What is a Valid Email Address Format?

Email marketing is one of the strongest ways to connect with your target audience and convert them. But to run email marketing campaigns, you need ‘valid’ ✅email addresses.

Firstly, it is important to ensure that the email address is correct and actually exists so that you know you are reaching out to a real person.

Secondly, invalid email addresses can ruin your database, resulting in hours of wasted efforts and expense.

So let’s dig into what makes a valid email address format and how Clearout can help you validate email address formats.

First of all, let’s understand what a valid email address contains:

1. The local part or username – Indicates a unique mailbox name consisting of any combination of letters, numbers, and 7-bit ASCII special characters. In the local part, periods are also acceptable, provided they aren't the first or last character.

2. The symbol – You cannot have an email address without the symbol. It is the connector between the person who owns the email address and the domain.

Including the @ symbol, it allows your email program to recognize the first half of your address as the username and the second half as the domain name.

3. The domain – Each domain occupies a unique place on the web and is controlled by a particular mailbox provider or association.

It consists of one or more parts separated by a dot. Each part must be no longer than 63 characters and can contain any combination of letters and numbers without having a hyphen as the first or last character.

Hence, an email with all of these elements per the guidelines is a valid email address format.

Now, let’s have a quick look at what invalid email addresses are and their cause.

An invalid email address refers to an email address that doesn't meet the necessary criteria for proper formatting or functionality and cannot receive emails. They are like zombies: dead but able to eat away your email campaign's life actively.

1. Human error– Typos can happen at the point of access by either the person trying to signup or by a company representative when getting the information. Sometimes users intentionally provide incorrect information for exploiting the system for free with multiple signups.

2. Formatting– Email addresses must consist of 4 components: the regional address, @, the domain name, and the domain name identifier. If an email address is missing any of these components, it will be invalid, and there will be no inbox for messages.

3. Domain– There are circumstances when an email address fulfills the format criteria. However, it can still be void if the domain no longer exists. This may happen if a business goes out of business or changes names.

4. Missing mailbox– An email address also becomes invalid when no mailbox is attached to it. This happens when the mailbox is deleted/deactivated by your ESP or if the server is not reachable.

5. Abandonment– When a person switches to a new account with the same or a different email supplier, the original email address commonly gets deserted and becomes invalid due to no engagement.

Knowing what is a bad email address or what makes an email addresses invalid and how they get into your system can help you stop them immediately from hindering your email campaign's performance. This is why validating all email addresses entering your database is essential.

Invalid email addresses entering your system should not be taken lightly, as there can be severe consequences for sending out email campaigns to invalid emails. Wasted resources, a high bounce rate, a poor ISP rating, and more—you will end up tarnishing your reputation and your brand.

For example, a 10% hard bounce rate in an email marketing campaign causes email provider blockades, resulting in only 44% of emails reaching inboxes. Moreover, fewer emails in the recipient's inbox already affect your results, exacerbated by email provider blockings such as soft and hard bounces.

Therefore, to avoid landing in a lot of hot water by sending emails to invalid email addresses, you need to set up a system to identify, validate, and stop such emails from degrading your database.

As mentioned, an invalid email address can cause a host of troubles for your organization. So how do you ensure you avoid falling prey to these scenarios and only collect emails that both exist and benefit your company?
