Preparing for the End of Third-Party Cookies

It’s almost the end of an era in advertising. Google has started phasing out third-party cookies, beginning with 1% of Chrome users in January 2024. It plans to do the same for all users by the second half of the year through the Privacy Sandbox initiative.

To recall, Google’s Privacy Sandbox is a set of proposals for creating new standards for online privacy. The core idea is to develop methods for websites and advertisers to access user information for things like advertising and content recommendations without compromising user privacy. Among its key goals? Phasing out third-party cookies.

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

Validating email addresses upon user signup is an important process that can help improve the quality of your email list and reduce the number of bounced emails.

Nonexistent, invalid, or fake email addresses, which aren’t connected to existing business domain names, 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, users may inadvertently mistype their email addresses by omitting, adding, or switching one or more characters or words. However, using nonexistent email addresses can also be deliberate for different reasons that include:

How to Improve Email Deliverability: 5 Best Practices

Did you know that for every dollar you spend on email marketing, you can get as much as a US$42 return on investment (RoI)?

But what is the definition of email deliverability, exactly?

How to Create an Email List for Effective Marketing Campaigns

How to Create an Email List for Effective Marketing Campaigns

More often than not, the success of any marketing campaign depends on how well a company creates an email list and maintains it. If your distribution list is chock full of invalid and unreachable email addresses, for example, chances are your marketing campaign won’t succeed.

Organizations that rely on email marketing for their revenue need to create clean email marketing lists if they want their campaign messages to reach intended recipients. But how can they do that? And what exactly is an email marketing list?

Email Address Format and Syntax Explained

Email Address Format and Syntax Explained

Have you ever wondered what it means when people say that email addresses should follow the standard set by the Internet Engineering Task Force (IETF), the organization tasked to set up standards for Internet usage? Simply put, it has to do with email syntax. In this post, we’ll tackle what the right email syntax or format is, what email syntax errors are, and how email syntax validation can help reduce issues.

What Is a Catch-All Email Address? How Do You Verify It?

What Is a Catch-All Email Address? How Do You Verify It?

There are at least two opposing views on using catch-all email accounts. One is that employing such an account allows users to get all messages sent to their email domains. Another is that users are likely to receive more spam since a catch-all email address accepts all incoming messages. For digital marketers, the question then is: Is sending messages to a catch-all email account a boon or a bane? And we can answer that by going through the basics first and then drilling down into a way to detect and verify catch-all emails.

Email Terminology: 20+ Terms for Marketing and Email Verification

Email as a technology may be old and gray by now, but it hasn’t lost its sheen, as it remains a (if not “the”) primary business communication medium. Like any Internet-based tech, however, not everyone who uses it knows everything there is to know about it.

They may not know, for instance, how email marketing can help companies thrive exactly or why email verification is important. This glossary aims to shed some light on these topics by diving into essential email marketing and email validation terms and concepts.

GDPR and Email Marketing: Everything You Need to Know

In the modern marketplace, business leaders must work hard to reach new customers and stay in touch with existing ones at all times. Creating email lists and verifying them is often a cost-effective and reliable way to boost marketing efforts. But of course, when executing a marketing campaign, no business owner wants to run afoul of the law. The General Data Protection Regulation (GDPR) is critical to consider. But with all the noise surrounding business, marketing, and law, one may wonder how the GDPR affects email marketing and email lists.

Before we can answer that question, we first need to learn more about the GDPR.

How to Reduce Your Email Bounce Rate with Email Verification

How to Reduce Your Email Bounce Rate with Email Verification

Most online marketers have to contend with bounced email notifications from time to time. And bounced messages are marked “undeliverable” for a variety of reasons. Bounce rates vary and generally range from less than 0.4% (great) to 1.5% or more (critical), according to Klaviyo. However, specific lists may have even higher rates. Frequent email bounces don’t only reduce the effectiveness of marketing campaigns, they may eventually prevent messages from reaching their intended recipients.

How to Clean Your Email List with Email Verification Software

How to Clean Your Email List with Email Verification Software

Email marketing remains one of the most effective online marketing strategies today. And these statistics prove that:

  • Around 4 billion users send and receive emails daily.
  • Email marketers who employ segmented campaigns have noted as much as a 760% increase in revenue due to the strategy.
  • Four out of five digital marketers would rather give up social media than email marketing.

As shown, despite the ever-growing popularity of social media marketing, many companies still rely more on email. And the reason could be that they believe it’s less intrusive. That is especially true when it comes to receiving messages from people the recipients do not personally know.

Verify the Abuse Email Address of a Domain in Python

This post teaches users to develop a Python program based on WhoisXML API’s email verification package, python-email-verifier that returns the valid and working abuse email address of a domain if it exists. But let’s start with the basics. What is an abuse email address, exactly? 

What Is Email Verification or Validation and How Does It Work?

Email address verification or validation is fundamental to many business processes, especially marketing. Validation begins when users fill in online forms and continues on until filtering invalid email addresses out of marketing or other lists to maintain one’s good sender reputation, avoid bounces, and block malicious messages, as illustrated in greater detail in several other posts

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

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.

That makes answering email marketing questions more crucial than ever. Is this email valid? Are all the email addresses in my recipient lists valid? Will my messages reach their intended recipients?

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.

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.

Whois XML API provides infosec professionals with tools to reduce the risk of hackers using email to infect devices and steal user credentials.

Top 3 Ways to Bring in More Sales By Using Email Validation

There's a fine line between consumer data accuracy and easy user experience (UX). For marketing purposes, you want to harvest accurate consumer data and, luckily, there are many web applications available to help you do just that. However, some of them are obtrusive, stopping the customer in their tracks and frustrating them in their quest to validate information. There are also others that send confirmation messages in an effort to increase data accuracy without interference but often with poor results. That leaves many businesses with outdated sign-up forms to reach out to consumers, which is a shame because they could be doing much better.

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.
