You might not be aware of this (I wasn’t until recently).
You can use your gmail username with a + after it with absolutely anything and you’ll still get the email.
Yep, for example my username is “chambly”, so I could let’s say use email@example.com and I’d still get the email.
Or firstname.lastname@example.org and I’d get the email still.
Why is this so cool?
Well you can use different combinations for different contacts you may meet, say +business, +friends, or say +spam if you want to sign up to a site but fear spam. You can then set up filters in gmail to filter your mail based on the +whatever, keeping you very organised and your precious username lean.
I love that tip, think it’s handy yourself?
