Hunter helps you find professional email addresses quickly and easily. At the time of this writing they offered 25 free searches per month. Registration is required to use this app. If you’re in sales, you’ll definitely want to check it out.
Calendly is an online scheduling tool that lets people self-schedule time on your digital calendar based on your open availability. It’s one of my favorite Internet marketing tools because it takes friction out of scheduling meetings and reduces back-and-forth emails.
