A little project - Email to WebMail URL API

03 Mar, 2024

Recently, I developed a Email To WebMail API that given an email (or domain should you not want to provide an email for privacy reasons) can return the webmail URL for that user.

My idea with this is that doing so will allow websites to provide a fast link for users to check their emails while signing up and doing email verification. This will probably not be so useful on mobile, but I've already seen plenty of implementations of similar for mail apps for mobile as it's the more common platform nowadays. I still think we should try and bring this convenience to the "old fashioned" web.

Currently, I've managed to make it support the following services (as far as I can tell):

Gmail
GSuite
Outlook.com
Outlook.com for Business (Office 365)
MailInABox
ProtonMail
FastMail

I would've added Mimecast (a common phishing protection measure in the UK at least) but it appears that it works with G-Suite and Office 365, so it is impossible to tell which service is behind it.

I also included a search URL for mail providers that support it, so that you could search for the appropriate subject line in the user's mailbox to help them find your confirmation email - obviously just don't put the code in the search if it's in the subject line haha.

If your mail provider is not supported, feel free to Submit an Issue including the inbox and search URLs ideally, so that I don't have to sign up to that service (although I will if I am able to). I'm happy to figure out how to identify it so long as you provide example domains that they send/receive email from/to.
