TowerData - Overview

With TowerData, email marketers can engage customers behind the email address. In addition to accurate email verification, TowerData also offers email intelligence and email append services. If you are looking for intelligent email verification, TowerData is the best choice.

Pros

Quick Verification Process
TowerData is also one of the fastest tools for email verification as it verifies 10K email addresses in 400 minutes, much faster than the industry standard turnaround times of 498 minutes. In terms of verification speed, it cannot compete with the other ten vendors, such as MyEmailVerifier and QuickEmailVerification.
Free Trials & Credits
TowerData also provides its users with free credits to test its interface and verification capabilities.
Good Integration Facility
With TowerData, you can integrate 16 other applications, including MailChimp, ConstantContact, Campaign Monitor, etc., and bring your data automatically from these platforms and manage your marketing activities in one place.
Excellent Customer Support
In addition to email and phone support, TowerData also offers live chat support during business hours, which are Monday through Friday from 9 a.m. to 5 p.m. Eastern Standard Time. Additionally, you can schedule a meeting with a representative by picking a time and date from its calendar. Therefore, its customer support is exceptional.

Cons

Expensive
Among 30+ email verification tools audited by LCA, TowerData is one of the most expensive. The cost of 10K email verification is $100, about six times more than other email verification tools, such as RemoveBounce and DeBounce, which cost just $15 for 10K. According to TowerData's latest audit report, it ranks 28th in the race for most affordable email verifiers.
Less Accurate
As per industry standards, TowerData's accuracy falls behind. In our audit, we achieved only 74% accuracy, which is below the industry standard of 96%. Additionally, it failed to detect catch-all email addresses. In our audit of other email verifiers, TowerData ranks 17th for accuracy.

With TowerData Email Append, you can keep in contact with direct mail subscribers and grow your email list at the same time.

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.
