8 Email App Business Success Stories [2023]
Here are some real life success stories of starting a email app business:
1. Mailman ($360K/year)
This founder has built 25+ side projects. Most of them failed but a few brought in some revenue. After failing small and big over two dozen times, he had one product that investors wanted to invest money in, and after five years of growing it, sold it, and took some time off from making stuff. He started advising and investing in startups, especially crypto startups.
To find time from all the chaos happening in his inbox, he wrote a small script that would make sure that emails landed in his inbox only every four hours, in batches. Nothing comes in between. He used this script to find time to find good ideas that he could be building next.
That’s when he saw a tweet from Andrew Wilkinson (Dribble owner), and he immediately emailed him with the script and a video tutorial. His reply was, “What if we make this into a business?”
How much they make: $360K/year
How much did it cost to start: $30K
Current team size: 5

Mailman, a tool that allows users to control when and what emails should land in their inbox, is a year-old company bringing in approximately $30k in MRR, while its upcoming features will improve users’ newsletter-reading experience and automate redundant tasks.




2. Mutant Mail ($24K/year)
Abhishek, the founder of Mutant Mail, came up with the idea for his business after facing a server outage and receiving a DMCA complaint due to email monitoring negligence. Realizing the need for a solution to easily manage multiple domain emails, Abhishek and his team developed Mutant Mail, the only server-side solution to this problem. Within two weeks of its soft launch, they acquired 10 paid customers, and within five days of their AppSumo launch, they gained another 100 paid customers.
