Mailwarm's answer
Mailwarm started as a real problem we faced ourselves.
We were two founders working at Station F in Paris, the largest startup incubator in Europe, trying to sell our own products. Every time we launched outreach campaigns, our emails kept landing in spam.
To solve this, we built an internal email warmup system for our personal use. After deep research into email deliverability, we created a stronger, more reliable solution.
Other startups in the incubator quickly asked to use it too; so we turned it into a real product.
After launching publicly, Mailwarm became #1 Product of the Day on ProductHunt and was accepted into Y Combinator, the worldโs most prestigious startup accelerator.
Since then, Mailwarm has grown into a trusted platform used by thousands of companies to improve inbox placement and email deliverability.

I decided to try Mailwarm after having consistent issues with my emails landing in spam folders. At the beginning, I wasnโt fully sure what to expect, but the onboarding process was simple enough to get me started quickly. After running it for a while, I began to notice a steady improvement in my email deliverability. More of my messages started reaching the inbox instead of getting filtered out, which really helped with my outreach efforts. Overall, itโs been a reliable experience.

This is not opera.com it's "api2 dot com" so it's a malware site posing as an opera one by including opera in its name. I had a popup like this. It opened every time I opened the browser. Turned out it was coming from a video downloader extension. Source: about 3 years ago
The opera.com domain is banned where I live but I still want to download the browser without a VPN (because those are also banned). Is there a torrent link or an alternative/mirror link where I can download the latest Opera One release? Thanks! Source: about 3 years ago
Apparently it "urgently needed to be removed off the network" (bullshit, you could've blocked opera.com, dumbass) I don't see why its so bad to have one kid with an unmanaged browser, like seeing "your browser is managed by your organisation" sucks enough. They disabled basically everything good about Chrome, for a time, they locked down the performance tab so we couldn't even use battery saver. Source: about 3 years ago
One day, I got called to my Deputy Principal's (Dep. For short) office because my laptop was doing wacky shit to the network. He informs me that my laptop had sent 64k pings to opera.com. It was about the 2nd term, we receive new laptops every couple of years. He first told me about my searches for a VPN, which I guess is on me. But when he brings up the 64k pings, he tells me whatever the app is doing it has to... Source: about 3 years ago
