An email validator is a service that will check emails to ensure they are deliverable. Email validation services automate this process and can increase the performance of marketing campaigns. Essentially, they check that the mailbox address is actually valid and can receive messages. The process is similar to step one, except that the validation service will focus on the part of the address before the “@” symbol.
Verifying if an email address is deliverable
Before you send an email, it is important to verify that the email address is deliverable. This helps you prevent hard or soft bounces. Each email account has a sender reputation score, and the higher the score, the more likely the email will be delivered. This is based on a number of factors, including bounce rate. Sending an email to an address that has not been verified will almost certainly result in a bounce.
It is possible to find the email address of a recipient by performing a quick Google search. Most major search engines index everything on the internet, and a simple search can usually uncover valid emails. However, if the address is fake, your results will be much less accurate. Fake email messages are a major problem for marketers. To solve this problem, there are various email verification tools available on the market.
Checking for typos
If you have an email list, checking for typos can help you make sure your subscribers are legitimate. Invalid email addresses can affect your conversion rate, cause delays in invoice payments, or simply frustrate your subscribers. Luckily, there are email validators out there that can help you detect these mistakes. In addition to checking for typos, these tools can also detect other issues such as abusive words in the email’s body.
Email validators utilize AI and multi-layer testing techniques to identify potential problems. These sophisticated algorithms can determine if your email is prone to hard bounces or soft bounces, catch typos, and identify the incorrect email format. Some email validators even have the ability to determine when an email was last opened. This makes them a must-have tool for any modern marketing campaign.
Checking for internationalization
Internationalization of an email address can be a challenge. Non-internationalized email addresses only allow English letters and numbers, along with some punctuation. Internationalized email addresses allow a wider range of Unicode characters. In both cases, the character check is performed after Unicode normalization. However, it’s important to note that email validator even an internationalized email address isn’t completely protected, as there are many different Unicode characters that look the same. This can cause confusion and deception among human readers.
An email validator must be able to handle Unicode character sets. IETF has produced multiple RFCs that pass Unicode characters as valid email addresses. For example, it must be possible to have a period in the local part of an email address, as long as it does not lead or trail.
