The verification or validation of email addresses is a fundamental need in many applications, ranging from protection against phishing and various other email-based threats through the validation of data filled in into an online form to the purification of marketing or other email lists from invalid addresses to maintain sender reputation and avoid bouncing or other unnecessary email traffic.

Strengthening Email Security Solutions & Validation Programs with a Disposable Emails Database

Email validation has become a necessity for organizations that aim to protect themselves against cybersecurity threats. The process becomes all the more relevant as 65% of attackers use phishing as a primary infection vector. That’s not a surprise, since attackers have long been weaponizing emails to serve as entry points for cyberattacks.

The ease with which threat actors can create disposable email addresses also contributes to the threat. In less than a minute, they can create a temporary email address with tons of providers, which they then use to send malware-laden and phishing messages to target victims. For this reason, a disposable email domain database can make email security vendors and email validation programs in general more robust and comprehensive. Let us elaborate on that.

Bulk Email Verification and Validation for 3 Cyber Threat Protection Use Cases

Email validation is one of the most potent measures to ensure that digital marketers’ messages get through to their intended recipients. But amid the rise in cybercrime and fraud, the practice has become more than that.

Email validation has also turned into a viable option for streaming service providers to prevent fake or fraudulent subscribers from gaining access to the content they’re unauthorized to view. Amid this backdrop, organizations would do well to add bulk email verification to their standard business protocols. Here is why.

Is This Email Address Valid? Here Are 5 Ways to Check and Why It Matters

Based on research data, the global email user base will be increasing by 2-3% every year until it reaches 4.4 billion users in 2023. So, more than ever, email marketers need to be able to answer the following questions: Are all the email addresses in my recipient lists valid? Will my messages be able to reach intended recipients or not? Also, do any of my collected addresses have ties to malicious activity?

Each day, users send an average of 54 billion legitimate emails across the globe. Interestingly, a whole lot more malicious spam messages get sent, averaging 302.99 billion a day. When threats are everywhere, the mere act of opening spam could lead to becoming the next victim of phishing or an even more sinister attack.

On the other side of the fence, meanwhile, marketers are worried that their messages may not reach the right people. A lot of organizations suffer from high bounce and low open rates, with adverse effects on their marketing efforts. Sadly, no matter how great your campaigns are, if your emails do not reach loyal customers or leads of interest, your efforts are bound to go down the drain.

To alleviate these and other issues, organizations need a means to be able to check the validity of email addresses they come in contact with. So, email verification with products such as Email Verification Lookup or its counterparts Email Verification API or Email Verification Bulk API can be integral to any company’s successful and efficient operations. To illustrate how these tools work exactly, we listed down five supported email checks in this post.

Key Features Your Email Validator or Verifier API Should Have

Email remains the most preferred platform for business communication. In marketing, the most efficient way to reach a company’s target audience regardless of their age is through email. The current email open rate stands at 22.86% compared to social media’s engagement reach of 3.71% only.

Therefore, it is not surprising that a lot of today’s cybersecurity threats still arrive on networks via emails. In fact, 90% of threats use email as an attack vector. Malware-carrying messages that use effective social engineering ploys still manage to trick unsuspecting users into downloading malicious attachments or clicking embedded harmful links.

And while advanced security solutions protect networks against these dangers, not all companies can afford to buy expensive offerings to defend their assets. But those that want to take steps to stay safe from email-based threats can rely on a product such as Email Verification API. Of course, other security solutions that can detect and block spam are also critical in defending your network. However, you can also integrate a multifunctional and reliable email validator API into these as an additional layer of security.

You may be wondering how an email verifier API, which marketers typically use, helps with cybersecurity. This post will tell you all about it.

6 Compelling Reasons Why You Should Check Email Address Owners and Other Email Security Tips

An email address is, perhaps, one of the most overlooked network-accessible resources. Many highly publicized attacks are attributed to a phishing email link that an unsuspecting employee regrettably clicked on. Also, business email compromise (BEC) accounted for 50% of total losses among organizations or $1.2 billion in 2018. Yet despite all the constant warnings and devastating examples, these attacks keep on happening. Why is this so?

The occurrence could be bewildering indeed for cybersecurity professionals who deploy the most advanced endpoint protection and intrusion detection systems (IDSs) there is. Unfortunately, all efforts to ward off attackers can prove irrelevant unless you educate employees on good email hygiene or implement the right email security policies.

This post aims to do precisely the following: provide employees with some guidelines on how to recognize potentially dangerous email addresses. It also illustrates the many ways in which an email verification API can mitigate the problem.

Email marketing remains one of the most effective marketing channels, with an average return of investment (ROI) of between 38:1 to 44:1. It has been helping organizations improve their customer acquisition and retention.

Several surveys show that emails drive purchases, and that around 17.75% of email clickthroughs convert to sales, a figure that has been gradually increasing over the years. However, email marketing comes with limitations and pitfalls, too.

Email marketers must thus understand that, to succeed, campaigns need to reach their intended targets, which is made possible by maintaining a clean email list.

How to Check If an Email Address Exists Using DNS MX Records, SMTP Connections, and Email-Sending Emulation

Nonexistent email addresses, which aren’t connected to any existing branded domain name, can spell trouble for organizations when used as part of a site’s registration process or in an online contact form.

Such addresses can be the product of human error. For example, a user may inadvertently mistype his or her email by omitting, adding, or switching one or more characters or words in it. However, using nonexistent email addresses can also be deliberate for different reasons...

Why You Should Add Email Address Validation to Your Email Security Best Practices

Despite the emergence of instant messaging platforms, email is still the king of digital communication, particularly in the professional and business world. The number of email users globally is expected to reach 4.3 billion by the end of 2023, which accounts for more than half of the world’s population. Also, the total number of emails sent and received every day is forecasted to rise to 347.3 billion by 2023.

Probably because of its vast userbase, email is also a common cyberattack vector. For instance, some 65% of cybercriminal groups use phishing as their primary infection vector, and almost 60% of IT professionals view phishing as a top security threat.

Spamming is another way by which threat actors enter an organization’s IT network. Spam emails are not only annoying, but they can also be dangerous as they may carry ransomware and other malware.

With that in mind, email security has become a top priority for organizations. And among the email security best practices is email address validation.

How to Validate an Email Address for Typos, Syntax, Curse Words, and Other Rules

Email marketing is without a doubt sound investment for companies. For every $1 spent on email marketing, the return on investment (ROI) can be as high as $32.28, according to DMA’s Marketer Email Tracker report.

The same study examined the respondents’ mailable list size, return rates, and delivery rates, and the findings are quite surprising. Some 55% of the respondents said there was a significant rise in their organization’s mailable list size, yet only 36% reported increased delivery rates. Also, 36% of the respondents said they encountered an increase in the number of returned emails.

While on average about half of the respondents increased their open, click-through, and conversion rates, we can’t help but speculate whether these numbers can still be improved if email marketers were to find a way to decrease return rates while increasing delivery rates.

One method that can help organizations achieve these goals is by making sure that the email addresses in their databases are valid. Valid email addresses can dictate the success or failure of any email marketing campaign.

Email validation with the use of tools such as Email Verification API should, therefore, be a necessary process when launching a campaign.

Email Verification Reduces Phishing

In the mid-90’s, when Tim Berners-Lee created the foundational elements of what would later become the World Wide Web, business and society entered the digital age. One of the many innovations that accompanied this technological transformation was email, which rapidly grew into the primary business communication medium.

Since then, the infiltration of social media and instant messaging apps have been chipping away at the dominance of email, but it still remains a critical component of modern IT architectures. However, due to its ubiquity, email is a common threat vector utilized by cybercriminals for nefarious purposes.

Why You Need to Validate Your Mailing List

Utilizing an email list can be a powerful marketing strategy for nearly any business. However, it’s not uncommon to build up a list of unresponsive email addresses. When you send emails to these addresses, they can bounce or simply sit in the recipient’s inbox, unopened. It may not seem like a big deal, but internet service providers can see this data and use it to determine the validity of your emails. If the provider sees emails from you bounce too many times, they may decide to classify your emails as spam, or even block them altogether. This is where email address validation comes in. There are ways to ensure you’re only sending to customers who really want your emails and will open them. But first, you should understand some basics.

Why Use E-mail Verification?

The history of e-mail dates back to the very early days of the Internet. The basics of the protocol were laid down as early as 1982, in RFC822. And even though this very early specification had been updated by RFC 2822 in 2008, and several updates have appeared since (e.g. 6854 in 2013), the basics of the protocol have not changed much. This is, on one hand, a considerable success of the protocol. It provides a solution to a very natural need of the users of the network: to use the Internet for sending messages like conventional mail. And this good old protocol still meets many of the requirements. In spite of the enormous amount of alternative means of online communication, e-mail has managed to maintain its popularity even today. The reasons for this include the simplicity of the protocol, the fact that it is indeed a standard. It is decentralized in the sense that there is no distinguished provider for which one has to necessarily subscribe to be able to use e-mail. This can indeed be an advantage when compared to e.g. social networks whose providers get hold of our private data when we use them.
