Introduction
Email addresses are the foundation of every email address, so it stands to reason that validating them is a vital part of ensuring you’re sending messages to the right people. If your email address is invalid and your recipient puts up with it, there’s nothing more annoying than getting a message from someone that looks like this.
You’ve heard these warnings before but still, want to send an email? Here’s how to make sure the person on the other side has an actual human being’s name and phone number written down somewhere in order for their next birthday card message or bill reminder payment not be lost forever because their inbox got too full.
Why is email validation important?
Email validator is important because it ensures that your messages reach the right people. If an email address isn’t valid, you won’t be able to send a message.
If an email address is valid, your message will go through and be delivered as intended.
What are the rules for validating email addresses?
There are three rules that you should follow when validating an email address:
- The to-domain name (e.g., “foo@bar.com”) must be present in the address.
- The domain name (e.g., “foo@bar”) must be present in the address.
- You can’t have both a to-domain name and a domain name in your validation process!
How to validate an email address using a regular expression
To validate an email address using a regular expression, you’ll use the .*@[A-Z0-9._%+-]+@[A-Z0-9.-]+\.[A-Z]{2,4}$ pattern. This ensures that the entire address is valid and doesn’t contain any invalid characters or numbers. The pattern is also case sensitive so you need to make sure that when you’re using it in your script or programmatically, you’re matching each character exactly as they appear on your computer screen.
More sophisticated approaches
You can also use a service to validate email addresses, such as the one offered by MailChimp. You’ll need to provide their service with your contact information and they will send you a link in an email that allows you to confirm any or all emails as legitimate.
If someone sends an email from [your business name]@example.com, it’s likely not theirs and so it won’t be forwarded on by default (unless explicitly marked “do not forward”).
Using a service to validate email addresses
If you’re looking for a way to validate email addresses, there are two services that can help:
- MailTester is an open-source tool written in PHP and Linux shell syntax. It lets you test whether an email address is valid or not by sending it to a special mail server.
- Email on Acid (EoA) is the same thing as MailTester but for testing SMTP servers instead of regular emails. They both work using webhooks so that when someone clicks on a link in their email application such as Gmail, they receive information about what has happened without needing any extra software installed on their computer. This makes it easy for companies who want to add verification checks without having to develop anything themselves!
So, why is all this so important?
Email validation is important for a number of reasons. For one, it helps to ensure that your email address is only used by legitimate people and businesses. This can help you avoid spam or malware attacks from malicious actors who may be trying to sell you something over the internet (or worse).
It also helps security professionals make sure that emails are being sent from valid domains and not spoofed ones. Spoofing involves sending out certain types of messages under another domain name so as not to raise any red flags when someone receives them in their inboxes; this practice has been known since at least 2004!
Conclusion
There are many reasons why an email validator is important. It helps protect your brand from spam, viruses, and other malicious content. It also protects your users’ privacy by ensuring they have been authorized to receive messages from your organization.
