I came across a very strange feature of Gmail, I am not 100% sure whether it is a feature or not.

The below email address are valid for a given email address devank007@gmail.com:

  1. devank.007@gmail.com
  2. devank0.07@gmail.com

How many such cases are there where any email provider accepts these?

  • I'm pretty sure it is only Gmail that exhibits this behaviour. I've never seen it elsewhere – Daniel Sep 04 '16 at 08:45

  • It would be better if you also add [tag:amazon-ses] tag and add a little note of your issue of sending email to `user@gmil.com` and `user@gmailc.om` in the question. – Ajeet Shah Sep 04 '16 at 16:44

Google doesn't treat the . as a character in their email addresses. Hence hikingfan@gmail.com, hiking.fan@gmail.com or hi.kin.g.fan@gmail.com refer to the same email address.

And somewhat similar is true with using + in your Gmail addresses, for example, hikingfan+banks@gmail.com, hikingfan+coding@gmail.com or hikingfan@gmail.com refer to the same email address.

These features of Gmail might help you easily create various filters. Note that the same might not be true for other email service providers.
