I wonder if you take the time to check the location of a person you are emailing?
Too often I get emails that are directed to me personally, and are not part of a bulk email, where the person says ‘have a great day’, or ‘hope you’re having a great summer’ when the reality is I live on the other side of the world to that person so it’s night not day and winter not summer.
Do you think I’m being pedantic? I don’t believe so. When I email someone and if I’m going to make reference to the time of day or season, I actually take the time (a few seconds is all it takes) to visit their website and check their location, if it’s not evident in their email signature block.
Taking the time to consider the person you’re emailing doesn’t require a lot of effort but it does help personalise the contact and demonstrate that you are aware of their personal locality, rather than throwing out a generic or blanket greeting. It’s just possible it may make the difference between you building a relationship with that person or not having any further contact.
