Did you know that Gmail lets you add any number of dots (.) and plus (+) signs in your email address? I didn’t. This was recently brought to my notice by a colleague, Narendra Wagh. The best part was the way Gmail conveys the fact.
This means that firstname.lastname@example.org and email@example.com are same as firstname.lastname@example.org. Wow! That will really take away a lot of confusion that dots introduce in email addresses. People find it very hard to accept when I tell them I have no dots in my email!
The other great feature is letting you use + in your email address. You won’t want to share email with + with friends, but you could definitely use it at website known to Spam you. Had this been known before, I would sign-up at Times Job (a relevant example) as email@example.com and then create a Filter in Gmail for all email from there to skip the inbox and sit inside a ‘Times Jobs’ label. A quick way to filter email is use the ‘Filter messages like these’ link available in the email header.
