Didn't allow my individual emails 36 hours after the inital challenge **Rating:** 2.0/5.0 stars **Reviewed by:** Steve 🔸 S. | President, Small-Business (50 or fewer emp.) **Reviewed Date:** February 24, 2020 **What do you like best about GMass?** Nothing yet... facing rejection after purchasing the extension for most of my grouped emails. **What do you dislike about GMass?** I had never sent any mass emails to my Gmail list. When I did for my upcoming SpeakerTalks event I was surprised I got rejections. I, therefore, purchased the Mass Gmail application and expected immediate results from that subscription. I am 36 hours later and struggling to be able to send any group emails without rejection. Maybe it will get better and allow me to email my people for this speaking event that will help them grow their business. **What problems is GMass solving and how is that benefiting you?** I want to be able to notify my groups of my events in a timely fashion to get them all the information to help them build their speaking and author business. So far, it has not worked and therefore no benefits have been realized. ## GMass Discussions - [Is there a way to learn how to use GMass?](https://www.g2.com/discussions/33387-is-there-a-way-to-learn-how-to-use-gmass) - 2 comments, 1 upvote - [which gmass subscription should i buy?](https://www.g2.com/discussions/31404-which-gmass-subscription-should-i-buy) - 1 comment, 1 upvote - [Emails from one particular server are not going through - how do I find out why or solve the problem](https://www.g2.com/discussions/emails-from-one-particular-server-are-not-going-through-how-do-i-find-out-why-or-solve-the-problem) - 1 comment, 1 upvote - [Is that possible for gmass software to integrate with landing page builder?](https://www.g2.com/discussions/is-that-possible-for-gmass-software-to-integrate-with-landing-page-builder) - 1 comment, 1 upvote - [Can it be integrated with ClickFunnels and use with a Chatbot](https://www.g2.com/discussions/12612-can-it-be-integrated-with-clickfunnels-and-use-with-a-chatbot) - 1 comment, 1 upvote - [View GMass pricing details and edition comparison](https://www.g2.com/products/gmass/reviews?filters%5Bnps_score%5D%5B%5D=2§ion=pricing&secure%5Bexpires_at%5D=2026-08-13+11%3A08%3A53+-0500&secure%5Bsession_id%5D=fded1ea0-ca7f-4c0d-88d9-2fdf847f769d&secure%5Btoken%5D=47001447933e436ac587277bc65760cf0e4ef08b3cc1b9e154f7379bf471189f&format=llm_user) ## GMass Integrations - [Twilio SendGrid Email API](https://www.g2.com/products/twilio-sendgrid-email-api/reviews) - [Zapier](https://www.g2.com/products/zapier/reviews) ## GMass Features **Email Marketing** - Email and Mobile Preview - Manage Email Lists - High-Volume Sending - Building and Personalizing Emails - Sending Outbound Emails - Manage Email Deliverability - Automated Email Responses - Multi-user Account - Surveys **Agentic AI - Email Tracking** - Autonomous Task Execution - Multi-step Planning - Cross-system Integration - Adaptive Learning - Natural Language Interaction - Proactive Assistance - Decision Making **Analytics** - Open Rates - Link Activity - Attachment Activity **Customizations** - Email Platform Integration - Email Scheduling - Real-Time Notifications - Email Categorization - Templates - Third-Party Integrations **Generative AI** - AI Text Generation - Generative AI **Additional Functionality** - Contact Management - Email Marketing - Drag & Drop - Drip Campaigns - Workflow Management - Customizable Fields - Monitoring - CRM - Team Management - Click Tracking - Subscription Management - Activity Dashboard - API - Location Tracking - Customer Segmentation - Geolocation - Customizable Branding - Activity Tracking - Data Import/Export - Mailing List Management - Campaign Management - Email Management - Audience Targeting - Reporting/Analytics - AI Copilot - Email Distribution - Email Reminders - Autoresponders - Engagement Tracking - Event Triggered Actions **Reporting & Analytics** - A/B Testing - Basic Reporting **Generative AI** - AI Text Generation - AI Text Summarization - Generative AI **Agentic AI - Email Marketing** - Autonomous Task Execution - Autonomous Task Execution - Multi-step Planning - Cross-system Integration - Cross-system Integration **Integration** - Data Import & Export Tools - Integration APIs - Breadth of Partner Applications - CRM Integration - Social Media Integration - E-Commerce Integration - Third-Party Integrations **Additional Functionality** - Personalization - Autoresponders - Customer Segmentation - Newsletter Management - AI Copilot - WYSIWYG Editor - Engagement Tracking - Preview Functionality - Email Tracking - Email Campaign Management - Landing Pages/Web Forms - Customizable Branding - Lead Capture - Mobile Optimization - Customer Journey Mapping - ROI Tracking - Activity Dashboard - Customizable Fields - Reporting/Analytics - Click Tracking - List Management - GDPR Compliance - Subscriber Management - Email Sequences - Campaign Scheduling - Event Triggered Actions - Multi-Language - Template Management - Customizable CTAs - Real-Time Analytics - Dynamic Content - CAN-SPAM Compliance - Multi-Channel Marketing - HTML Editor - Contact Management - Drip Campaigns - Campaign Analytics - Product Recommendations - Image Library - Workflow Automation ## Top GMass Alternatives - [Brevo Marketing Platform](https://www.g2.com/products/brevo-marketing-platform/reviews) - 4.5/5.0 (2,481 reviews) - [Saleshandy](https://www.g2.com/products/saleshandy/reviews) - 4.6/5.0 (799 reviews) - [Intuit Mailchimp Email Marketing](https://www.g2.com/products/intuit-mailchimp-email-marketing/reviews) - 4.3/5.0 (12,675 reviews)
