Email Marketing is very important to grow your online business. A marketer who does marketing online is already aware of Email Marketing. Online Marketers send the bulk of emails to promote their products and services. Also, email marketing is an essential tool for affiliate marketers.

Marketers do email marketing campaigns and after successful completion of the campaign, they get a list of email addresses. How will they ensure the quality of the email addresses?

Email Verification is the process by which marketers can ensure the quality of the email addresses. Many times visitors provide an invalid or incorrect email address. Sending emails to those wrong email address leads to bounce email and may lead to account suspension. Your business cost may get higher due to this and your productivity will decrease.

So to avoid this type of situation, every marketer should carry out the process of email verification.

What Is Email Verification?

Email Verification is the process by which we determine whether or not a list of email addresses is fully valid, accurate and deliverable. A high-delivery rate is essential to get on improving the sales. In fact, we can say that it is the process of cleaning the email list.

Before sending the bulk of emails, you should verify those email addresses to ensure high-deliverability rate. For example; you have an email address list for email marketing purpose. Many of the email addresses in that list are invalid or wrong. Sending emails to invalid email addresses leads to high email bounce rate and ISPs will start treating you as a spammer.

After that, the emails you send will go to the Spam folder and nobody will read it.

That’s why email verification is a vital process for every marketer who does email marketing. This process should be done on a regular basis. Your bounce rate may get an increase if you a marketer do not verify email list regularly.

Although there are several email verification services available. Choosing the right one is a complex and time-consuming process.

Below is the list of best email verification services that do perfect email validation and verification work.
