24 alternatives to I made email validation tool
Hey HN, I’m a solopreneur and have been in the SaaS space for the past 3 years. My last 3 startups failed, and a common challenge in all of them was figuring out how to reach my audience. Recently I started with cold outreach (its a struggle, since I dont have much experience with marketing). I am finding leads mainly using exa.ai websets (web vector search, extremelly good for multiple use cases, recommend checking them out) and then sending them through smartlead. I ran the campaign for the past 30 days and 12-15% emails always bounced. This wasted my email credits & chances of reaching…

Overlead▲146Here's the problem: I launched two products. I wrote blog posts. I posted on X, built in public. I tried running ads. And you know what actually got me customers? Replying to someone on Reddit who asked, "What's the best tool for this?" One reply. Three signups. I felt like an idiot for not doing it sooner. But here's the issue: I don't have time to refresh Reddit all day looking for these posts. I have products to build. Bugs to fix. Emails to answer. Life to live. So I built Overlead to do the searching for me. Overlead scans Reddit, Quora, and Hacker News (and many more to come) for…

Hey HN, I'm a bootstrap SaaS founder that trying to grow my micro SaaS. I've been doing pivot many times and this may be the last straw. I realized that marketing and sales are key in building business but cold outbound is suck! So I built a tool to help SaaS founders identify unhappy customers from their competitors to pitch their SaaS. This feature is specifically requested by Peer - Cal.com CEO from my interaction with him here - https://x.com/heykaiyo/status/1821216800610382013 I hope this small tool would be helpful. Would love your feedback pls. Anyone…

Hey HN, I’m Kyrylo. I recently created a small tool that lets you gather, refine, and validate SaaS/startup ideas using AI. I used to jot down my product ideas in a note apps, but it wasn’t very practical for collecting feedback or refining them. So, I built this tool to make the process easier. Here’s how it works: 1. Enter a brief description of your idea. 2. The app uses AI to generate project details. 3. Share your idea via a link that includes a feedback form. It’s pretty straightforward, and I’d love to hear your thoughts or any suggestions!

Hi HN! I'm Louw, founder of the enterprise insurtech scale-up Root[0]. Over the last 8 years, my inbox has been flooded with unsolicited emails, especially since early 2023. Recruitment services, outsourced software development agencies, and a crazy amount of lead generation services (thanks, Apollo!) drowned my inbox. To solve this, I created Unspam. Initially, it was a simple tool for myself and fellow founders to reduce noise. And it worked — about 10% of my emails were swiftly and accurately categorized as unsolicited messages. Given its success, I've decided to package and share Unspam…

Hi there, So a buddy a couple of days ago came up with the idea for a new SaaS product regarding gpt and image generation. We did a quick MVP that barely works, it breaks almost 50% of the time but we still wanted to validate the idea before going all in. We have almost 1k followers on Twitter together. Did a quick post describing the idea with a stripe link in the comments with a 5$ value, no landing page, and no shipped product. In exchange, the buyers become beta users. Around 30 mins later we got our first sale next 30 mins another 5$ and so on. Do we consider the idea validated? The…

I was working on validating some of my own project ideas. While trying to find how to validate my idea, I realized the process itself could be turned into a tool. A few late nights later, I had something that takes any startup idea, fetches discussions, summarizes sentiment, and gives a quick “validation score.” It’s very rough, but it works, and it’s already making me rethink a few of my own ideas. It's still a work in progress. I don't actually know what I'm doing, but I know it's worth it. Honest feedback welcomed! Live demo here: https://validationly.com/

Resletter▲13I’ve launched a few SaaS products before, but this time I built something I’m genuinely excited about. I kept seeing a real pain among SaaS founders and devs: email marketing. If you run a SaaS and you’re not using email marketing, you’re honestly missing out. It’s still the best way to engage and retain your users. That’s why I built Resletter, an email marketing platform made specifically for SaaS founders and developers. No bloated UI, no unnecessary complexity like Mailchimp, Brevo, or other traditional email marketing tools. Don’t believe me? Try the free plan, connect your Resend…

I do cybersecurity consulting, so I do outreach every single day, and as you probably know, cold LinkedIn outreach usually has a very low response rate. I've also started launching SaaS products, and I know people running Etsy shops and e-commerce stores and getting users, even for free SaaS, is hard. Meanwhile, people publicly ask for products and services every day on social media. That's why I launched ReachFast: 1. You enter your SaaS website, Etsy shop, App Store /Google Play page, Fiverr profile, even a Skool community link 2.No settings, no keywords, no linking your social…

I'm tired of seeing founders building stuff for months and years that nobody would ever pay for. They just don't see it, like most other founders learn to do. Business validation = making money, and nothing else really. If you really wanna make money this year, I can help you do it.

Hey HN, I’ve been working on ElevateSells — an AI sales agent designed to take the pain out of cold outreach for solo founders and small teams. Here’s how it works: You ask the AI to generate leads or manually use the advanced lead search built in tool. You tell the AI what your business does and what problem it solve. It writes very personalized cold emails, sends them, and follows up — all automatically. You still control the voice and audience — the AI just handles the research, writing, timing, and sending. I built it after burning out managing multiple tools for lead gen, email copy,…

When I was learning about cold emailing, I was looking at the tools for it, they were nice but a bit pricey. I decided to build my own, and I achieved good reply rate with it. It uses Google maps to find leads, you can specify location and categories. I got my first good results the other day. From 500 leads, I got 250 opens and 10 replies. The email leads are checked with two different api's to ensure they are deliverable. The emails are sent from pre warmed ip's, so you wont land in spam. You can also upload your own leads. You can personalized mail merge write once / use lead…

Hey HN, I've just begun my solopreneur journey. I've been a "serial starter" - often starting projects and never seeing them through, and I have finally finished my first project! Maybe this sentiment resonants with some of you, let me know in the comments below I built this tool as a simple no-risk method for turning more visitors into customers by A/B testing your sale promotions and automatically displaying the promotion with the highest conversion rate. Did you know that increasing your conversion rate by just half a percent can have a dramatic impact on your sales without needing…

Hi everyone. Over the weekend, I built a tool for finding contacts using AI. Here's the backstory. My partner and I are working on an agrotech startup – we’re building telematics for agricultural machinery. Most of our sales come through cold outreach: you search for contacts, message them, call, make deals and so on We also do indiehacking, because agrotech is slow and a sometimes boring. At some point, we got tired of manually collecting contacts from the internet, so we built a AI tool for that. It turned out to be super helpful, and we decided to share it with the world. If anyone here…

Hi HN, I created a (realistic) fake tweet generator to make my mum believe I'm successful until I get there for real haha. Now I can proudly (not) show her Elon endorsed my SaaS! It's 100% free to use and I tried to make it as realistic as possible while being easy to use. There are already existing similar tools but I could not find one that automatically pre-fills data from a twitter username and that handles business accounts (square picture/gold badge/company picture) so I built it. I would love to hear your feedback or suggestions!
