What is email verification and How to choose the best Email Verifier

Updated on August 20, 2021 by Igor

Making a lead list for an email outreach campaign is a process that not only consists of finding email addresses. You have to check the emails you have before you start sending them. If you are facing delivery problems, the email address you are trying to contact may be invalid or the company you are reaching out to has set up a catch-all email. Therefore, your bounce rate will be negatively affected. That is where email verification comes into play.

In this article, we will explain what is email verification, how email verification works, why and how you should use it.

What is email verification?

Email verification is the process of verifying the existence of an email address and that is currently in active use. Meaning it can send and receive messages and is tied to a legitimate domain. (There is also a high possibility a person is behind it and will receive your messages 😉 ).

Email validation status represents the status of an email address, valid or invalid.

Valid – the email address is verified and in current use

Accept-all – the email address is not a catch-all address (messages sent to a nonexistent or mistyped email address on the target domain will be sent to this type of address, but will result in a bounced message)

Invalid – the email address is not verified and a sent email will result in a bounce

How email verification works

The email verification system depends on the platform. Overall there are several algorithms and overlapping systems checks in place to ensure a better validation model with a higher percentage of accuracy. The Sales.Rocks email verifier uses the following email verification system to provide the most accurate results and ensure optimal email delivery.

There are 7 steps of the email verification process:

  • Syntax checker
  • Gibberish checker
  • Domain checker
  • Throwaway email checker
  • MX record checker
  • SMTP Authentication checker
  • Accept-all checker

Syntax check

The format of the email address, which should contain two parts separated by the at-sign “@”, the local part, and the domain part. It also checks for common syntax mistakes.

“user@sales.rocks”

user – local part
@ – at-sign
sales.rocks domain part

According to internet regulations, an email address must follow these guidelines:

The local part can contain 64 characters at the most

The ( . ) and the ( @ ) symbol are in the correct place

Special characters as: ! # $ % & ‘ * + – / = ? ^ _ ` . { | } ~ can be used in the local part

Gibberish check

The email address for random placement of characters indicates online fraud.

Domain check

The domain name is spelled correctly and the domain is valid and currently in use. Also checks whether the email is webmail (Google, Outlook, Yahoo) or a company domain email, indicating a private or a business email address.

Throwaway email check

The domain name belongs to an ESP (email service provider) for temporary email addresses.

Catch-all check

If a server has a catch-all policy enabled, it will receive all incoming emails. Including gibberish and mistyped emails but will result in a bounced message. Catch-all email addresses are set up to avoid unwarranted (mostly spam) emails.

MX record check

If there are MX records on the domain, the email address can receive emails. In other words checks if the email address is connected to a registered, hosted, and active domain, which is accessible online.

SMTP Authentication (Server ping)

Sending a ping to the email address to see if it can receive and respond to an email message. (One of the best and most reliable methods of email verification)

Why email verification is important

Still not quite sure why you should verify your emails?

Here are four reasons why you should always verify your emails before you start your outreach:

1. Keep your data up to date

Information as with everything else eventually become dated and obsolete. People change job positions, companies, domains get shut down and the data you had in your database, becomes effectively worthless. From a data platform perspective, that means bad data and dissatisfied clients.

That is why you need to keep your emails verified if you want to keep your CRM contact data up to date.

2. Email deliverability

With email verification, you can filter invalid emails and reach out only to message those emails that connect you to a potential client. Which also improves your open rate and keeps your bounce rate low.

3. Low bounce rate

Email bounce rate is important. If you are sending emails to an invalid address, that will cost you in the long run by damaging your conversion rate score. In will also result in penalties to your account and will damage your domain reputation.

4. Maintain domain reputation

Low domain reputation is indicative of spam and combined with a high bounce rate and low email deliverability will result in your domain rank/authority. However by using an email verifier to validate potential email addresses you can save from problems down the line. That is why it is best to think proactively, not retroactively.

How to choose an email verifier?

There are a lot of available email verification services on the market. Depending on your needs, whether you need a single or bulk email verification or a software or a cloud-based solution.

Software email verifiers are mostly enterprise solutions for a high volume of email addresses with dedicated personnel delegated to the task of managing the lead process.

Offering a one-time payment and a local database with an unlimited number of email verifications for bigger companies may sound tempting. However, the limited hardware access, software compatibility dependency, the need for an additional backup server, and the mandatory updates are surely a major drawback.

The saas (software as a service) market offerings as Sales.Rocks tackled these issues head. Offering unlimited access, competitive subscription pricing options for small, medium, and large companies, and streamlined ease of use process.
