Is there any issue with texting someone about an hour before sunset and saying “Good Shabbos” in the text message? Could this somehow unintentionally obligate the texter to bring in Shabbat when they say “Good Shabbos?” Thank you sincerely. Good Shabbos
You don’t have to worry that you are mekabel Shabbos by saying this. You do not mean to accept Shabbos this way.
Have a good Shabbos
