remove all the invalid, bad, and dead email addresses from your email lists. When done manually, it could take days or even months while these tools do it in just a few minutes.
  • Reduces Bounce Rates – With the invalid and expired email addresses removed from your lists, your email campaigns are less likely to bounce.
  • Maintains & Boosts Sender Reputation – Since your email campaigns are less likely to bounce, you get to maintain a high sender reputation.
  • Improves Email Deliverability – After achieving a high sender reputation, your email campaigns are bound to reach the inbox of your recipients. Hence, email verifiers ensure that you get better email deliverability.
  • Helps In Achieving Higher ROI – With high email deliverability and low bounce rates, your emails will land in the inbox of your subscribers. This ensures that you get better engagement and conversion rates from your campaigns.
  • Saves Money – Most email marketing services have a pricing model based on the number of contacts in your email lists. After removing invalid emails, the count of contacts’ email addresses will be reduced. This would ensure that you have to subscribe to a lower pricing plan.

Factors To Consider While Choosing The Best Email Verification Service

There are numerous email verification tools available in the digital market. It would be difficult for a new user to pick the best among them.

So here’s a checklist of factors that you need to look for while choosing the ideal email validator –

  1. Robust Verification Processes – You must check what verification processes your software employs. Some of the most used measures are syntax checks, deduplication, disposable email removal, SMTP pings, etc.
  2. Email Verification Accuracy – Based on the email verification processes, the email verification software must offer 95-99% accuracy. If you find anything less than this, it would be better for you to consider other verifiers.

  4. Multiple Use Cases – The software must allow you to clean single as well as bulk email addresses. It should also offer a dashboard to upload and download email lists with customizable options.
  5. Integration Options – It would be beneficial for you if the email verifier comes with API or direct integration options with email marketing services, CRMs, etc. Not to forget but the API of the software can also be used to integrate with your SaaS’s sign-up form.
  6. Customer Support – The tool should be supported by a prompt and knowledgeable customer support team. Since email verification is a technical process, the customer support team should be able to answer your queries.
  7. Pricing – The email verification tools be affordable and should come with different pricing models. For users with one-time email verification needs, the software should offer pay-as-you-go plans. At the same time, for users with frequent email verification needs, subscription plans would be ideal.
