Two responses Unless you are expressly addressing one individual or group in an email that is CC'd to others, it is recommended to leave off any salutation. When greeting everyone equally, saying "hello all" or "all" feels as strange as starting a newspaper story that way. This is, at best, folky.
Greetings to groups through email
Pachter suggests writing, "Hi everyone," if you're addressing a group of individuals. Greetings with caution"Hey! According to Pachter, it's hardly professional, especially if you're writing to someone you've never met. He or she might think that you are trying to be cool by starting emails with such phrases as "hi", "g'day", or "y'all". This is especially true if you do this frequently. It's best to write formal letters using proper grammar and spelling.
Hello [Name], When you put "there" in the [Name] box, your receiver will receive a generic greeting: "Hi there." Here's a pro tip: use caution when using mail merges and bulk emails. Using simply first names is typically your best bet. It's easy to write "Dear John" one letter at a time and send it out. However, if you write "Dear John," then click Send, your email program will merge all of these letters into one large message that could get flagged as spam.
Spammers often use fake names in their messages to make them appear more legitimate. So, if you do want to write a personalized opening, do so but be careful not to give away too much information about yourself or your business. For example, don't write "Hello Mr. Smith!" instead write something like "Hello, I'm an auto dealer in town who was just looking at cars recently. Would you like me to help you find something?"
Also note that some people may prefer not to know who sends them emails. If this is the case for you or your recipient list, please be sure to sign your emails “from” so they do not think it comes from someone else.
Have a great day!
This is OK to use with friends, but the highly informal salutation should be avoided in the workplace. It's unprofessional, especially if you're writing to someone you've never met, according to Pachter.
In most cases, it is best to avoid greetings. "Hey!" According to Pachter, it's hardly professional, especially if you're writing to someone you've never met. He says it makes you seem unimportant and less credible.
He adds that it can also be interpreted as a sign of hostility toward your reader. So, whenever possible, try to be more formal and respectful. After all, you want your readers to feel like they are important and valued, right?
Well, according to multiple sources (including Pachter), it is not only acceptable but also advisable to start emails with "Hello". One reason why people do this is because they are not sure who will read their messages. They want to make sure that everyone sees their contact information so that they do not receive complaints about being contacted when they are not available to be called.
Another reason may be that the sender does not have anything special to say but still wants to let the recipient know who he/she is. In other words, it is a way of introducing yourself or your company without appearing pretentious or arrogant.
Last but not least, some people enjoy making others feel welcome and appreciated. Using "hello" shows that they take the time to think about others and that makes them feel good inside.
