Why is Email Validation a critical success factor in email marketing?

Email validation can raise or fall your email engagement and ROI.

Here are the standard parameters for email validation checks to increase email engagement.

Recipient Authenticity:

In email deliverability terms, low open rates are a clear signal to ISPs that your recipients don’t engage with you or your emails.

Low engagement can affect badly the delivery rate which can eventually block your email marketing campaign.

And it’s only the tip of the iceberg, having your emails blocked leads lower open rates, which tanks your engagements ever lower.

Invalid accounts can tear down even the most well-tailored marketing campaigns.

The last thing you want for your business is to be known as a spammer.

Email validation can help you avoid this and maintain a good sender reputation.

Email Service Provider (ESP), Internet Service Provider (ISP), and target audience are what you hang by a thread if you become a spammer.

It is what it is, marketing subscriptions is no fairytale, you can’t change your information whenever you feel like it and you certainly can’t do whatever you like.

Your target audience members won’t always remember you.

So if they see your email and they don’t like it, some will report you and you can kiss goodbye your sender reputation.

That’s why an email validation will spare you the unnecessary headaches of running your email marketing campaign.

Email validation is a great strategy to stay relevant and gather as many benefits as possible from an email marketing campaign.

Otherwise, your emails are like pouring water on sand.

High Deliverability:

Email deliverability determines if your marketing emails are delivered to the recipients on your email list.

The best-case scenario is your emails get delivered to your recipients’ inboxes.

If they don’t, you have to know what stops them from that.

There are different reasons behind your low email deliverability.  There are other reasons that could trigger the spam filter of your recipients. Here are a few examples:

-Your subject lines in ALL CAPS can send the emails to the spam folder of your recipients.

-If you don’t have the email permissions from your subscribers’ list can be a reason why your campaigns end in the spam folder.

-If your email campaigns keep getting spam marks, an email service provider like Gmail, Outlook, and Yahoo Mail will be aware of your placebo spam behavior which can affect your sender reputation.

Lower Bounce Rates:

Bouncing emails are like bouncing checks.

Bouncing emails are something no business wants to see.

One of the amazing things about email validation is how effective at removing email hard and soft bounces.

When using email validation, there is a chance to have a 10x reduction in bounce rate.

This 10x reduction in bounce rate can translate to a decrease in bounce rates by 90% after email verification in email marketing campaigns.

How to Choose an Email Validation Service?

Email validation services are the quick fix for email validation.

Online Presence:

Opt for the email validation SaaS (Software-as-a-service) services.

Reviews are also a great resource to discover the services’ other offers.


Email validation service providers should be able to integrate the process with other tools.

Other tools like email forwarding, email hosting, email archiving, and other tools.

Email volume:

Email validation service providers should be able to manage large amounts of email volume.

Most email lists can be validated instantly if the email validation service is scalable.

There is another point to email volume.

The mailbox providers and Internet Service Providers constantly check your sending patterns and frequency to determine if you are legitimate or spammy.

The number of emails sent, if it passes a certain volume per day, can inflict your sender reputation.
