Processes of email verification:

1. Email Deduplication: This allows your list to contain only unique addresses and thereby reduce your unsubscription rate significantly. It is the process by which the processing tool gathers strings of data, converts those strings into hash codes, compares those hash code values, identifying matching records and flagging one as unique and the others as duplicates. This process also  removes improperly formatted email addresses, according to IETF standards.

2. Domain Check: Running a thorough scan of all the domains on your mailing list, then scan them and classify them as being parked/invalid/non-working domains. If a domain is found to be invalid, it then marks the corresponding email address as invalid. This helps in optimising your open rates.The domain check also verifies the DNS entries of an email address.

3. Role-Based Account Detection: This process detects and flags addresses on each email address on your list by scanning them against spam trap indicators. Its the most comprehensive method to avoid getting your IP’s blacklisted

4. Disposable Email Address (DEA) Detection: Detecting a disposable email address is not so straightforward. A naïve approach is to compile a list of disposable email address providers.  Disposable email address (DEA for short), often called a throwaway email address, is a temporary email address that masks user’s real email address.These are usually used for signup forms or to bypass login forms which require a valid email address. In a more detailed form, if a user gets a disposable email address and uses it to register on your website, you as a business, instead of getting user’s real email address, get user disposable email address.

5. Honeypot/ Spam Trap Detection: A honeypot/Spam Trap are email address traps. The bulk of the spamtraps and honeypots today are from dormant email accounts and/or closed domains.  The logic is simple: a ‘dead email inbox can’t opt-in to receive email’, so anyone sending email to one of these spamtrap addresses is likely sending unsolicited email. Using one of these emails, you will be immediately considered a spammer. ISPs review their list of email boxes regularly and disable accounts that have been inactive for a long period of time.

After a period of inactivity, ISPs re-activate these addresses and convert them into spamtraps/honeypots in an attempt to catch spammers.

6. Syntax: Any email address with invalid syntax is automatically taken care of. You don’t need to worry about our system skipping these addresses. It will accurately determine what is an email address and what isn’t.

7. Unbalance Delimeter: An system intelligent enough to identify email addresses containing out of balance delimiters.

8. Checking DNSBLs and URI DNSBLs for blacklisting: Mailbox providers and filtering companies do not leverage inbox placement on every blacklist. They typically combine data from various public blacklists, as well as data from their own networks, to determine your credibility as a sender.

9. Final Verification: This phase performs deep-level extended SMTP verifications on each email address. The addresses will be pinged for mailbox existence without sending an actual email to the inbox.
