The Honest Email Marketing Calculator

When I was building a normal landing page for SimploMail.com. You know the type โ€” feature grid, pricing table, big green button I thoughtโ€ฆ no. People don't believe landing pages. I don't believe landing pages. So I decided to build a calculator and I called it "The Honest Email Marketing Calculator" because that's what it is. You tell it your list size and how often you send. It shows you what...

I still move way faster than I used to but I definitely slowed down

It really feels good to build applications using AI tools. Itโ€™s fast and it looks good! I built one myself(simplomail.com) and I love it โค๏ธ. But to keep these AI tools from breaking things, I had to write ๐˜๐—ผ๐—ป๐˜€ ๐—ผ๐—ณ ๐˜‚๐—ป๐—ถ๐˜ ๐—ฎ๐—ป๐—ฑ ๐—ถ๐—ป๐˜๐—ฒ๐—ด๐—ฟ๐—ฎ๐˜๐—ถ๐—ผ๐—ป ๐˜๐—ฒ๐˜€๐˜๐˜€.

SimploMail is different because it removes subscriptions entirely. You only pay for emails you actually send - credits never expire, and list size doesnโ€™t affect cost. Itโ€™s built for founders and creators who send occasionally, not weekly. No tiers, no monthly fees, no penalties for going quiet. Just simple, payโ€‘perโ€‘send email campaigns.

Are AIโ€‘generated UI designs good enough for production apps?

I continue building UI pages for my email marketing platform using AI, and I wondered if AIโ€‘generated UI designs are good enough for production apps? They seem to work great on mobile devices and desktop screens. They load fast. They behave normally. Iโ€™m personally perfectly fine and happy to use them in production, but what is your opinion? Am I missing something? Should I be worried about...

How I create UI quickly using Stitch + Lovable

There is a very quick way to create UI for a mobile application or a website. I used this approach to create the UI for one of my side projects. To create the design, I used Google Stitch (https://stitch.withgoogle.com/). Stitch allows you to design using prompts, then edit specific parts of the image by highlighting them and describing what to change. You can download the designs in HTML or...

Looking for feedback on pricing model for my email marketing tool

Iโ€™m building an emailโ€‘sending platform and considering a payโ€‘asโ€‘youโ€‘go model instead of subscriptions. My reasoning is that many people donโ€™t send emails every month, so charging only for usage feels more fair. However, several founders have warned me that this model may be a mistake from a business perspective. If youโ€™ve built or used similar tools, Iโ€™d appreciate your thoughts on: Whether...

Two hard days of work - one Big win. I just built embeddable Signup forms

A quick update on my email marketing platform project. I spent the last couple days working(almost non stop) on a new feature that I felt I must have before opening my email marketing platform to the public. I've implemented embeddable Signup forms. Now you can embed a little signup form right into your own website. Visitors type their email, hit send and email gets added to your subscribers...

AI can remove something important without telling you ๐Ÿ˜…

Itโ€™s the third week of working on my little side project, SimploMail.com, and to speed things up Iโ€™ve been doing a lot of โ€œvibe coding.โ€ Itโ€™s been fun, but a few things became obvious pretty quickly. I stopped using the โ€œautoโ€ model setting in the IDE. When it silently switches models, the quality drops fast. I can feel when the agent all of a sudden looses its intelligence ๐Ÿ˜…. So now I just...

Hello fellow creators ๐Ÿ™‹๐Ÿปโ€โ™‚๏ธ

My name is Sergey and I am a software developer. I am here because I started building a service I wanted to build for a several years now - A pay-as-you-go email marketing platform. I could not find a service that does not charge if I am not sending any email campaigns. So I decided to create one. Building in public is very new to me and I have zero experience sharing about it. But I will try...
