I had the same issue. Gmail the punctuation used in the naming convention is ignored. If you have Johnny.Good@gmail.com, then JohnnyGood, Johnny-Good, Johnny_Good will all go to your account. However, Johnny.B.Good@gmail.com will go to a different account, as would other similar addresses.
It was fortunate to grab your name when invited.
I hope you can help me. I have a Gmail account that I created years ago when it was first introduced as an invite only and I have continued to use for many years with no issues. I won't disclose my email address, but as an example it something like this: firstname.lastname@example.org (note the period I am using between the first and last name).
In the last few months, I started to receive random emails. Initially I thought it was spam, but it got stranger when I started to receive personal emails not for me but someone with the same first and last name. When I looked closely at the emails I realized that the email address was sent to email@example.com (without the period). However, that's not my email address, mine has a period between my first and last name and this one didn't. These clearly are different email addresses so why am I getting their emails? Right now I'm paranoid as I'm wondering how many emails are going to the other person's email address. Any explanation to this and is it just me or are any of you experiencing this on Gmail? What can I do, besides abandoning this email account? My brain is hurting and I can't figure it out and I'm hoping that someone has an explanation. I look forward to your help. Thank you.
