Advanced Feature's Comparision

EmailVerifierApp - Advanced Features

Deduplication: Reduce unsubscribe rates by deduplicating your mailing list. This allows your list to contain only unique addresses and thus reduces your unsubscribe rate.
Domain: Our tool scans all the domains on your mailing list and classifies them according to whether they are parked, invalid, or non-working.
Spamtrap: The most comprehensive method to avoid getting your IP addresses blacklisted is to scan each email address on your list against our spam trap indicators.
Complainers: Email addresses on your mailing list are scanned for matches against our database.
Complainers database: If a match is found, that email will automatically be set aside to inform you of the risk.
Risk: Detects high-risk keywords and TLDs in millions of email addresses. It will intelligently separate these out for you.
Syntax: Email addresses with invalid syntax are automatically handled by their system. You do not have to worry about their system skipping these addresses. It will accurately determine what is an email address and what is not.
MTA: Every email address is checked for the validity of its MX records. Non-working and invalid MX records are dealt with efficiently.
Suppressed Email: They will ensure that your new list doesn't contain any email addresses that have been deemed unsafe or invalid or have been reported before.
Unbalanced Delimiter: Their algorithm is complex enough to find email addresses containing out-of-balance delimiters. Their tool is intelligent enough to identify these records.
Mailbox Error: With real-time responses from MTAs, it can easily classify and segment email addresses with mailbox errors, such as "Mailbox full" (soft bounce).
Custom TLDs: If you want specific custom TLDs removed from your mailing list? They can help. Their system can identify and remove unwanted TLDs.
EV Score: The EV Score shows the quality of the email address you have on your list. Just because it's valid doesn't mean it's a good one to send to.
