It’s difficult to achieve timely responses (with actionable data) from email and phone campaigns. There’s too much email for sure.
I learned about Hustle.com recently. I’ve received a lot of texts based on their platform (mainly from political campaigns). Hustle’s peer-to-peer texting platform has enormous potential for businesses, campaigns, and networking groups which struggle with engagement. Emails and phone calls are less effective in our age of nonstop communication.
