There is no definitive answer to this question since different people have different preferences and opinions. However, if you are looking for a good day to send a newsletter, there are a few factors to consider.
First, you should consider the recipients’ schedules. If the recipients are busy people who are not able to check their email frequently, then sending a newsletter on a weekday may be a better option.
Additionally, if you have a large subscriber list, you may want to send your newsletter on a weekday so that it reaches as many people as possible.
Second, you should consider the weather conditions. If it is cold outside or raining, sending a newsletter may be difficult because people will not be able to open their emails in those conditions.
Alternatively, if it is hot outside or sunny, sending a newsletter may be more difficult because people will be outdoors and likely not wearing jackets or hats.
Finally, you should consider the topic of the newsletter. If the topic of your newsletter is controversial or sensitive, it may be better to wait until after the holiday season has passed so that the recipients are less likely to get offended.
