Breezemail

What is Breezemail?
Breezemail is an email assistant that sits on top of Gmail or Outlook and sorts mail with AI labels. It keeps messages it judges important in your inbox and files everything else into smart categories you define in plain language, powered by ChatGPT queries instead of manual filter rules.
Unlike traditional inbox rules that need operators and exact sender matches, Breezemail lets you write categories like "all emails about finance and investing" and applies them across new mail. It also ships preset buckets for newsletters, purchases, social, promotions, and travel, and it picks the most specific label when an email fits more than one.
The product targets professionals drowning in newsletters and automated mail who still need human messages surfaced quickly. Pricing is $12 per month after a 7-day trial with no card up front, and the privacy page states Breezemail does not store or sell mailbox content, routing processing to the ChatGPT API only.
Opnbx.ai

What is Opnbx.ai?
Opnbx.ai is a B2B sales intelligence platform built around what the company calls Precision Prospecting. It gives sales and marketing teams a unified data layer to spot which accounts in their market are worth pursuing right now. The product focuses on ICP validation, intelligent segmentation, and account-level research rather than generic firmographic lists. Teams log in through app.opnbx.ai after booking a demo through the marketing site.
Most intent data vendors sell broad market signals that every competitor can buy. Opnbx.ai tries to correlate signals from your own closed-won deals with live account activity, then scores and prioritizes companies against that custom model. The homepage positions it as a replacement for stitching together a Franken-Stack of tools like 6sense, Clay, Bombora, and ZoomInfo. That trade-off is narrower fit modeling in one platform instead of buying the same commoditized feeds everyone else has.
It targets sales leaders, RevOps teams, and individual reps at B2B companies running outbound or pipeline development motions. Integrations listed on the site include Outreach, HubSpot, Salesforce, Salesloft, and Apollo.io. Customer testimonials on the homepage come from teams at Datavolo, Vial, Descope, and Pangia who cite faster account research and higher conversion rates after onboarding.
