Want to know when people open your emails? If you have Microsoft Outlook, you could use its Read and Delivery Request, but what if the recipient declines to send it? You'd never know if they opened or read your email. What if you don't have Microsoft Outlook? Now there's a solution: HubSpot. It works in the background, transparent to the recipient so there's nothing they need to respond to. To find out more, see the HubSpot website.
I love technology and how it enhances our lives! Just think, without the Apollo moon missions, we might not have calculators! Imagine!!
