E-Mail Validator

Like most people, you probably have a love-hate relationship with e-mail. On the one hand, it's a great way to stay in touch with friends and family. On the other hand, it's a never-ending source of stress and anxiety.

But there's one thing that we can all agree on: e-mail is a necessary evil. And one of the most annoying things about e-mail is having to deal with invalid addresses.

That's where our E-Mail Validator comes in. You can verify that an e-mail address is valid and active with just a few clicks. No more bounced messages or wasted time!


An e-mail address is a string of a subset of ASCII characters separated into two parts by an @ symbol. The local part, the part before the @ sign, can include any of the ASCII characters! (U+0021) to + (U+002B), as well as the dot character. (U+002E). The domain part, the part after the @ sign, can include any ASCII character! (U+0021) to + (U+002B), as well as the dot character. (U+002E). The requirements for the domain part are more stringent than for the local region.

The following RFCs related to e-mail address format are currently in use:

- RFC 822: Specifies the format of internet text messages. This RFC was published in 1982 and specifies a mailing list syntax still in use today.
- RFC 1034: Specifies how domain names should be represented in internet protocols. This RFC was published in 1987 and updated in 1993.
- RFC 1035: Specifies how DNS records should be stored and retrieved. This RFC was published in 1987 and updated in 1993.
-RFC 2822: This RFC was published in 2001 and updated some of the details specified in RFC 822. It obsoletes RFC 822 but not RFC 1034 or 1035.
-RFC 3696:This is an informational RFC that was published in 2004 and guided internationalized e-mail addresses

What is an E-Mail Validator?

An e-mail validator is a software program that checks the validity of an e-mail address. It does this by verifying the syntax of the e-mail address and checking whether the address is formatted correctly and exists.

There are several reasons why you might want to use an e-mail validator. For example, suppose you are running a marketing campaign and gathering e-mail addresses from potential customers. In that case, you will want to ensure that all addresses are valid before sending your e-mail. This will ensure that your e-mails are not bouncing back and that your marketing campaign reaches as many people as possible.

E-mail validation is also essential for setting up a new e-mail account. By using an e-mail validator, you can be sure that the address you are using is not already taken and is appropriately formatted. This will save you time and frustration in the long run.

There are several different ways to validate an e-mail address. You can use a simple syntax checker to verify that the address is formatted correctly. This is usually sufficient for most purposes. However, if you want to ensure an address is valid, you can use a more sophisticated method known as MX Record checking.

MX Record checking involves checking the DNS records for the domain name associated with the e-mail address. This method is more time-consuming but provides a higher accuracy level. Regardless of your chosen method, an e-mail validator can save you time and hassle in the long run.

How does an E-Mail Validator work?

An e-mail validator works by checking the syntax of an e-mail address to see if it is in a valid format and by checking with the domain's mail exchanger to see if the mailbox exists.

The first step is to check the e-mail's syntax. This involves ensuring that there is one "@" symbol and no illegal characters in the e-mail address.

The second step is to check with the domain's mail exchanger to see if the mailbox exists. This is done by sending a "mailbox inquiry" to the server. If the mailbox exists, the server will return a positive response. The server will return a negative response if the mailbox does not exist.

What are the benefits of using an E-Mail Validator?

An E-Mail Validator can benefit you in several ways:

1. Reducing undeliverable e-mail - An invalid e-mail address can cost you time and money sending e-mails that will never be delivered. Using an E-Mail Validator, you can ensure that your e-mail list is clean and that your messages reach their intended recipients.

2. Improving deliverability rates - In addition to reducing undeliverable e-mail, an E-Mail Validator can also help improve your overall deliverability rates. This is because many ISPs use e-mail validation as a part of their filtering process, so having a valid e-mail address makes you more likely to have your messages delivered to the inbox.

3. Saving time and money - By using an E-Mail Validator, you can save both time and money by not wasting time sending messages to invalid addresses or spending money on postage for physical mailings that will never reach their destination.

How to use an E-Mail Validator?

An e-mail validator is a tool that can be used to check whether an e-mail address is valid or not. Many different types of e-mail validators are available, but they all work in the same way.

To use an e-mail validator, enter the e-mail address you want to check into the appropriate field on the validator's website. Once you hit the "validate" button, the validator will contain the address against a database of known e-mail addresses. If the address is found in the database, it is considered a valid e-mail address.

It should be noted that just because an e-mail address is considered valid does not necessarily mean it belongs to a natural person. Someone can create a fake e-mail address and use it for nefarious purposes. Therefore, it is always wise to use caution when using any online tool, including an e-mail validator.

Tips for using an E-Mail Validator

E-mail validators are software programs that check whether an e-mail address is valid. This is done by checking the syntax of the e-mail address and whether the e-mail address's domain name can be resolved.

E-mail validators often prevent incorrect or invalid e-mail addresses from being entered into a database. They can also be used to check whether an e-mail address exists to avoid typos or mistyped addresses.

When using an e-mail validator, there are a few things to keep in mind:

1. Make sure the program you're using is updated. New domains are constantly created, and an outdated program may not recognize them.
2. If you're using a validation program on a website, make sure it's fast. Users won't want to wait around for it to check their address.
3. Make sure the program you use can handle simple and complex e-mail addresses. The latter may include unusual characters or be very long.
4. Some validation programs will give you a list of suggested corrections for an invalid e-mail address. If this is the case, ensure you understand how the suggestions are generated before implementing them.
