I've used Streak for + 3 years and has always been my go to. I've set it up for clients for sales, project management and my personal inbox.
Support is always willing to help and once you think you have mastered it, there is another hidden feature. (formulas in a CRM anyone?)
Make sure to hold an onboarding session for your team and commit, it will pay off.
Indispensable for managing hires and pipelines, been using it every day for months. However, it frequently takes a couple of seconds to load, and can take longer to retrieve old emails assigned to a box.
- Although it also includes the capability to manage sales, Nimble provides a useful 'Engagement Opportunities' panel which highlights opportunities for you to respond to contacts you've deemed as important via social media. I find it a useful complement to other CRM systems like Insightly and Salesforce.
