I have been vibe-coding my little head off. I can write code to an extent, but I am not very good – so thanks to the rise of generative AI, I have been able to build a few things I have had in the back of my mind for a while.
My first mini project was a Email and newsletter tester service. I use a similar one for work all the time when i am checking the auth records of a domain – and I often run out of lookups. I was annoyed one day when it happened, so I decided to just make my own.
Mail-tester.co.uk
I was lucky enough to get this domain, which is similar to the other one I use. I started by making a note of what was important to email authentication.
- DKIM
- DMARC
- SPF
And created a system that allows you to send an email to a random address, then the email gets piped through my smtp service, into a system that analyses it and produces a report.
There were a few hurdles to overcome – the biggest being we wanted to make sure this service accepted ALL emails, even if they were flagged as spam. If it blocked emails that failed auth checks then how could we check the auth status of emails? lol.
The Result
The system itself is really basic, but it works. It doesnt check blacklists, as if it did then the bounces would clearly state that – plus if the users auth records check out, and they are still concerned – I popped a handy little form on the results page so they can email me and I can look into it for them.
Im really happy with the result, check it out here.
I’m gonna give it a redesign soon based on some new layout stuff I have been playing with, but its simple, straightforward and FREE!
YAY FREE!
