You are on the right track to consider one system for both marketing automation and Sales CRM. There are systems out there (not many) that allow you to intertwine sales and marketing pipelines. Revamp CRM and Agile CRM are good examples.
In its core, Revamp CRM allows you to automate segmentation, sales, and marketing under one roof. This enables you to notify or create tasks for your staff according to your lead/customer response to your marketing emails. Workflows also can update lead scores and send other emails. This kind of intertwined automation enables you to set lead nurturing on cruise control. It basically let you send relevant messages on a timely manner.
With the powerful integration to Invoicing and help desk systems such as Harvest, Freshbooks, Zendesk, HelpDesk and Zopim, you create a work flow that send emails and notify or create tasks for your team to act accordingly based on data coming from these systems as well as your notes, tags etc…
Dynamic and automated segmentation is your best friend to streamline most of your business scenarios.
In addition to the above, it comes integrated with 25+ business tools (Invoicing, helpdesk, chat, web forms, survey systems, etc...). It has open APIs so you can customize and extend based on your business needs. It also comes with:
- A well-integrated Gmail app that brings you contact info and notes from the CRM into your Gmail inbox and allows you to include Gmail communications into the contact profile in your CRM account.
- A Lead Clipper Chrome extension that lets you extract contact info from many web pages (LinkedIn etc...) into your CRM account.
Hope this helps. Let me know if you have any questions.
Wish you the best in your CRM hunt :)
