Hence, you are left with the “cleaned” list of deliverable contacts. Now, your final list is filtered from any invalid ids. As a result, the efficiency and performance of your marketing campaigns significantly improve.

Email Validators are mainly responsible for:

  • Eliminating any duplicate emails.
  • Removing invalid domains by verifying DNS records.
  • Removing any address in an improper format, also known as Email id syntax.
  • Identifying disposable email addresses.
  • Identifying addresses in the format such as [email protected].
  • Detecting Spam addresses( Bots/ inappropriate emails)
  • SMTP Authentication.

Importance Of Email Verification Tools

To summarize, email verification services provide:

1. Better Deliveribality and Conversion Rates

The number of messages that are actually delivered to your prospect’s inbox rather than waiting in the spam box. This is what we mean by better deliverability rates. The more the rate of emails actually reaching your potential clients, the stronger your campaign is.

As more and more active emails are in progress, the possibility of conversion of a prospect to a client increases. Your campaign will be more measurable in terms of marketing metrics. Thus you can continue to restrategize and focus on the content, the value you want to deliver. Hence, your conversion rates are more optimized and streamlined.

2. Greater ROI

With the fake accounts being removed, your investment commits a stronger return. The organized list not only centres your marketing efforts but appeals to the targetted, warmed-up leads. They are invaluable assets for your business and hence, your returns are way more sustainable and better.

3. Stronger Sender’s Reputation

As mentioned earlier, your sender's reputation cannot afford cracks. Falling prey to spam traps and hitting the wrong address, harm your ranking. Before you know, they have unsubscribed from your emails. Thus, if you still have not found the right call to your verification needs, understand the impact.

Outbound marketing strategies require great finesse. Indeed, it is safe to say, with the right email checker, B2B marketers can become immensely successful.
