Economic but little less accurate with results. **Rating:** 2.0/5.0 stars **Reviewed by:** Vikrant B. | Director of Digital and AI Customer experience, Information Technology and Services, Small-Business (50 or fewer emp.) **Reviewed Date:** October 09, 2022 **What do you like best about Atomic Mail Verifier?** The results are quick, and the user interface is pretty neat. There are not many buttons and functions that make it easy to use. It has little section where we see the analytics of bounce/undelivered vs delivered. **What do you dislike about Atomic Mail Verifier?** It uses port 25 to scan, which is a hassle. It burns the IP address, which is one of this software's most harmful features. Often the results are not accurate. We get more uncertain data means it is neither valid nor invalid. **What problems is Atomic Mail Verifier solving and how is that benefiting you?** It appears that it is solving the problem, but it is not. We have only purchased this software for the price we were offered. I use it to match the results given out by other mail verifier software. As it burns my IP address, I don't use it often but once a month. ### 2. Doesn't work very well anymore if your port 25 is closed. **Rating:** 2.0/5.0 stars **Reviewed by:** Yacine H. | Vice President - Client Relations, Small-Business (50 or fewer emp.) **Reviewed Date:** September 04, 2019 **What do you like best about Atomic Mail Verifier?** It used to be the most awesome, best and least expensive email verifier on the market. All the other companies charge your per email checked, and this is a one time fee. The software works FAST, I'm able to triple-verify 10,000 emails in less than 2 hours. The sending process couldn't keep up. It works really well and does check many different parameters, removing spam traps and throwing away old emails from your lists. **What do you dislike about Atomic Mail Verifier?** For the past year there is a new problem which is that it doesn't work anymore if your port 25 is closed, which is the case for most networks (my office, my university, my library, my home). The only way around this is the put it on a dodgy virtual private server, but we use google apps in our organization which ALSO has port 25 closed. This means we're unable to use this amazing software. **Recommendations to others considering Atomic Mail Verifier:** If you have a network with port 25 open, you're in luck and Atomic Mail Verifier is the best investment you will ever make. **What problems is Atomic Mail Verifier solving and how is that benefiting you?** Updating our sales list : removing old emails which are not valid anymore. Gathering data : checking the lists of leads we receive before prospecting. ### 3. good not always effective **Rating:** 2.0/5.0 stars **Reviewed by:** Davis T. | Event Manager IR / Executive Assistant , Financial Services, Enterprise (> 1000 emp.) **Reviewed Date:** September 22, 2018 **What do you like best about Atomic Mail Verifier?** its very easy to use, simple stream line, easy interface not hassle or bs **What do you dislike about Atomic Mail Verifier?** not always as effective as i want it to be but very good **Recommendations to others considering Atomic Mail Verifier:** I think this platform is a good try for anyone looking to clean out fake emails for business reasons especially related to marketing to general large email blasts **What problems is Atomic Mail Verifier solving and how is that benefiting you?** to get rid of fake emails from email databases before marketing campaigns ## Atomic Mail Verifier Discussions - [What is the best email verification tool?](https://www.g2.com/discussions/atomic-mail-verifier-what-is-the-best-email-verification-tool) - [What are email verification tools?](https://www.g2.com/discussions/what-are-email-verification-tools) - [How does email verifier work?](https://www.g2.com/discussions/how-does-email-verifier-work) - [How do I use Atomic Mail Verifier?](https://www.g2.com/discussions/how-do-i-use-atomic-mail-verifier) - [View Atomic Mail Verifier pricing details and edition comparison](https://www.g2.com/products/atomic-mail-verifier/reviews?filters%5Bnps_score%5D%5B%5D=2§ion=pricing&secure%5Bexpires_at%5D=2026-08-12+19%3A12%3A08+-0500&secure%5Bsession_id%5D=9830203c-d0e2-4c49-b666-4afe4c46d90b&secure%5Btoken%5D=7de9fa69d273944c66c7e9a5cb7aaa902f6d1b49f67921d854e8f44fe43989e6&format=llm_user) ## Atomic Mail Verifier Features **Additional Functionality** - Third-Party Integrations - To-Do List - @mentions - Single Sign On - File Management - Activity Dashboard - Drag & Drop - Alerts/Notifications - Prioritization - Access Controls/Permissions - Screen Sharing - Content Management - Brainstorming - AI Copilot - File Transfer - Calendar Management - Status Tracking - Real-Time Notifications - Version Control - Task Management - Activity Tracking - Real Time Editing - Communication Management - Chat/Messaging - Tagging - Generative AI - Assignment Management - Task Scheduling - Project Management - Collaboration Tools - Workflow Management - Secure Data Storage - File Sharing - Document Storage - Task Progress Tracking - Discussions/Forums - Commenting/Notes - Reporting & Statistics - Contact Management - Video Conferencing - Progress Tracking - Mobile Access - API - Document Management - Customizable Branding **Generative AI** - AI Text Generation - AI Text-to-Speech - Generative AI **Agentic AI - Email Verification** - Decision Making **Additional Functionality** - Email Management - CRM - Fraud Detection - Data Verification - Lead Management - Contact Database - Spam Detection - A/B Testing - Email Distribution - Disposable Email Detection - Activity Dashboard - Unsubscribe Database - Syntax Check - AI Copilot - Data Import/Export - Spam Analysis - Subscription Management - Campaign Segmentation - Secure Data Storage - Third-Party Integrations - Duplicate Detection - Email Templates - Real-Time Monitoring - Contact Management - Anti Spam - Recipient Validation - Drag & Drop - Delivery Tracking - Email Marketing - Email Alerts - Bulk Email Verification - Drip Campaigns - Activity Tracking - Data Capture and Transfer - Bounce Rate Analysis - Catch-all Server Detection - Customer Database - Single Email Verification - Monitoring - Bulk Send - Spam Blocker - Mailing List Management - Email Tracking - Reporting & Statistics - File Transfer - Real-Time Data - Real-Time Analytics - Compliance Management - API - Domain Check - Email Address Extraction ## Top Atomic Mail Verifier Alternatives - [GTM Workspace - Powered by ZoomInfo](https://www.g2.com/products/gtm-workspace-powered-by-zoominfo/reviews) - 4.5/5.0 (8,874 reviews) - [MailerLite](https://www.g2.com/products/mailerlite/reviews) - 4.6/5.0 (1,097 reviews) - [Reoon Email Verifier](https://www.g2.com/products/reoon-email-verifier/reviews) - 4.8/5.0 (1,011 reviews)
