Also listed in Email Tracking, Sales Analytics, AI Sales Assistant, Revenue Operations & Intelligence (RO&I), Conversation Intelligence

The greatest benefit of Substrata is its emphasis on Social Signal Intelligence and the application of that intelligence to the sales communication and relationships.
This platform offers our organization information beyond the scope of traditional CRMs including sentiment, engagement, communication dynamics, relationship dynamics, authority, trust, and sales team performance.
The Signals functionality allows us to gain additional insight into changes in engagement and relationship dynamics.
Q for Email enables our sales representatives to think twice about their written communication.
Authority Zone provides an additional perspective regarding communication confidence, credibility, and authority.
Performance & Team Q offers insights about the entire sales team for sales management purposes.
The value of this whole platform lies in the emphasis on human aspects of B2B sales. CRMs are good at collecting activities and information on deals but do not always reveal what is happening inside the relationship itself. Review collected by and hosted on G2.com.

Simple All-in-One Marketing Software. With awesome software tools backed by a dedicated support team to make every part of your marketing more effective.
Also listed in Online Form Builder, Landing Page Builders, A/B Testing, Email Tracking, CRM
We started using EngageBay mainly to get our contacts and email communication in one place. So far, it has worked well for what we need.
The contact management is probably the part we use most. It's nice being able to look up a contact and see the information and activity without having to search through different places. We also use email broadcasts for sending updates to different groups of contacts.
The email templates are another feature I use quite often. Once you have a few templates ready, it saves a lot of time because you're not creating the same type of email again and again. We also use sequences for follow-ups, which has been useful when there are a lot of prospects to stay in touch with. It has made our overall email process more organized.

The part that works best for me is that Lead Explorer, Lead Validation, Email Outreach, LinkedIn Automation, and CRM Manager sit in the same place. I can build a list, verify the contacts before sending, run the email sequence, layer LinkedIn touches on top, and track the deal without exporting anything. The verification step in particular saves me from burning sender reputation on bad addresses, and having activity land back in the CRM automatically means my pipeline actually reflects what I did that week.
