• HOW DOES CHECKER WORK

purechecker.com

How does email verification check if an email is invalid without sending an email, right? This can be very complicated, but with software emails is one of the easy parts. Here is how an email verification process works.

1. SYNTAX VALIDATION

This is the most basic part of email verification. This is the part where systems check if an email is in the correct format. The system checks if the email has invalid parts if is missing.

EXAMPLE: If an email is john.doe@gmailcom, the system can see that the email does not have the part of the email with the dot before "com".

2. DOMAIN AND DNS CHECK

With the email in a correct format, the checker should be able to check any info in the ddomain. It can be able to check the domain substring and if the DNS can be used and to system can get other info.

• MX Record Validation

A domain can exist, but can it receive emails? The tool searches for MX records, which tell the internet which server handles emails for a particular domain. If a domain does not have MX records, emails directed to that domain will bounce back.

• Email Validation via Handshake

The Email Validator tool connects to the recipient mail server (SMTP) to initiate a handshake process. Think of it as the tool is saying, "Hi, does this user exist?" The server will respond with a code that either confirms or denies existence of the user, only to later hang up that call before an actual email is sent. This allows the tool to verify existence without spamming the recipient.

• Spam Trap Detection

Spam traps are email addresses created by internet service providers (ISPs) and anti-spamming organizations. These email addresses are designed to catch spammers and are often flagged as spammers. Good email validation options have databases that include these so-called spam traps to ensure they are not included on email sending lists.

• Detection of Disposable Emails

A common tactic is for users to sign up for freebies using temporary email addresses, like a 10 Minute Mail email, so they can bypass normal engagement. These temporary addresses often lead to a hard bounce later on due to self-destructing features. Quality validation algorithms are designed to detect and flag these domains.

7. Catch-All Verification

A few domains are set up to accept all emails sent to them, no matter the username. Although emails sent to these addresses won’t bounce right away, these addresses are dangerous because they are often ignored or used as spam traps. An advanced checker can spot "accept all" servers so that you can make an informed decision about the risk.

Why You Need a Bulk Email Checker for List Hygiene

Checking emails one by one is an option if you have ten contacts. But if you have thousands in some sort of a database, manual checking is out of the question. A bulk email checker is essential in that case.

Protecting Your Sender Reputation

As for sender reputation, it is a score given by ISPs to your IP and domain, and it works similarly to a credit score.

High Score: Your emails land in the Inbox.

Low Score: Your emails land in the Spam folder or get blocked altogether.

A bulk email checker will clean your entire email list all at once and in turn, allows you to keep a low bounce rate (ideally below 2%).

• Financial Benefits

Email service providers such as Mailchimp or HubSpot charge based on the number of subscribers on their email lists. When a fifth of your subscribers are invalid, you are overpaying to keep information that gives you a negative value, or no return on investment. Cleaning your email subscribers can drop the monthly costs of your service provider.

• Metrics Improvement

Engagement metrics such as open rate and click through rate determine your net email engagement. This number is calculated based on emails delivered. When you clean your list of dead weight, your engagement metrics as a whole increase. This is valuable to ISPs as it indicates your content is engaging and worthy of being received and opened.

• Best Practices for a Healthy Email List

These habits will build even more value on top of the existing value generated by your email list cleaning tool.

• Use A Double Opt-In\*\*: This is a way of verifying that email subscribers are legit. A system that requires email subscribers to confirm their address is a solid way to prevent email typos and invalid emails that clutter and slow down your database.
• Clean Regularly\*\*: Email lists aren’t static as subscribers change jobs, abandon accounts, and let email service providers collect dust. Lists of siloed emails depreciate by 22% every year. At a minimum, email lists should be run through a bulk email verifier once every 3 months.
• Segment List By Engagement\*\*: If someone hasn’t opened an email in the last six months, it is appropriate to pull that email address for an additional verification step, or remove it altogether.

Spam traps and fraudulent information fill purchased lists. It's better to build your own list naturally.

• Common Inquiries Regarding Email Verification**
• Q1: Is utilizing email verifiers legal?**
• A1:** Certainly. In fact, it is the legal right of anyone to use email verifiers. Accuracy of email is vital to compliance when it comes to regulations like the GDPR (General Data Protection Regulation). Cleaning your email lists for verification means you're not holding onto irrelevant or outdated email addresses, which is a violation of GDPR.
• Q2: How frequently should one use bulk email verifiers?**
• A2:** This is largely dependent on the growth rate of your email list. An ideal rule is to perform verification of your email list every 3 to 6 months. But if you are utilizing a questionable practice of acquiring leads (which we highly advise against) or data scraping, it is important to verify your email lists as bulk email verification is a legal requirement before sending any email.
• Q3: Will the owner whose email I verify know?**
• A3:** No. No one will know because the verification process is silent. Verification tools will ping the email server, however, they do not send an email to the person's inbox so they will not receive a notification.
• Q4: What is the difference a soft bounce vs a hard bounce?**
• A4:** Hard bounces are permanent and mean that the email does not exist, and an email checker will identify these. A soft bounce means it is temporary, for instance the person's inbox is full or the email server is down. Checkers are not always able to predict a soft bounce as these scenarios are temporary.

Q: Are Gmail and Yahoo addresses verified?

A: Yes. Modern checkers can verify Gmail, Yahoo, and Outlook, as well as custom business domains. However, some free providers have highly restricted firewalls which require more sophisticated checkers to bypass.

Is it worth it?
