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.

Emailmarker - Overview

EmailMarker is a reliable email verification service that provides 24/7/365 customer support, a user-friendly dashboard with a graphical view of API verification, and advanced algorithms for identifying invalid, inactive, or fake email addresses and removing them. While it currently offers integration with Mailchimp, its unique features make it a top choice for businesses looking to improve their email deliverability and reputation.

Pros

Cost-Effective
As the cheapest email verification service, EmailMarker charges $21 to verify 10,000 emails. It has made its palace inside LCA's recommended top 10 affordable vendors. Its minimum order value is $3 for 1,000 credits.
Fast Process
Also, EmailMarker is good at verifying email addresses quickly. During its audit, we received the resultant file for 10K emails in just 150 minutes. Its turnaround time is half of the industry average, which is 582 minutes for 10K emails. As a result of its speedy process, it was ranked among LCA's top 10 fastest email verification programs.
Free Email Credits
In addition, EmailMarker offers 150 free credits for one-time use. You can use those credits for either single- or bulk-email verification.
Good Customer Support
Live chat, email, and phone support are all provided by EmailMarker. It offers live chat support 24/7; however, sometimes it takes a while for it to respond to its users. Its email support is also excellent as they provide in-depth and detailed answers to your technical queries within 4 to 5 hours of sending your email.

Cons

Less Accurate
When we audited EmailMarker, we achieved an accuracy of 74%, which is lower than the industry standard of 96%. Also, when we audited it, it failed to detect role-based email addresses. According to LCA's audited 35+ email verifiers, it ranks 17th for accuracy.
