As of 22 September, Internet Live Stats tallied more than 70.4 trillion emails sent in 2020. And with around 4.57 billion Internet users worldwide, that translates to an average of 57.9 emails per person a day. 

These numbers are a lot to take in. For organizations, they mean two things-too much competition fighting for people's attention and too many cyber threats coming in via email. An email verifier API can, however, help them cut through the noise. In a nutshell, the tool checks the validity and existence of an email address.

How an Email Verifier API Can Help Organizations

An email validator API can help address some marketing and cybersecurity issues that an avalanche of emails bring. It can help marketing teams avoid spam traps, reduce bounce rates, and improve their overall email deliverability. In terms of cybersecurity, an email verifier API can augment email filtering systems. For more information, visit

Avoid Being Tagged as a Spammer

Around half of all emails sent are believed to be spam, and most are marketing emails. That is quite disheartening, as it means that your marketing emails could, unfortunately, be treated as spam. And so, marketers should avoid being tagged as spammers, and one way to do that is by evading spam traps using an email validator API.An email verifier API uses email-sending emulation techniques to check for Simple Mail Transfer Protocol (SMTP) connections. An email address without an SMTP connection is not meant to send emails and is essentially a spam trap. Such email addresses were created for the sole purpose of catching spammers, particularly advertisers who didn't ask the recipients to opt in to their marketing emails first.

When you send even a single email to a spam trap, you run the risk of already being tagged as a spammer by Internet service providers (ISPs) and email service providers. As such, ridding your distribution list of spam traps using an email verifier API can help your emails reach recipients' inboxes and not their spam folders.

Reduce Bounce Rate and Improve Email Deliverability

Aside from detecting spam traps, an email verifier API's email-sending emulation techniques confirm the validity of email addresses on your mailing list. This process ensures that your marketing and advertising emails are sent only to valid and existing email addresses, thereby reducing bounce rates. Over time, your email deliverability rate will also improve.

Included in the 70+ trillion emails sent could be those that bounced back, so it's essential to keep your bounce rate as low as possible to compete with all other marketing emails. Ideally, you can integrate an email validator API into your signup page to keep invalid email addresses and free-trial abusers away.

Keep Spam and Phishing Emails Out of Your Network

An email validator API can detect disposable email addresses. These are email addresses from temporary email service providers such as 10MinuteMail, TempMail, and GuerillaMail. Disposable email addresses are mostly used by spammers, phishers, freemium abusers, and other malicious actors. They are easy to obtain and can be dropped and replaced instantaneously in case they are blocked.

Keeping disposable email addresses from entering your network is a massive step toward protecting staff, clients, and end-users from phishing and other cyber attacks. Remember that a good portion of emails sent every day comprises phishing emails. As such, integrating an email verifier API into email security systems can help boost cybersecurity.

Email is still one of the most preferred communication platforms worldwide. And the fact that trillions of emails are sent as of the third quarter alone can attest to that. This volume of emails, however, highlights the importance of email verification. It is a crucial process not only in marketing but also in cybersecurity.
