Back in early 2025, I was a freelance digital marketer and lead generation specialist, bringing in about $2,400 a month, running a small agency out of Rajshahi, Bangladesh. Cold outreach was how I mostly got new business, but putting together good B2B email lists was a real headache and cost a lot. I ended up using a bunch of free tools and cheap databases that just gave me a lot of bounces, spam complaints, and hardly any replies. Finding good, verified contacts was either too expensive (with monthly fees) or the lists were too small to really grow my campaigns. I spent hours chasing leads, my emails often didn't even land, and getting new clients was super slow. My earnings just stayed the same, while others with better info were landing more clients.
Then I stumbled upon Happierleads B2B Contacts Database on AppSumo. I went ahead and bought the lifetime deal. Five months have passed since then, and now I can instantly get my hands on over 175 million verified B2B contacts across 156 different industries. I can download clean lists as CSVs in just seconds, run big campaigns that actually reach people, and my monthly income has shot up to $8,900, all while working only 25 to 28 hours a week. Honestly, Happierleads turned into my secret weapon for finding leads.

How Happierleads Changed Things for Me Over 5 Months
Here's how things unfolded over five months:
In Month 1, I started by downloading my first targeted lists for both local and international markets. I launched some initial cold email campaigns and saw much better reply rates right away. That added an extra $1,800 to my earnings, bringing my monthly income up to $4,200.
By Month 2, I branched out into new industries, taking advantage of the database with its 156 categories. I managed to close several valuable ongoing lead generation contracts, pushing my income to $5,900.
During Months 3 and 4, I set up automated outreach systems, using fresh exports every single week. This let me run campaigns for many clients all at once, and my income reached $7,500.
By Month 5, I was handling lead generation for 12 active clients, plus my own projects. I hit a steady $8,900 a month, all while keeping my workweek to just 25–28 hours.
Overall, my revenue jumped from $2,400 to $8,900 a month – that's a 271% increase. My campaigns performed a lot better, with much higher reply and conversion rates. I even started offering new, premium “Unlimited Verified Leads” packages to clients.
What I Got Back for My Investment (First 5 Months)
Looking at the return on my investment over the first five months:
The Happierleads lifetime deal was a one-time purchase on AppSumo, which gave me unlimited downloads forever. I saved so much time on lead research, which I figure is worth about $11,000 in recovered hours. Because I could run more campaigns and land more ongoing clients, I saw an extra $6,500 a month in recurring revenue. All in all, my net gain over these five months was more than $47,000 (after taking out the initial cost). That means for every dollar I spent, I got back over 155 times that much in just the first five months.

Just a couple of small things to keep in mind: because the database is so huge, you really need to be smart about how you use your filters so you don't end up with lists that are too general. Also, if you're sending out a really large number of emails, it's still a good idea to do some manual checks now and then for the best possible results.
