Toutapp allows you to track your email leads in real time and seems to work best on Gmail although it can also be used for social media and phone marketing. Sales reps can collaborate appointments via calendar and communicate via integrated phone or email networks. Toutapp has plenty of metrics opportunities and integrates with various workflow apps. Some reviewers not that the interface needs time to get used to, but appreciate the single page command centre and live feeds. Fairly competitive pro price plan, but you can also ask for a custom pack.
