How to Create a Valid Email Address List
Email marketing is one of the most profitable digital marketing channels out there, but only if you do everything right and by the book. There are plenty of conditions to meet, and one of them is having a pristine clean email list.
Today, we have the key to cleaning up any email list and powering up your next email marketing campaign.
What is a valid email address list?
Valid email address lists are collections of email addresses that conform to standard formats and meet specific criteria.
These are email addresses that are:
- correctly structured
- active (the address is still in use)
- obtained legally and ethically, with the recipients’ permission
Only with a valid email list can you expect high open- and click-through rates and conversions from your emails.
What does a list with valid email addresses look like?
Here are some ways to know that you have a list with fully valid email addresses.
-
Follow the correct format
Each email address should conform to the standard format of “[email protected],” where the username consists of alphanumeric characters, periods, underscores, and hyphens.
Also, the domain should be a valid domain name with a proper top-level domain (the bit at the very end, such as .com).
✅ Good example: [email protected] ❌ Bad example: “johndoe”@exmple.com (contains an invalid character “) |
-
Have active and deliverable status
The email addresses should be actively used by their owners, allowing them to receive emails in the mail server. Sometimes, people leave companies or change email addresses and an address you had before is no longer usable.
A valid email address list excludes addresses that are abandoned, inactive, or non-functioning.
✅ Good example: ja[email protected] (regularly receives and responds to emails) ❌ Bad example: [email protected] (created for testing purposes and probably deleted since its creation) |
-
Originate from opt-in or permission-based sources
Moving forward, the addresses in the list must be acquired legitimately and with the explicit permission of the recipients.
This means they have willingly subscribed, opted in, or given consent to receive emails from the sender.
Purchased or scraped email lists, which often contain addresses without consent, are not considered valid. Some emails you send to those list could get delivered but there is a good chance that many addresses are fake or inactive.
✅ Good example: newsletter_sub[email protected] (explicitly opted in through a sign-up form) ❌ Bad example: [email protected] (obtained from a third-party vendor without explicit consent, emails end up in the spam folder) |
-
Undergo regular cleaning and validation
Your valid email list should undergo routine maintenance to eliminate invalid or non-functional email addresses.
This involves a few actions. For example, you might verify the syntax of each address or check the existence and accessibility of the associated domain using an accessibility checker.
Another possible procedure is removing addresses that have resulted in delivery failures or have remained inactive for an extended period.
✅ Good example: [email protected] (validated for syntax, domain existence, and activity regularly) ❌ Bad example: [email protected] (not checked or updated for several years) |
-
Comply with applicable laws and regulations
Finally, it’s essential that a list like this adheres to relevant regulations concerning email marketing and communication. Those refer to anti-spam laws (e.g., CAN-SPAM Act, GDPR). This includes providing recipients with clear opt-out mechanisms and respecting their preferences.
✅ Good example: [email protected] (provided with clear opt-out mechanism and respects recipient preferences) ❌ Bad example: [email protected] (ignores opt-out requests and continues sending unsolicited emails) |
Why is a valid email list important to have? Invalid mail addresses vs valid mail addresses
-
Lower bounce rates
A valid email list helps reduce bounce rates, which occur when emails are undeliverable.
Invalid or non-existent email addresses result in hard bounces, negatively impacting your sender reputation and potentially leading to email deliverability issues.
When you have a valid list, you can minimize bounce rates and improve your email deliverability.
💡 Practical example 💡
❌ Invalid addresses (500 contacts) with a bounce rate of 15%: 500 contacts * 15% = 75 bounces | ✅ Valid addresses (300 contacts) with a bounce rate of 2%: 300 contacts * 2% = 6 bounces |

Improved conversions
A valid email list consists of recipients who have willingly opted in or expressed interest in receiving your emails.
These individuals are more likely to engage with your content, click on links, and convert into customers or take desired actions.
Targeting a qualified and engaged audience increases the chances of achieving higher conversion rates.

💡 Practical example 💡
❌ Invalid email addresses (500 contacts) with a conversion rate of 2%: 500 contacts * 2% = 10 conversions | ✅ Valid addresses (300 contacts) with a conversion rate of 10%: 300 contacts * 10% = 30 conversions |
-
Enhanced engagement
With a valid email list, you can reach an audience genuinely interested in your offerings.
This increases the likelihood of recipients opening your emails, reading the content, and interacting with your messages.
Engaged subscribers are more likely to share your emails, provide feedback, and participate in surveys or promotions, fostering a stronger relationship with your brand.
💡 Practical example 💡
❌ Invalid addresses (500 contacts) with an open rate of 10%: 500 contacts * 10% = 50 opens | ✅ Valid addresses (300 contacts) with an open rate of 30%: 300 contacts * 30% = 90 opens |

Cost efficiency
Sending emails to invalid or inactive addresses not only wastes resources but can also lead to increased costs.
Many email service providers charge based on the number of subscribers or the volume of emails sent.
When you maintain a valid email list and eliminate non-functioning addresses, you can optimize your email marketing budget and focus on engaging a responsive audience.
💡 Practical example 💡
❌ Invalid addresses (500 contacts) at a cost of $0.05 per email: 500 contacts * $0.05 = $25 | ✅ Valid addresses (300 contacts) at a cost of $0.05 per email: 300 contacts * $0.05 = $15 |

Create a valid email address list for your next campaign in 4 steps
Creating a valid email address list for your next campaign involves 4 important steps.
Here’s a guide on how to do it effectively:
#1 Do an email syntax check
This process helps identify any addresses with improper syntax, such as missing “@” symbols or invalid characters.
💡Tip: use an email syntax checker or validator to make sure that the email addresses in your list are correctly formatted
#2 Remove disposable and catch-all emails from your lists
Disposable email addresses are temporary accounts that users create for short-term use.
On the other hand, catch-all addresses accept emails for any username at a particular domain.
These types of addresses are often associated with low engagement and deliverability issues.
💡Tip: consider using a service or tool that can identify and remove disposable and catch-all emails from your list to maintain a higher-quality audience
#3 Do a DNS lookup
A DNS lookup helps verify the existence and validity of the domain associated with each email address.
It checks if the domain has valid MX (Mail Exchanger) records, which indicate that the domain can receive emails.
Tools like MX Toolbox or online DNS lookup services can assist in this process.
💡Tip: conduct a DNS (Domain Name System) lookup for each domain in your email list
#4 Use an email verification tool
Finally, we highly recommend using an email verification service or tool to further validate the deliverability of your email addresses.
These tools go beyond syntax checking and DNS lookups to perform additional checks, such as mailbox existence and activity.
Email verification services like Bouncer can help you verify the deliverability and quality of your email list quickly and easily.

Frequently asked questions
Why is it important to validate email addresses?
Validating email addresses is crucial to ensure that your email campaigns reach their intended recipients. By validating email addresses, you can reduce bounce rates, improve sender reputation, and increase email deliverability. In order to build a valid email address list, it’s crucial to employ effective lead generation techniques, such as clear forms where people feel safe submitting their information, and tools that help you verify emails.
What does a valid email address consist of?
A valid email address consists of two parts: the email prefix and the domain. The email prefix is the part before the “@” symbol, while the domain represents the website or service hosting the email.
How do IP addresses relate to email deliverability?
IP addresses play a role in email deliverability as they are associated with mail servers. The reputation of the IP address used to send emails can impact deliverability, as email service providers may block or filter messages from IPs with a poor reputation.
What are acceptable email prefix formats?
Acceptable email prefix formats include alphanumeric characters (letters and numbers), periods, underscores, and hyphens. However, the prefix should not start or end with a period and should not contain consecutive periods.
What are valid email domains?
Valid email domains are legitimate and properly formatted domain names associated with email addresses. These domains should have valid top-level domains (TLDs) like .com, .net, or .org. The opposite of that is invalid email domains.
Are uppercase and lowercase letters important in email addresses?
No, email addresses are generally not case-sensitive. This means that “[email protected]” is considered the same as “[email protected]” or “[email protected]“.
What are valid email prefixes?
Valid email prefixes consist of alphanumeric characters (letters and numbers), periods, underscores, and hyphens. They should follow the correct format and adhere to the rules mentioned earlier.
