Our 12-stage comprehensive

List cleaning process

1

Deduplication

Remove duplicate email addresses so your list contains only unique addresses, reducing unsubscription rates significantly.

2

Domain

Thorough scan of all domains to classify parked, invalid, or non-working domains. Optimises your open rates.

3

Spamtrap

Each email scanned against our spam trap indicators derived from provider databases. Prevents IP blacklisting.

4

Complainers

Match against our complainers database. If found, the email is set aside to inform you about the risk.

5

Risk

Identify high-risk keywords and TLDs across millions of email addresses. Intelligently separate risky addresses.

6

Syntax

Invalid syntax is automatically handled. Accurately determine what is a properly formatted email address.

7

MTA

Check MX records validity for each email. All non-working and invalid MX records are efficiently removed.

8

Suppressed Email

Have emails deemed unsafe or complained before? We ensure your new list excludes these addresses.

9

Unbalanced Delimiter

Intelligent identification of email addresses with out-of-balance delimiters using complex algorithms.

10

Mailbox Error

Real-time MTA responses classify emails with mailbox errors like "Mailbox full" as soft bounces.

11

Custom TLDs

Remove specific TLDs you want excluded. Our system identifies and separates unwanted top-level domains.

12

SEVL Score

Quality score for your mailing list. A valid email doesn't always mean it's a good email to send to.
