Thanks for your interest in my writing
Before we get started, I've sent you a message asking you to confirm your email address (so I'll know I've got the right inbox).
Please check your email, click to confirm, and Bob's your uncle. Or maybe you'd prefer easy-peasy, a piece of cake, or et voilà! Maybe even job done?
I could go on for hours, but my confirmation email's probably arrived by now.
If it hasn't (gasp), check your spam, promotions or equivalent folder.
See you soon!
P.S. I'll be asking you to add firstname.lastname@example.org to your safe senders (whitelist me), so rather than reinventing the wheel, here's a great resource on how to do just that.
