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.
Why do we say ‘Valid’🤔?
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 effort and expense.

So let’s dig into what makes a valid email address format and how Clearout can help you validate email address formats.
What is a valid email address format?
First of all, let’s understand what a valid email address contains:
1. The local part or username – Indicates a unique mailbox name, which can consist of any combination of letters, numbers, and 7bit ASCII special characters (more on those later).
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 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.

Why Do You Need To Validate Email Addresses?
Such invalid emails entering your system should not be taken lightly as there can be serious consequences of sending out email campaigns to these emails. Wasted resources, high bounce rate, 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, if you don’t want to land in a lot of hot water by sending out emails to invalid email addresses, you need to set up a system to identify, validate, and stop such emails from degrading your database.
