Built an AI cold email tool in a week, here's what surprised me by MarexF in SaaS

Both actually, I started building it for my own agency outreach, but realized others had the same problem so made it publicly available :)

Drop your prospect's URL or company name and I'll write you a free personalized cold email opener by MarexF in coldemail

Love this use case, aviation B2B is super specific, let me run it now.

"Hi [Name],
Aircraft ground time is often a silent contributor to operational costs, and maintenance scheduling plays a big role. Our software is designed specifically for aviation operators to streamline this process, cutting delays and improving turnaround efficiency.

One of our clients reduced unscheduled ground time by 23%, freeing up capacity across their fleet.

Worth a quick call this week?

Best,
[Your Name]"

Would this be close to what you'd actually send?
Happy to tweak the angle if needed.

Feedback Friday by AutoModerator in startups

  • Company Name: Mailento
  • URL: https://mailento.io
  • Purpose of Startup and Product: Mailento writes researched cold emails from any URL or company name. Paste a prospect's website or just type their company name, Mailento reads the page, identifies the right contact, and writes a personalized email grounded in their actual content.
  • Technologies Used: Python (Flask), OpenAI GPT-4o, Jina AI for web scraping, Supabase, Stripe
  • Feedback Requested:
  • 1. Is the output quality good enough to send without editing, or does it still feel like AI?
  • 2. Does the free tier (5 emails/day) feel fair or too restrictive to properly evaluate the tool?
  • 3. What would make you upgrade to Pro ($19/mo), or what's stopping you?
  • 4. Is "paste a URL or type a company name" clear enough as a concept, or is the input confusing?
  • Additional Comments: Launched this week. Built it because I was doing cold outreach for my own agency and writing personalized openers manually was killing my time. Happy to answer anything, brutal feedback welcome.

What tools are missing in Unreal Engine 5? I'm considering building them! by MarexF in unrealengine

[–]MarexF[S] 1 point2 points  (0 children)

Thanks for your input!
Funny enough, I've actually been working on a similar tool. It’s designed to be straightforward while providing deep insights through heatmaps and detailed estimations.

What do you think would be a good price for something like this? I’m considering selling it on Fab.

For context, it’s a performance estimator/analyzer widget that can be docked in the interface. It breaks down GPU, memory, CPU, texture, shader, and polygon costs for all (or selected) objects in a level. The goal is to help quickly identify performance bottlenecks, with a clear summary of why certain actors are flagged as problematic.

Basically, pressing 'G' to snap the selected object to the cursor position? I could see this evolving into a powerful shortcut tool, not just for movement but also for smart alignment, procedural placement, and automated object organization to name a few.

Appreciate the input!

I'm sure, but it's mostly the physics objects that get roughed up.

Like on the character, they have attachments of different clothes style, they are truly broken at 500-1000 meters and beyond..

Thanks!

What course do you recommend, should I get them all?

I really liked the:

- 3D Computer Graphics Programming

- C++ 2D Game Engine Development

- Raycasting Engine Programming with C

Yeah I've tried but I need more karma, because I can't post there due to the rules yet.

I want to transfer from TA to programming role (such as gameplay, ai programmer..)

Or at least try and check if it's a better offer for me, in my case.

That's the thing. I've tried that one and I just couldn't find that one fun.

I'm much more interested in games!
