I'm very new to this. Unfortunately I just sent out an email to over 250 clients, and I had failed to replace "Company Name" and "Website" on the template with my custom information. I would have very much appreciated some sort of red flag, a notice that this still needed my attention. Instead, I've sent the email with that generic info at the bottom, likely affecting the clients' impression of my professionalism and attention to detail. It seems it would be a very easy thing to program into your process - a red flag to point out incomplete areas of a template before clicking "Send". I'm extremely disappointed that you didn't flag me about this.
