I have a quite common (in my country) name and surname, so I have a personal email address that is like firstname.lastname@example.org, the country suffix added because john.smith was already taken. It is easy to remember (unlike plain numbers) and unchanging.
Unfortunately, when I have to dictate it to other people, they sometimes forget the last part, so any message that I was going to be sent would inevitably get lost. This happens especially when I have no means of checking whether they have written down the address correctly, e.g. when speaking at the phone. Sending the email address by SMS doesn't work either because they may copy it wrong (it happened too). In informal contexts (e.g. with friends) I often make a quick remark: "hey, don't forget the '.uk'!" when dictating the address, but I fear it could be a little condescending in other semi-formal situations, like:
- a landlord
- a trusted stranger who has to send me some document
- an employee at bank/insurance/etc.
How I can ensure they got correctly my address without sounding condescending?
