Do you say “Dear Mr.(or Ms) LastName:” as in the old style or “Hello” or something else like a memo style?

What are the essential things to include on today’s e-mail business correspondence (not including the body of the letter)?

Your advice appreciated always

I interviewed for a position and was emailed about a time for a second interview. I replied back but have not heard back. How many business days should I wait to follow up with them about the unanswered email?

I need to be non-offensive as she also sends me the occasional client, but she is out of control with the “forwarding” emails.
And I can’t tell which are which as the email “re” is always blank.

Give me some examples of salutations you use to end professional emails. I **** using the same ones every time. Some I currently use are:
Best regards,
With best regards,
Thank you,
Cordially,
Kindest regards,

I’d like to use something different! Give me your examples!

I send out a lot of emails to business clients, but I have a jewelry business, so it’s more personal. What’s a good ending salutation for informal business emails?

I went back to my maiden name after getting divorced. I want everyone outside of my company to know that it’s still me when they email me or receive an email from me. I have heard that you should write it as :

Jane Doe (f.k.a Smith). Doe being the maiden name and Smith being the former married name.

Does anybody know if this is correct?

I notice that people will patronize a business even though the people who operate the business are rude. There is this restaurant in my area that has awesome, delicious food but the waitresses are rude and my coworkers insist on going there even though they too complain of the less than stellar service. I understand that the food we get at this restaurant isn’t served at many other places but the service is ridiculous. Do you support businesses that are run by rude people or do you flat out refuse to support such businesses? Please…no rude or sarcastic answers. Thanks.
