@maclein, Sorry for the issue you faced. The tool checks if an email is reachable by querying the MX servers and returning the result based on their response. For gibberish email IDs, one way to test would be to send an email and see if it goes through, but that’s not ideal. I’ll look for a better approach to handle this.
Thank you for your valuable feedback. I’ll work on fixing this issue.
Congrats on the launch! Looks promising, but why free?
BTW, it doesn't seem to catch temp / disposable mails. I tried via emails from https://temp-mail.org/en/
@ohansemmanuel thank you for the upvote and feedback.
I maintain a growing list of disposable domains against which to compare emails, and new domains are added daily. As the list expands, you should notice improvements in detection over time.
As for the tool being free, I believe it should be, given that it's built primarily on open-source projects. My infrastructure costs are minimal since I don’t store any data, eliminating the need for a database and its management. For backend hosting, I use railway.app, which provides sufficient resources to run my APIs for a minimal cost.
The only way to cover the costs is by running developer-focused ads.
@snayak , fair enough. Thanks for the detailed reply! I'll give it a closer look!
QQ: Do you plan to add auth headers to the API? i.e., it can still be free, but this lets you do things like rate limiting for a fair usage policy / finer control over who's using the API
Just a thought!
I'll try the API in some of my projects.
@ohansemmanuel The goal is to make the API accessible to everyone without requiring sign-ups or API keys. However, as you suggested, I may consider an alternative way to implement auth headers.
I appreciate the great suggestion!
Impressive product for validation purposes with comprehensive checklist available.
