What is Email List Cleaning?
Email list cleaning is the process of improving the accuracy and quality of an email list. It involves verifying the format of each email address to ensure it conforms to standard formats, removing invalid email addresses, and removing email addresses that belong to known spam traps or complainers.
The process also involves checking MX records to ensure the domain of the email address exists and is set up to receive email. This helps to maintain the integrity of the email list and improve email deliverability. A clean email list leads to higher open and click-through rates, which can result in a better return on investment for email marketing efforts.
Why is It Important?
Email list cleaning is an essential aspect of email marketing that involves verifying and updating the email addresses on a mailing list. It helps ensure that the email list contains accurate, up-to-date, and valid email addresses. Having a clean email list has numerous benefits and can significantly impact the success of an email marketing campaign.
In general, “Email List Cleaning” is important because:
- Increases email deliverability: by removing invalid email addresses, email service providers are less likely to flag a mailing list as spam.

Bulk Email Verification service checks the email addresses in the list in 4 steps and shows the invalid ones in the result file. The points that the service checks for email validation are: “Email Format,” “MX Records,” “Database of Complainers and Spam Traps,” and “Email Ping Response.”
Checking Email Format
Outscraper first checks the format of the email address. A valid email format consists of two parts, separated by the @ symbol: the local part and the domain.
The local part can have uppercase and lowercase letters, numbers, and special characters, such as (dot), – (dash), _ (underscore), and + (plus). And the domain part must have a valid domain name registered with a domain registrar.
Checking MX Records
MX records, also known as Mail Exchange records, are DNS (Domain Name System) records that specify the mail server responsible for accepting email messages on behalf of a recipient’s domain.
Inaccurate or missing MX records can result in undeliverable emails or delays in email delivery. Accurate MX records ensure that emails are routed to the correct mail server and delivered to the recipient’s inbox. Outscraper Bulk Email Verification service validates the records of the entire email list with its built-in online MX record checker tool.
Checking Database of Complainers and Spam Traps
Complainers are email addresses that have marked previous emails as spam. In contrast, spam traps are fake email addresses set up by ISPs or anti-spam organizations to catch and identify spammers. If you send emails to these addresses, it can be a problem because it shows that you are sending spam. It’s important to keep your email list clean and not send emails to these addresses.
Emails tested in the Outscraper Bulk Email Verification service are searched in the complainers and spam traps database, and if found, they are marked in the result file.
Pinging Emails for Deliverability
Verifying an email address through pinging is an efficient method to determine if it’s active without sending a real email. This process involves connecting to the email’s SMTP server and checking for the existence of its MX (mail exchange) records and the email address itself. If the SMTP server is accessible, the pinging will be successful. If not, the process will take too long or fail.
Outscraper also pings all email addresses in the list one by one to verify emails. According to the ping response, it adds the status of the email address to the result file in a positive or negative way.
