# Sellizer Reviews **Vendor:** Sellizer **Category:** [Sales Engagement Software](https://www.g2.com/categories/sales-engagement) **Average Rating:** 5.0/5.0 **Total Reviews:** 2 ## About Sellizer Sellizer is a sales engagement tool that gives you full visibility into what happens after you send a proposal. Instead of guessing whether a prospect read your offer, you see the exact moment they opened it, how long they spent on each page, which sections they revisited, and who else they shared it with. Real-time notifications let your sales team follow up at the highest-intent moment - when the prospect is actively reading. Automated, scheduled follow-ups keep deals moving without manual effort, and detailed engagement analytics help you identify which proposals, pages, and pricing structures actually convert. Sellizer integrates with leading CRMs including HubSpot, Pipedrive, Salesforce, Zoho, Monday, Dynamics 365, Raynet, and Firmao, so proposal activity flows directly into your sales workflow. Built for B2B sales teams that send proposals as PDFs and want to close more deals based on data, not guesswork. ## Sellizer Reviews ### 1. Clear proposal engagement signals helping us time follow-ups better **Rating:** 5.0/5.0 stars **Reviewed by:** Verified User in Computer Software | Small-Business (50 or fewer emp.) **Reviewed Date:** May 11, 2026 **What do you like best about Sellizer?** The main thing I get from Sellizer is knowing whether a prospect is still engaged with our offer or not. When I see someone opening the proposal a second or third time, I know the deal is alive, and they're still considering it. It's a simple signal but a useful one - without it, you're just guessing whether to follow up or move on. I also like seeing which sections of the offer get the most attention and which get skipped. We don't always act on it directly, but over time, it gives us a sense of what to refine in our proposal structure and how we present our portfolio. **What do you dislike about Sellizer?** It's a tool that not every team will be able to fully leverage - getting the most out of it depends on your internal sales processes and habits. If your team isn't set up to act on engagement signals in real time, some of the value will go unused. **What problems is Sellizer solving and how is that benefiting you?** The biggest problem it solves is the black hole that usually follows sending a proposal - you send the PDF, and then you have no idea what's happening on the other side. Sellizer gives you at least some visibility: who's opening it, how often, and what they're looking at. In practice, this helps with two things. First, prioritization - knowing which deals are still warm and worth following up on. Second, predictability - over time, you start to get a better feel for whether a proposal is going to convert based on how the prospect engages with it. It doesn't replace good sales work, but it adds a useful data layer on top of it. ### 2. Proposal Tracking That Builds Confidence and Peace of Mind **Rating:** 5.0/5.0 stars **Reviewed by:** Tommy P. | Founder, Small-Business (50 or fewer emp.) **Reviewed Date:** May 12, 2026 **What do you like best about Sellizer?** It gives me confidence in my own work. When I send a proposal, I'm not left wondering whether it landed in someone's inbox and got ignored. I can see that the client actually opened it, went through it, and spent time with it. That comfort - knowing the effort didn't go to waste - is honestly the biggest thing for me. **What do you dislike about Sellizer?** Nothing major comes to mind. There are small things I'd tweak here and there, but nothing that gets in the way of how I use it day to day. **What problems is Sellizer solving and how is that benefiting you?** It removes the uncertainty that usually comes after sending a proposal. Instead of guessing whether the client is interested, I know - and that lets me follow up at the right moment, with the right energy, instead of writing nervous "just checking in" emails. - [View Sellizer pricing details and edition comparison](https://www.g2.com/products/sellizer-sellizer/reviews?section=pricing&secure%5Bexpires_at%5D=2026-05-14+06%3A46%3A05+-0500&secure%5Bsession_id%5D=87de5ca5-dacc-451e-af54-dd055a7c4f31&secure%5Btoken%5D=2c118f315720bd6d1eb188129bb6100f798e7c64b51cfec23e00c1119eaa8e18&format=llm_user) ## Sellizer Features **Integrated Workflows** - Task Management - Email Tracking/Automation - Calls and Voice - Other Outreach Options - CRM Integration - Calendar - Shared Records **Repeatability and Reportability** - Content Management - Workflow Management - Workflow Performance - Sales Coaching and Insights - Gamification **AI and Automation** - Lead Prioritization - Lead Scoring - Best Time of Day Scheduling - Buyer Intelligence - Machine Learning **Generative AI** - AI Text Generation **Agentic AI - Sales Engagement** - Autonomous Task Execution - Multi-step Planning - Cross-system Integration - Adaptive Learning - Natural Language Interaction - Proactive Assistance - Decision Making ## Top Sellizer Alternatives - [Agentforce Sales (formerly Salesforce Sales Cloud)](https://www.g2.com/products/agentforce-sales-formerly-salesforce-sales-cloud/reviews) - 4.4/5.0 (24,579 reviews) - [ActiveCampaign](https://www.g2.com/products/activecampaign/reviews) - 4.4/5.0 (14,137 reviews) - [HubSpot Sales Hub](https://www.g2.com/products/hubspot-sales-hub/reviews) - 4.4/5.0 (13,155 reviews)
