If you are looking for a cool business tool, then I recommend the salesforce calendar. This way you can share your timeslots on your Salesforce calendar so you can schedule an appointment in seconds.
Schedule meetings easily.
No more constant back and forth movements, no more scheduling. Pick multiple slots on your calendar and insert interactive timeslots into your email for your prospects and prospects to choose from. Or, even easier, just share your full accessibility as a link and let your leads choose the best time for them.
